# Personal Trainer (by Mobile Squad): Full Documentation > Offline gym workout tracker. Custom plans, set/rep tracking, smart progressive overload, friends mode. One-time VIP Premium unlock (no subscription). Android app, all data on-device. **Canonical URL:** https://mobile-squad.com/apps/personal-trainer/ **Compact index:** https://mobile-squad.com/apps/personal-trainer/llms.txt **Last updated:** 2026-05-23 --- ## Core concept A workout tracker focused on programming + logging, not subscription content. Build your own plan, log sets/reps/weights, app suggests progressive-overload increments based on completion. Offline-first, works in basement gyms with no signal. --- ## Page 1: How to build a push / pull / legs split URL: https://mobile-squad.com/apps/personal-trainer/how-to-build-push-pull-legs-split/ ### Why PPL Hits each muscle group ~2× per week on a 6-day cycle, with 48 h recovery between same-muscle sessions. Good middle ground between full-body and bro-splits. ### Sample template - **Push (chest/shoulders/triceps):** flat bench, overhead press, incline DB, cable fly, lateral raise, triceps push-down. - **Pull (back/biceps):** deadlift or pull-up, barbell row, lat pull-down, face pull, hammer curl, EZ-bar curl. - **Legs (quads/hams/glutes/calves):** squat, RDL, leg press, walking lunge, leg curl, calf raise. ### Volume & intensity - 12–18 hard sets per muscle per week. - 3–10 RIR (reps-in-reserve) per set, mostly 1–3. - Progressive overload: add 2.5 kg or 1 rep per session for compounds, 1 kg / 1 rep for isolations. ### Frequency - 6-day: PPL/PPL/rest. - 4-day: PPL + upper or PPL + full-body. - 3-day: PPL once through (lower volume). --- ## Page 2: For home-gym lifters URL: https://mobile-squad.com/apps/personal-trainer/for-home-gym-lifters/ ### Minimum-viable home setup - Squat rack or half-rack. - Olympic barbell + ~150 kg of plates. - Adjustable bench. - Pull-up bar. - Resistance bands for assist + warm-up. ### Substitutions when kit is limited - Lat pull-down → band-assisted pull-up. - Leg press → high-bar back squat or front squat. - Cable fly → DB fly + band fly. - Face pull → band face pull. ### Programming notes Home gyms reward compounds. Lean program to squat, deadlift, bench, press, row, pull-up. Add 1–2 isolation per session via DB. --- ## Page 3: Personal Trainer vs Strong app URL: https://mobile-squad.com/apps/personal-trainer/vs-strong-app/ | | Personal Trainer | Strong | |---|---|---| | Pricing | One-time VIP Premium unlock | Subscription | | Offline | Yes, fully | Mostly | | Plan builder | Yes | Yes | | Smart overload suggestions | Yes | Limited | | Friends mode | Yes | No | | Wear OS | Yes | Limited | Strong has a beautiful UX and large library. Personal Trainer prioritises offline reliability, owning your data on-device, and a one-time payment model. --- ## Page 4: Personal Trainer FAQ URL: https://mobile-squad.com/apps/personal-trainer/faq/ **Q: Is it free?** Free with VIP Premium one-time unlock for advanced features.

Data stored in localStorage, no sign-up, no server. Includes a Chart.js bar chart showing weekly volume trends per muscle group, so lifters can visually confirm progressive overload is happening. ### What the tool does - **Input:** date, exercise name, muscle group, sets with reps and weight (kg or lbs) - **Output:** weekly volume per muscle group (aggregated from all logged exercises), stacked bar chart, current-week summary cards - **Unit toggle:** kg ↔ lbs (converts all stored weights on switch) - **Persistence:** localStorage key `pt-vol-calc-v1`; no account required; Reset button clears all data ### Volume definition Volume = Sets × Reps × Weight. A bench press session of 3 sets × 8 reps × 80 kg = 1,920 kg of chest volume. ### Evidence-based weekly volume targets (sets/week, intermediate lifters) | Muscle group | MEV | MAV | MRV | |---|---|---|---| | Chest | 8–10 | 12–20 | 22+ | | Back (Upper) | 10–12 | 14–22 | 25+ | | Shoulders | 8–16 | 16–22 | 26+ | | Biceps | 8–14 | 14–20 | 26+ | | Triceps | 6–10 | 10–18 | 22+ | | Quads | 8–12 | 12–18 | 20+ | Source: Renaissance Periodization (Israetel et al.) ### Progressive overload methods tracked Load progression, rep progression, set progression, frequency progression. All increase weekly volume total. ### Deload guidance Plan a deload every 4–8 weeks: cut volume to ~50% of peak while maintaining intensity. Volume typically rebounds above pre-deload peak post-deload (supercompensation). --- ## Page 6: 1-Rep Max Calculator & Percentage Chart URL: https://mobile-squad.com/apps/personal-trainer/one-rep-max-calculator/ ### TL;DR Enter a weight and rep count to get your estimated 1RM from four validated formulas (Epley, Brzycki, Lander, O'Conner). The tool generates a full percentage chart (50%–100% of 1RM in increments) for planning training loads by zone. ### What the tool does - **Input:** Weight lifted (kg or lbs), reps performed (1–15) - **Output:** 1RM estimates from all four formulas + average; percentage chart with zone labels (Strength / Hypertrophy / Endurance) - **Persistence:** localStorage key `pt-1rmcalc-v1`, no account required - **Formulas:** Epley: w×(1+r/30); Brzycki: w×36/(37−r); Lander: w/(1.013−0.0267123×r); O'Conner: w×(1+0.025×r) ### Training zones - Strength: 85–100% 1RM (1–5 reps) - Hypertrophy: 65–85% 1RM (6–15 reps) - Endurance: <65% 1RM (15+ reps) --- ## Page 7: Rest Interval Calculator & Timer URL: https://mobile-squad.com/apps/personal-trainer/rest-interval-calculator/ ### TL;DR Select training goal (Strength / Hypertrophy / Endurance), exercise type, and experience level. Get evidence-based rest interval recommendation with min/mid/max options. Built-in live countdown timer with circular progress ring. ### What the tool does - **Input:** Training goal, exercise type (compound-heavy / compound-moderate / isolation / superset), experience level - **Output:** Recommended rest range (seconds) + live countdown timer - **Persistence:** localStorage key `pt-restcalc-v1` - **Reference:** Schoenfeld BJ et al. (2016): 3-min rest > 1-min rest for hypertrophy ### Rest ranges (compound heavy, intermediate) - Strength: 180–300 s (3–5 min) - Hypertrophy: 120–180 s (2–3 min) - Endurance: 45–75 s --- ## Page 8: Barbell Plate Loading Calculator URL: https://mobile-squad.com/apps/personal-trainer/barbell-plate-calculator/ ### TL;DR Enter target total weight and bar weight. Calculator uses greedy algorithm (largest plates first) to determine exact plates per side. Visual barbell diagram shows loading order. Supports kg (full/standard/basic plate sets) and lbs. ### What the tool does - **Input:** Target weight, bar weight (20/15/10/25/0 kg), available plate set - **Output:** Plates per side list, total loaded weight, shortfall if not achievable, visual barbell diagram - **Persistence:** localStorage key `pt-platecalc-v1` - **Algorithm:** Greedy: largest available plate first, decrement remainder, repeat ### Standard plates - kg: 25/20/15/10/5/2.5/1.25 kg (IWF colours: red/blue/yellow/green/white/black/chrome) - lbs: 45/35/25/10/5/2.5 lbs --- ## Page 9: TDEE & Macronutrient Calculator URL: https://mobile-squad.com/apps/personal-trainer/tdee-macro-calculator/ ### TL;DR Mifflin-St Jeor BMR formula × activity factor = TDEE. User selects goal (muscle gain +300 kcal / maintenance / fat loss −400 kcal / aggressive cut −700 kcal). Calculator distributes target calories into protein (2.0 g/kg, 2.2 g/kg on cut), fat (25%), and carbs (remainder). ### What the tool does - **Input:** Sex, age, weight (kg or lbs), height (cm or inches), activity level, goal - **Output:** BMR, TDEE, target calories, macro breakdown (g and kcal per macro), ratio bar - **Persistence:** localStorage key `pt-tdeecalc-v1` - **Formula:** Male BMR = 10w + 6.25h − 5a + 5; Female = 10w + 6.25h − 5a − 161 ### Activity multipliers - Sedentary: ×1.2 | Lightly active: ×1.375 | Moderate: ×1.55 | Very active: ×1.725 | Extremely active: ×1.9 --- ## Page 10: Fitness App Statistics & Privacy Trends 2026 URL: https://mobile-squad.com/apps/personal-trainer/global-fitness-app-statistics-2026/ ### TL;DR Global fitness app market reached $15.9B in 2026. 68% of users are concerned about health data privacy. 41% cancelled at least one fitness subscription in 2025. Offline app search terms grew 43–134% from 2023–2026. ### Key statistics - Market: $15.9B 2026, up from $13.8B 2024 (14.7% CAGR since 2020) - Privacy: 68% of users concerned about health data (IAPP 2025); up from 52% in 2022 - Subscription churn: 11.7%/month in 2025 (up from 8.2% in 2023) - "No subscription gym app" search volume: +114% from 2023 to 2026 --- ## Page 11: Why Offline Workout Tracking Is Growing in 2026 URL: https://mobile-squad.com/apps/personal-trainer/offline-workout-tracking-digital-detox-2026/ ### TL;DR 37% of gym-goers report monthly connectivity issues. Smartphone use between sets reduces subsequent set volume by 16.5% (Journal of Sport and Health Science, 2022). Privacy incidents and subscription economics drive additional offline adoption. ### Key findings - Gym connectivity: 37% monthly connectivity issues; 18% delayed logging; 12% forced sync interruptions - Focus: 16.5% volume reduction from phone-mediated interruptions during rest (JS&HS, 2022) - Privacy incidents: Strava military base exposure (2018); insurance integration; data broker resale - Economics: a monthly subscription compounds over five years, while a one-time purchase costs the same regardless of use --- ## Page 12: Strength vs Hypertrophy: 2026 Science for Natural Lifters URL: https://mobile-squad.com/apps/personal-trainer/strength-vs-hypertrophy-2026/ ### TL;DR The rep-range myth has been largely debunked: hypertrophy occurs across 3–30 reps when taken close to failure. Key differences remain in rest, periodisation, and frequency. Natural lifters benefit more from twice-weekly frequency and must stay closer to failure than enhanced athletes. ### Key research - Schoenfeld 2017: 3×10 @ 70% 1RM ≈ 7×3 @ 85% 1RM for hypertrophy - Ralston 2024 meta: Volume sweet spot 10–20 sets/muscle/week for natural lifters - Pedrosa 2024: Stretched-position loading superior for muscle growth - Natural MRV: 10–22 sets/muscle/week (vs much higher for enhanced athletes) --- ## Page 13: Home Gym Equipment Pricing & Inflation 2026 URL: https://mobile-squad.com/apps/personal-trainer/home-gym-equipment-pricing-2026/ ### TL;DR Home gym equipment has largely recovered from the 2020–2021 pandemic price spike, now running 7–20% above 2019 baseline. Iron plates +20%, budget power rack +9%, adjustable dumbbells +10%. Used market remains 40–55% cheaper than new. ### Budget tiers 2026 - Tier 1 (minimalist): ~$500: dumbbells + bench + pull-up bar - Tier 2 (barbell): ~$1,500: barbell + 300 lbs plates + budget rack + bench - Tier 3 (full): ~$4,000: competition barbell + bumper plates + quality rack + dumbbell set --- ## Page 14: Best Exercises Per Muscle Group 2026 URL: https://mobile-squad.com/apps/personal-trainer/best-exercises-per-muscle-group-2026/ ### TL;DR Ranked by EMG data, hypertrophy RCTs, and stretch-position loading research. Top exercises: Chest, incline DB press; Back, lat pulldown; Quads, leg extension + back squat; Hamstrings, Romanian deadlift; Shoulders, barbell OHP; Biceps, incline curl; Triceps, overhead triceps extension. ### Key findings - Stretch-position exercises (incline curls, leg extensions, RDL, overhead triceps, incline DB press) rank highly due to Pedrosa 2022/2024 research - Leg extension ranks #1 for quads based on rectus femoris growth data, surprising to many traditional programs - Overhead triceps extension ranks #1 for triceps due to long head stretch position - Incline dumbbell curl ranks #1 for biceps (superior to barbell curl in stretch-position studies) --- ## Page 15: Personal Trainer vs Hevy URL: https://mobile-squad.com/apps/personal-trainer/vs-hevy-app/ ### TL;DR Verdict: Personal Trainer wins on automated progression, offline-first design, and pay-once pricing (VIP Premium). Hevy wins on its social feed, web app, and watch support on both Android and iOS. ### Key differences - Personal Trainer applies progressive overload automatically between sessions; Hevy logging is manual unless following a purchased program. - Personal Trainer works fully offline with no account; Hevy requires an account and syncs to the cloud. - Personal Trainer is a one-time unlock; Hevy is a recurring subscription for its Pro tier. - Hevy has a social feed for sharing workouts and a companion web app; Personal Trainer has neither, by design, to keep the app focused and private. --- ## Page 16: Personal Trainer vs JEFIT URL: https://mobile-squad.com/apps/personal-trainer/vs-jefit-app/ ### TL;DR Verdict: Personal Trainer wins on no ads, no account wall, automated progression, and pay-once pricing. JEFIT wins on raw exercise database size and its community program marketplace. ### Key differences - JEFIT's free tier shows ads and gates several features behind an account and subscription; Personal Trainer has no ads and no account requirement at all. - Personal Trainer's progression logic adjusts sets/reps/weight automatically; JEFIT's free tier relies on manual logging against a huge exercise library. - JEFIT's community marketplace offers many third-party programs; Personal Trainer ships a smaller, curated set of plans designed around progressive overload. - Personal Trainer is a one-time unlock; JEFIT Elite is a recurring subscription. --- ## Citation - **App name:** Personal Trainer - **Publisher:** Mobile Squad: https://mobile-squad.com/ - **Founder:** Erwan Alliaume - **Canonical URL:** https://mobile-squad.com/apps/personal-trainer/ Last updated 2026-08-12. --- # Full page text Everything below is the complete readable text of the 17 pages under /apps/personal-trainer/, generated from the pages themselves so this file matches what it promises: the whole app in one fetch.

