Short answer
Around 10 challenging sets per muscle group per week is a practical reference in the 2026 ACSM recommendations for muscle growth, but it is not a universal optimum. Some people progress with less, and trained lifters may benefit from more if they recover well.
What does the latest volume research show?
A 2026 systematic review and meta-regression analysed 67 studies involving 2,058 participants. It found that more weekly set volume was generally linked to greater muscle growth, with diminishing returns: each additional set tends to contribute less than earlier sets.
That does not mean endless sets are optimal. Fatigue, session quality, recovery, injury risk and time still matter, and a population-level result cannot identify one perfect target for an individual.
What counts as a set for a muscle?
A direct set is a working set that deliberately targets a muscle, such as a biceps curl for biceps. An indirect set also challenges the muscle during another movement, such as triceps working during a bench press.
The 2026 analysis explored ways to account for indirect work. Its findings suggest that treating indirect work differently from direct work can matter, but there is no exact universal conversion for every exercise and person.
Start by logging your performed exercises and working sets accurately before trying to calculate an overly precise total.
What might 10 weekly sets look like?
These are simple scheduling examples, not research-tested prescriptions or promises of equal results.
| Sessions per week | Direct sets per session | Weekly direct sets |
|---|---|---|
| 2 | 5 + 5 | 10 |
| 3 | 3 + 3 + 4 | 10 |
| 4 | 2 + 3 + 2 + 3 | 10 |
The better schedule is usually one you can complete consistently with good technique. A 2019 frequency meta-analysis found no meaningful average hypertrophy advantage from higher training frequency when volume was equal.
Should beginners and experienced lifters do the same amount?
Not necessarily. New lifters can start with a manageable number of sets and build consistent habits. More experienced lifters may experiment with extra sets when progress slows and recovery is good. You should not force higher volume simply to reach a number.
The ACSM review emphasizes that consistency, personal needs and a sustainable plan matter more than unnecessary complexity.
How do you tell if you need more or fewer sets?
- Log a normal training week. Record exercises, working sets, repetitions and weight.
- Check the pattern. Compare the same lifts over several weeks instead of using a single personal record.
- Consider recovery. If effort, form and progress are deteriorating, assess sleep, food, schedule and fatigue before adding more sets.
- Change one thing at a time. If you are recovering and making no progress, a small change to volume, load, exercise selection or technique may be more useful than a dramatic increase.

Can LIFT track your weekly sets?
LIFT records sets, reps and weights and helps organize workout splits and review performance. It does not promise to calculate a scientifically exact hypertrophy dose for you, and its public iPhone release is still pending. See actual LIFT workout-tracking features.
