Military Press

Overhead shoulder press driven by the anterior deltoid, with pectoralis major, upper trapezius and serratus anterior assisting.
Detail
The military (shoulder) press is the example exercise for the anterior deltoid (forward flexion — raise arm overhead). The anterior deltoid is primarily involved in pressing movements and is prone to an "over-used syndrome." Positioning the upper arm 45 degrees away from the torso is an important safety factor to prevent subluxation of the shoulder joint; a neutral grip is a more functional way to train this muscle. Shoulder presses (and behind-neck presses) train the anterior and medial deltoid. For overhead lifts where the spine may hyperextend (military press), a weightlifting belt serves to protect the back.
