What is the role of a synergist in movement?

Explanation:
Muscle synergy involves muscles that accompany the main mover to produce a smooth, coordinated action. A synergist helps the primary mover by contributing additional force and guiding the movement, and they can help stabilize the joint to prevent unwanted motion so the prime mover can work more efficiently. In other words, the role is to assist the prime mover rather than initiating the action on their own. For example, during a biceps curl, muscles like the brachialis and brachioradialis assist the biceps in flexing the elbow, providing extra support and stability to the movement.
