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.

When you lift light weights until you can't go on or until you slow down, your muscles swell and your blood gets more acidic in the same way — meaning your body reacts similarly to both methods.
