Rest Periods: How Long Should You Rest Between Sets?

If you wait exactly 60 seconds after every set, you are not automatically training “better for muscle growth”.

And if you rest five minutes between every curl, you are probably not using your time particularly well either.

The right rest period is not a fixed value for the whole workout. It has a job:

You should recover far enough that the next set still delivers the training stimulus you planned.

How long that takes depends above all on the exercise, the load, the rep count, your proximity to failure and your training goal.

Why rest periods make a difference at all

After a hard set, your short-term capacity drops.

Local fatigue in the muscle, reduced availability of high-energy phosphates, breathing and circulatory load and central factors all contribute to your managing fewer reps in the next set.

The shorter the rest, the stronger that effect can be.

A simple example:

You bench press with a weight that allows 10 clean reps in the first set.

With a very short rest, the sequence might look like this:

10 / 7 / 5

With a longer rest, perhaps:

10 / 9 / 8

The longer rest did not build muscle directly here. It let you complete more high-quality work at the same load.

Which is exactly why rest periods can become relevant over the long run.

What the current research says about hypertrophy

For a long time the common recommendation was:

• 30–60 seconds for muscle growth
• 3–5 minutes for strength

The logic behind it: short rests create more metabolic stress and “pump”, so they must produce more muscle growth too.

Today’s data is more nuanced.

A Bayesian meta-analysis from 2024 pooled nine controlled studies. The result:

• Rests over 60 seconds showed a small advantage for hypertrophy on average over very short rests.
• Above roughly 90 seconds, no clear additional hypertrophy advantage was detectable.
• The uncertainty between studies was relatively large.

Which matters, because what follows from it is not:

For hypertrophy you always have to rest 2–3 minutes.

But rather:

Very short rests can cost performance unnecessarily. Beyond that, the optimal rest is increasingly determined by the specific exercise and how your sets are going.

The 2026 ACSM position stand also arrives at the broader conclusion that many details of training prescription have smaller effects than is often assumed. So rest periods should not be looked at in isolation.

Why the exercise changes the rest

Ten reps of lateral raises and five heavy squats can both be “RPE 9”.

Even so, you probably do not need the same recovery time afterwards.

Heavy multi-joint exercises

Squats, deadlifts, bench press, heavy rows and overhead press do not load only a single target muscle.

The heavier and more systemically demanding the set, the more several minutes of rest makes sense.

A practical range:

roughly 2–5 minutes

That is no biologically compulsory span. A heavy set of three squats can justify five minutes. A moderate set of ten on the chest press perhaps considerably less.

Lighter isolation exercises

On curls, lateral raises, triceps pushdowns or calf raises, the systemic load is usually smaller.

In practice these are often enough:

roughly 1–2 minutes

If you get back to the same rep quality after 60 seconds, you do not have to wait longer on principle.

If your reps drop sharply from set to set, more rest is one of the first variables you can test.

Recommendations by goal

Instead of a rigid table saying “hypertrophy = exactly 2–3 minutes”, this orientation is more useful:

The range is a starting point, not a test you have to pass to the second.

Compound vs. isolation: same rule, different need

The basic rule always stays the same:

The rest is long enough when the next set can still do what it is supposed to do.

On a heavy set of squats, that might mean you are still breathing hard after three minutes and would rather wait another minute.

On a set of curls, 75 seconds can be entirely sufficient.

Which is also why blanket rest times per training goal are less useful than rest times per exercise and set type.

Between warm-up sets, the rest can also be considerably shorter, as long as the next set is not limited by residual fatigue. A complete protocol is in warm-up sets in strength training.

Why “more pump” is no proof of a better rest

Short rests frequently increase the pump and the subjective difficulty of a workout.

That is real.

But a stronger burn does not automatically show you that the long-term hypertrophy stimulus was larger.

Muscle growth depends on several training factors together: sufficient mechanical loading, productive volume, proximity to failure and long-term progression.

If a very short rest means you manage considerably fewer high-quality reps in the next set, the extra pump may have been bought with a loss of performance.

Conversely, you do not have to let every trace of local fatigue disappear either. On isolation exercises in particular, a somewhat denser set structure can be entirely productive.

So the question is not:

“How maximally recovered am I?”

But:

“Am I recovered enough for the next set I have planned?”

Practical tips

Use a timer — but not as a prison

Many people estimate rest times badly.

A timer is therefore helpful, especially when you want to keep your training conditions comparable.

You could set 2 minutes as a minimum rest, for instance, and then decide:

• ready → start the set
• still badly out of breath → wait a bit longer

That gives you structure without artificial false precision.

Supersets as a time-saver

If you want to shorten a 70-minute workout, you do not necessarily have to cut the recovery of the same muscle group.

You can pair two exercises instead.

Examples:

• biceps + triceps
• bench press + rows
• lateral raises + leg curls

A 2025 meta-analysis found similar long-term strength and hypertrophy adaptations from supersets as from traditional sets, at around 37 % shorter session duration on average.

Antagonist pairings in particular can preserve rep performance well.

Match the rest to how hard the set was

An RPE value can be a practical clue.

• Heavy set near the limit → rest longer
• Moderate set with several reps in reserve → often possible to go shorter
• Isolation set → local recovery is usually the main factor

That is a heuristic, not a mathematical rule.

What about maximal strength?

For maximal strength, the case for longer rests is particularly simple:

You want to produce high forces at high technical quality.

If your next heavy set is still limited by the previous one, you are no longer training the same quality of performance.

So on heavy singles, doubles and triples, 3–5 minutes, or longer where needed, is entirely normal.

That does not mean long rests build strength themselves. They let you execute the heavy work you planned more effectively.

Rest periods in practice

The timer in hitPR starts automatically after you log a set. You can store different rests per exercise — three minutes after squats and 90 seconds after lateral raises, for instance.

The practical advantage is less “perfect science” than consistent conditions.

If you compare the same exercise across weeks, you are more likely to know whether performance really changed or whether you simply rested 45 seconds today instead of two minutes.

Conclusion

Rest periods are not a training method of their own. They are a precondition for the next set reaching the quality you planned.

For hypertrophy, the current evidence argues against permanently very short rests: more than 60 seconds comes out somewhat better on average. At the same time, there is no good reason to turn “longer is often better than very short” into the rule that “every hypertrophy set needs at least two or three minutes”.

Rest as briefly as makes sense and as long as necessary.

On heavy compounds that is often several minutes. On isolation exercises, frequently considerably less.
