Synergists help steady movements and fixators help stablize the prime movers origin.

The primary movement is called the Prime mover or Agonist
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.
A muscle that assists the primary mover or Agonist
Rectus abdominis is the prime agonist and the superior and inferior oblique muscles are synergists. Erector spinae is an antagonist including a number of other muscles of the back.

Agonist is a classification used to describe a muscle which causes specific movement or several movements through the process of contraction. This is a term for skeletal muscles, usually. Agonists are also sometimes called "prime movers" since they are the muscles being considered that are primarily responsible for generating a specific movement.
One is the agonist and the other is called the antagonist. Agonist: muscle which is the main mover, it contracts and shortens Antagonist: muscle that lengthens and controls e.g. flexion at the elbow: the biceps are the agonist and the triceps are the antagonist.