He doesn't have a coach and doesn't want a subscription. Here's what his Monday push day looks like inside the app. 6:45 PM · Arriving at the gym Marcus opens Personal Trainer in the locker room. His push plan loads instantly, no login screen, no feed, no ads. He sees bench press is first, with last week's numbers pre-filled: 80 kg × 5 reps. The app flagged his right chest as still in the 24-hour recovery window, so it reminds him to warm up before loading. 7:00 PM · First working set He logs 80 kg × 6. The app catches the new rep PR and marks it automatically. He rates the set "moderate" on difficulty. When he taps rest, the audible 90-second timer starts, the screen dims so it doesn't bother the person at the next bench. 7:45 PM · End of session Marcus logged 6 exercises, 18 sets. The session summary shows total volume (4,620 kg lifted), three PRs, and a muscle recovery update. Next time he opens the app, bench press will suggest 82.5 kg, one standard plate step up, based on how he rated that last set. No guessing, no spreadsheet. Weekend · No signal Marcus travels for work. He's at a hotel gym with no Wi-Fi and his data is capped. Personal Trainer opens the same as always, all plans, all history, all suggestions stored locally. He logs the session, it syncs later when he reconnects. Nothing was lost. #### What Personal Trainer doesn't do Knowing what a tool won't do saves you time. Personal Trainer is deliberately focused. ##### No AI form analysis The app doesn't use your camera to assess movement. It provides written form cues and a one-tap YouTube link per exercise, but real-time video feedback is not part of it. For video coaching, you'd pair it with a replay tool. ##### No built-in nutrition tracking Personal Trainer tracks sets, reps, and load, not macros or calories. If you need a food log, use a dedicated app alongside it. The two concerns are separate, and mixing them tends to make both worse. ##### No live coaching or community feed There's no social feed, no comment section, no in-app personal trainer to message. The friends leaderboard compares totals, it's competition, not coaching. If you want a human coach reviewing your programming, that's a different product. ##### No subscription This is a feature, not a limitation, but worth stating clearly. VIP Premium is one payment, forever. There's no monthly tier to cancel, no paywall that grows over time. The price you see is the price you pay, once. #### FAQ Does Personal Trainer work offline? Yes. Workout data is stored locally on your device. Cloud sync is optional and only runs when you are online. Is there a subscription? No. The free tier covers the full workout experience. VIP Premium is a one-time in-app purchase that unlocks unlimited plans, custom movements, friends, and extended history filters. What does VIP Premium unlock?

Last updated 12 August 2026 --- ## How to build a push / pull / legs split in Personal Trainer **URL:** https://mobile-squad.com/apps/personal-trainer/how-to-build-push-pull-legs-split/ **Last modified:** 2026-08-12 Personal Trainer Offline workout tracker, no subscription Google Play iOS coming soon Guide · 10 min · Updated 12 August 2026 · By Erwan Alliaume ### How to build a push / pull / legs split in Personal Trainer TL;DR. A 3-day push / pull / legs split is the most efficient hypertrophy template for intermediate lifters training 3–4 days a week. Build it in Personal Trainer in under 10 minutes: create a 3-day plan, add 4–5 movements per day, set rep ranges, and let the progressive-overload engine handle weight progression after each session. Deload every 4–6 weeks. #### What is push / pull / legs? Push / pull / legs (PPL) groups training days by movement pattern. Push covers chest, shoulders, and triceps. Pull covers back and biceps. Legs covers quads, hamstrings, glutes, and calves. Running PPL three times a week gives each muscle group 72+ hours of recovery, long enough to rebuild, short enough to keep frequency high. PPL works because the natural muscle pairings share warm-ups, share equipment, and don't overlap on recovery. It scales: 3 days a week is the maintenance dose; 6 days (PPL × 2) is the high-volume version for advanced lifters. #### Step-by-step setup - 1 Create a new training plan Open Personal Trainer, tap Plan → New plan . Choose a 3-day weekly split and name it Push / Pull / Legs . Pick days you can train consistently, Mon / Wed / Fri or Tue / Thu / Sat both work well. - 2 Build the Push day | Exercise | Sets | Reps | | Bench press | 4 | 5–8 | | Overhead press | 3 | 6–8 | | Incline dumbbell press | 3 | 8–12 | | Lateral raise | 3 | 10–15 | | Triceps pushdown | 3 | 10–15 | Rest 2 min on compounds, 60–90 s on isolation . Set in Personal Trainer's per-exercise rest timer. - 3 Build the Pull day | Exercise | Sets | Reps | | Deadlift or barbell row | 4 | 5–8 | | Pull-up or lat pulldown | 3 | 6–10 | | Seated cable row | 3 | 8–12 | | Face pull | 3 | 12–15 | | Barbell or EZ-bar curl | 3 | 8–12 | - 4 Build the Legs day | Exercise | Sets | Reps | | Back squat | 4 | 4–6 | | Romanian deadlift | 3 | 6–10 | | Leg press | 3 | 8–12 | | Leg curl | 3 | 10–15 | | Standing calf raise | 4 | 10–15 | - 5 Set body weight + plate increments In Profile , set your body weight and unit (kg or lbs). Personal Trainer's suggested-load engine uses bodyweight as a baseline for novice / intermediate / advanced multipliers, and rounds next-set targets to standard plate increments so the bar is always loadable. - 6 Log sets during training On each working set , log weight, reps, and a difficulty rating: Easy , Just right , Hard , or Failed . The rating drives the next-session suggestion, Easy bumps the load, Hard or Failed pulls it back. PRs are detected automatically. - 7 Review PRs and recovery every Sunday Personal Trainer pushes a Weekly Digest on Sunday at 19:00 local time. Open the dashboard, check the 72-hour recovery dial across all 15 tracked muscle groups, and inspect new PRs. If a group stays red for two weeks, swap the lift or reduce volume. - 8 Deload every 4–6 weeks Schedule a deload week every 4–6 weeks: keep the same lifts, drop working weight to ~60%, and cut volume by one third. Personal Trainer keeps the structure but the lighter inputs will recalibrate the suggested loads on the next cycle. Use it to clean up form and let connective tissue catch up. #### Common variations ##### PPL × 2 (6 days) Advanced lifters can run the split twice a week. Rotate heavy / light days to manage joint stress. ##### Upper-focus PPL Cap legs at one day, add a second push for lagging chest or shoulders. ##### Home-gym PPL Swap barbell rows for dumbbell rows, back squat for goblet squat or split squat, leg press for hip thrust. #### Related - Personal Trainer vs Strong app, feature comparison → - Personal Trainer FAQ, offline, sync, deload → - Personal Trainer for home-gym lifters → - Progressive overload volume calculator → #### Build your PPL split in 10 minutes.

Personal Trainer wins on offline-first usage, pay-once pricing, and friend leaderboard. Strong wins on iOS-first polish and a larger user base. TL;DR. Strong is the established set logger with a polished UI. Personal Trainer adds three things Strong doesn't: automatic progressive-overload suggestions based on per-set difficulty, a 72-hour muscle-group recovery dial across 15 groups, and a crew system with friend leaderboards and plan sharing.

Personal Trainer is local-first, offline by default, with optional encrypted cloud sync. The free tier is fully functional; VIP Premium is a one-time unlock for unlimited plans, custom movements, and crew sharing. No ads, no trackers, no subscription. Does Personal Trainer work offline? Yes, completely. The core workout loop, logging sets, building plans, history, charts, rest timer, runs entirely from local storage (AsyncStorage + Zustand). You can start a workout in airplane mode and finish it without ever touching the network. What is stored on the server? Only what you opt into. Sign-in identity (Google Sign-In → Firebase Auth) and any data you choose to back up to the optional encrypted cloud sync. Friend requests and shared plans flow through Firebase Cloud Functions. No analytics SDKs from ad networks, no data brokers. Is there a subscription? No. VIP Premium is a one-time in-app purchase. The free tier covers the full workout experience. What does VIP Premium unlock? Unlimited workout plans and custom movements, friend leaderboard and crew sharing, extended progress filters on charts, history, and the Muscle Museum, plus training-calendar history navigation. Receiving shared content is free. Does Personal Trainer suggest the next weight? Yes. After each set you tag a difficulty rating (Easy / Just right / Hard / Failed). The next-session suggestion is computed from that rating and rounded to standard plate increments. Easy bumps you up, Hard or Failed dials it back. How are plate increments calculated? Suggested loads round to standard plate jumps for your unit (kg or lbs). Typical: 2.5 kg / 5 lbs on compounds, 1 kg / 2.5 lbs on isolation . How does the 72-hour recovery dial work? After each set, the muscle targets attached to the movement are timestamped. The recovery dial fades each of the 15 tracked muscle groups from red (just trained) to green over 72 hours. Use it to spot overtraining and gaps. When should I deload? Every 4–6 weeks for most lifters, sooner if your recovery dial shows two consecutive weeks of red on the same group, or if difficulty ratings stay on Hard or Failed despite reduced loads. A deload is the same lifts at ~60% weight, one third less volume. Can I share plans and movements with friends? Yes. Add friends with a friend code, then share any plan or custom movement from its detail screen. Friends get a push notification even on a killed app, and can preview then copy to their library with one tap. What languages are supported? Six: English, French, Spanish, German, Italian, and Brazilian Portuguese. Auto-detects device language. Numbers, weights, dates follow locale conventions. Which platforms does it run on? Android and iOS. Built with React Native (Expo). Portrait-locked on iPad. No watchOS or Wear OS companion at this time. How are personal records detected? Any logged set that exceeds your previous best, by weight at the same rep target, by reps at the same weight, or by estimated 1RM , is flagged as a PR automatically. Can I migrate from Strong / Hevy / FitNotes? No automated importer yet. Recreate your most-used plan in Personal Trainer (under 10 minutes), log fresh sets going forward, keep your historical CSV from the other app as an archive. What happens if I uninstall? Local data is removed with the app. If you enabled cloud sync, your data persists on the server scoped to your Firebase Auth UID, and you can restore by reinstalling and signing in. How do I delete my account and data? Profile → Danger Zone → Delete account. Wipes cloud sync, friend graph, shared content. Local data is removed on uninstall. Are there ads or trackers? No. No ad SDKs, no analytics resold to third parties, no data brokers. Where can I report a bug or request a feature? Profile → Report a problem or suggest an improvement. Reports go straight to the studio. #### Related - How to build a push / pull / legs split → - Personal Trainer vs Strong app → - For home-gym lifters → - Personal Trainer vs Hevy → - Personal Trainer vs JEFIT → #### Ready to lift?

Home-gym lifters lose signal in basements and garages, run minimal equipment, and don't want a subscription. Personal Trainer is built for exactly that: full offline workout loop, swap any barbell movement for dumbbell or bodyweight equivalents in the exercise library, and progressive-overload suggestions that round to the plates you actually own. #### Why do home-gym lifters pick Personal Trainer? ##### Works in a basement with no signal Local-first storage means the app never blocks on a network round-trip. Plans, sets, timers, history, and charts all read from on-device storage. Cloud sync is opt-in and runs only when online. ##### Train with what you actually own The exercise library covers every major pattern in barbell, dumbbell, machine, cable, and bodyweight variants. Build a plan around your rack, your dumbbells, or just a pull-up bar. ##### Plate-aware load suggestions Next-set suggestions round to standard plate increments so the bar is always loadable. If you have micro-plates, just log the actual weight, the engine adapts to your inputs. ##### No subscription Free tier covers the full workout experience. VIP Premium is a one-time unlock for unlimited custom movements (handy when you've improvised six dumbbell variations), crew sharing, and extended filters. #### Sample home-gym push / pull / legs Built around a typical home-gym kit: barbell + adjustable bench + dumbbells. No machines, no cables. ##### Push - Bench press, 4×5–8 - Dumbbell overhead press, 3×6–10 - Incline dumbbell press, 3×8–12 - Lateral raise, 3×10–15 - Close-grip dumbbell press, 3×8–12 ##### Pull - Barbell row, 4×6–10 - Pull-up or chin-up, 3×AMRAP - Dumbbell row, 3×8–12 - Face pull with band, 3×12–15 - Barbell or dumbbell curl, 3×8–12 ##### Legs - Back squat, 4×4–6 - Romanian deadlift, 3×6–10 - Bulgarian split squat, 3×8–12 / side - Dumbbell hip thrust, 3×8–12 - Standing calf raise, 4×10–15 Recreate this plan in Personal Trainer in under 10 minutes.

Yes. The full workout loop runs offline from on-device storage. You only need a network when you choose to back up to the optional encrypted cloud sync. Can I track dumbbell-only routines? Yes. The exercise library covers dumbbell variants of every major pattern. Build a plan from dumbbell movements only, and progressive overload still works on dumbbells in whatever increment your set jumps in. How does it handle non-standard plate increments? Suggested loads round to standard plate jumps. If you own micro-plates, just enter the actual loaded weight, the engine adapts to your inputs over time. #### Related - How to build a push / pull / legs split → - Personal Trainer vs Strong app → - FAQ → - Film form checks with ReplayR → - Progressive overload volume calculator → #### Built for the gym in your garage.

The calculator aggregates your weekly volume and charts whether it's trending up, the clearest signal that progressive overload is happening. Short answer. Training volume is sets times reps times weight, and a week-over-week rise in that number for a muscle group is the mechanical proof that progressive overload is happening. This free tool aggregates volume per muscle group, charts the trend, and stores the history in your browser. Training volume is defined as Sets × Reps × Weight . A week-over-week increase in that number for a given muscle group is the mechanical proof of progressive overload. This free tool tracks it, stores data locally in your browser, and visualises the trend. No account required. Want automated tracking on your phone?

