Deltoids

The Deltoid Muscle has an Anterior Head (front side), a Middle Head and a Posterior Head (back side).  The shoulder joint is a ball and socket which gives it an incredible range of motion.  At the same time, this causes it to be more vulnerable to injury and dislocation compared to other joints.  For this reason it is important to properly exercise each part of the Deltoid Muscle and strengthen all of the smaller muscles of the Rotator Cuff (such as the Supra- and Infraspinatous, and the Teres Minor).  These muscles are also strengthened though upper back exercises.
