Longer breaks between lifts = bigger muscles?
The Effect of Inter-Set Rest Intervals on Resistance Exercise-Induced Muscle Hypertrophy

Some people thought taking short breaks between weight sets would make muscles grow faster because of hormone spikes. But this review found that’s not true — longer breaks actually help more by letting you lift more total weight.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.

Longer breaks between sets during weight training allow for more total weight to be lifted, which increases the mechanical stress on muscles and may promote greater muscle growth.
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.
Whether you stick to a fixed rest time or rest as long as you feel you need to, it doesn’t seem to make a big difference for building muscle.
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 though lifting weights with short breaks makes your body release more growth hormone, that doesn’t mean you’ll grow bigger muscles over time.