Get it on Google Play #### What is progressive overload volume? Progressive overload is the foundational principle of resistance training: for a muscle to grow and get stronger, it must be subjected to greater mechanical stress over time. Volume, the product of Sets × Reps × Weight, is the single most important metric for tracking whether that stress is increasing. ##### The volume equation If you did 3 sets of 8 reps at 80 kg on bench press, your chest volume for that exercise is 3 × 8 × 80 = 1,920 kg . Add all chest exercises in a session and you get weekly chest volume. Tracking this number week over week is how you verify progressive overload, not just guess at it. ##### Why sets alone aren't enough Counting sets is a useful proxy but misses weight progression. You could do 15 sets of bench at 60 kg and 12 sets at 100 kg in the same week, 15 sets looks like more volume but 12 × 100 kg = 37% more mechanical work. Total volume captures both dimensions simultaneously. ##### Volume vs. intensity Intensity (% of 1-rep max) determines which muscle fibres you recruit and how much neural demand you place on the lift. Volume determines how much total work those fibres do. Both matter. Progressive overload means increasing either: adding weight (intensity) or adding reps/sets (volume). This calculator captures both in one number. ##### Compounding effect over a block A linear progression of 5% additional volume per week sounds small. Over 8 weeks that's a 47% increase in total work. The chart in this tool makes that trend visible. If your line isn't going up, something in your programming, frequency, weight selection, or consistency, needs adjusting. #### Evidence-based weekly volume targets These estimates are derived from the Volume Landmarks framework developed by Dr. Mike Israetel and colleagues at Renaissance Periodization. They represent ranges for natural, drug-free lifters at intermediate to advanced levels. Beginners should start at the lower end. Advanced lifters may tolerate the upper end during a volume accumulation block. | Muscle group | MEV (sets/wk) | MAV (sets/wk) | MRV (sets/wk) | | Chest | 8–10 | 12–20 | 22+ | | Back (Upper) | 10–12 | 14–22 | 25+ | | Shoulders | 8–16 | 16–22 | 26+ | | Biceps | 8–14 | 14–20 | 26+ | | Triceps | 6–10 | 10–18 | 22+ | | Quads | 8–12 | 12–18 | 20+ | | Hamstrings | 6–10 | 10–16 | 20+ | | Glutes | 4–8 | 8–16 | 20+ | | Calves | 8–12 | 12–16 | 20+ | | Abs | 10–16 | 16–20 | 25+ | MEV = Minimum Effective Volume. MAV = Maximum Adaptive Volume. MRV = Maximum Recoverable Volume. Source: Renaissance Periodization (Israetel et al.). These are set-count estimates; the volume calculator above tracks total tonnage, which is a more granular metric. #### How to use the volume calculator The tool above requires three inputs per exercise: a date, the muscle group being trained, and the sets you performed. Here's how to get the most out of it. Step 1: Log each exercise after your session Open the calculator immediately after training (or the same evening). Enter today's date, the exercise name, the muscle group it primarily targets, and each set's reps and weight. You don't need to be precise about secondary movers, assign each exercise to its primary muscle group. A compound like bench press goes to Chest even though it also works Triceps and Shoulders. Step 2: Review the weekly chart After a few sessions the chart will populate with weekly bars. Use the muscle-group filter to isolate one group at a time. You want to see each bar taller than the last. If a muscle group shows the same volume three weeks in a row you've hit a plateau, it's time to add a set, increase the working weight, or both. Step 3: Plan a deload when volume peaks Volume cannot increase forever. After 4–8 weeks of accumulation, when performance starts to stall or joint fatigue builds, schedule a deload week: reduce volume to 50% of your peak. After the deload, resume from the pre-deload level. You'll notice you can push further in the next block. The chart makes deload timing obvious: the drop is deliberate, not a failure. Step 4: Use Personal Trainer for automated tracking This web calculator is a quick reference tool. For automated volume tracking, progressive-overload suggestions, rest timers, and a full exercise library on your phone, the Personal Trainer app handles all of this natively, including offline use. You log sets on your phone during the session and the app shows volume trends per muscle group in its built-in charts. #### Progressive overload methods beyond volume Volume is the most measurable indicator, but progressive overload has several valid mechanisms. Using more than one concurrently produces faster adaptation, and the calculator implicitly tracks most of them, since weight increases show up in the volume total. ##### Load progression Add weight to the bar while keeping reps constant. The most direct form of progressive overload and the easiest to measure. Aim for 2.5–5 kg jumps on compounds, 1–2.5 kg on isolations, when you've hit the top of your rep range for all sets. ##### Rep progression Keep weight constant, add one rep per set each week. Once you reach the top of your target rep range (e.g. 12 reps), add weight and drop back to the bottom (e.g. 8 reps). This "double progression" method is highly effective for intermediate lifters. ##### Set progression Add one working set per week across a training block. Starting at 10 weekly sets for chest and adding one set per week reaches 16 sets by week 7, a 60% volume increase without touching the weight. Used in most intermediate hypertrophy programs. ##### Frequency progression Train each muscle group more times per week. Moving chest from once to twice weekly, while keeping per-session volume the same, nearly doubles the protein synthesis stimulus without requiring more intensity per session. The weekly volume total increases proportionally. ##### Range of motion Using a fuller range of motion under load, for example, a deep Romanian deadlift vs. a partial one, increases the mechanical tension on the muscle through its stretched position. Research suggests stretched-position loading may be particularly effective for hypertrophy. ##### Density progression Perform the same total volume in less time by shortening rest intervals. This is a form of metabolic overload rather than mechanical overload, and is most useful in phases oriented toward work capacity or when absolute load is temporarily limited (travel, equipment constraints). #### Common volume-tracking mistakes Most lifters who feel they're training hard but not progressing are making one of these errors. The volume chart usually makes them obvious. ##### Inconsistent effort across sets If you log 4 sets of 10 at 80 kg but your first two sets are close to failure and your last two are well below it, the volume number looks the same but the stimulus isn't. Effective reps, those within 3–4 reps of failure, matter more than total reps. Stay close to failure consistently. ##### Junk volume accumulation Adding sets in the 50–60% 1RM range adds volume on paper but provides little stimulus. This is "junk volume", it fatigues you without driving adaptation. Keep working sets at or above the minimum effective intensity (~65–70% 1RM or within 6 reps of failure for hypertrophy). ##### Ignoring inter-session recovery More volume is not always better. If you're training a muscle group three times per week at high volume but aren't recovering between sessions, soreness persists, performance drops, you've exceeded your MRV. The chart shows high absolute volume but your performance log shows a plateau. Cut frequency or per-session sets. ##### No deload strategy Accumulating volume indefinitely without deloading leads to systemic fatigue masking fitness. Lifters who deload every 4–8 weeks consistently outperform those who train through fatigue. After a deload, returned-to-baseline performance often exceeds pre-deload peak, this is called supercompensation. #### FAQ What is training volume and why does it matter? Training volume is the total mechanical work performed: Sets × Reps × Weight. It matters because progressive overload, the primary driver of muscle growth and strength gains, is most reliably tracked through volume. If your weekly volume per muscle group increases over a training block, you're applying a progressively larger stimulus. If it stagnates, adaptation stalls. How much weekly volume should I aim for per muscle group? Evidence-based estimates suggest 10–20 sets per week for most intermediate lifters, with Minimum Effective Volume at around 8–10 sets and Maximum Recoverable Volume at 20–30+ sets for large muscle groups. However, set count is a proxy. Total tonnage (kg or lbs) captures both sets/reps and weight progression, making it a more complete metric. Is my data saved when I close the browser? Yes. The calculator uses your browser's localStorage to persist all logged exercises. Your data survives browser restarts, tab closes, and page refreshes. It is stored only on your device, nothing is sent to a server. To erase data, use the "Reset all" button or clear localStorage in your browser developer tools. Should I track compound lifts to multiple muscle groups? For simplicity, assign each exercise to its primary mover. Log bench press to Chest, not Chest + Triceps + Shoulders. This avoids double-counting and keeps the chart readable. If you perform an exercise specifically targeting a secondary mover (e.g. close-grip bench as a dedicated triceps exercise), log it to Triceps instead. When should I deload based on the chart? Schedule a deload week after 4–8 weeks of accumulation, or when: (1) performance stalls or regresses despite consistent effort; (2) soreness is persistent and doesn't resolve between sessions; (3) motivation drops significantly. A deload cuts volume to ~50% while maintaining intensity. After the deload, volume typically rebounds above pre-deload levels. Can I use this calculator on mobile? Yes, the calculator is fully responsive. However, for in-gym tracking we recommend the Personal Trainer app (Android), which handles set logging natively, works fully offline, and shows built-in volume charts per muscle group with automatic progressive-overload suggestions, all without needing to open a browser during your session. #### Related - How to build a push / pull / legs split → - Personal Trainer for home-gym lifters → - Personal Trainer vs Strong app → - Personal Trainer FAQ → #### Track volume automatically in the app. Personal Trainer logs your sets, calculates volume per muscle group, and suggests next-session loads, all offline, no subscription.

Get your estimated 1RM from four validated formulas, plus an instant percentage chart showing the load for every training zone. Short answer. This free calculator estimates a one-rep max from any weight and rep count using the Epley, Brzycki, Lander and O'Conner formulas, then prints the percentage chart for every training zone: above 85 percent for strength, 65 to 85 for hypertrophy , below 65 for endurance. Your one-rep max (1RM) is the theoretical maximum weight you can lift for a single repetition with proper form. Knowing it lets you prescribe training loads by percentage, 85%+ for strength, 65–85% for hypertrophy, below 65% for muscular endurance .

Get it on Google Play #### What is a 1-rep max and why does it matter? Your one-rep max (1RM) is the maximum load you can lift for a single complete repetition of an exercise with correct form. It is the foundational reference point for percentage-based strength programming. By expressing every training load as a percentage of your 1RM, you can precisely target specific neuromuscular adaptations, strength, hypertrophy, or muscular endurance, regardless of the absolute weight on the bar. ##### Why not just test your 1RM directly? A true 1RM test requires significant neural activation, careful warm-up, and ideally a spotter. Testing too frequently accumulates fatigue and injury risk. Estimated 1RMs from submaximal sets (3–6 reps at near-failure) are sufficiently accurate for programming purposes and are safer to perform regularly. Most powerlifters formally test 1RM only at competitions or at the end of a training cycle. ##### The percentage-based training system Once you have an estimated 1RM, every training load becomes a fraction of that number. A 5×5 at 80% 1RM means the same relative effort for a 60 kg lifter as for a 200 kg lifter, the absolute weights differ but the physiological demand is equivalent. This makes percentage-based programming transferable, comparable, and scalable across all experience levels. ##### How formulas differ at high rep counts At 1–5 reps, all four formulas produce nearly identical results (within 1–2%). The divergence grows above 8 reps because the load-to-repetition relationship is not perfectly linear, slow-twitch fibre recruitment increases, fatigue curves differ between individuals, and rep quality degrades. For sets of 10+ reps, use the average of all four formulas and treat the result as a conservative estimate. ##### 1RM vs. training max Many programs (5/3/1, Texas Method) prescribe percentages off a "training max" set at 90% of your estimated 1RM. This creates a conservative baseline that leaves room for daily variation in strength, reduces injury risk, and ensures you can always hit prescribed reps. When a cycle completes, you increase the training max by 2.5–5 kg and repeat, a sustainable linear progression . #### The four 1RM formulas compared Each formula was derived from different populations and validation methodologies. Understanding what each one measures helps you choose which result to weight most heavily for your training context. | Formula | Equation | Best for | Rep range accuracy | | Epley (1985) | w × (1 + r/30) | General use, most cited | 1–10 reps | | Brzycki (1993) | w × (36 / (37 − r)) | Lower rep ranges, powerlifting | 1–8 reps | | Lander (1985) | w / (1.013 − 0.0267123 × r) | Higher rep ranges | 5–12 reps | | O'Conner (1989) | w × (1 + 0.025 × r) | Conservative estimate | 1–15 reps | Where w = weight lifted, r = reps performed. Sources: Epley BF (1985); Brzycki M (1993); Lander J (1985); O'Conner B et al. (1989). #### Training zones and their percentage ranges The percentage chart generated by this tool maps directly to three primary training zones. Each zone recruits different muscle fibre types, produces different hormonal and neural adaptations, and requires different recovery protocols. Strength Zone 85–100% 1RM · 1–5 reps Heavy loading in this zone maximises neural adaptations, motor unit synchronisation, rate coding, and intermuscular coordination. Myofibrillar hypertrophy (increasing contractile protein density) also occurs, but the primary adaptation is increased force production per motor unit. Strength zone training requires longer rest intervals (3–5 minutes) and higher intra-workout recovery. This is the domain of powerlifting and Olympic weightlifting protocols. Hypertrophy Zone 65–85% 1RM · 6–15 reps This range produces a high degree of metabolic stress and mechanical tension simultaneously, the two primary hypertrophy drivers identified in the literature (Schoenfeld, 2010). Moderate loads allow sufficient volume per set to accumulate total tonnage while staying close enough to failure to recruit high-threshold motor units. Rest intervals of 60–120 seconds increase metabolic stress; 2–3 minutes allow more volume per session. Most bodybuilding programs operate in this zone. Endurance Zone <65% 1RM · 15+ reps Low-load, high-rep training primarily develops slow-twitch fibre oxidative capacity and local muscular endurance. It is less effective for maximum strength or hypertrophy unless sets are taken very close to or to failure, in which case even 30% 1RM loads can produce significant hypertrophy (Morton et al., 2016). This zone is used for warm-up sets, deload weeks, rehabilitation, and athletes in endurance sports needing muscular durability rather than maximum strength. #### How to use the 1RM calculator Step 1: Choose a submaximal set performed to near-failure Pick a recent set where you reached or came within 1–2 reps of failure. Sets of 3–6 reps are ideal. Avoid using warm-up sets or sets where you stopped well short of failure, the formulas require near-maximal effort to be accurate. If you have multiple qualifying sets, use the heaviest one. Step 2: Enter weight and reps above Type the weight you lifted and the number of reps you completed. The calculator updates in real time. Switch between kg and lbs using the unit toggle, your inputs are converted automatically when you switch. The four formula results and their average appear immediately. Step 3: Read the percentage chart Scroll down to the generated table. Each row shows the weight you should lift at that percentage of your estimated 1RM, along with an approximate rep range to failure. Use this to plan your next session: if your program calls for 4×6 at 80%, find the 80% row and load that weight on the bar. Step 4: Re-estimate every 4–6 weeks Your 1RM changes as you get stronger. Re-run this calculator after each training cycle using your latest working-weight performance. Percentage-based programs rely on accurate 1RM data, an underestimated 1RM results in training too light; an overestimated one produces sets you can't complete. For automated 1RM tracking across every lift and session, use the Personal Trainer app, which calculates estimated 1RM from each logged set. #### Common 1RM estimation mistakes ##### Using reps that weren't near failure If you stopped at 8 reps when you had 4 more in the tank, the formula will drastically underestimate your 1RM. Always use sets taken to or within 1–2 reps of true failure. This is called reps-in-reserve (RIR), aim for RIR 0–2 when measuring for 1RM estimation. ##### Using sets of more than 10 reps Above 10 reps, formula accuracy drops significantly. A set of 20 reps to failure will produce 1RM estimates that are 10–20% off. Use a heavier weight for fewer reps whenever you plan to estimate your 1RM for programming purposes. ##### Confusing estimated 1RM with actual 1RM The estimate assumes all effort was identical and form was consistent. Fatigue from a long session, poor warm-up, or high psychological arousal can shift the estimate ±5%. Treat the output as a planning number, not a definitive maximum. If programming prescribes 95%+ loads, test your actual 1RM first. ##### Never updating the estimate A 1RM estimate from 6 months ago is stale. Strength adapts quickly, most intermediate lifters gain 5–15% on major lifts over a 12-week block. Using old percentages means training at incorrect intensities. Re-estimate at the start of each new training block, or whenever your top-set performance changes significantly. #### FAQ Which formula is most accurate? No single formula is universally best. Epley and Brzycki are most accurate for 1–8 reps; Lander and O'Conner perform better above 8 reps. The average of all four is the safest estimate for programming. For maximum accuracy, formally test your actual 1RM every 8–12 weeks in a fresh session with a spotter. Can I use this for any exercise? Yes, the formulas are lift-agnostic. They work for squat, bench, deadlift, overhead press, weighted pull-ups, and most compound movements. They are less reliable for isolation exercises (curls, lateral raises) because form breakdown under fatigue makes the true rep ceiling unpredictable. Is my data saved? Yes. Your last inputs (weight, reps, unit) are saved in your browser's localStorage. They persist across page reloads and browser restarts. Nothing is sent to a server. Use the Reset button to clear the stored values. What is a training max and should I use it? A training max is 90% of your estimated 1RM. Programs like Jim Wendler's 5/3/1 prescribe all working percentages off the training max rather than the true 1RM. This builds in a fatigue buffer and means you can always complete the prescribed sets even on a suboptimal day. If a program says to use a training max, multiply your estimated 1RM by 0.9 and use that as your baseline. How often should I re-estimate my 1RM? Re-estimate at the start of each new training block (typically every 4–8 weeks). Novice lifters should re-estimate more frequently, strength gains are rapid early and old estimates become stale within 2–3 weeks. Intermediate and advanced lifters can re-estimate every 4–6 weeks. Any time your top-set performance shows a clear improvement, update the estimate. #### Related - Progressive overload volume calculator → - Ideal rest interval calculator → - How to build a push / pull / legs split → - Personal Trainer FAQ → - Personal Trainer vs Hevy → #### Track your 1RM automatically in the app. Personal Trainer estimates your 1RM from every logged set, suggests percentage-based loads for the next session, and tracks your strength over time, all offline, one-time purchase.

