Pressing a barbell overhead is one of the oldest exercises in the gym. It might well have been the first exercise invented after the first barbell was discovered. Since it is performed while standing with the bar in the hands — after the bar is cleaned from the ground to the shoulders, or taken from the rack at shoulder height — the entire body is involved in the exercise. From the floor to the hands, the job of pressing the bar overhead is shared by all the muscles in the body.
But for some bizarre reason, the press has acquired the entirely undeserved reputation as a dangerous exercise for the shoulders.
Due to a poor understanding of the mechanics of the movement, doctors and physical therapists commonly advise against performing this perfectly natural and perfectly safe exercise. The alleged problem is an injury known as “shoulder impingement,” and nothing could be further from the truth. The correctly performed press (incorrectly-performed exercises do not count) is not only perfectly safe for the shoulders — more importantly, the press is the best exercise for keeping shoulders strong and injury-free. Here’s why.
