You probably read this far because you thought that I was going to give you a miraculous exercise to increase your bust, right? Unfortunately there isn't one, since breast tissue is just fat. But you can get that fat to look a little perkier by training the muscle underneath it, the pectoral muscle. The pec is a huge muscle with fibers that run from the top of the arm to the bottom of the sternum. The connection with the arm is important, because at that spot the pec comes into contact with the anterior deltoid. These two muscles work together to flex the arm.
