Shoulder adductors. Abduction means moving away from the median plane of the body and adduction means moving towards the median plane of the body.

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.
When using the reverse fly machine, the proper form involves sitting with a straight back, gripping the handles with a slight bend in the elbows, and smoothly pulling the handles out to the sides while squeezing the shoulder blades together. It's important to control the movement and avoid using momentum to prevent injury.
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 adductor longus is a prime adductor and medial rotator of the femur. It is also an assistant mover for flexion at the hip. Therefore the antagonist muscles are the abductors (apposing adduction), the lateral rotators (apposing medial rotation) and the extensors (apposing flexion). Primary Abductors: Gluteus Medius and Gluteus Minimus Assistant Abductors: Tensor Fasciae Latter, Sartorius Primary Lateral Rotators: Glutteus Maximus, Deep Later Rotator group Assistant Lateral Rotators: Sartorius, Iliopsoas Primary Extensors: Hamstrings, Gluteus Maximus Assistant Extensors: Adductor Magnus (upper fibres)
