The overhead press (abbreviated OHP), also referred to as a shoulder press, military press, or simply the press, is a weight training exercise with many variations. It is typically performed while either standing or sitting sometimes also when squatting, in which a weight is pressed straight upwards from racking position until the arms are locked out overhead, while the legs, lower back and abs maintain balance. The exercise helps build muscular shoulders with bigger arms, and is one of the most difficult compound upper-body exercises. The world record overhead press was performed by Owhe Bruno in Russia in 1997.
