Answer 1

Answer: We describe the main muscle that does an action as the agonist. It is sometimes also called the “prime mover”. Many actions in the body do have one muscle that is responsible for more of the work in that action than any other muscle. For example, the agonist, or prime mover, for hip flexion would be the iliopsoas.
