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.
Muscle activation. Push Ups and Bench Press mainly do the same thing â they target chest, front shoulders, triceps and lats in a pushing motion. However, when doing Bench Press the weight moves and the upper body is stabilised on a bench, which makes it easier to focus on your chest and push more weight. In Push Ups the body is moving instead, so the exercise involves more joint motion and importantly - more core activation for stabilisation.
