How long to rest: a starting point
| Type of set | Rest |
|---|---|
| Heavy compound sets of 5 reps or fewer (squat, bench press, deadlift) | 3–5 min |
| Compound sets of 6–12 reps | 2–3 min |
| Isolation exercises (curls, lateral raises, triceps extensions) | 1–2 min |
| Light warm-up sets | As long as it takes to change the plates |
The ACSM recommends at least two to three minutes for heavy core exercises and one to two minutes for lighter assistance exercises. [1] The heavier the set and the more muscles it involves, the longer you need before you can repeat it. Setlane’s rest timer starts at two minutes by default, which suits most compound work; the heavy lifts and the small isolation exercises are the ones worth changing.
Does shorter rest build more muscle?
Not by itself. Short breaks feel productive because of the burn and the heavy breathing, but muscle grows from the work you do with enough effort, and short rest cuts the reps you can do on the following sets.
A 2024 meta-analysis found slightly better muscle growth on average with rests longer than 60 seconds. [2] A study in trained men saw more growth and more strength with three-minute rests than with one-minute rests. [3] For strength the case is even simpler: longer rest lets you keep the weight up on every set.
Why the same weight can produce fewer reps
Two bench press sessions at 60 kg:
- Session A: 10, 8 and 7 reps with 60 seconds between sets, 25 reps in total.
- Session B: 10, 10 and 9 reps with 180 seconds between sets, 29 reps in total.
Session B looks like a better workout, but most of the difference is the rest. If you compared it with session A and called it progress, your log would be misleading you. Keep rest roughly the same for an exercise from week to week; then a change in reps reflects your strength rather than the clock.
When to rest longer or shorter
Rest longer when
- your reps drop by more than two from one set to the next;
- your technique breaks down on the last reps before the set is truly hard;
- you are still breathing too hard to brace properly;
- you are doing heavy sets of one to three reps.
Rest less when
- the exercise is a small isolation or machine movement that barely tires the rest of your body;
- you are ready before the timer ends and your reps hold from set to set;
- you are short on time. Pair exercises that do not compete, such as rows and the bench press, in a superset instead of cutting rest on everything.
Warm-ups, supersets and drop sets
Light warm-up sets need almost no rest; give the last warm-up a minute or two before the first working set. In a superset, you move straight from one exercise to the next and rest after the round. In a drop set, the short pause is only for lowering the weight, and the normal rest comes after the whole chain.
Use the automatic rest timer in Setlane
When the timer is on, logging a set starts the rest countdown. It stays visible while you move around the workout, and rest notifications also arrive with the screen locked when the phone allows them.
Set different rest times for different exercises
- Open Settings, then Rest timer. Turn on the timer and choose a default duration.
- Under Rest by exercise, choose Add exercise. Select the exercise, set its duration and save it.
- Give your heavy lifts a longer time and the small exercises a shorter one; everything else keeps the default. These settings are included in Free.
If you do not hear an alert, check the timer’s sound and notification settings and the phone’s permissions.
Frequently asked questions
Is 60 seconds of rest enough for muscle growth?
For isolation exercises, often yes. For heavy compound lifts, usually not: you lose reps on the later sets. If your reps drop sharply after a minute, give that exercise two to three minutes.
Can I rest longer than three minutes?
Yes. Three to five minutes is normal for heavy sets of five reps or fewer. A long rest is not wasted time if it lets you lift the weight you planned.
Does resting longer mean I am making less progress?
No. The workout takes longer, but you usually complete more reps with the same weight. Keep the rest similar from week to week so you compare like with like.
Is Setlane’s rest timer free?
Yes. The automatic rest timer and rest times for each exercise are available on Free. Notifications depend on your app and phone settings.
