The muscles that work to support the prime mover are commonly referred to as synergistic muscles or secondary muscles.
The muscles that work to support the prime mover are called synergist muscles. Synergist muscles assist the prime mover in executing a specific movement. They often stabilize joints and help control the movement of the prime mover. Synergist muscles can be further classified into two types: agonist synergists and antagonist synergists. Agonist synergists work together with the prime mover to achieve the desired movement, while antagonist synergists counteract the actions of the prime mover to allow for precise control of the movement.