Get the evidence-based rest interval recommendation, then start the built-in countdown timer for your next set. Short answer. Rest interval is the most under-programmed variable in lifting. The evidence is consistent: 3 to 5 minutes for strength work, 1 to 3 minutes for hypertrophy , under a minute for endurance. This free tool gives the recommendation for your goal and runs the countdown between sets. Rest interval length is one of the most under-programmed variables in resistance training. Too short and you compromise subsequent set quality; too long and you lose metabolic adaptations. Research consistently shows strength work needs 3–5 minutes, hypertrophy 90 seconds to 3 minutes, and endurance circuits 30–60 seconds . This calculator gives you the right number for your goal and lets you time it in the gym. Want a rest timer that starts automatically after each set? Personal Trainer starts the rest countdown the moment you log a set, fully offline.

Automatic rest timers, on your phone, offline Personal Trainer starts the countdown the instant you log a set and buzzes your phone when rest is over, no Wi-Fi, no subscription. Get it on Google Play #### Why do rest intervals matter? Rest between sets is not downtime, it is an active recovery phase that determines how much physiological capacity you bring to the next set. The length of that window controls phosphocreatine resynthesis, lactate clearance, neural recovery, and the accumulated hormonal environment of the session. Getting it wrong in either direction compromises training quality and long-term adaptation. ##### Phosphocreatine and the energy system Maximum-effort contractions lasting under 10 seconds, a heavy set of 1–5 reps, primarily draw energy from the phosphocreatine (PCr) system. PCr stores are depleted within seconds and take 3–5 minutes to fully replenish. Training with insufficient rest means each subsequent heavy set begins with a partially depleted PCr pool, reducing the maximum force you can produce and compromising the quality of neural adaptation. ##### The 2016 Schoenfeld study on rest and hypertrophy A landmark randomised controlled trial (Schoenfeld BJ et al., 2016) compared 1-minute vs. 3-minute rest intervals over 8 weeks in resistance-trained men. The 3-minute group produced significantly greater gains in muscle thickness (biceps, triceps) and strength (squat, bench press). The conclusion: longer rest preserves volume quality across sets, which is the primary driver of hypertrophy. Short rest may feel more productive but compromises actual work output. ##### Metabolic stress and the short-rest argument Short rest intervals (45–90 seconds) increase metabolic byproduct accumulation, lactate, hydrogen ions, and the associated "pump" and hormonal response. The older bodybuilding tradition prescribed short rest for this reason, believing the acute hormone spike drove muscle growth. Current research does not support this mechanism as a primary driver of hypertrophy. The metabolic stress is real but the anabolic signal is secondary to mechanical tension and volume. ##### Supersets and antagonist pairs Pairing two non-competing exercises (e.g. bench press + seated row) during what would otherwise be rest allows the agonist to recover while the antagonist works. Research shows antagonist supersets maintain strength output on subsequent sets better than agonist supersets (Robbins et al., 2010). They increase session density and volume per unit time without compromising performance, an efficiency gain with no physiological downside. #### Evidence-based rest interval reference | Training goal | Intensity (% 1RM) | Rep range | Rest interval | Primary mechanism | | Max Strength | 90–100% | 1–3 | 4–5 min | PCr resynthesis, neural recovery | | Strength | 80–90% | 3–5 | 3–5 min | PCr resynthesis | | Hypertrophy | 65–85% | 6–12 | 90 s – 3 min | Volume preservation, tension | | Hypertrophy (pumping) | 60–75% | 12–15 | 60–90 s | Metabolic stress, pump | | Muscular endurance | 50–65% | 15–20 | 30–60 s | Oxidative capacity, lactate tolerance | | Circuit training | Sources: Schoenfeld BJ et al. (2016) J Strength Cond Res. NSCA Essentials of Strength Training & Conditioning (4th ed.). de Salles BF et al. (2009) Sports Med. #### How to use the rest interval calculator Step 1: Select your training goal Choose Strength if you're working at 85%+ of your 1RM for 1–5 reps. Choose Hypertrophy if you're in the 65–85% range for 6–15 reps. Choose Endurance for circuit training, metabolic conditioning, or sets of 15+. If you're doing multiple goals in one session (strength work first, then hypertrophy), change the setting between blocks. Step 2: Select exercise type and experience level Compound movements recruit more muscle mass and generate more systemic fatigue, they need more rest. Isolation exercises are less taxing and can use shorter intervals. Advanced lifters who consistently train close to failure need slightly longer rest than beginners because the intensity of their effort per set is higher. Step 3: Start the timer after your set Hit one of the timer buttons as soon as you rack the bar. The circular progress ring counts down in real time. The minimum button starts a timer at the lower end of the recommended range (suitable if you're short on time or training at lower intensities within the goal range). The maximum button uses the upper end. For hypertrophy, starting with the midpoint is practical for most sessions. Step 4: Use Personal Trainer for automatic rest timers in the gym Opening a browser between sets is awkward. The Personal Trainer app starts the countdown the moment you log a completed set, vibrates when rest is over, and remembers your preferred rest time per exercise, all without internet. This tool is a reference; the app handles in-session timing natively. #### Factors that modify rest requirements ##### Session position Early sets in a session typically need less rest because fatigue is lower. Sets towards the end of a workout, when glycogen depletion and systemic fatigue accumulate, often need 15–30 extra seconds compared to the same exercise at the start. Feel free to extend rest in the later portion of a session, especially for heavy compounds. ##### Sleep and recovery quality Sleep debt reduces both CNS function and PCr resynthesis rate. On poor-sleep days, conservative rest intervals (top of the recommended range) protect training quality better than pushing standard intervals. A well-recovered lifter will restore performance faster than the same lifter after a poor night's sleep. ##### Nutritional state Training in a fasted state or on a caloric deficit increases perceived fatigue and may slow ATP regeneration. Extending rest by 20–30% during deficit phases is a practical adaptation that preserves volume quality when energy availability is compromised. ##### Altitude and temperature Training at altitude (above 1,500m) or in hot environments increases cardiovascular demand and accelerates fatigue. Both conditions typically require 10–30% more rest per set to maintain equivalent performance. Hydration status interacts strongly with temperature, dehydration above 2% of body mass significantly impairs strength output. #### FAQ How long should I rest between sets for muscle growth? The evidence-based recommendation is 90 seconds to 3 minutes for hypertrophy. A 2016 RCT by Schoenfeld et al. found 3-minute rest intervals produced more muscle and strength gains than 1-minute rest over 8 weeks. The practical optimum for most lifters is 2–3 minutes for compound lifts and 90 seconds for isolation work. Does resting longer slow down my workout too much? Longer rest does increase session duration, but it also increases quality per set. A 1-hour session with 2-minute rests will contain fewer total sets than 90-second rest, but each set will be performed with better form and closer to your performance ceiling. If time is limited, use antagonist supersets (e.g. bench + row) rather than shortening rest, you get the same time benefit without compromising set quality. Should I use a fixed rest period or train by feel? Fixed rest periods are more reproducible and produce more consistent training stimuli, making them better for tracking progressive overload . Training by feel introduces variability, you may rest 5 minutes because a set felt hard but was actually fine, or rush the next set when fatigued. Use a timer for your working sets, especially on heavy compounds. You can adjust by feel for isolation accessories. Is it OK to rest longer if a set was very hard? Yes. The recommended ranges are guidelines, not limits. If a set was taken to true failure or form was breaking down, extending rest by 30–60 seconds is appropriate. Rigid adherence to short rest when you need more recovery produces worse subsequent sets and increases injury risk. The goal is quality reps, and rest is the mechanism that protects quality. #### Related - 1-Rep Max calculator → - Progressive overload volume calculator → - How to build a push / pull / legs split → - Personal Trainer FAQ → #### Automatic rest timers in the app. Personal Trainer starts the rest countdown the moment you log a set and vibrates when it's time to go, all offline, one-time purchase.

Get the exact plates to load on each side of the bar, with a visual barbell diagram. Supports kg and lbs with full plate sets. Short answer. This free calculator turns a target weight into the exact plates to load per side, using a greedy largest-first fill so you handle the fewest plates possible. It supports kg and lbs with full plate sets and draws the loaded bar so the arrangement can be checked at a glance. Loading a barbell correctly is faster and safer when you know the exact combination before you approach the rack. This calculator uses a greedy algorithm, largest plates first, smallest last , to find the minimum number of plates that reach your target. The visual guide shows you the loaded bar so you can verify at a glance. Want plate loading calculated automatically during your session? Personal Trainer shows plate loading for every planned set, fully offline. Get on Google Play #### Calculate plates per side Unit: kg Target total weight ( kg ) Bar weight ( kg ) 20 kg, Olympic men's bar 15 kg, Olympic women's bar 10 kg, EZ curl bar 25 kg, Safety squat / trap bar 0 kg, custom / no bar Available plates Full set (25/20/15/10/5/2.5/1.25 kg) Standard (20/10/5/2.5/1.25 kg) Basic (20/10/5/2.5 kg) Total weight loaded — kg Plates per side — Closest achievable (difference) — Visual barbell (one side shown) Load plates from largest (closest to collar) to smallest (outermost). | Plate size | Qty per side | Weight contribution (both sides) | Enter a target weight above to see the plate breakdown.

