How Many Sets Per Muscle Per Week Do You Need to Grow?
Research points to roughly 10–20 hard sets per muscle group per week for most lifters. Here's what the evidence says, how to count sets properly, and how to tell if you're doing too much or too little.
By Rayyan Siddique, founder of RepEight
"How many sets should I do?" is one of the most common questions in lifting. The honest answer is a range, but it's a fairly well-researched one.
The short answer
For most people training to build muscle, around 10–20 hard sets per muscle group per week is a good target. Beginners can grow on less. Advanced lifters sometimes need the upper end.
What the research says
A 2017 meta-analysis by Schoenfeld, Ogborn and Krieger in the Journal of Sports Sciences looked at how weekly set volume related to muscle growth. It found a clear dose–response relationship: more weekly sets generally meant more growth, and 10 or more sets per muscle per week produced noticeably more hypertrophy than fewer than 5.
Later work has broadly agreed that volume matters, with diminishing returns as you go higher. The benefit of going from 5 to 10 sets is much bigger than going from 15 to 20.
What counts as a "set"?
This is where most people miscount. A set counts towards your weekly volume if it's:
- A working set, not a warm-up
- Reasonably close to failure, about 0–3 reps in reserve (RPE 7–10). See RPE vs RIR explained.
- Mainly working the target muscle. Bench press counts for chest. It also trains triceps and front delts, and many lifters count those as half a set.
Where to start
| Experience | Sets per muscle per week |
|---|---|
| Beginner (under 1 year) | 6–10 |
| Intermediate (1–3 years) | 10–16 |
| Advanced (3+ years) | 12–20+ |
Start at the bottom of your range. If you're recovering well and progress stalls, add 2–3 sets per week to the muscle that's lagging.
Spread it out
Splitting your volume across two or more sessions per week tends to work better than cramming it into one. Twelve sets of chest is easier to do well as two sessions of six than one session of twelve. That's one reason upper/lower and push/pull/legs splits are so popular.
Signs you're doing too much
- Your numbers go backwards for two or more weeks
- Joints ache more than muscles
- You dread sessions or sleep badly
- Sets later in the workout are much weaker than normal
If that sounds familiar, cut volume by about a third for a week. That's a deload.
Signs you're doing too little
- Sessions feel easy and you recover in a day
- A muscle isn't growing but everything else is
- You're making the same lifts for the same reps week after week
Track it, don't guess
Counting sets per muscle across a week of mixed exercises is tedious by hand. RepEight's muscle heatmap does it for you: every set you log adds volume to the muscles it works, so you can see at a glance which groups are getting 16 sets and which are getting 4.

FAQ
How many sets per muscle per week for hypertrophy?
Most lifters grow well on about 10–20 hard sets per muscle group per week. Beginners can progress on less, around 6–10, while some advanced lifters benefit from the upper end.
Do warm-up sets count towards weekly volume?
No. Only count working sets taken reasonably close to failure, roughly 0–3 reps in reserve.
Is 20 sets per muscle too much?
It can be for many people. If performance is dropping, joints ache or you can't recover between sessions, reduce volume. More only helps if you can recover from it.
