Short answer: most people should do 10 to 20 hard working sets per workout, spread across 4 to 8 exercises, with no more than about 6 to 10 hard sets for any single muscle in one session. Beginners do well at the low end. Experienced lifters chasing muscle growth can work at the high end. Warm-up sets do not count. Past roughly 10 sets for one muscle in a session, the extra sets mostly add fatigue, not growth.
I'm Pasha, founder of 1RM.fit. "How many sets should I do today" is a different question from "how many sets per week", and mixing them up is how people end up with 25 sets of chest on Monday and nothing for the rest of the week. This article is about the single session. If you want the weekly picture, read how many sets per muscle per week as the deeper dive.
How Many Sets Per Workout, by Experience and Goal
Find your row and use it as your starting point. These are hard sets, meaning sets taken within about 0 to 3 reps of failure. Easy warm-up sets are extra.

Strength sessions use fewer exercises because the main lifts take more sets and longer rests. Muscle-focused sessions add more exercises to hit each muscle from a couple of angles. Beginners grow on less volume, so more sets mostly add soreness and time.
The Per-Muscle, Per-Session Cap
The strongest evidence on volume is about the week, not the session. A 2017 meta-analysis by Brad Schoenfeld, Dan Ogborn and James Krieger found a dose-response relationship: more weekly sets per muscle produced more growth, and 10 or more weekly sets clearly beat fewer than 5. A 2019 study by Schoenfeld and colleagues on trained men compared 1, 3 and 5 sets per exercise, 3 times a week. The highest-volume group grew the most muscle, while strength gains were similar across all three groups.
What those studies do not give you is a hard number for one session. The 6 to 10 sets per muscle per session cap is a practical guideline, not a law. Coaches drew it from the same body of work: the weekly benefit appears when volume is spread across 2 or more sessions, and set quality drops fast once one muscle has taken 8 to 10 hard sets in a row. Sets 11 and 12 for your chest are usually done with fewer reps and less load, which is why they add more fatigue than growth.
So the rule of thumb is simple. If you need 16 weekly sets for a muscle, split them into two sessions of 8, not one session of 16.
A main lift like the bench press gets 3 to 4 hard sets. The rest of the chest budget goes to 1 or 2 other exercises.
Sets Per Workout by Split
Your split decides how many muscles share one session, which decides how the sets get divided. If you have not picked a split yet, the workout splits hub compares 3 to 6 day options side by side.
Full body (3 days per week)
Every major muscle in every session, so each one gets only 2 to 4 sets. Example: squat 3, barbell bench press 3, barbell row 3, Romanian deadlift 2, overhead press 2, curls 2. That is 15 sets across 6 exercises, and over 3 days most major muscles still land around 9 to 15 weekly sets.
Upper/lower (4 days per week)
Example upper day: bench press 3, row 3, overhead press 3, lat pulldown 3, lateral raises 3, curls 2, triceps pushdowns 2. That is 19 sets across 7 exercises. Chest gets 3 direct sets plus help from overhead pressing, back gets 6. Each muscle is hit twice a week.
Push pull legs (3 or 6 days per week)
The push day in our push pull legs routine is 20 sets across 6 exercises: 7 for chest, 7 for shoulders, 6 for triceps. That sits right at the top of the range, which works because each muscle only takes 6 to 7 direct sets.
Bro split (5 days per week)
One muscle per day, so a chest day can easily hit 16 to 20 chest sets. That is where the per-session cap bites. The first 8 to 10 sets do most of the work and the rest are done tired. A bro split can still build muscle, but you will usually get more from those sets by spreading them across two days.
How Long a Workout Takes
Set count is what really decides how long you spend in the gym. A working set takes about 30 to 60 seconds, and the rest after it takes 1 to 3 minutes. Budget about 2.5 to 3 minutes per hard set, plus 10 minutes of warm-up.
12 sets: about 40 to 45 minutes.
16 sets: about 50 to 60 minutes.
20 sets: about 60 to 70 minutes.
If you are short on time, do not cut rest on your heavy lifts. Use shorter rests on isolation work and pair non-competing exercises instead. The details are in how long to rest between sets.
Sets vs Reps: What Actually Counts
For muscle growth, count hard sets, not total reps. Research comparing heavy and light loads, including another 2017 meta-analysis led by Schoenfeld, found similar growth across a wide rep range when sets were taken close to failure. A hard set of 6 and a hard set of 15 count about the same toward muscle growth. The full rep range breakdown is in how many reps to build muscle.
Muscle growth: 3 sets of 6 to 15 reps per exercise is a reliable default.
Strength: more sets of fewer reps on the main lift, like 4 to 5 sets of 3 to 6, then lighter accessories.
Effort matters more than the exact number: a set stopped 6 reps short of failure barely counts. Sets taken to 0 to 3 reps in reserve are what drive growth, as covered in is training to failure necessary.
A hard set of 8 rows at 70 kg counts the same as a hard set of 12 at 60 kg. Both are one set.
Signs You Are Doing Too Many or Too Few Sets
Too many: your reps on the last exercise fall apart every session, your main lifts go backwards for 2 weeks or more, workouts regularly run past 90 minutes, joints ache, or you dread the session before it starts.
Too few: you finish in under 30 minutes with plenty left, your weights and reps have been flat for a month while sleep and food are fine, and you never feel a pump or any next-day fatigue in the target muscle.
Your logbook settles this faster than how you feel. If reps at the same weight keep climbing, your volume is working. If they are falling, cut sets before you add more.
How to Progress Volume
Add load and reps first. Going from 80 kg for 8 to 82.5 kg for 8 is progress without adding a single set.
Add sets only when you stall. If a muscle has been flat for 3 to 4 weeks and recovery is fine, add 1 to 2 sets per session for that muscle.
Respect the cap. If a muscle already gets 10 sets in one session, add a second session for it rather than an 11th set.
Deload. Every 4 to 8 weeks, cut your sets by about a third for a week, then build back up.
Track it. You cannot manage volume you do not count.
This is why 1RM.fit logs every set and adds up your weekly volume per muscle automatically. You can see in one place whether your chest got 8 sets or 18 this week, and whether that number came from two good sessions or one long grind.
FAQ
How many sets per workout to build muscle?
10 to 20 hard sets per workout for most people, with 6 to 10 sets for any one muscle. Beginners grow well on 9 to 15 sets. Advanced lifters may need up to about 25 if the sets are spread across several muscles.
How many exercises per workout should I do?
4 to 8 exercises. Beginners and strength-focused lifters do best with 3 to 5. Hypertrophy sessions for intermediate and advanced lifters often use 5 to 8 exercises at 2 to 4 sets each.
Is 20 sets per workout too much?
Not if the sets are spread across 3 or more muscles and you recover between sessions. 20 sets for a single muscle in one session is too much for most people, since quality drops sharply after about 10.
How many sets per muscle per session for hypertrophy?
About 6 to 10 hard sets. Below that, train the muscle more often to reach your weekly total. Above it, most extra sets add fatigue without adding much growth.
Is 3 sets per exercise enough?
Yes, for most exercises. 3 hard sets per exercise across 4 to 6 exercises lands you at 12 to 18 sets per workout, which is right in the effective range.
How many sets and reps should a beginner do?
2 to 3 sets of 8 to 12 reps per exercise, across 3 to 5 exercises, for 9 to 15 total sets. Focus on adding weight each week before adding sets.