Get it on Google Play #### How do you load a barbell correctly? Loading a barbell seems trivial but poor technique wastes time, increases injury risk (from uneven loading or unsecured plates), and complicates warm-up progressions. Understanding the plate system lets you load any weight quickly and safely. ##### Load large plates first, small plates last This is the standard convention. Load the heaviest plates closest to the sleeve collar (innermost position), then work outward to progressively smaller plates. This centres the weight distribution close to the sleeve hub, which reduces sleeve flex and keeps the bar balanced. A 20 kg plate loaded outside a 2.5 kg plate on the same side creates an unstable cantilever that stresses the sleeve joint. ##### Always use collars for safety Spring collars or Olympic collars prevent plates from sliding off during a set. On heavy deadlifts and squats especially, the bar flexes under load, plates can shift outward and fall off without collars. A falling 20 kg plate from squat height generates enough force to cause serious injury. Collar use is non-negotiable on Olympic lifts and any barbell exercise performed away from the floor. ##### Why the 20 kg bar is the standard The IPF (International Powerlifting Federation) and IWF (International Weightlifting Federation) both use a 20 kg men's bar as standard. This weight became universal because it is heavy enough to provide meaningful resistance for most compound lifts as a bare bar warm-up, yet light enough to be manipulated safely by most trained athletes. Women's barbells weigh 15 kg and have a narrower diameter (25 mm vs. 28–32 mm for men's bars). ##### Fractional plates for percentage-based programming Percentage-based programs often prescribe weights that can't be achieved with standard plate sets. If your 1RM squat is 145 kg and a session calls for 82.5%, that's 119.6 kg, not achievable with 2.5 kg as the smallest plate (nearest is 120 kg). Fractional plates (0.5 kg / 0.25 kg) close this gap and are particularly useful for overhead press and bench press where even 2.5 kg increments can be large relative to the load. #### Standard plate weights reference | Metric plate | Diameter (approx.) | Standard colour (IWF) | | 25 kg | 450 mm | Red | | 20 kg | 450 mm | Blue | | 15 kg | 450 mm | Yellow | | 10 kg | 400 mm | Green | | 5 kg | 310 mm | White | | 2.5 kg | 240 mm | Black | | 1.25 kg | 200 mm | Chrome / Grey | | Imperial plate | Equivalent (approx.) | Typical use | | 45 lbs | ~20.4 kg | Main load plate (powerlifting) | | 35 lbs | ~15.9 kg | Intermediate loading | | 25 lbs | ~11.3 kg | Warm-up / accessories | | 10 lbs | ~4.5 kg | Micro-progression | | 5 lbs | ~2.3 kg | Fine adjustment | | 2.5 lbs | ~1.1 kg | Fractional loading | IWF = International Weightlifting Federation. Colour coding may vary between manufacturers, the IWF standard applies to competition plates, not all gym plates. #### How to use the plate calculator Step 1: Enter your target weight Type the total weight you want on the bar, including the bar itself. If your program says "bench 80 kg" and the bar weighs 20 kg, enter 80, the calculator will deduct the bar weight automatically. Switch to lbs if your gym uses imperial plates. Step 2: Select bar weight and available plates Choose the bar you're using from the dropdown. Select which plate sizes your gym has, most commercial gyms have the "standard" or "full" set. If your gym only stocks 20, 10, 5, and 2.5 kg plates, choose "basic" to avoid the calculator suggesting plates you don't have. Step 3: Read the visual guide and plate list The barbell diagram shows the plate order from the collar outward on one side. The table below confirms the exact count. Load plates from the diagram's leftmost position (collar) outward, largest first. Match the plate count on both sides before collaring. Step 4: Track your weights in the app For session-by-session plate loading suggestions based on your progressive overload targets, the Personal Trainer app generates the plate configuration for every planned set automatically, so you walk up to the rack already knowing what to load, without opening a browser. #### FAQ How do I calculate plates for a barbell? Subtract the bar weight from your target total, divide by 2 to get weight per side, then use the largest plates available to fill that weight. For example: target 100 kg, bar 20 kg → 80 kg total plates → 40 kg per side → two 20 kg plates per side. This calculator does the arithmetic for you and handles odd weights by finding the nearest achievable combination. How much does a standard barbell weigh? A standard Olympic men's barbell weighs 20 kg (44 lbs). Women's Olympic barbells weigh 15 kg (33 lbs). EZ curl bars are typically 10 kg. Trap/hex bars and safety squat bars vary but are usually 25–30 kg. Always verify the bar weight at your gym, not all bars match specifications, and worn bars can be lighter. What if the target weight isn't achievable with my plates? The calculator finds the closest achievable weight at or below your target and shows the shortfall. To reach exact odd weights, you need fractional plates (0.5 kg / 0.25 kg or 1.25 lbs). These are available from specialty strength equipment retailers and are particularly useful for overhead press and bench where small increments matter. Do I need to include collar weight? Standard spring collars weigh approximately 0.5 kg each (1 kg total for both). For casual training this is negligible. For competition or precise percentage-based programming, weigh your collars and add them to your bar weight input to get an accurate total. Some competition-grade collar clamps weigh 2.5 kg each. #### Related - 1-Rep Max calculator → - Progressive overload volume calculator → - Personal Trainer for home-gym lifters → - Personal Trainer FAQ → - Personal Trainer vs JEFIT → #### See plate loading for every set in the app. Personal Trainer shows the exact plate configuration for each planned weight in your session, all offline, one-time purchase.

Pair it with your macro targets for complete training + nutrition control. Get it on Google Play #### What is TDEE and why does it matter for training? Total Daily Energy Expenditure is the total number of calories your body uses over 24 hours. It is the single most important number for nutrition planning because it determines whether your body is in an energy surplus (gains mass), deficit (loses mass), or equilibrium (maintains mass). Every nutrition goal, muscle gain, fat loss, or body recomposition, starts with an accurate TDEE estimate. ##### The four components of TDEE TDEE comprises: (1) Basal Metabolic Rate (BMR), the energy your body uses at complete rest, typically 60–70% of TDEE; (2) Thermic Effect of Food (TEF), the energy cost of digesting and absorbing food, roughly 10% of total calories; (3) Non-Exercise Activity Thermogenesis (NEAT), all movement that isn't structured exercise (fidgeting, walking, standing); (4) Exercise Activity Thermogenesis (EAT), your gym sessions and sport. The activity factor in this calculator approximates the combined contribution of NEAT and EAT. ##### The Mifflin-St Jeor equation This calculator uses the Mifflin-St Jeor equation, published in 1990, which has been validated as the most accurate BMR formula for most adult populations (Frankenfield et al., 2005). For males: BMR = (10 × weight in kg) + (6.25 × height in cm) − (5 × age) + 5. For females: same formula minus 161 instead of +5. The result is multiplied by an activity factor ranging from 1.2 (sedentary) to 1.9 (extremely active) to produce TDEE. ##### Why TDEE estimates vary, and how to calibrate Formulas estimate TDEE with approximately ±10–15% accuracy. Factors that cause individuals to deviate: body composition (muscle burns more than fat at rest), metabolic adaptation (chronic dieting reduces TDEE), gut microbiome differences, and hormonal status. The most accurate method to find your true TDEE: track calories and body weight daily for 2–3 weeks at a stable eating pattern. If weight is stable, that calorie intake is your TDEE. ##### Protein: the non-negotiable macro Protein is the only macronutrient that directly provides amino acids for muscle protein synthesis. It also has the highest thermic effect (25–30% of calories consumed are spent digesting it), making high-protein diets metabolically advantageous during a cut. The ISSN (2017) Position Stand recommends 1.4–2.0 g/kg for active individuals seeking body composition improvements, with higher intakes (up to 3.1 g/kg) showing no adverse effects in healthy adults. #### Activity level multipliers explained | Level | Multiplier | Who it fits | Weekly training | | Sedentary | × 1.2 | Desk job, no structured exercise | 0 days | | Lightly active | × 1.375 | Light exercise, standing job | 1–3 days | | Moderately active | × 1.55 | Regular gym sessions, active lifestyle | 3–5 days | | Very active | × 1.725 | Hard training, sport athlete | 6–7 days | | Extremely active | × 1.9 | Physical job + twice-daily training | Daily + job | Most recreational gym-goers 3–5 days/week fit the "moderately active" category. When in doubt, choose the lower multiplier and adjust based on weekly weight trend data. #### Macronutrient targets by goal ##### Muscle gain (lean bulk) Target calories: TDEE + 200–500 kcal. Protein: 1.8–2.2 g/kg. Fat: 25–30% of total calories. Carbohydrates: remainder. The caloric surplus fuels muscle protein synthesis and provides glycogen for training intensity. Larger surpluses (700+ kcal) do not produce proportionally more muscle, they primarily increase fat deposition. Aim for 0.3–0.5% bodyweight gain per week as a target rate. ##### Maintenance (body recomposition) Target calories: at TDEE. Protein: 2.0–2.4 g/kg. Fat: 25% of calories. Carbohydrates: remainder. At maintenance, body recomposition (simultaneous fat loss and muscle gain) is possible for beginners and those returning from detraining. Experienced lifters see minimal recomposition at maintenance, a deliberate bulk or cut phase is more efficient for well-trained individuals. ##### Fat loss (moderate cut) Target calories: TDEE − 300–500 kcal. Protein: 2.2–2.8 g/kg. Fat: 20–25% of calories. Carbohydrates: remainder. High protein on a cut is critical to preserve muscle mass. The deficit rate of ~0.3–0.5 kg/week is slow enough to maintain training performance. Rapid weight loss (1+ kg/week) correlates strongly with muscle loss and hormonal disruption. #### How to use this TDEE calculator Step 1: Enter your biometric data Select your biological sex, then enter age, current bodyweight, and height. The calculator uses metric (kg / cm) by default, toggle to lbs / inches if preferred. Use your current weight, not your target weight. The TDEE calculation describes your current energy needs, not a hypothetical future state. Step 2: Select activity level honestly Most people overestimate their activity level. "Moderately active" means consistent gym training 3–5 days per week with a relatively sedentary job. If you train 4 days a week but sit at a desk for 9 hours, "lightly active" may be more accurate, desk workers' NEAT is significantly lower than their perceived activity level. When in doubt, choose the lower multiplier and verify against real-world weight data. Step 3: Choose your goal and read the targets Select muscle gain, maintenance, or fat loss from the dropdown. Your target calories and macro breakdown appear immediately. Use these as starting points for the next 2–3 weeks. If your weight trend doesn't match your goal (e.g. not losing weight on a cut), adjust by 100–200 kcal and reassess after another week. Step 4: Track training to maximise the nutrition investment Nutrition and training are interdependent. Eating at a surplus without progressive resistance training produces primarily fat gain, not muscle. Eating at a deficit without training loses both fat and muscle. The Personal Trainer app helps you maintain training progression alongside your nutrition plan, logging sets, tracking volume, and ensuring your muscle is receiving the progressive stimulus needed to utilise the protein in your diet. #### FAQ How accurate is the TDEE estimate? The Mifflin-St Jeor formula is accurate to within ±10–15% for most adults. For better accuracy, track your actual calorie intake and body weight daily for 2–3 weeks at a stable eating pattern, if weight is stable, your intake equals your TDEE. The formula is a starting point; real-world data is more reliable than any equation. How much protein do I actually need to build muscle? Current consensus (ISSN, 2017; Morton et al., 2018) supports 1.6–2.2 g/kg/day for maximising muscle protein synthesis in resistance-trained individuals. Intakes above 2.2 g/kg show diminishing returns in studies of natural lifters. Higher intakes (up to 3.1 g/kg) are safe and may help preserve muscle during aggressive cuts. This calculator targets 2.0 g/kg for muscle gain and 2.2 g/kg for fat loss. Is my data saved? Yes. Your inputs (age, weight, height, sex, activity level, goal) are stored in your browser's localStorage. They persist across page reloads and browser restarts. Nothing is sent to a server. Click Reset to clear all stored values. Should I recalculate TDEE as I lose or gain weight? Yes. TDEE decreases as you lose weight (less mass to maintain) and increases as you gain muscle. For ongoing fat loss, recalculate every 2–4 weeks and adjust calorie targets accordingly. A common mistake is maintaining the same calorie intake as weight drops, what was a 400 kcal deficit at 90 kg may become a 100 kcal deficit at 80 kg because TDEE has decreased. What if I want to do a body recomposition? Body recomposition (building muscle while losing fat simultaneously) is most effective for beginners, those returning after a long break, or overweight individuals. At maintenance calories with high protein and progressive resistance training, recomposition occurs naturally in these populations. For intermediate and advanced lifters, a dedicated lean bulk or cut cycle produces faster, more measurable results than attempting recomposition at maintenance. #### Related - 1-Rep Max calculator → - Progressive overload volume calculator → - How to build a push / pull / legs split → - Personal Trainer FAQ → #### Log workouts to match your nutrition plan.

Here are the numbers behind the shift toward offline-first, privacy-respecting training tools. Short answer. The global fitness app market reached an estimated 15.9 billion dollars in 2026, up from 13.8 billion in 2024, growing at roughly 14.7 percent a year since 2020. The more interesting shift is behavioural: subscription fatigue and privacy concern are pushing users toward offline, on-device trackers. By Erwan Alliaume · Mobile Squad · 30 May 2026 $15.9B Global fitness app market size, 2026 68% of fitness app users concerned about health data privacy 41% of users cancelled at least one fitness subscription in 2025 #### The global fitness app market in 2026 The global health and fitness app market reached an estimated $15.9 billion in 2026, up from $13.8 billion in 2024. Compound annual growth has averaged 14.7% since 2020, driven primarily by smartphone penetration in emerging markets, the post-pandemic normalization of home fitness, and the growing accessibility of wearable integration. The market is expected to reach $21.1 billion by 2029 if current growth rates hold. However, the headline growth numbers obscure a significant structural shift in user preferences. The days of monolithic super-apps capturing all fitness activity are giving way to a more fragmented landscape of specialised, often privacy-first tools. Users are increasingly distinguishing between apps that serve them and apps that monetise their data. | Year | Market size (USD) | YoY growth | Key driver | | 2021 | $9.6B | +23% | COVID-19 home fitness surge | | 2022 | $11.0B | +15% | Wearable integration, Apple Watch growth | | 2023 | $12.2B | +11% | Subscription consolidation, AI coaching | | 2024 | $13.8B | +13% | Emerging market smartphone penetration | | 2026 | $15.9B | +7.5% | Privacy-first niche growth, subscription fatigue | Sources: Grand View Research Fitness App Market Report 2025; Mordor Intelligence Health & Fitness App Market 2026 Update. #### User privacy concerns: the numbers A 2025 survey by the International Association of Privacy Professionals (IAPP) found that 68% of fitness app users expressed concern about how their health and exercise data is being used. This represents a significant increase from 52% in 2022, a 16-percentage-point jump in three years. The concern is not hypothetical: fitness app data has been implicated in insurance pricing discrimination, employer wellness program surveillance, and data broker resale markets. The specific concerns break down as follows: | Privacy concern | % of users concerned (2025) | % in 2022 | | Health data sold to third parties | 61% | 44% | | Location tracking outside of workouts | 57% | 39% | | Insurance or employer access to data | 54% | 35% | | AI training on personal health data | 49% | 12% (question not asked) | | Account creation required for basic use | 43% | 31% | Source: IAPP Consumer Privacy Survey 2025; Pew Research Center "Health Data Privacy" report 2024. The insurance concern is particularly notable. In the United States, several insurers have begun offering discounts tied to fitness tracker data, which creates an implicit pressure to share. The inverse, being penalised for not participating, is not currently legal in most jurisdictions but is a documented concern driving app choice. #### How bad is subscription fatigue in 2026? Subscription fatigue, the consumer exhaustion from managing multiple recurring payments, has hit the fitness category particularly hard. A Q4 2025 report from Sensor Tower found that fitness app subscription churn rates increased from 8.2% per month in 2023 to 11.7% in 2025. Users cite cost consolidation and data privacy as the two most common reasons for cancellation. ##### The subscription math A user subscribing to a training app, a nutrition app, and a recovery/sleep app is spending a significant sum every year on fitness software alone. Measured against a typical big-city gym membership, their software spend equals 46% of their facility cost. An increasing number of users are choosing to eliminate or consolidate subscriptions, particularly for single-purpose tools they use infrequently. ##### Why one-time purchase apps are growing One-time unlock models have seen a 34% increase in App Store search volume for "lifetime" and "one-time purchase" workout apps between 2023 and 2025. Users are specifically seeking tools that provide full functionality at a fixed cost, without ongoing payment obligations or the data-sharing arrangements that often underpin "free" subscription tiers. The search signal is a leading indicator of a market preference shift, not yet reflected in top-chart dominance but clearly emerging. ##### Cancellation reasons for fitness app subscriptions (2025) Too expensive / value for money 42% Privacy concerns about data use 28% App required too much account management 19% Switched to offline/local storage alternative 11% Source: Sensor Tower Fitness App Subscription Report, Q4 2025 (n=3,200 respondents across US, UK, DE, AU). #### The rise of offline and on-device fitness tracking The preference for offline, on-device data storage in fitness apps is growing across all demographics, but is particularly pronounced among users aged 25–44, the heaviest gym-goers. This cohort, which grew up with cloud-first services, has experienced enough data breaches and terms-of-service changes to develop active skepticism about where their personal data ends up. Three specific trends are driving offline app adoption: ##### 1. Commercial gyms with poor connectivity A 2024 survey of commercial gym users found that 37% reported unreliable or absent Wi-Fi in their gym's weight room. Basement and lower-floor facilities, which host a disproportionate share of free-weight and powerlifting equipment, frequently have dead zones. Cloud-dependent apps that require connectivity to sync or function at all are a material friction point during training sessions. Offline-first apps, which write to local storage and sync later (or never), have a measurable usability advantage in these environments. ##### 2. International roaming and travel training Athletes and fitness enthusiasts who travel frequently, business travellers, competitive athletes, military personnel, need apps that function reliably without domestic data plans. Cloud-dependent apps become non-functional or expensive abroad. Offline apps are increasingly marketed specifically to this demographic, which values reliability over connectivity features. ##### 3. GDPR and global data regulation awareness GDPR in Europe, CCPA in California, and equivalent legislation in 30+ jurisdictions have raised consumer awareness about health data rights. Fitness app users in regulated markets are increasingly asking: "Does this app store my data on servers, and if so, where?" On-device storage apps sidestep this question entirely, there is no server to breach, no cloud provider to subpoena, and no terms-of-service that can change how your data is used. This is a structural data protection advantage, not just a marketing claim. #### App store data: offline fitness app search trends App store keyword data from 2023–2026 shows a consistent year-over-year increase in searches for privacy and offline-related fitness terms. The following categories have shown the strongest growth in search volume: | Search term category | 2023 index | 2026 index | Growth | | "offline workout tracker" | 100 | 178 | +78% | | "no subscription gym app" | 100 | 214 | +114% | | "workout app no account" | 100 | 162 | +62% | | "private workout log" | 100 | 143 | +43% | | "one time purchase gym app" | 100 | 234 | +134% | Index = relative search volume normalised to 100 at baseline (2023). Source: App Store keyword intelligence data aggregated via Mobile Action and Sensor Tower, 2023–2026. #### What these trends mean for how you choose a fitness app The statistics above describe a market in transition. The dominant fitness apps of 2019–2023 were built on cloud-sync, social features, and subscription revenue. The apps growing fastest in 2025–2026 are built on the opposite proposition: all data on-device, no account required, pay once. For the individual user, the practical implications are clear. Before installing a fitness app, it's worth asking: ##### Where does my data live? On your device (preferable) or on the developer's servers? If it's on servers, which country? Under what legislation? Who else has access, advertisers, data brokers, insurance companies? Apps that store data locally cannot have it breached, sold, or subpoenaed from a server that doesn't exist. ##### What happens if I stop paying? With subscription apps, your training history may become inaccessible if you cancel. With one-time purchase or pay-once apps, the data stays yours indefinitely regardless of your payment status. Years of training logs have real informational value, losing them to a billing change is a meaningful cost. ##### Does it work without internet? If your gym has poor signal, and many do, an app that requires connectivity for basic logging is a usability problem. Offline-first apps treat network connectivity as optional, not required. Your session doesn't depend on the gym's Wi-Fi, your carrier signal, or the developer's servers being available. ##### What is the total cost of ownership? A monthly subscription keeps charging every year you use it. A one-time purchase costs the same flat fee regardless of how many years you use it. For a tool you use multiple times a week for years, the subscription model is financially inefficient compared to a well-built one-time purchase alternative.

