1. Agonist: The agonist in a movement is the muscle(s) that provides the major force to complete the movement. Because of this agonists are known as the âprime moversâ. In the bicep curl which produces flexion at the elbow, the biceps muscle is the agonist, as seen in the image below.
The leg curl primarily works the hamstring muscles. The three hamstring muscles are located on the back of the thigh. Two are on the inner, or medial thigh, and one is on the outer, or lateral thigh. The two medial hamstrings are the semitendinosus and the semimembranosus.
