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.
Static Exercise (meaning it does not use motion or movement), also known as Isometric Exercise, exerts muscles through contractions at high intensities (tensing) without movement of the joints. Pushing your hands together in front of your chest, where each side is resisting the effort of the other; or if you push against a wall without changing the angle of the elbows, are just two examples.
