Your breasts are composed of two major muscles - Pectoralis Major and Pectoralis Minor as well as many smaller muscles. These muscles are found under the breast tissue and on the sternum, and connect to the humerus . Your chest plays a major role in helping to carry your arms on your body and shoulders forward. These exercises target your upper, middle or lower chest muscles and therefore result in a firmer bust.

Rehash the greatest number of times as you can.
