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 fix is easy-- stretch the chest muscles (doorway stretches for example) nd strengthen the weak mid back muscles with exercises that pinch the shoulder blades together. Most importantly, you must correct the slouched, hunched over round back posture that got you this way. For this, see a website by Jolie Bookspan. You must do the exercises and stretches OFEN- 2-3 times per day for 45 minutes each time-- stretch the chest whenever you see a doorway, and have good posture ALL THE TIME.
