Does short rest boost testosterone and muscle growth? We dive into the science of the acute hormonal response vs long-term muscle gains.
When you are in a calorie deficit, your recovery capacity drops. Learn why resting longer during a cut is the secret to keeping your hard-earned muscle.
The old rule says 'rest 60 seconds for size.' New science suggests that resting longer allows for more volume, more tension, and ultimately more growth.
