The pectoralis major of the chest, more specifically the sternal head, is the prime mover of the pushup. This muscle originates at the sternum and inserts at the humerus, or arm bone. The other muscle of the pectoralis major, which is the clavicular head, is involved, although to a lesser degree, during the movement.
What joints are used in a push up?

What is the antagonist muscle in a push up?
For a pushup, the antagonist muscles are your back muscles (their “pull” motion is the opposite of your chest muscles’ “push”); your biceps (they oppose the motion of your triceps); and your rear deltoids, or the back-facing fibers of your shoulder muscles, which oppose the motion of the anterior deltoids
What is the stabilizer muscle in a push up?
During the push-up exercise, the short head of the biceps brachii muscle acts as a dynamic stabilizer. This means the muscle activates at both ends—the elbow and the shoulder—to help stabilize the joints.
Do stabilizer muscles grow?
They help coordinate and stabilize the movement, and they work to restrict the movement of the joints involved in the exercise so that the joints don’t get injured. When a muscle acts as a stabilizer, it contracts, however, it doesn’t significantly lengthen or shorten as the primary movers do
What’s the agonist and antagonist in a push-up?
Specifically, the short head assists the pectorals and anterior deltoids to horizontally straighten your shoulders. Therefore, the biceps short head can be referred to as an agonist during the pushup, while the biceps long can be called an antagonist.
Is a push up flexion or extension?
Essentially, a single pushup involves the movement of the arm through a variety of anatomical positions. At the end of the pushup, though, when your arms are straight out and your body is held away from the floor, your shoulder will be in a flexion position; shoulder extension is not involved.
What is the concentric phase of a push up?
For the press up, the concentric (up) phase occurs when you push yourself up off the floor. Depending on how you position your hands, either flexion or horizontal flexion occurs at the shoulder.