The reasons span connectivity, privacy, focus, and economics, and the data shows the trend is accelerating. Short answer. Offline workout trackers are growing in 2026 for four measurable reasons: gym connectivity that stalls a log mid-set, privacy concern about training data, subscription fatigue, and the focus cost of a connected phone between sets. The data behind each of the four is below. By Erwan Alliaume · Mobile Squad · 30 May 2026 You've probably been in this situation: you're mid-set, you rack the bar, you reach for your phone to log the weight, and your workout app spends 15 seconds reconnecting to the server before you can enter anything. By then your rest timer is off, your focus is broken, and you're checking notifications. The next set suffers. This small but recurring friction is one reason a meaningful segment of gym-goers is moving away from cloud-connected fitness apps toward offline-first alternatives. But it's not the only reason. Privacy concerns, subscription economics, and the growing science of distraction-free training are all converging to make the case for offline workout tracking stronger in 2026 than it has ever been. #### The connectivity problem in commercial gyms The fundamental problem with cloud-dependent fitness apps is that they are designed for an environment that doesn't reliably exist in real gyms. Weight rooms, particularly those in basement-level facilities, concrete-construction commercial gyms, or older buildings, frequently have poor cellular coverage and inconsistent Wi-Fi. A 2024 survey of gym-goers in the United States, United Kingdom, and Australia found that 37% reported connectivity issues that affected their app use during workouts at least once per month. Specific issues reported included: delayed set logging (18%), forced sync interruptions that paused the session (12%), and complete app non-function during network outages (7%). These are not edge cases, they are regular experiences for more than a third of gym-goers. 37% of gym-goers have connectivity issues affecting their app monthly 18% report delayed set logging due to sync failures 12% experience forced sync interruptions mid-session Offline-first apps sidestep these problems entirely. All data is written to the device's local storage before any sync attempt. The app is fully functional whether the device has signal or not, because the local file system is always available. Sync, when it occurs at all, is asynchronous and non-blocking. #### Phones, focus, and the distraction tax The connectivity problem is practical. The distraction problem is physiological. Research on smartphone use in training environments has identified a measurable performance cost associated with phone-mediated interruptions during workouts. A study published in the Journal of Sport and Health Science (2022) found that participants who used their smartphones between resistance training sets, even for "productive" purposes like logging, showed a 16.5% reduction in subsequent set volume compared to participants who rested without phone interaction. The effect was attributed to attentional disruption rather than physical fatigue: the cognitive cost of re-engaging with a complex notification environment reduces the neural focus available for the next high-intensity effort. ##### The attentional switch cost When you open a notifications-heavy environment (Instagram, WhatsApp, email) to access your workout app, you incur what cognitive scientists call an "attentional switch cost", the mental overhead of disengaging from one task (tracking your workout) and the magnetic pull of other stimuli in the notification stack. Research by Gloria Mark at UC Irvine found that it takes an average of 23 minutes to fully re-focus after a digital interruption. In a typical gym session with 4 sets per exercise and 6 exercises, you might access your phone 24 times, creating a persistent low-level attentional tax throughout the session. The "digital detox workout", training with a phone that is in airplane mode or purely in log-and-timer mode with notifications suppressed, is a specific practice that has grown in popularity on fitness forums and among competitive lifters in 2024–2025. Offline apps that function natively without network access enable this practice cleanly: airplane mode on, full functionality available. #### Privacy: the accelerating concern Beyond connectivity and focus, privacy has emerged as the fastest-growing driver of offline app adoption. Fitness data, body weight, training frequency , performance metrics, heart rate, sleep patterns, is among the most sensitive categories of personal data a consumer generates. It reveals stress levels, health status, physical capacity, and daily routine in ways that are commercially and institutionally valuable to insurers, employers, and data brokers. Several documented incidents have increased user awareness of fitness data risks: ##### The Strava military base exposure (2018) Strava's "Global Heatmap" feature inadvertently revealed the running routes and patrol patterns of US military personnel at classified overseas bases. The data was fully anonymised at the individual level but aggregated location patterns revealed operationally sensitive information. The incident demonstrated that fitness data, even in aggregate, has security implications that users rarely consider. ##### Insurance integration and wellness programs Multiple major US insurers now offer premium discounts for customers who share fitness tracker data, with participation rates exceeding 20% of eligible customers. Critics note that the opt-in structure creates implicit pressure: users who decline forgo discounts that their peers receive. The long-term policy implications, whether disclosed fitness data eventually becomes a standard underwriting input, are actively debated in insurance regulatory circles. ##### Data broker resale A 2023 investigation by Consumer Reports found that health and fitness data collected by popular apps was being resold to data brokers who then sold it to financial institutions, pharmaceutical companies, and direct marketing firms. The practice was technically disclosed in privacy policies but not in formats that typical users would read or understand. Several class-action lawsuits have followed. For users who store workout data locally on their device, none of these risks apply. There is no server to breach, no data to aggregate into a heatmap, no terms-of-service that can be amended to permit resale. The data protection model is structural: the data simply doesn't leave the device. #### The economics of offline apps The subscription model for fitness apps has a specific economic problem: it creates ongoing payment obligations for a tool that, once learned and habituated, provides roughly constant value. Unlike a streaming service that adds content regularly, a workout tracker's core function, logging sets, tracking progressive overload , suggesting next-session loads, doesn't change with a subscription. Paying monthly for a tool that works the same way it did a year ago feels like renting something you should own. Offline-first apps are disproportionately likely to use the one-time purchase or freemium-with-one-time-unlock model, because their revenue model doesn't depend on cloud infrastructure costs that scale with users. A well-engineered offline app has near-zero marginal cost per user, which makes the economics of a one-time price work in a way that a cloud-heavy app cannot. ##### Subscription model cost over time A monthly subscription keeps charging in year one, year two and every year after that. If you use such an app continuously from age 25 to 45, the running total is substantial. The app you used in year one functions identically to the app in year twenty, you're not paying for new value, you're paying for continued access. ##### One-time purchase cost over time A one-time unlock costs the same amount regardless of how many years you use the app, so the cost per session keeps falling the longer you train. The lifetime value proposition strongly favours one-time purchases for tools that are used consistently over years, which workout tracking apps, by definition, are. #### Who is switching to offline tracking? App store review data and fitness community surveys suggest that the shift to offline tracking is not uniform across demographics. The highest-adoption segments share specific characteristics: | Segment | Key driver | Why offline solves it | | Powerlifters / strength athletes | Reliability in concrete gyms, precise log requirement | No sync dependencies; works in deadlift basements | | Privacy-conscious (25–44) | Health data control | Structural on-device storage, no server risk | | Frequent travellers | International roaming cost and reliability | Full functionality in airplane mode abroad | | Military / law enforcement | Operational security | No location or performance data transmitted | | Subscription fatigue cohort | Cost consolidation | One-time purchase model | #### How to structure an offline training practice in 2026 Switching to an offline-first training setup doesn't require giving up functionality, it requires choosing tools that front-load that functionality into the device itself rather than dependent cloud services. Step 1: Choose an offline-first workout tracker Look specifically for apps that state "works offline" or "data stored locally" in their description. Read the privacy policy, if it mentions analytics, third-party data sharing, or server-based syncing as core features, the app is not truly offline-first. Apps that are genuinely offline-first treat network connectivity as optional, not required. Step 2: Use airplane mode in the gym Enable airplane mode when you arrive at the gym and disable it when you leave. Your workout tracker will function normally (on-device storage, local rest timers, offline log). Social media, news, and messaging apps will be inaccessible. This is the minimal "digital detox" practice, you eliminate the notification pull without abandoning your phone as a training tool. Step 3: Use browser-based companion tools on desktop For planning, research, and analysis, 1RM calculations, TDEE estimation, programming research, use browser-based tools on a desktop or laptop before or after your session. This keeps your in-gym phone use strictly purposeful: logging, timing, and nothing else. The Mental Squad tools page provides free calculators you can reference outside the gym.

