Longer breaks between lifts make arms bigger
The Effect of Resistive Exercise Rest Interval on Hormonal Response, Strength, and Hypertrophy With Training

Two groups lifted weights with different rest times. One group rested 1 minute, the other 2.5 minutes. At first, the short-rest group had more stress hormones, but that faded. After 10 weeks, the long-rest group’s arms grew more, but both groups got equally strong.
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.
When you lift weights and rest only 1 minute between sets, your body releases more stress and sex hormones right after the workout — but only at the very start; after a few weeks, this effect goes away.
If you rest longer between weightlifting sets (2.5 minutes instead of 1 minute), your arms grow bigger over 10 weeks — even if your strength doesn’t change.
Whether you rest 1 minute or 2.5 minutes between sets, your strength gains in squat and bench press end up being about the same after 10 weeks of training.
Even if your hormones spike a lot right after your first few workouts, that doesn’t mean you’ll grow more muscle or get stronger later on.
