How Many Sets Per Muscle Group Per Week?
July 10, 2026 · 6 min read · Buffro Team
The research keeps landing in the same zone: most muscles grow best on about 10-20 hard sets per week. Under 10 and growth is slow; past 20 and most people just accumulate fatigue. Here's how to actually use that.
What counts as a set
- A hardset — taken to within 1-3 reps of failure. Warm-ups don't count.
- Compound lifts count for the secondary muscle too, at roughly half value: a set of bench is a full set for chest and about half a set for triceps.
- A set of rows is a full back set and roughly half a biceps set.
Per-muscle targets
| Muscle | Sets/week | Notes |
|---|---|---|
| Chest | 10-16 | Presses + flys; count incline separately from flat |
| Back | 12-20 | Rows + pulldowns; back handles volume well |
| Shoulders (side/rear) | 10-16 | Presses mostly hit front delts — raises do the rest |
| Quads | 10-16 | Squats, presses, extensions |
| Hamstrings/glutes | 8-14 | Hinges + curls; deadlifts are fatiguing, count them honestly |
| Biceps | 8-14 | Half arrives free with back work |
| Triceps | 8-14 | Half arrives free with pressing |
| Calves & abs | 8-12 | Direct work or they don't grow |
Start low, earn more
Start at the bottom of each range. If you're recovering well and progress is steady after 4-6 weeks, add 2-3 weekly sets to the muscles you care about most. If sleep is bad or sessions drag past 90 minutes, cut volume — more isn't working.
Splitting it across days
Volume works better spread out: 14 chest sets as 2 × 7 beats one 14-set chest day, because late sets in a marathon session are junk. Any split that hits each muscle twice a week — 6-day PPL, upper/lower, or full-body — handles this automatically. Pick the split that fits your week.
