UP IN ARMS: PHASE 2

An arm-centric routine that works other muscles along the way, ultimately making you bigger and stronger everywhere. In this three-week phase, the arm exercises will put your body at different angles -- leaning forward, lying back -- which will produce two interesting effects: First, because of the angles, you'll find it hard to move the weights using any muscles other than those in your arms. In other words, you can't cheat. Second, you'll put your muscles under a new type of stress, which in turn will provoke a new muscle-building reaction from your body. Another new technique is trisets, which are supersets with three exercises performed consecutively without rest in between, instead of two. You'll also do more abs exercises and more, faster intervals. Six days a week, ongoing.
