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.
The chest is important BUT you should only work it as much as you do the other major muscle groups. There are many different variations of the bench press that are great exercises. Dips are my personal favorite chest exercise and one that you should be doing most of the time.
