How Many Sets per Muscle Group per Week? A Training Volume Guide

"How many sets should I do?" is one of the most common questions in lifting, and one of the few with a reasonably clear, research-backed answer. The short version: count your hard sets per muscle per week, aim for about 10 or more, and adjust from there based on your progress.

Weekly volume targets

These ranges are starting points, not prescriptions. Experience bands vary from person to person, and your logbook tells you more than any table.

What the research says

More sets, more growth, up to a point. A 2017 meta-analysis by Schoenfeld, Ogborn, and Krieger pooled 15 studies and found a dose-response relationship between weekly sets and muscle growth. Each additional weekly set was associated with about 0.37% more muscle gain over the study periods. Within each study, the higher-volume groups gained significantly more muscle than the lower-volume groups, and a three-tier comparison (fewer than 5, 5–9, and 10+ weekly sets) showed a trend in the same direction.

The 2026 ACSM position stand agrees. Summarizing 137 systematic reviews covering more than 30,000 participants, the American College of Sports Medicine concluded that muscle hypertrophy was enhanced by higher volumes of 10 or more sets per week. For strength, it found that 2–3 sets per exercise and training at least twice a week worked well.

Limits and caveats. The 2017 analysis drew on 15 studies and had little data far above 10 weekly sets. Later research has explored higher volumes, but the returns appear to shrink as volume climbs, and the extra fatigue is real. More is not automatically better.

What counts as a "hard set"?

Set counts only work if the sets are productive. A hard set is:

• A working set, not a warm-up. Warm-ups are intentionally easy (see warm-up sets).
• Taken reasonably close to failure, roughly 0–3 reps in reserve. A 2024 analysis by Robinson and colleagues found muscle growth increased as sets ended closer to failure.
• Done with a load you can control through a full range of motion.

Ten sets at RPE 5 aren't the same stimulus as ten sets at RPE 8. If you're not sure how hard your sets are, our RPE and RIR chart will help you rate them.

How to count sets for each muscle

Direct sets are easy: three sets of curls is three biceps sets.

Indirect sets are trickier. Compound lifts train more than one muscle. A practical approach many coaches use is fractional counting:

Counting secondary work as half a set isn't exact, but it keeps you from either ignoring it or double counting it.

How to calculate training volume

There are two common ways to measure volume, and they answer different questions.

1. Weekly hard sets per muscle. This is the best tool for planning muscle growth.

Chest this week: 3 sets bench + 3 sets incline press + 3 sets dips = 9 hard sets

2. Volume load (tonnage). Weight × reps × sets. This is useful for tracking the total work done on an exercise over time.

Bench press: 80 kg × 8 reps × 3 sets = 1,920 kg

Volume load rewards both heavier weights and more reps, so it should trend upward as you apply progressive overload. It's less useful for comparing different exercises, because 1,000 kg of leg press isn't comparable to 1,000 kg of curls.

How to adjust your volume

Start near the low end of your range and let your results guide you:

• Numbers going up and recovering well? Keep going. Don't add volume you don't need.
• Stalled for 3–4 weeks while sleeping and eating well? Add 2–3 weekly sets for that muscle, often as one more set on an existing exercise.
• Numbers dropping, joints achy, always sore? You're likely over your recoverable volume. Cut sets by about a third for a week, then rebuild.

Change one thing at a time, and give each change a few weeks before judging it.

Spreading sets across the week

Twenty sets for one muscle in a single session usually means the last ten are low quality. Spreading weekly volume over two or more sessions keeps more of your sets productive. That's one reason splits like push pull legs run six days, or are paired with full-body or upper/lower days.

Tracking volume in ForgeLyte Lift

ForgeLyte Lift records every set with its weight, reps, and set type, so warm-ups stay separate from the working sets that count. Your history shows exactly how many sets each workout included. ForgeLyte Lift Pro adds a volume-over-time chart (weight × reps) and per-exercise trends, so you can see whether added sets are actually turning into more work and stronger lifts.
