Log your sets, reps, and weight per muscle group. The calculator aggregates your weekly volume and charts whether it's trending up — the clearest signal that progressive overload is happening.
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.

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.
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.
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.
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.
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.
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.

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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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).
Most lifters who feel they're training hard but not progressing are making one of these errors. The volume chart usually makes them obvious.
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.
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).
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.
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.
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.
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.
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.
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.
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.
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.
Personal Trainer logs your sets, calculates volume per muscle group, and suggests next-session loads — all offline, no subscription.