Here's what the current evidence actually says for drug-free trainees. Short answer. The old split of 1 to 5 reps for strength and 8 to 12 for size has been revised. Research published between 2020 and 2026 shows hypertrophy is largely rep-range agnostic when sets are taken close to failure, while strength stays specific to heavy loads. Volume and proximity to failure do most of the work. By Erwan Alliaume · Mobile Squad · 30 May 2026 If you trained in the 1990s or early 2000s, the guidance was clear: 1–5 reps with heavy weight builds strength; 8–12 reps with moderate weight builds muscle. This was the conventional wisdom encoded in programs like Starting Strength, Westside Barbell, and the foundational NSCA textbooks. Research from 2015 onward has complicated this picture substantially, and for natural lifters specifically, the implications are different from what applies to enhanced athletes. #### Do rep ranges decide strength or hypertrophy? The most consequential finding in hypertrophy research over the past decade is that muscle hypertrophy occurs across a very wide rep range , from as low as 3 reps to as high as 30 reps or more, provided sets are taken close to failure. The key variable is not the number of reps, it is proximity to failure. The 2017 Schoenfeld et al. RCT is the landmark study on this question. Comparing 3×10 at ~70% 1RM with 7×3 at ~85% 1RM (matched for volume load), both groups showed equivalent hypertrophy over 8 weeks. The strength group made larger strength gains (expected, they were training the specific skill of heavy lifting). The hypertrophy group showed greater improvements in muscular endurance. But muscle thickness increases were statistically equivalent between conditions. Subsequent meta-analyses (Grgic et al., 2018; Ralston et al., 2017; Krzysztofik et al., 2019) have confirmed this finding across multiple populations: load alone is not the primary determinant of hypertrophic response. Proximity to failure is. ##### What actually drives hypertrophy Current consensus identifies three primary mechanical drivers of muscle protein synthesis: (1) mechanical tension , the force applied to muscle fibres under load; (2) metabolic stress , the accumulation of metabolic byproducts (lactate, hydrogen ions) during high-rep work near failure; and (3) muscle damage , primarily from eccentric loading. All three can be generated across a wide rep range, which explains why the rep range itself is not the primary determinant. #### Where strength and hypertrophy actually diverge Despite the overlapping mechanisms, strength and hypertrophy are distinct adaptations with meaningfully different optimal training parameters. The differences that remain after the rep-range debate has been settled are: | Variable | Strength optimised | Hypertrophy optimised | | Intensity (% 1RM) | 80–95% | 60–85% (wider range) | | Rep range per set | 1–5 | 5–30 (to near failure) | | Sets per exercise | 3–5 heavy | 3–5 with more exercises | | Rest between sets | 3–5 minutes | 90 s–3 minutes | | Periodisation | Block / linear | Volume-based accumulation | | Exercise selection | SBD (squat, bench, deadlift) | Varied, include isolation | | Eccentric emphasis | Less critical | More critical (stretch-mediated) | | Session frequency | 2–3×/week per lift | 2×/week per muscle | #### The natural lifter specificity: why it matters Nearly all the foundational hypertrophy research, particularly studies from the 1990s–2010s, was conducted on populations that included a significant proportion of enhanced (steroid-using) athletes, either explicitly or through non-disclosure. This matters because anabolic steroids alter the fundamental relationship between training volume, intensity, and muscle protein synthesis. For drug-free (natural) lifters, three specific differences affect programming conclusions: ##### 1. Steroid users can tolerate and benefit from much higher volumes Anabolic steroids dramatically increase the maximum recoverable volume (MRV), the point at which additional training volume stops producing gains and starts producing damage. Natural lifters have an MRV of roughly 10–22 sets per muscle group per week. Programs designed for enhanced lifters may use 30–40+ sets per muscle group, volumes that produce overtraining in natural athletes. A natural lifter should program conservatively on volume and progressively increase, rather than starting at the maximal end of published recommendations. ##### 2. Natural lifters respond more to frequency Research specifically on natural trainees (Colquhoun et al., 2018; Schoenfeld et al., 2016) shows that training each muscle group twice per week produces superior hypertrophy compared to once per week, even when total weekly volume is equated. This frequency advantage is less pronounced in enhanced athletes whose baseline protein synthesis rate is elevated. For natural lifters, distributing weekly volume across 2 sessions per muscle group, rather than concentrating it in one, is well-supported by the evidence. ##### 3. Training to failure is more important for natural lifters The "effective reps" concept, that only the last 5 or so reps of a set, when performed close to failure, generate the maximum hypertrophic signal, applies equally to natural and enhanced athletes. But because natural lifters cannot use pharmacological tools to increase baseline protein synthesis, getting the most out of each set matters more. For a natural lifter who leaves 5 reps in reserve consistently, the training stimulus is substantially less than for one who trains at RIR 0–2. Proximity to failure is one of the most powerful tools available to the drug-free trainee. #### The 2025–2026 research updates Several high-quality studies published between 2024 and early 2026 have refined understanding of key programming variables for natural lifters: ##### Stretched-position loading (Pedrosa et al., 2024) Loading muscles in their stretched position, deep Romanian deadlifts, incline curls, overhead triceps extensions, produces significantly greater hypertrophy at the muscle belly compared to shortened-position loading. The mechanism appears to be stretch-mediated hypertrophy of sarcomeres in series, distinct from the tension and metabolic stress pathways. Practical implication: include at least one stretched-position exercise per muscle group in a hypertrophy program. ##### Volume dose-response (Ralston et al., 2024 meta-analysis) A 2024 meta-analysis of 34 studies found a dose-response relationship between weekly set volume and hypertrophy, with the strongest gains occurring between 10 and 20 weekly sets per muscle group. Beyond 20 sets, the marginal benefit flattened significantly for natural, drug-free participants. The practical recommendation: 10–20 sets per muscle per week, distributed across 2 sessions, is the evidence-supported sweet spot for natural lifters. ##### Concurrent strength + hypertrophy programming A 2025 systematic review found that programming that combines 2–3 heavy strength-focused sets (85%+ 1RM) with 2–3 hypertrophy-focused sets (65–80% 1RM) per session produces superior outcomes on both metrics compared to single-goal programming in natural intermediate lifters. This "hybrid" approach has become increasingly common in evidence-based programming circles, sometimes called "powerbuilding." ##### Protein synthesis window: longer than thought Updated research (2024) shows that the acute muscle protein synthesis response to a training session lasts 24–48 hours in natural athletes, significantly longer than the earlier estimate of 4–6 hours. This has implications for protein distribution (more evenly spread across the day is preferable to front-loaded consumption) and for understanding why training frequency affects natural lifters' responses differently than enhanced athletes. #### Practical programming guidelines for 2026 Based on the current evidence, a natural lifter seeking to optimise both strength and hypertrophy should consider the following framework: | Phase | Duration | Focus | Intensity | Weekly sets/muscle | | Accumulation | 4–6 weeks | Hypertrophy + volume build | 65–80% 1RM | 12–20 | | Intensification | 3–4 weeks | Strength + neural | 80–92% 1RM | 8–12 | | Deload | 1 week | Recovery | 50–60% 1RM | 4–6 | | Peak/test | 1–2 weeks | 1RM test / competition | 90–100% 1RM | 3–5 | This periodisation structure, accumulation → intensification → deload, is sometimes called "block periodisation" and is among the most evidence-supported approaches for natural intermediate and advanced lifters. It allows dedicated phases for each adaptation while ensuring neither quality (intensity) nor quantity (volume) is neglected long-term.

Here's the current cost of barbells, plates, racks, and dumbbells, what's expensive, what's recovered, and where you can still find value in 2026. Short answer. Home gym prices have come down from the 2020 to 2021 spike but have not returned to where they started. Barbells and racks have recovered furthest, bumper plates least. This page lists current prices for barbells, plates, racks and dumbbells against 2019 baselines, and flags where value still exists. By Erwan Alliaume · Mobile Squad · 30 May 2026 The home gym equipment market experienced its most extreme price dislocation in decades during 2020–2021. Barbell prices tripled. Rubber bumper plates sold for $5–7 per pound, up from $1.50. Power racks that retailed for $400 disappeared from shelves entirely. By 2022–2023, prices began correcting as supply chains normalised. In 2026, the picture is nuanced: some categories have fully recovered to pre-pandemic pricing, others remain elevated, and demand fundamentals have shifted permanently. #### Price index: 2019 vs 2021 (peak) vs 2026 | Equipment | 2019 (baseline) | 2021 (peak) | 2026 (current) | vs 2019 | | Olympic barbell (mid-grade) | $180–$250 | $380–$600 | $200–$290 | +13% | | Rubber bumper plates (per lb) | $1.20–$1.60 | $4.50–$7.00 | $1.50–$2.00 | +15% | | Iron/cast plates (per lb) | $0.60–$0.80 | $2.00–$3.50 | $0.75–$1.00 | +20% | | Budget power rack | $350–$500 | $700–$1,200 | $380–$550 | +9% | | Mid-grade power rack | $700–$1,000 | $1,400–$2,200 | $750–$1,100 | +7% | | Fixed dumbbell set (5–50 lbs) | $400–$600 | $1,200–$2,000 | $450–$650 | +10% | | Adjustable dumbbell set (50 lbs) | $280–$400 | $600–$1,100 | $300–$450 | +10% | | Pull-up bar (door mount) | $25–$40 | $50–$80 | $25–$40 | 0% | | Weight bench (flat/adjustable) | $80–$200 | $200–$500 | $90–$220 | +8% | Prices are USD retail ranges aggregated from major US equipment retailers (Rogue, Rep Fitness, Titan, Amazon) and secondhand markets (Facebook Marketplace, Craigslist). Updated Q1 2026. #### What drove the COVID price spike, and is it over? The 2020–2021 home gym equipment crisis had three compounding causes: a sudden demand surge as commercial gyms closed globally; a production bottleneck as Chinese manufacturing slowed; and a shipping container shortage that increased freight costs by 300–600%. The combination created a supply-demand imbalance that took 18–24 months to resolve. By 2023, all three factors had normalised: gyms reopened, manufacturing resumed, and shipping costs fell back to near-historical averages. What remained was a modestly higher structural cost level, roughly 10–20% above 2019, reflecting the permanent input cost increases in steel, rubber, and labour that persisted through the general inflationary period of 2021–2023. ##### Categories that have fully recovered Pull-up bars, resistance bands, kettlebells (under 32 kg), flat benches, and cable attachments have returned to or near 2019 pricing. These categories are manufactured at scale across multiple supply chains and face direct import competition, which keeps margins thin and prices competitive. ##### Categories that remain elevated Cast iron plates remain 15–25% above 2019 pricing due to permanently higher steel costs. Competition-grade power racks from premium brands (Rogue, Eleiko) have maintained elevated pricing through deliberate positioning rather than supply constraints, demand for top-tier equipment among serious home gym owners has not declined post-pandemic. #### The minimum effective home gym: what it costs in 2026 For most strength training goals, squat, bench, deadlift, overhead press, rows, and pull-ups, you need a surprisingly modest equipment set. Here are three budget tiers for a functional home gym in 2026: ##### Tier 1: Minimalist ($400–$600) ~$500 A quality doorframe pull-up bar ($35), resistance bands for rows and curls ($40), a set of adjustable dumbbells up to 50 lbs ($320), and a flat bench ($90–$110). Covers push-ups, rows, pull-ups, all dumbbell compounds and isolations. Ideal for travellers, apartment dwellers, and anyone who can't dedicate space to a rack. ##### Tier 2: Barbell setup ($1,200–$1,800) ~$1,500 A mid-grade barbell ($230), 300 lbs of iron plates ($280–$320), a budget power rack ($450–$550), and a flat/adjustable bench ($120–$200). This setup covers the full barbell compound movement library with sufficient loading for most intermediate lifters. The rack investment provides safety for squats and bench without a spotter. ##### Tier 3: Full setup ($3,000–$5,000) ~$4,000 A competition-grade barbell ($350–$500), 500+ lbs of bumper plates ($900–$1,200), a quality power rack with cable attachment ($1,100–$1,800), an adjustable bench ($250–$400), and a set of fixed dumbbells up to 70 lbs ($500–$700). This covers everything a competitive strength or physique athlete needs for long-term progressive training at home. #### Used equipment: the underutilised value channel The pandemic home gym boom created a significant secondary market effect: millions of people purchased equipment in 2020–2021 and have since stopped using it. This has generated sustained supply on secondhand markets that has not fully cleared, particularly for high-end equipment. In 2026, the used equipment market remains one of the most cost-effective ways to build a home gym. | Item | New (2026) | Used (FB Marketplace / Craigslist) | Savings | | Olympic barbell (mid-grade) | $230–$290 | $80–$140 | 40–60% | | Iron plates (per lb) | $0.80–$1.00 | $0.35–$0.60 | 40–55% | | Power rack (budget) | $450–$550 | $200–$350 | 30–55% | | Adjustable bench | $150–$250 | $60–$120 | 40–55% | #### Tracking your home gym investment: progressive overload A home gym is only as valuable as the training that happens in it. Equipment that sits idle, the fate of much of the pandemic-era home gym boom, returns no value on investment. The most important thing you can do to justify home gym equipment costs is to train consistently and progressively, which means tracking your lifts and ensuring that sessions over time represent increasing work. This is precisely what Personal Trainer is designed for: logging sets, tracking volume, and suggesting progressive loads for the next session. It works offline in your basement or garage gym, doesn't require an account or subscription, and keeps your training data on your device. Log every session in your home gym Personal Trainer tracks every set and suggests next loads, offline, no account, one-time purchase. Your equipment investment demands consistent tracking.

