This is essential for maximizing strength, as greater velocity on the bar throughout the movement preferentially stimulates muscle growth of the more powerful fast-twitch muscle fibers. It also induces post-activation potentiation and increases neuromuscular efficiency, which collectively drives remarkable strength gains. CHAIN-LOADS POTENTIATE MUSCULAR STRENGTH Post-activation potentiation (PAP) is the increase in muscular force production that occurs as a result of maximal activation of the muscle from a previous lift.
