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.

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.

The common advice to rest only 30–90 seconds between sets to build muscle might need updating — longer breaks (over a minute) seem to help a little, but not enough to be sure it’s worth changing your routine.

Taking a bit more than a minute between sets when lifting weights might help your arms and legs grow slightly more muscle, but the difference is so small it might not matter much in real life.

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.

Whether you take short or long breaks between sets at the gym, both can help you build muscle — as long as you train at least twice a week for a month or more.
