Because muscles only pull, they cannot push, they work in pairs. These pairs are called antagonistic pairs. As one muscle contracts (shortens), the other relaxes (lengthens). The muscle which is contracting is called the agonist, or prime mover. The relaxing muscle is called the antagonist.There is a thrid muscle type within this model, called a synergist.ecause muscles only pull, they cannot push, they work in pairs.
