Do sets or reps come first?

Do sets or reps come first? Reps come first. You perform a set number of reps (repetitions) to complete one set, and then you rest before doing your next set. Think of reps as the individual movements and sets as the groups those movements come in. If your program says “3 sets of 10 reps” on bench press, you do 10 reps, rest, do 10 more, rest, and do 10 more. That is 3 sets of 10 reps and 30 total reps.

This matters because the number of reps and sets you choose changes what your body gets out of the workout. Get the balance wrong and you train for the wrong goal. Get it right and you build muscle, gain strength, and avoid wasted time in the gym.

What is a rep?

A rep is one complete movement of an exercise from start to finish. One squat down and back up is one rep. One bicep curl up and down is one rep.

Reps measure how many times you move the weight in a single stretch before you stop and rest. The number of reps you do tells your body what to adapt to. Low reps with heavy weight build strength. Higher reps with lighter weight build muscle size and endurance.

A 2021 study published in the Journal of Strength and Conditioning Research found that muscle growth was similar whether people did sets of 4, 8, or 12 reps, as long as total training volume was the same. This tells us reps are flexible, but you still need to work hard enough to challenge the muscle on each set.

What is a set?

A set is a group of reps done without stopping. When you finish your reps and put the weight down to rest, you have completed one set.

Most workout programs use between 2 and 5 sets per exercise. Guidelines published in the Journal of Strength and Conditioning Research (2019) recommend 2 to 3 sets per exercise for most people. Harvard Medical School agrees and suggests beginners start with 2 sets, then add a third as they get stronger.

The number of sets you do per muscle group each week is one of the biggest factors for muscle growth. A 2017 meta-analysis by Dr. Brad Schoenfeld found a clear relationship between weekly set volume and muscle gains, with at least 10 sets per muscle group per week producing better results than 5 or fewer sets.

How many reps should you do for muscle growth?

For muscle growth, aim for 6 to 12 reps per set. This rep range, done with a weight that is about 60% to 80% of your one-rep max, creates the best environment for muscle fibres to break down and rebuild bigger.

A 2019 systematic review published in the International Journal of Environmental Research and Public Health confirmed that 6 to 12 reps is the sweet spot for hypertrophy (muscle growth). The American College of Sports Medicine backs this up, recommending 1 to 3 sets of 8 to 12 reps at 70% to 85% of your one-rep max for beginners.

A 2024 study on women’s strength training confirmed what earlier research found in men. The 8 to 12 rep range with moderate to heavy loads produced real gains in both strength and muscle size.

But here is where it gets interesting. Research shows you can build muscle across a much wider range than most people think. A 2017 meta-analysis found that as long as you push hard enough, reps anywhere from 5 to 30 can produce growth. A study in the Journal of Applied Physiology found that people lifting lighter weight for 20 to 25 reps gained similar muscle to those lifting heavier for 8 to 12 reps. The catch was both groups had to push to the point where they could not do another rep.

So the rep range matters less than the effort you put in. But 6 to 12 reps remains the most time-efficient way to grow muscle for most people.

How many reps build strength?

For pure strength, train in the 1 to 5 rep range with heavy weights, about 80% to 100% of your one-rep max.

A review published in PMC (National Library of Medicine) found a clear dose-response relationship between load and strength gains. People training in the 1 to 5 rep range gained more one-rep max strength than those training in the 8 to 12 rep range. The review noted this becomes even more true the longer you train. As you get closer to your strength ceiling, heavier loads become more and more necessary.

When you lift heavy for low reps, you train your nervous system to recruit more muscle fibres at once. This is called neural adaptation and it is the main driver of strength in the early months of training. Rest periods matter here too. You need 2 to 5 minutes between sets when training for strength because your nervous system needs time to recover.

A 2024 meta-regression from SportRxiv found that for strength, the most effective volume was around 2 to 4 sets per muscle group per week. Past about 4 or 5 sets per week, additional strength gains were too small to reliably measure. This means strength training does not require high volume, it requires high intensity.

How many sets per week do you need for muscle growth?

For muscle growth, aim for 10 to 20 sets per muscle group per week.

