During the concentric phase of a reverse fly exercise, the shoulder joint primarily goes through horizontal abduction as the arms move outward away from the body. The scapulothoracic joint also engages to stabilize the shoulder blades and maintain proper alignment. This coordinated action involves the posterior deltoid and other muscles of the upper back to perform the movement efficiently and effectively.
The muscle of the pectoralis is antagonist to the latissimus dorsi during the shoulder adduction. The anterior fibers are involved in shoulder abduction when the shoulder is externally rotated.
The antagonist muscle group for a pull up is the pectoralis major, which is primarily responsible for shoulder adduction and internal rotation. In addition, the biceps brachii serves as a synergist muscle during the movement.
The antagonist in shoulder extension is the shoulder flexors, which are the muscles responsible for flexing or bending the shoulder joint. They work in opposition to the shoulder extensors, which are the primary movers in shoulder extension.
Reverse dumbbell flys, also known as posterior deltoid raises, develop several key muscles areas. They strengthen the posterior aspect of the shoulder muscles called the deltoid. They work the supraspinatus, infraspinatus and the teres minor, which are the posterior muscles of the rotator cuff. Reverse dumbbell flys also target the upper back muscles which pull the shoulder blades toward each other.
