How Many Sets per Muscle Group per Week? Count Yours
How many sets per muscle group per week? 10–20 hard sets for most lifters. Count your own week, indirect sets as half, and see which muscles fall short.
Enough sets and still not growing? The diagnosis finds the real limit.
List what you do in a normal week. Count only hard sets: ones that end within about three reps of failure.

Pressing counts half a set for triceps and front delts, rows and pulldowns half for biceps and rear delts, squats half for glutes. Markers at 10 and 20 sets.

Most lifters grow best on 10–20 hard sets per muscle group per week. Fewer than 10 still builds muscle, just more slowly; past 20 the returns keep shrinking. Enter your normal week above: the calculator adds up every muscle, counts the sets that only train it indirectly as half, and shows which muscles fall short.
How many sets per muscle group per week do you need?
Ten or more hard sets per muscle each week is where the largest gains show up. A meta-analysis of 15 studies found each extra weekly set added about 0.37% more growth, with the best results at 10 or more (Schoenfeld et al., 2017). The 2026 ACSM position stand, built on 137 systematic reviews, lands on the same mark (ACSM, 2026).
That makes 10 a floor for any muscle you want bigger, not a target to stop at. If a muscle shows "Under 10" above and it is the one that refuses to grow, you have found the first thing to change.
How many sets per week should a beginner do?
Fewer: two or three sets per exercise, with each muscle trained two or three days a week, is enough in the first months. The ACSM progression guidelines start novices at one to three sets per exercise (ACSM, 2009). Beginners grow on almost any hard training; add sets once progress slows, not before.
How do compound lifts count toward weekly sets?
As half a set for the muscles that help. A bench press is a full set for the chest and half a set each for triceps and front delts; a row is a full set for the back and half for biceps. A meta-regression of 67 studies found this fractional count predicted growth better than counting every muscle fully (Pelland et al., 2026).
This is why arms are often lower than lifters think: rows and pulldowns help the biceps, but at half credit. If that sounds like you, read why biceps stop growing.
What counts as a hard set?
A set that ends within about three reps of failure, or three reps in reserve. Growth increased as sets ended closer to failure in a meta-regression of trained and untrained lifters (Robinson et al., 2024), but going all the way to failure added little over stopping just short (Refalo et al., 2023). Warm-ups and easy back-off sets do not count.
Are more than 20 sets a week too many?
Not by itself, but each set beyond 20 buys less. Muscle growth kept rising with volume across the 67 studies, while strength levelled off much sooner (Pelland et al., 2026). Above 20, check recovery: if performance drops for weeks, you are past what you can use. Read the signs of overtraining before adding more.
Does it matter how you split the sets across the week?
Mostly as a way to keep sets productive. Training a muscle twice a week beat once a week in a 10-study meta-analysis (Schoenfeld et al., 2016), but with total volume equal, frequency made little difference to growth. Twenty sets crammed into one session lose quality by the end; split them over two or three days.
If every muscle reads 10–20 and you still are not growing, sets are not the problem. Food, sleep and effort can cap all of it: find out which one is limiting you.
FAQ
Is 3 sets per exercise enough?
Yes, if the weekly total works out. Three sets of bench twice a week gives the chest 6; add a fly or incline press to reach 10.
How many sets per week to maintain muscle?
Far fewer. Young adults kept their gains on one-third, and even one-ninth, of their original training volume for 32 weeks (Bickel et al., 2011).
Do warm-up sets count?
No. Count only sets that end within about three reps of failure.
How many sets for arms per week?
The same 10–20 as other muscles, counting rows and presses as half. Most lifters need a few direct curl and triceps sets to get there.
