Horizontal adduction is most common during which type of movement?

Horizontal adduction is a movement that occurs when the arms move towards the midline of the body, typically in a horizontal plane. This type of action is most prominent during pushing movements, such as a bench press or push-up, where the arms extend out and then return towards the center of the body as the exercise is performed.

During pushing exercises, the chest and shoulder muscles are engaged, and they contract to bring the arms inward — a classic example of horizontal adduction. The emphasis on this movement pattern is evident as the upper body is actively involved in pushing against resistance.

While pulling movements also involve arm action, they are characterized more by extension and retraction rather than the adduction motion that occurs during pushing. Squatting primarily involves lower body muscles and does not typically engage horizontal adduction, and rotating movements involve a different range of motion, focusing on twisting rather than adducting the arms. Therefore, pushing movements facilitate horizontal adduction most effectively, making it the correct choice.
