Agonist muscles are the primary muscles responsible for producing movement. However, synergist muscles are helper muscles that assist the agonist in executing a particular movement. Synergists help stabilize the movement and control the direction in which the force is exerted.
Muscles can be classified into agonist (prime mover) muscles that directly produce a desired movement, antagonist muscles that oppose the action of agonist muscles, and synergist muscles that assist the agonist muscles in performing a movement. Additionally, stabilizer muscles provide support and stability to joints during movement.
The primary movement is called the Prime mover or Agonist
The two functional characteristics used to classify muscles into classes are agonist and antagonist. Agonist muscles are responsible for causing movement, while antagonist muscles work in opposition to the agonist to help control the movement.
in the arm: bicep contracts (agonist) triceps relax (antagonist) in the leg: hamstrings contract (agonist) quadriceps relaxes (antagonist) remember the agonist is the muscle "agonising" to do the work - like pulling the joint.
The agonist being the biceps brachii group. The two synergist muscles that assist the biceps brachiiare the brachialis and to a lesser extent the brachioradialis.

Agonist & AntagonistsAgonist is the muscle responsible for the primary movement ( muscle that contracts)Antagonist is the opposite muscle that must relax to allow the agonist to move a joint.
