Just because short rests make you feel more tired and your muscles burn more during one workout doesn’t mean they’ll make your muscles bigger over time—you’d need to study people for months to know that.

Inter-set rest configuration effect on acute physiological and performance-related responses to a resistance training session in terrestrial vs simulated hypoxia

Randomized Controlled Trial

The study only looked at short-term effects like heart rate and tiredness during one workout, not whether muscles get bigger over weeks or months, so it can't tell us if this training style builds muscle long-term.

Similar Assertions

You can build muscle just fine whether you rest for 30 seconds or 4 minutes between sets — the exact rest time isn’t a make-or-break factor.

80%

Whether you push your muscles to complete exhaustion or stop a few reps short doesn’t change how much rest time between sets affects muscle growth.

76%

We don’t know if resting longer between sets helps people who already lift weights, older adults, or muscles in the chest and back — there just isn’t enough research yet.

75%

Resting for 1 to 3 minutes between sets doesn’t seem to build more muscle than resting for 1 to 1.5 minutes — the difference is too small to matter in practice.

74%

You don’t need to take shorter breaks to build muscle than you do to get stronger—both can be done with the same rest times if you lift the same amount of weight and do the same number of reps.
