Definition
Training volume is the total mechanical work performed, most commonly calculated as hard sets per muscle group per week. Research shows 10–20 hard sets per muscle per week is the sweet spot for hypertrophy. Below 10, growth is minimal; above 20, recovery often breaks down. Volume should increase over a training block and then drop during a deload.
Real questions
How many sets per muscle per week?
10–20 hard sets per week for most people. Start at 10, add 2 sets every 2–3 weeks, deload, then repeat.
Does warm-up volume count?
No — only work sets taken within 1–4 reps of failure count toward hypertrophy volume.
