Workout Volume Calculator
Calculate total weekly training volume (sets × reps × weight) and compare against optimal hypertrophy ranges per muscle group.
Result
Sets per muscle group
Optimal hypertrophy range is 10–20 working sets per muscle per week.
How to use it
- Enter each muscle group trained, sets per session, and sessions per week. Weekly sets per muscle group is the primary variable driving hypertrophy — this calculator makes that visible.
- Evidence-based volume ranges: 10–20 sets per muscle per week covers the effective range for most people. Below 10 sets/week is below minimum effective dose for most intermediates. Above 20 sets/week yields diminishing returns and elevated injury risk.
- 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?
