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.
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.
