Which exercise corresponds to the action of the infraspinatus?

The action of the infraspinatus primarily involves external rotation of the shoulder joint. This muscle is one of the rotator cuff muscles and plays a crucial role in stabilizing the shoulder and allowing for smooth movement during arm positioning.

External band rotation specifically targets the infraspinatus by requiring the arm to rotate outward against resistance, which effectively engages this muscle. This exercise helps to strengthen the external rotators of the shoulder, which can improve shoulder stability and function, especially in activities involving overhead and rotational movements.

In contrast, the other exercises mentioned do not specifically emphasize the action of external rotation. The high row and seated row primarily engage muscles involved in shoulder retraction and pulling movements, while the bench press focuses on pressing motions that primarily involve the chest, shoulders, and triceps rather than the external rotators of the shoulder. Thus, external band rotation is the most appropriate exercise corresponding to the action of the infraspinatus.
