The Rest Rule That Pumps Up Muscle Growth
It’s the type of advice that has been repeated so many times you assume it’s true: if you want to build muscle, keep your rest short. That’s how you keep the intensity up, spike your hormones, get a pump, and grow.
However, resting at least 1.5 to 2 minutes between sets seems best for building more muscle, and even longer rest if your primary goal is strength.
