← All guidesRest Between Sets: How Long Should You Wait?
Rest is the training variable people decide by feel: you start the next set when your breathing settles. But how long you rest decides how many reps survive into your later sets — and those reps are what the session was for.

The short answer
Compound lifts for big muscles — squat, bench, row, deadlift — rest 2–3 minutes. Training for maximal strength at 1–5 reps, rest 3–5.
Isolation work for small muscles (curls, triceps, calves) is fine at 60–90 seconds. Less muscle mass to recover, and no systemic cost.
The 30–60 seconds of a circuit or a conditioning class is not a mistake, it is a different goal: you are training the ability to keep working while tired, not maximal force.
"Shorter rest works better" comes from a hormonal hypothesis that has since been abandoned. The real causal chain is: too little rest → fewer reps in the later sets → less total work → slower progress.
Do not time it by feel. Your breathing settles at about 40–60 seconds, and what you need is often three times that.
The question someone actually tested
A 2016 trial put 21 resistance-trained men through the same 8-week program — same lifts, same sets, same rep ranges. The one thing that differed was the gap between sets: one minute for one group, three for the other.
The three-minute group gained more maximal strength in both the bench press and the squat, and more muscle thickness in the triceps and quadriceps. Note the design: the program was matched, so both groups were prescribed the same work. Prescribed, not performed — the short-rest group could not complete it.
Rest does not build muscle. It decides how many reps are still there in your third and fourth set — which is the actual work the session did. A 2017 systematic review put it plainly: rest longer than 60 seconds is not harmful, and short rest compromises growth precisely when it cuts the volume you complete.
How long, by what you are training for
These ranges come from a review that pulled the inter-set rest literature together, and they match the consensus in strength and conditioning. They are orders of magnitude, not prescriptions to the second — telling 60 seconds apart from 3 minutes matters far more than choosing between 150 and 180.
What you are training
Rest
Why
Maximal strength (1–5 reps)
3–5 min
The nervous system and the phosphagen system both need the time; a minute cut here comes straight off the bar.
Hypertrophy, big compounds (6–12)
2–3 min
Enough to keep the reps in your later sets — this is the range the trial actually separated.
Isolation, small muscles
60–90 s
Less muscle involved, little systemic cost, faster to recover anyway.
Muscular endurance, circuits
30–60 s
Here the fatigue is the training stimulus, not something to get out of the way.
The myth worth clearing up
Short rest keeps your heart rate up and spikes metabolic stress and growth hormone, so you build more muscle and burn more fat.
Short rest does produce a sharper acute growth-hormone response — and that response does not translate into more muscle. The hypothesis that rested on it has been abandoned. If you want a cardiovascular stimulus, train for one; cutting rest in a lifting session buys it by making you lift less.
When shorter rest is the right call
Once the mechanism is on the table, the exceptions stop looking like exceptions. Wherever completing that particular set is not the point, a short rest costs you nothing:
A hard time cap. With 30 minutes, "rest less and finish the session" beats "rest properly and do half of it". Short rest trades quality for time; an exercise you never reached is worth zero.
Alternating lifts that do not compete (supersets). Between a set of rows and a set of squats, the upper body rests while the lower body works. Total session time drops without shortening either lift's actual rest.
Isolation work at the end. The curls or calf raises you finish on were never going to tax the whole system; 60 seconds is enough.
Conditioning and circuits. Here short rest is the training rather than a compromise on it. Watch whether your movement quality holds, not whether the load goes up.
Stop timing it by feel
This is where rest actually goes wrong: almost nobody times it. You wait until your breathing settles — about 40 to 60 seconds — and start the next set, which means every session quietly runs the short-rest protocol. A phone in your hand is worse in the other direction: you look up and three minutes have gone.
In Omini a rest is a Recovery interval in the sequence — as much a part of the plan as the lift. Write it into the preset and the voice calls the start and end of every one, so you neither watch the screen nor count.
Build it as one loop: the exercise interval, then a Recovery interval, with the repetition count set to your number of sets. 180 seconds of recovery for heavy strength work, 60 for isolation — set it once and every session runs it the same way.

Frequently asked questions
How long should I rest between sets?
For compound lifts aimed at muscle growth, 2–3 minutes. For maximal strength at 1–5 reps per set, 3–5 minutes. Isolation work on small muscles such as curls or calf raises is fine at 60–90 seconds, and circuits or muscular-endurance work deliberately run at 30–60 seconds. The distinction that matters is 60 seconds versus 3 minutes, not 150 seconds versus 180.
Is resting longer between sets actually better for muscle growth?
For compound lifts, yes. A 2016 trial followed 21 resistance-trained men through the same 8-week program, identical in exercises, sets, and rep ranges, with the inter-set rest set to either 1 minute or 3 minutes. The 3-minute group gained more maximal strength in the bench press and squat and more muscle thickness in the triceps and quadriceps. Because the program was matched, the difference came from the short-rest group being unable to complete the prescribed work.
Does short rest between sets build more muscle by spiking growth hormone?
No. Short rest does produce a larger acute growth-hormone response after training, but that response does not translate into more muscle, and the hypothesis built on it has been abandoned. A 2017 systematic review of inter-set rest found that resting longer than 60 seconds is not detrimental, and that short rest compromises hypertrophy specifically when it reduces the training volume you actually complete.
When is a short rest between sets the right choice?
When completing that particular set at full quality is not the point. That covers four cases: a hard time cap, where finishing the session beats resting properly through half of it; supersets that alternate muscles which do not compete, so each lift still gets its full rest; isolation work at the end of a session; and conditioning or circuit training, where the short rest is the training stimulus itself.
How do I time rest between sets without watching my phone?
Make the rest part of the plan instead of a judgement call. In Omini a rest is a Recovery interval in the sequence: build a loop of one exercise interval plus one Recovery interval, set the repetition count to your number of sets, and voice cues announce the start and end of every rest so you never watch the screen. Timing it by feel is what causes the problem — your breathing settles at around 40 to 60 seconds, well short of what compound lifts need.
