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.
Flip the position around and do incline push ups, with your hands on the bench and your feet on the ground to target the lower chest muscles. Push ups build strength and muscle in the entire torso, boosting metabolism as an extra bonus. Foot and hand variations provide an additional challenge.
