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 pectoralis major and minor are the primary muscles in the chest region. Perform bench presses and decline bench presses to develop muscle mass and strength in your pectoralis major. Focus on your pectoralis minor muscles by doing weighted chest dips. Perform three sets of 10 repetitions for each exercise to develop muscle strength and size in your chest area.
