Most lifters grow well on 10 to 20 hard sets per muscle group per week. Here's what counts as a set, where to start, how to split the week, and when to add more.
September 24, 2026
For most lifters training for muscle growth, 10 to 20 hard sets per muscle group per week is the range to work in. Beginners do well near the bottom of it. Lifters with a year or more of consistent training usually need the upper half to keep progressing.
That number only means something once you know what it counts. It's one way of measuring training volume for a single muscle, and one of the most useful numbers to pull out of your log once you track your workouts. This page covers what counts as a set, how many to start with, how to split them across the week, when to add more, and a worked example.
Not every set counts toward the weekly number, and miscounting is the most common reason two lifters “doing the same volume” get different results.
It has to be a hard set. A hard set is one taken close to failure: roughly RPE 7 or higher, or three or fewer reps in reserve. Warm-up sets and sets stopped well short of your limit don't count. The full effort scale is in our RPE chart.
Compound lifts count partly for muscles they work indirectly. A barbell row is a back exercise, but your biceps work hard through the pull. Counting each row set as a full biceps set overstates your biceps volume, and counting it as zero understates it. The usual compromise is half a set. That's more than habit: a 2026 meta-regression of 67 studies compared all three ways of counting (full, half and none) and found the half-set method fit the data best (Pelland 2026). This page uses it throughout.
If you've trained consistently for less than a year, start at around 10 hard sets per muscle per week. The best-known meta-analysis on the question pooled 15 studies and found a graded dose-response: each extra weekly set was associated with slightly more growth, about 0.37 percentage points, and groups doing 10 or more sets per muscle tended to grow the most (Schoenfeld 2017). Ten is enough to grow well on and leaves room to add sets later.
With a year or more of training behind you, aim higher. A systematic review limited to young trained men (aged 18–35, at least a year of lifting) concluded that 12–20 weekly sets per muscle group may be the best standard recommendation (Baz-Valle 2022). Going past 20 sets helped the triceps but made no measurable difference for the quadriceps or biceps, so “more” doesn't apply equally to every muscle.
These are averages across groups of people, not a prescription. Sleep, stress, exercise choice and how hard you actually push each set all move where your own number sits in the range.
Once your weekly total is set, how you spread it matters less for muscle growth than most advice suggests. The same 2026 meta-regression found that with weekly volume held equal, the effect of training a muscle more often on growth was compatible with zero. Strength was different: it kept rising with frequency, with diminishing returns (Pelland 2026).
The practical reason to split, say, 14 weekly chest sets over two sessions is set quality. By the ninth or tenth hard set for one muscle in a single workout, fatigue is eating into your reps. Two sessions of 7 sets keep every set productive and add up to the same total. That's a coaching rule of thumb rather than a research finding, but it's why most programs train each muscle at least twice a week. Whether you get there with push/pull/legs, upper/lower or full body is a scheduling question, covered in PPL vs upper/lower vs full body.
Your weekly number isn't fixed. Two signals suggest adding a set or two per muscle:
Renaissance Periodization's Mike Israetel describes this as working between your minimum effective volume (MEV, the least that still produces growth) and your maximum recoverable volume (MRV, the most you can recover from). Add sets gradually. When joints start aching or performance drops from one week to the next, you're near your MRV, and that's the time for a deload week before pushing volume any further. Adding sets is a form of progressive overload too, alongside adding weight or reps.
Take biceps, aiming for about 10–12 hard sets a week across two pull sessions. Direct sets count as 1 and indirect sets as 0.5.
| Session | Exercise | Sets | Counts as | Biceps sets |
|---|---|---|---|---|
| Monday | Barbell row | 4 | Indirect (0.5) | 2 |
| Monday | Lat pulldown | 3 | Indirect (0.5) | 1.5 |
| Monday | Barbell curl | 3 | Direct (1) | 3 |
| Thursday | Pull-up | 3 | Indirect (0.5) | 1.5 |
| Thursday | Cable curl | 3 | Direct (1) | 3 |
| Weekly total | 16 | 11 |
That's eleven biceps sets for the week, and only six of them are curls. The same table works for any muscle: list the exercises that train it directly and the ones that work it indirectly, then add them up.
Search this question and you'll see 10–20, 12–20 and 20-plus all presented as the answer. Three things explain most of the spread. Sources count indirect sets differently (as full, half or zero). They generalise from different people, and Baz-Valle's 12–20, for example, comes from trained men, not beginners. And different muscles respond differently to very high volume (Baz-Valle 2022).
Sweatora logs weight, reps and an effort rating for every set. The one-tap ratings are recorded as RPE: Easy is 5, Good 7, Hard 8 and Max 10, so every set you rate Good or harder meets the hard-set line above. The app doesn't count weekly sets per muscle for you, so the count itself is manual: go through a week of your log and tally the Good-or-harder sets for each muscle, using the half-set rule for compounds.
What the Stats screen does show is your training volume (weight × reps) split by muscle group for any date range you pick. That's a different number from a set count, but it answers a related question quickly. If one muscle's share is far below the others, your program is probably neglecting it, and that's the muscle to count sets for first.
No. Warm-ups prepare your joints and rehearse the movement. They sit well below RPE 7, so they aren't hard sets.
The weekly target doesn't change. Full-body training spreads it over more, smaller sessions, often three a week, which keeps the number of sets per muscle in each session low.
No. Muscle growth and strength both keep rising with volume, but with diminishing returns, and the returns flatten sooner for strength than for muscle size (Pelland 2026). Past your recoverable volume, extra sets cost recovery without adding growth.
Any exercise where a muscle assists rather than doing the main work. Common examples are rows and pulldowns for the biceps, and the bench press and overhead press for the triceps and front delts. If you're unsure, count it as half a set. The error is small either way.
How to Track Workout Progress (and Use the Data to Get Stronger)
To track workout progress, log five things for every set, then use one simple rule to decide whether to add weight, keep it the same, or back off. Here's what to record, which numbers show real progress, and how to turn last week's log into this week's plan.

An RPE chart for lifting links how hard a set felt, how many reps you had left, and what percentage of your one-rep max that effort works out to. Here's the full chart, the formula behind every number, and how to use it.
