The shoulder or deltoid is made up of three muscular heads: anterior (front), medial (middle), and posterior (rear). Each head plays a different role in how the shoulder moves. The front shoulder raise mainly works the front head of the shoulder, although each head assists with the movement. As with most shoulder exercises, this one can be performed seated or standing. It can also be done one arm at a time or in alternating fashion. Here is how it's done:

Grasp any form of weighted resistance and place it on your thighs. Raise your arms out toward the front of your body until they are parallel to the floor (about shoulder height). Slowly lower your arms and repeat the exercise. You should exhale as the arms go up.
