How Long to Rest Between Sets for Hypertrophy
For muscle growth, rest about 2 minutes between sets of isolation exercises and about 3 minutes between sets of heavy compound lifts. In two trials, resting 1 minute between sets grew the thighs less than resting 3 minutes. In one of them, extra work to make up the lost reps closed the gap.

A 2024 meta-analysis found a small, uncertain benefit from resting more than 60 seconds and no appreciable extra benefit beyond 90 seconds for arm and thigh growth (Singer et al., 2024). Most of its studies used untrained people and none measured the chest or back. GainsLog's position, from Ossian's research notes, is to rest at least 2 minutes, and its default rest timers use 2 and 3 minutes. If you're short on time, pair opposing muscles or add a set rather than only cutting rest.
Rest times by exercise
These are starting points based on the studies below.
| Situation | Rest | What the studies found |
|---|---|---|
| Isolation exercisesCurls, lateral raises, machine flies, leg extensions | About 2 min | On a machine fly at 3RM loads, 2 min kept more total reps than 1 min |
| Heavy compound liftsSquats, bench press, rows, leg press | About 3 min; 3-5 min for near-max sets | On bench press at 3RM loads, only 3 and 5 min kept more total reps than 1 min |
| Short on time | Pair opposing muscles, or add work if you cut rest | Supersets kept volume in less time; 1 min rest with matched volume grew about as much as 3 min |
| 1 minute or less as a default | Avoid | 1 min grew the thighs less than 3 min in two trials |
Rest length changes how many reps you get
Rest seems to affect growth mainly through the work you can do in the sets that follow. Rest too little and your second and third sets lose reps, or you have to drop the weight.
Longo and colleagues tested this directly. Twenty-eight people trained knee extensions at 80% of their one-rep max for 10 weeks, with each leg assigned to one of four protocols. With 3 minutes of rest, the quadriceps grew 13.1%; with 1 minute, 6.8%. When the 1-minute leg did extra work to match the 3-minute leg's volume load (weight times reps), it grew 12.9%. When the 3-minute leg's volume was cut to match the 1-minute leg, it grew 6.6% (Longo et al., 2022). In this study, the amount of work mattered more than the rest interval.
In trained men, Schoenfeld and colleagues compared 1 and 3 minutes of rest over 8 weeks of three full-body sessions a week, 3 sets of 8-12 reps to a repetition maximum on 7 exercises. Both groups did the same sets. The 3-minute group gained more thigh muscle thickness and more squat and bench press strength, with a trend toward more triceps growth (Schoenfeld et al., 2016).
The training volume guide counts volume in hard sets. Too little rest doesn't remove sets, but each set has fewer reps and less weight lifted in it.
Does resting longer than 3 minutes help?
For arm and thigh growth, probably not by much. Singer and colleagues pooled 9 studies with 19 measurements. Resting more than 60 seconds showed a small, uncertain benefit, perhaps because it kept volume load up, but the analysis found no appreciable difference beyond 90 seconds (Singer et al., 2024).
The studies have limits. Most used untrained, younger participants and ran 5 to 10 weeks; only 3 of the 9 used trained participants, so the analysis says less about trained lifters. None measured torso muscles such as the chest or back, though the authors think those are unlikely to respond differently.
Senna and colleagues had trained men do 5 sets at a 3-rep-max load. On the machine chest fly, 2, 3 and 5 minutes of rest all gave more total reps than 1 minute. On the bench press, only 3 and 5 minutes did better than 1 minute, and 5 minutes beat 2, but 5 minutes did not beat 3. Reps still fell across the five sets with every rest length (Senna et al., 2016). Those were near-maximal loads, heavier than most hypertrophy sets, but the pattern supports giving big lifts more rest than small ones.
The cost of resting longer is time. If 3 minutes on every set of curls makes you skip sets, a shorter rest is the better choice.
Short on time? Pair opposing muscles or add a set
Before cutting rest, try pairing exercises for opposing muscles: a set of rows, then a set of bench press, then back to rows. A 2025 meta-analysis of 19 studies found that supersets gave similar reps and volume load to traditional sets in less time, and the two studies in it that measured muscle growth found it similar. Agonist-antagonist pairs, such as chest with back, let people complete more reps than traditional sets, while pairing two exercises for the same muscle lowered volume load (Zhang et al., 2025). Supersets also felt harder.
A change of split is the other option. If every session is too long, fewer exercises per session and one more session a week can fit the same sets with full rest. The guide to training frequency covers how to spread sets across the week.
If you do cut rest, make up the reps you lose with extra work, for example an extra set. In the Longo study, the 1-minute leg that did extra work to match the volume load grew about as much as the 3-minute leg (Longo et al., 2022).
Why older advice said to rest less
Advice to rest briefly for size was based mostly on hormone responses. Rest under a minute can raise growth hormone after a workout, so short rest was assumed to build more muscle. A 2014 review found the link between those short-term hormone spikes and long-term growth weak. Of the long-term studies it reviewed, none found more growth with shorter rest, and one found more with longer rest (Henselmans and Schoenfeld, 2014).
According to the 2024 meta-analysis, the National Strength and Conditioning Association recommends 30 to 90 seconds for hypertrophy. Its authors wrote that their findings are inconsistent with that range and that rest guidelines for hypertrophy warrant reconsideration (Singer et al., 2024). The American College of Sports Medicine's 2009 position stand recommended 1 to 2 minutes for hypertrophy sets of 6-12 reps (ACSM, 2009).
Check your rest against your log
This is a practical rule, not a study result. Reps drop across sets even with long rest, as in the Senna study. Compare how much they drop with your usual pattern for that exercise. If later sets start losing clearly more reps than usual at the same weight and effort, rest longer. Keep rest similar from week to week so the numbers stay comparable, the same way you would to track progressive overload.
In GainsLog, a rest timer starts automatically when you mark a set done: 3 minutes after a compound exercise and 2 minutes after an isolation exercise. With Premium you can set your own defaults for each, between 1 and 5 minutes.
Short rest is not the only reason later sets come up short. If you stop sets at different distances from failure, the reps won't compare either. The guide to RIR and training to failure explains how hard each set should be.