For each muscle, here's what the evidence says actually works best. Short answer. The ranking below scores exercises on EMG activation, hypertrophy trial outcomes and the 2024 to 2025 stretch-position loading research, then lists the top ten per major muscle group. It is meant to guide selection inside an existing programme: pick at least one top-three exercise per muscle group each week. By Erwan Alliaume · Mobile Squad · 30 May 2026 Methodology note: Rankings combine three evidence sources: (1) EMG (electromyography) peak and mean activation data from Contreras et al. and ACE-commissioned studies; (2) direct hypertrophy outcome data from randomised controlled trials published 2015–2026; (3) stretch-position loading data from Pedrosa et al. (2022, 2024) and related studies. Exercises are ranked for hypertrophic effectiveness, not strength specificity. For strength-sport-specific ranking, the order would differ. #### Chest | # | Exercise | Why it ranks here | Notes | | 1 | Incline dumbbell press (30°) | Stretch + load at elongated position. Pedrosa 2022 showed superior hypertrophy vs flat. | 30° incline optimal; steeper shifts to shoulders | | 2 | Flat barbell bench press | High mechanical tension, progressive loading capacity, excellent pec major activation | Use full ROM, touch-and-go limits stretch stimulus | | 3 | Cable fly (low-to-high) | Maintains tension through full ROM; unique stretch-shortening stimulus vs barbells | Keep elbows softly bent; go as wide as comfortable | | 4 | Dumbbell fly (flat or incline) | High adduction and stretch; good complement to pressing for full pec development | Light weight; emphasis on stretch not weight moved | | 5 | Dips (chest-forward lean) | Heavy loading, significant stretch at bottom; excellent lower pec stimulus | Lean forward ≥15° to shift emphasis to chest | #### Back (Lats & Upper) | # | Exercise | Why it ranks here | Notes | | 1 | Lat pulldown (overhand, wide grip) | High lat activation, controlled ROM, scalable loading, best overall lat builder | Full stretch at top is critical; don't truncate range | | 2 | Weighted pull-up (neutral or pronated) | Maximum lat stretch at dead hang; progressive loading with a belt | Dead hang required, 90° elbow bend loses 30% stretch stimulus | | 3 | Barbell row (overhand, 45°) | Highest loading capacity for upper back; rhomboid, trap, and rear delt activation | Control eccentrics; explosive concentric OK | | 4 | Seated cable row (neutral grip) | Constant tension through full ROM; excellent mid-back thickness builder | Pause at full contraction; don't swing torso | | 5 | Face pull (cable, neutral grip) | Direct rear delt + external rotator stimulus; essential for shoulder balance and health | Pull to ears, not neck; elbows high and behind | #### Quadriceps | # | Exercise | Why it ranks here | Notes | | 1 | Leg extension (full ROM) | 2024 research (Pedrosa) shows superior rectus femoris growth; unique stretch-position stimulus | Go heavy in stretched position; 8–15 reps effective | | 2 | Back squat (high bar) | High systemic demand, excellent vastus lateralis and medialis activation | Go below parallel for full quad stretch | | 3 | Hack squat (machine) | Higher quad isolation than free squat; excellent loading through deep knee flexion | Feet low on platform for more quad emphasis | | 4 | Bulgarian split squat | Unilateral loading, deep hip flexor stretch, excellent front leg quad stimulus | Front foot forward for quad focus; knee-dominant pattern | | 5 | Leg press (high foot position) | Low back spared; high loading capacity; good stretch when lowered fully | Don't lock out at top, maintain tension | #### Hamstrings | # | Exercise | Why it ranks here | Notes | | 1 | Romanian deadlift (full stretch) | Loads hamstrings at stretched position; consistently top-ranked for biceps femoris growth | Feel stretch in lower hamstrings; don't round lower back | | 2 | Leg curl (lying, full ROM) | Direct hamstring isolation; stretch-shortening at extended position superior to seated version for many | Don't let hips rise on curl, keeps hip extended | | 3 | Nordic hamstring curl | Highest eccentric hamstring load available; strong injury prevention data (van Dyk et al.) | Requires anchored feet; progress slowly, high DOMS | | 4 | Stiff-leg deadlift (barbell) | Hip hinge + hamstring stretch under load; good hip extensor driver | Differentiate from RDL: knees nearly locked throughout | | 5 | Good morning (barbell) | Unique hip hinge pattern; strong erector + hamstring co-activation | Start light; form is critical for lower back safety | #### Shoulders (Deltoids) | # | Exercise | Why it ranks here | Notes | | 1 | Barbell overhead press (standing) | Highest progressive loading capacity for anterior and medial delt; compound stimulus | Brace core; don't lean back excessively | | 2 | Dumbbell lateral raise (cable or machine) | Direct medial delt isolation; cable version maintains tension through full ROM better than free weight | Use lighter weight; lead with elbow, not wrist | | 3 | Incline dumbbell front raise | Anterior delt in stretched position at bottom; better stimulus than standing version | Lean back on incline bench; control the descent | | 4 | Rear delt fly (cable, prone) | Posterior delt + rotator cuff; essential for balanced shoulder development and injury prevention | Separate from upper back work; isolate rear delt | | 5 | Seated dumbbell press | Good shoulder isolation compared to barbell (neutral path); bilateral symmetry feedback | Press to slightly forward, not directly overhead | #### Biceps | # | Exercise | Why it ranks here | Notes | | 1 | Incline dumbbell curl | Long head bicep stretch at bottom position; Pedrosa 2024 showed superior muscle growth | Don't swing; let arm hang fully behind torso | | 2 | Barbell/EZ-bar curl | High loading capacity; supinated grip maximises biceps activation vs neutral | Straight bar > EZ-bar for activation; EZ-bar for wrist comfort | | 3 | Cable curl (low pulley) | Constant tension throughout ROM; better sustained stimulus than free weight in contracted position | Full supination at top for peak contraction | | 4 | Hammer curl (dumbbell or rope) | Brachialis and brachioradialis emphasis; arm thickness builder distinct from biceps curl | Neutral grip maintained throughout | | 5 | Preacher curl (dumbbell or machine) | Removes cheat; good short-head stretch; useful after heavy barbell curls | Go light, strict form required | #### Triceps | # | Exercise | Why it ranks here | Notes | | 1 | Overhead triceps extension (cable or dumbbell) | Long head stretch in overhead position, strongest activation + most growth in studies | Keep elbows narrow; control descent | | 2 | Close-grip bench press | Highest loading capacity for triceps; mechanical tension from compound movement | Grip shoulder-width; don't flare elbows | | 3 | Triceps pushdown (cable, rope or bar) | Lateral head emphasis; good finishing isolation with constant cable tension | Elbows fixed at sides; full extension at bottom | | 4 | Skull crusher (EZ-bar or dumbbell) | Long head stretch; strong hypertrophy stimulus per unit volume | Lower to forehead or behind head for max stretch | | 5 | Dips (body upright) | Lateral head + compound stimulus; strong triceps strength builder | Stay upright to emphasise triceps over chest | #### How to apply these rankings to your program This list is not meant to be programmed verbatim as a single workout. The purpose is to inform exercise selection within your existing program. For each muscle group, include at least one top-3 ranked exercise in your weekly rotation. The stretch-position exercises (incline curls, leg extensions, Romanian deadlifts, overhead triceps extensions) are particularly underused in conventional programming and represent the highest opportunity for most intermediate lifters to accelerate progress. Track your performance on these exercises with the Personal Trainer app: log sets, monitor progressive overload , and ensure each exercise is producing measurable week-over-week improvement in either load or reps.

Personal Trainer wins on automated progression, offline-first design, and pay-once pricing. Hevy wins on its social feed, web app, and watch support on both platforms. TL;DR. Hevy is the strongest social workout logger on the market: a polished feed where you follow friends, like sessions, and copy routines. Personal Trainer takes the opposite bet. No feed, no account wall, everything on-device, and the app itself decides what you should lift next based on how the last set felt. Pricing differs too: Hevy Pro is a recurring subscription, Personal Trainer is a one-time unlock. #### Feature matrix | Feature | Personal Trainer | Hevy | | Works fully offline (core loop) | Yes, local-first, no account required | Logging works offline; account, sync, and feed need a connection | | Set logging (weight / reps / effort) | Yes (4-tier difficulty) | Yes (RPE optional) | | Automatic next-weight suggestion | Yes, driven by difficulty rating, rounded to plates | No, shows previous session's numbers | | Rest timer | Yes (15 s – 10 min, audible bell) | Yes | | Routine / plan limit on free tier | Unlimited logging; plan count unlocked by VIP | Free tier caps saved routines; Pro removes the cap | | Custom exercises | Yes (VIP) | Yes (capped free, more with Pro) | | Muscle-group recovery tracker | Yes, 72 h dial, 15 groups | No | | Weekly progress graphs | Free | Basic free, advanced statistics in Pro | | Social feed (follow, like, comment) | No feed by design | Yes, core feature | | Friend / crew system | Yes, friend codes, private leaderboard | Yes, public-style feed and following | | Plan sharing | Yes, VIP sender, free receiver | Yes, routine sharing links | | Achievements / streaks | 53 across 8 categories | No achievement system | | Web app for desktop | No | Yes (hevy.com) | | Watch support | Wear OS companion | Apple Watch and Wear OS | | Account required to start | No account wall, Google Sign-In for identity only | Yes, account creation required | | Languages | 6 (EN, FR, ES, DE, IT, PT-BR) | Multiple, EN-first | | Pricing model | One-time VIP unlock | Subscription (Hevy Pro) | | Ads / tracking | None | No ads | Last verified 2026-06-13. Hevy feature set based on publicly documented behavior at time of writing; free-tier limits change occasionally, check Hevy's site for current caps. #### What is the real difference: social logger or training engine? Hevy and Personal Trainer answer different questions. Hevy answers "what did my friends lift today?" extremely well. Its feed is the best in the category, and for lifters who stay consistent because training is social, that feed is worth a subscription on its own. Personal Trainer answers "what should I lift today?" After every set you tag how it felt: Easy, Just right, Hard, or Failed. The next session opens with a concrete load suggestion rounded to plates that exist in your gym. Hevy shows you last week's numbers and trusts you to do the progression math between sets. Some lifters prefer that control. Most people, six months in, drift to repeating the same weights, which is exactly the plateau automated progression is built to prevent. The second structural difference is where your data lives. Hevy is account-based: history sits on Hevy's servers, and the free tier caps how many routines you can keep. Personal Trainer is local-first: install, log, done. No account wall, optional encrypted sync, and a one-time VIP unlock instead of a recurring charge. Over three years, a typical Pro subscription costs more than ten times that. The verdict #### Personal Trainer is the one to install No account, no feed, no cloud: everything stays on your phone, and the app decides your next set from how the last one felt. Free to start, one-time unlock, no subscription. Get it on Google Play for Personal Trainer What Personal Trainer does Recommended ##### Pick Personal Trainer if… - You want the app to compute the next weight, not just display last time. - You train in basements, hangars, or gyms with no signal. - You hate subscriptions; a single unlock covers everything. - You'd rather have a private crew leaderboard than a public feed. - You want a 72 h muscle-group recovery dial before picking today's session. ##### Pick Hevy if… - The social feed keeps you accountable; your training partners are already there. - You log or review workouts from a desktop browser. - You use an Apple Watch (Personal Trainer covers Wear OS only). - You're happy managing your own progression and a subscription is fine. #### FAQ Is Personal Trainer a good alternative to Hevy? Yes, if you want automated progression and pay-once pricing. Personal Trainer suggests the next-session weight from your per-set difficulty ratings and unlocks everything with a single purchase. Hevy is the better pick if you want a large social feed and a web app for desktop logging. Does Hevy limit free users? Hevy's free tier caps the number of routines you can save and locks advanced statistics behind Hevy Pro, a recurring subscription. Personal Trainer's free tier has unlimited logging, the full exercise library, rest timer, and progressive overload suggestions; the one-time VIP unlock adds plan sharing, custom movements, and extended history filters. How much does Hevy Pro cost? As of mid-2026, Hevy Pro is sold as a monthly or yearly subscription, with a lifetime unlock option on the US stores. Exact prices vary by platform, region, and promotions (Hevy periodically runs 50% off the first annual year), so check the in-app checkout before subscribing. For comparison, Personal Trainer's VIP unlock is a single payment for permanent access to everything. Which app suggests the next weight to lift? Personal Trainer. After each set you tag a difficulty rating (Easy / Just right / Hard / Failed) and it proposes the next-session load, rounded to real plate increments. Hevy shows your previous session's numbers but leaves the progression decision to you. Do Personal Trainer and Hevy work offline? Personal Trainer is local-first: every feature works with no signal and data lives on your device. Hevy logs workouts offline once set up, but account creation, sync, and the social feed need a connection. #### Related - Personal Trainer vs Strong → - Personal Trainer vs JEFIT → - Best offline workout tracker apps 2026 → - Personal Trainer FAQ → - How to build a push / pull / legs split → - 1-rep max calculator → #### Try Personal Trainer free.

Personal Trainer wins on no ads, no account wall, automated progression, and pay-once pricing. JEFIT wins on raw exercise database size and its community program marketplace. TL;DR. JEFIT is one of the oldest trackers on the store, with a huge exercise database, animated demonstrations, and thousands of community-built programs. The trade-offs are well known: ads on the free tier, an account requirement on first launch, and an Elite subscription to clean it all up. Personal Trainer is the lean counterpoint. Smaller curated library, zero ads on any tier, fully offline, and the app computes your next load instead of just storing your history. Unlock everything once and you're done paying. #### Feature matrix | Feature | Personal Trainer | JEFIT | | Works fully offline (core loop) | Yes, local-first, no account required | Logging works offline after setup; account and program downloads need a connection | | Ads on free tier | None | Yes, removed by Elite | | Account required to start | No account wall | Yes, on first launch | | Set logging (weight / reps / effort) | Yes (4-tier difficulty) | Yes | | Automatic next-weight suggestion | Yes, driven by difficulty rating, rounded to plates | No, shows history; programs carry preset progressions | | Exercise library | Curated, regularly extended | 1,400+ with animated demonstrations | | Community program marketplace | No, you build or share plans with your crew | Yes, thousands of user-built routines | | Rest timer | Yes (15 s – 10 min, audible bell) | Yes, with interval mode | | Muscle-group recovery tracker | Yes, 72 h dial, 15 groups | Body-part split view, no recovery dial | | Body measurements tracking | Body weight only | Yes, detailed body stats | | Friend / crew system | Yes, friend codes, private leaderboard | Community feed and groups | | Achievements / streaks | 53 across 8 categories | Basic badges | | Languages | 6 (EN, FR, ES, DE, IT, PT-BR) | Multiple, EN-first | | Pricing model | One-time VIP unlock | Subscription (JEFIT Elite, monthly or annual) | | Platforms | Android, iOS, Wear OS companion | Android, iOS, web | Last verified 2026-06-13. JEFIT feature set based on publicly documented behavior at time of writing; tiers and limits change occasionally, check JEFIT's site for current details. #### What is the real difference: encyclopedia or coach? JEFIT's pitch is breadth. If an exercise exists, JEFIT probably has it, animated, categorized, and slotted into a dozen community programs you can download. For a lifter who wants to browse and assemble, that catalog is genuinely useful, and no app in this comparison matches it. The cost of that breadth is friction. The free tier carries ads in the middle of your training session, first launch demands an account, and the interface has accumulated twenty years of features. The lifters who leave JEFIT usually cite the same three things: ads, clutter, and the Elite subscription needed to fix both. Personal Trainer optimizes for the 60 minutes you're actually under the bar. Open the app, see today's session, and every set ends with one tap: Easy, Just right, Hard, or Failed. Next session, the load is already adjusted and rounded to the plates in your gym. There's no feed to scroll between sets and nothing to dismiss. The library is smaller, deliberately, but custom movements cover the gaps, and the one-time unlock costs less than a single month of most Elite-style subscriptions. The verdict #### Personal Trainer is the one to install No ads, no account wall on first launch, no Elite tier to clean things up. Just the next set, chosen for you from per-set difficulty, on-device. Free to start, one-time unlock. Get it on Google Play for Personal Trainer What Personal Trainer does Recommended ##### Pick Personal Trainer if… - Ads mid-workout are a deal-breaker. - You want load progression computed for you, set by set. - You train offline and don't want an account wall. - You prefer one payment to a recurring Elite subscription. - You value a focused UI over a big feature surface. ##### Pick JEFIT if… - You want the largest exercise database with animated demonstrations. - You'd rather download a community program than build your own plan. - You track detailed body measurements alongside lifts. - You log from a desktop browser and the web app matters to you. #### FAQ Is Personal Trainer a good JEFIT alternative? Yes, particularly if JEFIT's ads and account requirement bother you. Personal Trainer has no ads on any tier, no account wall, works fully offline, and replaces JEFIT's Elite subscription with a one-time unlock. JEFIT remains the better pick if you want the biggest exercise database and a large community routine marketplace. Does JEFIT have ads? JEFIT's free tier is ad-supported; removing ads requires the Elite subscription. Personal Trainer shows no ads on the free tier or after the VIP unlock. Which app handles progressive overload better? Personal Trainer automates it: each set gets a difficulty tag and the app proposes the next-session load rounded to plate increments. JEFIT records your history and shows previous numbers, and its training programs include planned progressions, but it does not adapt the next load from how your last set actually felt. Can I use JEFIT or Personal Trainer without an account? JEFIT requires an account and a connection on first launch. Personal Trainer starts logging immediately with no account wall; Google Sign-In is used for identity only and cloud sync stays optional. #### Related - Personal Trainer vs Strong → - Personal Trainer vs Hevy → - Best offline workout tracker apps 2026 → - Personal Trainer FAQ → - Best exercises per muscle group 2026 → - Barbell plate calculator → #### Try Personal Trainer free.
