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.
Chest, Shoulders and Arms. The chest, shoulders and arms are a group of muscles that specific kettlebell exercises engage together. Most kettlebell arm exercises are specific to both the triceps and biceps, but some exercises engage the whole upper body. The kettlebell swing is an excellent example for upper-body strengthening. Stand with your feet shoulder-width apart and hold one kettlebell with both hands. Keep your hips bent back and swing the bell back between your legs. Pause for a count of one second, then swing the bell upward toward eye level.
