Major Muscles and Actions Involved
In the 45-Degree Triceps Extension the triceps brachii muscle is involved in elbow joint extension. In this action the forearm moves away from the upper arm, which is held stable, to a fairly straight, upright, arm position. In addition, full extension of the arms makes execution of some sports skills even more effective.
