How Long Should You Rest Between Sets for Muscle and Strength?

For most people, rest about 2 to 3 minutes between sets of big lifts like squats, presses and rows, and about 90 seconds to 2 minutes on smaller exercises like curls and raises. In a study of trained men, 3-minute rests built more strength and thigh muscle than 1-minute rests. Past roughly 90 seconds, extra rest seems to add little for muscle growth, so save your longest rests for your heaviest sets.

The short answer: 2 to 3 minutes on big lifts

Rest long enough to do your next set as well as your last one. For most lifters, that works out to:

• Big compound lifts (squat, deadlift, bench press, overhead press, rows): 2 to 3 minutes, and 3 to 5 minutes when the sets are very heavy (about 1 to 6 reps).
• Smaller single-joint exercises (curls, lateral raises, leg extensions): about 90 seconds to 2 minutes.
• Light, high-rep or circuit-style work: under 90 seconds is fine.

These ranges are guidance built from the research below, not the result of any single study. The studies explain why they make sense, and the table further down breaks them out by lift and goal.

What happened when trained lifters rested 1 minute vs 3 minutes?

The clearest head-to-head test is a 2016 study by Schoenfeld and colleagues.¹ Twenty-one young men with lifting experience were randomly split into two groups. One group rested 1 minute between sets and the other rested 3 minutes. Everything else was the same: three full-body workouts a week for 8 weeks, each with 3 sets of 8 to 12 reps on seven exercises.

After 8 weeks, the 3-minute group:

• gained significantly more one-rep-max strength on both the back squat and the bench press;
• added significantly more muscle thickness on the front of the thigh, measured by ultrasound;
• showed a trend toward more triceps growth, though it fell just short of statistical significance (p = 0.06).

Muscular endurance, tested as bench press reps at half of each man's max, improved in both groups by a similar amount.

Keep the limits in mind. This was one small study of 21 young, trained men over 8 weeks. It can't tell you how women, older adults or beginners respond, or what happens over a year or more.

Why does longer rest help?

The most likely reason is simple: you get more reps done. Rests of a minute or less noticeably cut the number of reps you can complete across several sets, and fewer total reps means less training for the muscle.²

A 2022 study put this to the test.³ Twenty-eight untrained young adults did knee extensions at 80% of their max, twice a week for 10 weeks. Each leg followed one of four plans:

• Legs that rested 3 minutes grew the quadriceps by 13.1%.
• Legs that rested 1 minute grew 6.8%.
• Legs that rested 1 minute but did extra work to match the 3-minute legs' total load grew 12.9%.
• Legs that rested 3 minutes but were held to the smaller workload grew 6.6%.

Strength gains were similar in all four. So rest isn't magic on its own. It's a way to protect the amount of work you get through. This was one exercise in untrained people, so treat it as a strong clue rather than a rule. How hard each set is matters too, which is covered in Do you need to train to failure?

Does the wider research agree?

Mostly, with caveats worth knowing.

For muscle growth, a 2024 Bayesian meta-analysis pooled 9 studies that compared rest lengths while keeping everything else the same.² Resting more than 60 seconds gave a small edge for growth in the arms and thighs. Resting more than about 90 seconds didn't show a clear further benefit. Most of the studies used younger, untrained people and lasted 5 to 10 weeks, and none measured chest, back or shoulder muscles.

For strength, a 2018 systematic review of 23 studies (491 people) found you can still gain strength with rests under 60 seconds.⁴ But trained lifters seemed to need more than 2 minutes to get the most from their training, while 60 to 120 seconds looked like enough for untrained people.

The big-picture view is more cautious. The American College of Sports Medicine's 2026 position stand pooled 137 systematic reviews.⁵ It found that short (under 1 minute) and long (over 1 minute) rests didn't consistently change strength gains, and that there wasn't enough data to judge their effect on muscle growth.

Put together: rest length probably matters less than total work and effort. But very short rests make it harder to get that work done, especially on heavy lifts.

How long should you rest? A practical table

Use this as a starting point. It's guidance, not a study result. It draws on the research above and on the ACSM's 2009 position stand, which suggested 3 to 5 minutes for heavy sets of 1 to 6 reps, 1 to 2 minutes for muscle-building sets, and under 90 seconds for light endurance work.⁶ Newer studies lean longer than 1 to 2 minutes for big muscle-building lifts, so the table does too.

Why 2 to 3 minutes on big lifts if growth seems to level off past 90 seconds? That 90-second finding came mostly from arm and thigh measurements in untrained people. For trained lifters on heavy compound lifts, more than 2 minutes looked better for strength,⁴ and 2 to 3 minutes has long been the mainstream recommendation.⁵ The authors of the 2024 meta-analysis also noted that more complex exercises may build up more fatigue across sets, so the right rest could differ from one exercise to the next.²

How do you know you've rested enough?

The clock is a guide, not a rule. A few practical checks:

• Ask if you're ready to match your last set. If you can hit your target reps with the same form, go. If not, wait a little longer.
• Watch your rep counts. If your reps drop sharply from set to set at the same weight, say 10, then 7, then 5, your rests are probably too short for that lift.
• Time your rests. A timer keeps rests consistent from week to week, so changes in your reps reflect your strength rather than a shorter or longer break. Rep Labs includes a rest timer alongside reps and weight planned from your training history.

What if you're short on time?

Long rests make workouts longer. A few ways to keep the benefits without living at the gym:

1. Spend rest where it counts. Keep 2 to 3 minutes for the big compound lifts and trim rests on small exercises.
2. Add a set instead of losing work. In the knee-extension study, 1-minute rests matched 3-minute rests for growth once the short-rest legs did enough extra work to equal the total load.³
3. Alternate exercises that use different muscles, like a press and a row. Each muscle rests while you keep moving. There's little research on this exact setup, so treat it as a practical workaround.
4. Drop an exercise before you cut rest on your main lifts if a session still runs long.

When does shorter rest make sense?

• Your goal is muscular endurance or conditioning. ACSM guidance uses rests under 90 seconds for light, high-rep work.⁶
• You're doing small, light isolation exercises. The 2024 meta-analysis found little added growth from resting past about 90 seconds.²
• You're new to lifting. In the 2018 review, 60 to 120 seconds seemed to be enough for untrained people to gain strength.⁴
• The set was easy, like a warm-up set. It doesn't need a full 3 minutes.

Rest longer than usual when you're lifting heavy, going for a rep record, or when your last set left you badly out of breath. If you're also choosing between barbells and machines, see Free weights vs machines.
