Doing too many sets in one workout might actually stop your muscles from growing as much as they should. Instead of building more muscle, pushing your volume too high in a single session could lead to fatigue and poor form, which ultimately reduces your gains.

Doing more sets in your weight workouts might actually make you gain less muscle—each extra set could slightly reduce your muscle growth, so more isn’t always better.

If you’ve been lifting for a while, doing more workouts over time will help you build more muscle than just lifting heavier weights.

Whether you lift heavy weights for fewer reps or light weights for more reps—as long as you push until you can’t do another rep—your muscles grow about the same amount.

Higher weekly resistance training volume leads to greater muscle hypertrophy in trained individuals.

If young men lift light weights with very short breaks between sets for 8 weeks, their upper arms grow more than if they lift heavy weights with long breaks—even if they do the same total amount of lifting—because the short breaks create more muscle-burning stress that helps muscles grow bigger.
