The first workout starts with a modified tri-set for the chest, designed to pump your pecs and stretch the connective tissue that surrounds them, thereby allowing more room under your skin for the muscles to grow. The second chest blast is done by pairing pushups with very heavy sets of dumbbell bench presses.
Breathing in, lift the barbell from the rack and lower it to your chest. Breathing out, press the weight up until your arms are straight. Repeat as many times as your exercise program dictates. Flat bench presses focus on most of the pectoralis major muscles of the chest.
