Arnold used single-joint movements to complement overhead presses and isolate each delt head individually. Here, too, he sought subtle differences that would, over time, build better overall size. For example, the cable lateral raise in front of the body has a slightly different feel than when the cable runs behind you. Knowing how to do a given movement pattern on different pieces of equipment is, according to Arnold, essential for a bodybuilder to take his physique to the next level.
