How long should you rest between sets?

For most lifters, 1–2 minutes of rest between sets is enough for muscle growth, and 2–3 minutes or more is better on heavy squats, deadlifts and presses. The real test is the next set: if you lose reps at the same effort, you did not rest long enough.

That is the short answer. The longer one is more useful, because "how long should I rest?" is really a question about something else: how many good reps you can still do.

What rest actually does

Rest does not build muscle. Hard sets do. Rest is what lets the next set be hard in the right way, with the weight and reps you planned, instead of a set you cut short because your legs or lungs gave out first.

Cut rest too short and two things happen. You lift less weight, or you get fewer reps at the same weight. Over a session, that is less total work for the muscle. Over months, less work means less progress.

That is why the research keeps pointing at the same place.

What the studies say

• Muscle growth. A 2024 meta-analysis pooled 9 studies that changed only the rest time (Singer et al., 2024). Resting more than 60 seconds gave a small advantage for growth. Beyond about 90 seconds, the analysis found no clear further gain. The authors think short rest costs growth mainly because it cuts the work you can do in the next sets.
• Strength. A systematic review of 23 studies found that you can gain strength with short rest, but trained lifters gain the most with more than 2 minutes (Grgic et al., 2018). For beginners, 60–120 seconds was enough.
• Trained lifters, head to head. In one 8-week study, trained men did the same program with either 1 or 3 minutes of rest (Schoenfeld et al., 2016). The 3-minute group gained more squat and bench press strength and more thigh muscle.

None of this says 60 seconds is useless. You still grow with short rest. You just need more sets to do the same work, which makes the session longer anyway.

Where to start

Start here and adjust with the test in the next section.

• Warm-up sets: 30–60 seconds.
• Isolation exercises (curls, lateral raises, calf raises): 60–90 seconds.
• Machines and dumbbell compound exercises: 90 seconds to 2 minutes.
• Barbell squat, deadlift, bench press, overhead press: 2–3 minutes.
• Heavy sets of 1–5 reps: 3–5 minutes.

Add time when the set was close to failure, when the reps were high on a big lower-body lift (a set of 15 squats is brutal on your breathing), or when you are older or more trained and move heavier weights.

The test: watch your next set

The table is a starting point. Your log tells you if it is right.

Say your plan is 3 sets of 8 on the bench press at 2 reps in reserve, and you rest 90 seconds:

• Set 1: 80 kg × 8, RIR 2.
• Set 2: 80 kg × 8, RIR 1. Effort went up a little. That is normal.
• Set 3: 80 kg × 5, RIR 0. You lost 3 reps and hit failure.

That third set tells you the rest was too short for this weight. Next time, rest 2–3 minutes before the bench and see if set 3 holds 7 or 8 reps.

A simple rule: if you lose more than 1–2 reps from one working set to the next at the same effort, rest longer. If every set holds its reps easily, you can try a little less.

This only works if you know how hard each set was. That is what RIR and RPE are for. "8 reps" at RIR 3 and "8 reps" at RIR 0 are not the same set.

Common mistakes

Guessing the time. Rest feels shorter than it is when you scroll your phone, and longer when you are waiting for a machine. Most people who "rest 2 minutes" rest anything from 70 seconds to 4 minutes. Time it.

Starting the clock late. Rest starts when the set ends, the moment you rack the bar. It does not start when you finish writing the set down or when you find your water bottle.

One rest time for everything. Curls and deadlifts do not need the same break. Write a rest time per exercise in your plan.

Short rest to "save time". If time is tight, cut a set of an isolation exercise, or pair two exercises that do not compete, for example a row with a lateral raise. Do not squeeze the rest on your heaviest lift.

Too much rest on warm-ups. Warm-up sets are light. 30–60 seconds is plenty. Save the long breaks for the sets that count.

How Peak Health handles rest

In Peak Health you set the rest time for each exercise when you build the routine. In the gym, the rest clock starts when you log the set, so the time is real and not a guess. If you need 15 seconds more or less, that is one tap, and the next set is ready when the time is up. See how the rest timer works.

The short version

• Rest 1–2 minutes on most exercises for muscle growth.
• Rest 2–3 minutes on heavy barbell lifts, and 3–5 minutes on very heavy sets.
• Rest 30–60 seconds on warm-ups.
• If you lose more than 1–2 reps from one set to the next at the same effort, rest longer next time.
• Time your rest from the moment the set ends.
