APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -The agonist muscle groups during bench press actions are the pectoralis major, triceps brachii34 and anterior deltoid. The antagonist muscles were, therefore, considered as the posterior deltoid, supraspinatus, infraspinatus, teres major and minor.

Detailed explanation-2: -The prime movers in a bench press are the pectoralis major, pectoralis minor, and anterior deltoid, whereas the triceps and serratus anterior work to stabilize the movement. The antagonist muscles are the latissimus dorsi, posterior deltoids, and biceps.

Detailed explanation-3: -During the upward phase of the press up, the triceps contract and become the agonist, whilst the biceps relax and become the antagonist. This results in extension occurring at the hinge joint.

Detailed explanation-4: -The agonists in an exercise are those muscles directly involved in moving the weight. For the bench press, there are three main agonist muscles: the pectoralis major, the anterior deltoid and the triceps brachii.