A large 2024 meta-regression by Pelland and colleagues analysed 67 studies with over 2,000 participants. They found that muscle growth increases as weekly volume goes up, but with diminishing returns. The minimum effective dose was about 4 sets per muscle group per week for measurable growth. The sweet spot appears to be somewhere in the 12 to 20 set range per week per muscle group.

A separate 2022 systematic review found that going beyond 20 sets per week did not produce significantly more growth than sticking to 12 to 20 sets for most muscle groups. So more is not always better. Past a certain point, extra sets just add fatigue without adding muscle.

Here is how this works in practice. If you train chest twice per week and do 4 exercises of 3 sets each across those two sessions, that is 12 total sets for chest. Right in the effective zone.

What is double progression and why does it matter?

Double progression is the most practical way to use reps and sets together to keep getting stronger over time.

Here is how it works. You pick a rep range, say 8 to 12. You start with a weight you can lift for 8 reps with good form. Each session, you try to add one more rep. When you can do 12 reps on all your sets with that weight, you increase the weight by 2.5 to 5 kg and drop back down to 8 reps. Then you build up again.

This system uses both variables, reps and weight, to force your muscles to grow. You progress first in reps (volume) and then cash in that progress by increasing weight (intensity).

This matters because your body adapts fast. If you bench press 60 kg for 3 sets of 10 reps every single week, your muscles have no reason to grow after the first few weeks. They have already adapted to that workload. You need to give them something new.

A simple math example shows why. If you curl 20 kg for 10 reps, you have moved 200 kg in that set. If next week you curl 20 kg for 11 reps, you have moved 220 kg. That extra 20 kg of volume is a new stimulus for growth without needing to touch a heavier weight.

Once you can get to 12 reps on all sets, bump the weight to 22.5 kg and go back to 8 reps. Now you are lifting heavier and the cycle starts again.

Should you increase reps or add more sets first?

Increase reps first, then add weight. Only add more sets if you stop making progress with reps and weight.

Here is the order of priority when you want to keep progressing:

1. Add more reps with the same weight (double progression)
2. Add more weight when you hit the top of your rep range
3. Add more sets per exercise if progress stalls
4. Slow down your reps (tempo training) for a new stimulus
5. Improve your range of motion and technique

Adding sets is a powerful tool but it taxes your body more than adding reps. Research shows doing at least 10 sets per muscle group per week nearly doubles the gains compared to doing just 5 sets. But once you get into the 20 to 30 set range per week, returns drop off and fatigue climbs. A good rule is to increase volume by no more than 10% to 20% per week.

If you are currently doing 10 sets of chest per week and progress stalls, try adding one extra set to each exercise the following week. Keep doing that until you reach 20 to 25 total sets, then cycle back down to your original volume and start again.

Do beginners need the same sets and reps as advanced lifters?

No. Beginners grow with less volume and can add weight faster than advanced lifters.

If you are new to lifting, your body responds to almost any stimulus. You can start with 2 sets per exercise in the 10 to 12 rep range with a weight that feels challenging but doable. Harvard Medical School recommends beginners use enough weight so the last 2 reps feel tough but you still have 1 or 2 reps left in the tank.

Beginners can add 2.5 to 5 kg to the bar every week on big lifts like squats, bench press, and deadlifts. This straight-line progression works well for the first 6 to 12 months.

Advanced lifters need more volume and more creative progression methods. Studies show that when training experience goes up, you need to train closer to your one-rep max to keep gaining strength, and you need higher weekly set volumes to keep building muscle.

A study found that advanced trainees doing low volume training (1 to 2 hard sets per exercise) can maintain muscle mass even in a calorie deficit. But to build new muscle, they need higher volume. The research shows dropping to even one-ninth of your normal training volume is enough to maintain what you have built, but not enough to grow.

How long should you rest between sets?

Rest 60 to 90 seconds for muscle growth and 2 to 5 minutes for strength.

Your rest period depends on your goal. For hypertrophy work in the 6 to 12 rep range, shorter rests of 60 to 90 seconds keep metabolic stress high, which helps trigger muscle growth. For heavy strength work in the 1 to 5 rep range, your nervous system needs 2 to 5 minutes to recover so you can lift heavy again.

Research on cortisol and recovery suggests keeping your total workout, including warm-up, to about 60 to 70 minutes. Past 60 minutes of hard training, cortisol starts to climb and can slow recovery.

