Why is it considered contraindicated to perform overhead presses behind the neck?

Performing overhead presses behind the neck is considered contraindicated primarily because it increases the risk of injury to the rotator cuff. This position can lead to abnormal shoulder mechanics and excessive strain on the shoulder joints and surrounding tissues. When the arms are elevated behind the head, the shoulder is placed in a more vulnerable position, which can compromise the stability of the rotator cuff muscles and tendons. This is especially problematic if the individual lacks sufficient shoulder mobility or strength, leading to potential impingement and other injuries.

The mechanics of this movement can lead to an uneven distribution of forces throughout the shoulder complex, further exacerbating this risk. Therefore, it's crucial for individuals to prioritize safer overhead pressing techniques that keep the arms within a more natural range of motion in front of the body, thereby reducing the likelihood of injury and promoting better joint health.
