    muscles usually work in pairs or groups e.g the biceps flexes the elbow and the triceps extends it. this is called antagonistic muscle action. the working muscle is called the prime mover or agonist.(its in agony!) the relaxing muscle is the antagonist.the other main pair of muscles that work together are the quadriceps and hamstrings.the prime mover is helped by other muscles called synergists. these contract the at the same time as the prime mover.they hold the body in position so that the prime mover can work smoothly.

    Agonists and antagonists:- How muscles work in pairs? Muscles work in pairs. The AGONIST is the working muscle; for example, the muscle contracting (biceps muscle). The ANTAGONIST is the relaxing muscle. Here, the bicep is the agonist (or prime mover) and the tricep is the antagonist. This process of one muscle relaxing and one contracting is called reciprocal inhibition.
