excerpt:
These last few agonizing reps are especially potent, because the closer to muscular failure and the greater the fatigue, the greater the number of motor units (and muscle fibers) called into action(28-31). In other words, the intensification tactics ensure loading across a maximal number of motor units and thus muscle fibers. That’s one reason why John calls these “the difference makers.”
