Taking longer breaks between sets of weightlifting doesn't hurt your muscle growth—you might even grow more muscle with longer breaks than with very short ones.

Even if you rest only 20 seconds between sets instead of 2 minutes, as long as you do the same total number of reps and weight, your muscles still grow and get just as strong.

If you're someone who lifts weights regularly, taking longer breaks between sets might help you gain a bit more muscle than shorter breaks—especially if we're using precise tools to measure those gains.

Inter-set rest intervals exceeding 60 seconds promote greater skeletal muscle hypertrophy compared to rest intervals of 60 seconds or less, when training volume and intensity are matched.

We don't have enough solid proof yet to say if taking short or long rest breaks between sets at the gym makes a real difference in muscle growth.

Resting more than a minute and a half between sets doesn’t seem to help you build more muscle than resting for about a minute — it’s not worth the extra time.
