Antagonist and agonist muscles often occur in pairs, called antagonistic pairs. As one muscle contracts, the other relaxes. An example of an antagonisic pair is the biceps and triceps; to contract-the triceps relaxes while the biceps contracts to lift the arm.ntagonist and agonist muscles often occur in pairs, called antagonistic pairs.

A antagonist muscle is the muscle that opposes the agonist. So using the same example, during a biceps curl, the triceps is the antagonist muscle. This muscle relaxes as the biceps contracts. A synergist muscle is one that stabilizes a joint around which movement is occurring and helps to create movement. So again with the curl example, the brachialis and brachioradialis are the synergists muscles. They assist the biceps muscle and stabilize the elbow. When dropping the weight back down during a biceps curl exercise, the triceps becomes the agonist muscle and the biceps becomes the antagonist.
