The short answer
| What you are doing | Rest between sets | Why |
|---|---|---|
| Heavy strength sets (1 to 6 reps) | 3 to 5 minutes | Strength grows most when every set is heavy |
| Big lifts for muscle (6 to 12 reps) | 2 to 3 minutes | You keep your weight and reps in the next set |
| Small exercises (curls, raises, extensions) | 1 to 2 minutes | Less muscle at work, so less to recover |
| New to lifting | 1 to 2 minutes | Lighter weights need less recovery |
| Short on time | 60 to 90 seconds, or pair exercises | Alternate two exercises for different muscles |
Rest long enough that your next set hits the reps you planned. Losing a rep by the last set is normal; if you lose more than that, rest longer.
Rest for strength vs muscle growth
Longer rest built more strength
In a 2016 study, 21 trained men followed the same full body plan for 8 weeks, resting either 1 minute or 3 minutes between sets. The 3-minute group gained more strength in the squat and bench press, and more muscle on the front of the thigh [1]. A 2018 review of 23 studies came to a similar view on strength: short rests still build it, but people who already train seemed to gain the most with rests longer than 2 minutes, while beginners did as well on 1 to 2 minutes [2].
For muscle growth (hypertrophy), the benefit levels off after about 90 seconds
A 2024 review pooled 9 studies on muscle growth. It found a small benefit to resting more than 60 seconds, and no clear extra benefit beyond 90 seconds [3]. The authors suggest volume may explain it: with too little rest you lift less weight for fewer reps in the next set, so each set does less work.
So the long rests that help strength most are not a must for muscle. They do no harm either, and on heavy compound lifts most people need them anyway to hit their reps.
How to tell if you rested long enough
- About right: you planned 3 sets of 8 and got 8, 8 and 7.
- Too short: 8, then 5, then 3. If the first set went to plan, the weight is fine; the rest is not.
- Ready to go: your breathing has settled and your grip feels fresh.
- Form holds: each set looks as clean as the first one did.
How to rest when you are short on time
- Pair exercises. Alternate two exercises that use different muscles, such as a press and a row. Each muscle still gets its 2 minutes while you keep moving.
- Rest longest where it counts. Give the first, heaviest lift full rest, and cut rest on the smaller exercises at the end.
- Do fewer, better sets. A few exercises with full rest beat many rushed ones. See how many exercises per workout.
- Time it. Rest by feel and it drifts from set to set. A timer keeps every session the same.
Common mistakes with rest between sets
- Rushing the big lifts. Short rest on squats and deadlifts costs you weight and reps, and your form slips when you are out of breath.
- Resting while scrolling. Two minutes on your phone easily turns into five.
- Treating rest as wasted time. Rest is part of the next set.
- Never changing it. Heavy weeks need more rest; lighter ones, like a deload week, need less.
Time your rest in the app
In Gym Commitment the rest timer starts on its own when you tick a set. It counts down on the card and on your lock screen, so the phone can stay in your pocket. Add or take off 15 seconds, or skip it. Last time's numbers sit in every set, so you see at once whether your reps are holding up.
Rest between sets FAQ
Is 1 minute rest between sets enough?
For small exercises and for beginners, often yes. For heavy compound lifts it is usually too short: you lift less in the next set. In a 2016 study of trained men, 3 minutes of rest built more strength than 1 minute.
Is 5 minutes rest between sets too long?
Not for heavy strength work. For sets of 1 to 6 reps close to your limit, 3 to 5 minutes is common. For muscle-building sets it is more than you need, and it makes sessions long.
Should I rest longer for strength or for muscle?
For strength. People who already train seem to gain the most strength with rests longer than 2 minutes. For muscle, the benefit levels off at around 90 seconds, though heavy compound lifts often need 2 to 3 minutes for you to hit your reps.
Do I need a rest timer?
You do not need one, but rest is easy to lose track of, especially with your phone in your hand. A timer keeps your rest the same from session to session, so your sets are comparable.
