The muscle that performs the same movement as the prime mover is known as a synergist. Synergists assist the prime mover in executing a specific movement, stabilizing the joint, or reducing any unwanted motion. By working together, the prime mover and synergists ensure more efficient and coordinated movement. An example is the biceps brachii acting as a synergist to the brachialis during elbow flexion.

The prime mover is a conceptual term from Aristotle's philosophy to describe an unmoved mover that initiates all motion in the universe. Therefore, nothing performs the same movement as the prime mover since it is considered the ultimate cause of all motion.
A synergist muscle helps a prime mover muscle in creating a specific movement. It assists the prime mover by reducing unnecessary movements and helping stabilize the joint. Synergist muscles work together to produce coordinated movement.
An antagonist muscle reverses the action of a prime mover. When the prime mover contracts to produce a movement, the antagonist muscle relaxes to allow that movement to occur in the opposite direction. This coordination between prime movers and antagonists is essential for controlled and coordinated movement.
An agonist (prime mover)
The muscle that is primarily responsible for bringing about a particular movement is called the prime mover or agonist muscle. It is the main muscle that contracts to create the desired movement at a joint. Antagonist muscles work in opposition to the prime mover to control the movement and prevent injury.
Prime mover is the bicep and the antagonist is the tricep.
The muscle that is responsible for most of a movement is called a prime mover. It may also be called an agonist.
the prime mover is the muscle responsible for most of the movement in a group of muscles; called the chief muscle.
a prime mover is the main muscle that causes movement. In the case of the hip flexion, the prime mover would be the rectus femoris or the ilopsoas