If you are short on time, supersets (doing two exercises back to back for different muscle groups) can cut your workout time in half. A 2024 study published in the Journal of Strength and Conditioning Research found that superset training produced nearly the same strength and muscle gains as traditional training while taking about half the time.

How do muscle fibre types affect your rep choices?

Different muscles respond better to different rep ranges based on their fibre makeup.

Type I (slow-twitch) muscle fibres resist fatigue and respond well to higher reps. Your calves, upper back, and postural muscles tend to have more Type I fibres. Training these muscles with sets of 12 to 20 reps or more can produce better results.

Type II (fast-twitch) muscle fibres generate more power and respond well to lower reps with heavier loads. Your quads, hamstrings, and chest tend to have more Type II fibres. Training these with sets of 6 to 10 reps with heavier weight targets these fibres best.

Muscles like your shoulders (deltoids) have a more even split of both fibre types and benefit from a mix of rep ranges.

This is why periodization works so well. Training in the 4 to 8 rep range for 3 to 4 weeks with 3 to 4 sets per exercise and longer rests, and then switching to the 8 to 15 rep range for the next 3 to 4 weeks with 2 to 3 sets and shorter rests, hits both fibre types over time.

How much does all this cost?

You do not need expensive equipment to use these principles. A basic gym membership in Australia runs about $15 to $30 AUD per week. A set of adjustable dumbbells for home training costs around $150 to $400 AUD and covers most exercises for beginners. Resistance bands start at about $20 to $50 AUD for a full set.

If you want a structured program, online coaching runs between $50 and $200 AUD per month depending on the level of personalisation. Many free programs based on double progression are available online and work well for beginners and intermediate lifters.

FAQ

1. Do you count reps or sets first when working out? You count reps first. Each rep is one movement. When you finish all your reps, that completes one set. Then you rest and start your next set.

2. What does 3 sets of 12 reps mean? It means you do 12 repetitions of the exercise, rest, do 12 more, rest, and do 12 more. That is 3 sets. You have done 36 total reps.

3. Is it better to do more sets or more reps? For muscle growth, doing more sets per week (up to about 20 per muscle group) produces better results than just adding reps to existing sets. But if you are already doing enough sets, adding reps through double progression is the easiest way to progress each session.

4. Can you build muscle with high reps and light weight? Yes. Research shows that reps up to 30 can build muscle as long as you push close to failure. A study in the Journal of Applied Physiology confirmed this. The weight matters less than the effort.

5. How many sets should a beginner do per workout? Start with 2 to 3 sets per exercise and 6 to 12 exercises per workout. This gives you about 12 to 36 total sets per session. Spread across the week, aim for 10 to 12 sets per muscle group.

6. What rep range burns the most fat? No specific rep range burns more fat than another. Fat loss comes from eating fewer calories than you burn. Any rep range that builds or maintains muscle while you eat in a calorie deficit will help you lose fat. Research shows exercise improves insulin sensitivity and inflammation markers even without weight loss.

7. How often should you change your rep range? Every 3 to 4 weeks works well for most people. Rotating between heavier, lower-rep phases and lighter, higher-rep phases prevents boredom and targets both muscle fibre types. This approach is called periodization and research supports it for long-term progress.

8. Is training to failure necessary for muscle growth? Not every set. Research suggests leaving 1 to 2 reps in the tank on most sets is enough to stimulate growth while managing fatigue. Going to failure on your last set of each exercise can help push growth further without burning you out. Studies show that most people underestimate how many reps they have left, so if you think you have 2 reps left, you may actually have 5 or more.

9. How do you know when to increase weight? When you can hit the top of your rep range on all sets with good form, increase the weight by the smallest amount possible (usually 2.5 kg for upper body and 5 kg for lower body exercises). If you drop below the bottom of your rep range with the new weight, that is normal. Build back up.

10. What happens if you do too many sets? Your performance drops, recovery suffers, and your workouts get longer without extra benefit. Research shows diminishing returns beyond about 20 sets per muscle group per week for most people. If you feel constantly sore, tired, or your strength is going backwards, reduce your volume by 30% to 50% for a week (a deload) and then build back up.
