Sets per muscle group
Working sets this week; 10–20 per muscle is the target range.
How to use it
- Enter each exercise you do this week: the muscle group it trains, its working sets across the whole week, reps and weight (0 for bodyweight), and use Add exercise for the rest. Weekly sets per muscle group is the primary variable driving hypertrophy — this calculator totals them and shows how far each muscle is from the range.
- Evidence-based volume ranges: 10–20 sets per muscle per week covers the effective range for most people (Schoenfeld, Ogborn & Krieger 2017). Below 10 sets a week is a low dose for most intermediates; above 20, returns diminish and recovery gets harder.
- Beginners respond to lower volumes (8–12 sets/week per muscle). Intermediate lifters need 14–18 sets/week. Advanced lifters may need 18–22+ sets/week. Volume should increase gradually across training years, not all at once.
- Higher training frequency (hitting each muscle group 2–3 times/week) outperforms equivalent-volume once-per-week training for hypertrophy. Distribute weekly sets across multiple sessions when possible.
- If progress stalls: add 2 sets per muscle group per week for 4 weeks, then reassess. If recovery degrades (soreness lasting >72 hours, declining performance), reduce volume rather than pushing through — overreaching delays progress more than it accelerates it.
Questions people usually ask
What is training volume?
Training volume is the total amount of work performed, typically measured as sets × reps × weight. It's a key driver of muscle growth and strength adaptation.
How many weekly sets per muscle group is optimal?
Research suggests 10-20 hard sets per muscle group per week for hypertrophy. Beginners benefit from the lower end, advanced lifters may need the higher end.
Does volume load matter more than number of sets?
Both matter. Set count is a better predictor of hypertrophy, while volume load (total weight) better tracks strength stimulus. This tool shows both.
Should I count warm-up sets?
No. Only count working sets taken close to failure. Warm-up sets don't contribute meaningfully to hypertrophy stimulus.
Is this tool free and private to use?
Yes. AI Fit Hub tools are free, no-signup browser tools. Inputs stay in your browser unless you choose to share a URL.
The formula, worked through
- Formula Workout Volume Formula
Workout volume formula: volume load = sets × reps × weight. Hard sets = total sets within 2 reps of failure per muscle group per week.
- Formula Junk Volume Threshold Formula
Junk volume: sets above MAV produce diminishing returns. Schoenfeld 2017 meta-analysis: ≥10 sets/muscle/week, plateau by ~20 sets. Above MRV is regression.
- Formula Progressive Overload Formula
Progressive overload formula: next-week target = current load × (1 + overload_rate). Typical 2.5% novice / 1.5% intermediate / 0.5% advanced.
