A Well-Defined Chest Routine. 1  1. Do exercises that work the whole chest such as pushups, barbell bench presses, dumbbell bench presses, dumbbell flyes and cable flyes. Perform these exercises to trigger muscle fibers throughout your pectoral muscles and get an all-around stronger, more defined chest.
By krunoslav on May 17, 2014 Upper chest exercises. The incline dumbbell press is a great way to stimulate your upper chest muscles. Similar to the incline barbell bench press, incline dumbbell bench press allows a greater range of motion and so is of even greater value in functional terms for sports training purposes. Besides working the upper part of the chest, the secondary muscles involved are the front delts and the triceps. The only difference between this exercise and the incline barbell bench press is that in order to stabilize the dumbbells your body needs to recruit more muscle fibers to keep the weight balanced.
