The agonist muscle is also known as the prime mover. This is the muscle that produces the desired movement of the exercise. For example, when you perform the lifting phase of a biceps curl and flex your arm, your biceps muscle is the agonist.

Example: Biceps curl the biceps is the agonist muscle causing the movement and the triceps are the antagonist muscle working in opposition to the biceps. The function of a fixator muscle is to stabilize the origin of the agonist muscle so that it can move efficiently.

Two of the most common ways to label muscles are with the terms agonist and antagonist. The agonists are the prime movers during an exercise. Antagonists do the opposite movement of the agonist. A muscle can have either label depending on the focus of the strength-training exercise.

It can also slow down the movement of the agonist muscle to prevent tearing or overuse. An example is the biceps and triceps muscle group. When you do a biceps curl (see image above), the agonist muscle is the biceps, and the antagonist muscle is the triceps.

Antagonist and agonist muscles work in pairs to accomplish a full range of movements and actions. Muscles, however, are not specifically antagonist or agonist. Depending on the movement required, a muscle can be an agonist in one motion and an antagonist during another action.

It can also slow down the movement of the agonist muscle to prevent tearing or overuse. An example is the biceps and triceps muscle group. When you do a biceps curl (see image above), the agonist muscle is the biceps, and the antagonist muscle is the triceps. Now this is where it can get tricky.

1. Agonist: The agonist in a movement is the muscle(s) that provides the major force to complete the movement. Because of this agonists are known as the ‘prime movers’. In the bicep curl which produces flexion at the elbow, the biceps muscle is the agonist, as seen in the image below.

When you bring the hand toward the shoulder, the biceps is the agonist muscle and the triceps is the antagonist muscle. In the last newsletter, we discussed the elements of alignment. I hope that you have had the opportunity to focus on your alignment both in and out of the hot room.

For every movable joint in the body, there are two opposing muscle groups: the agonist, which moves the segment of the body in one direction and the antagonist, which moves it in the opposite direction.

During elbow flexion where the bicep is the agonist, the tricep muscle is the antagonist. While the agonist contracts causing the movement to occur, the antagonist typically relaxes so as not to impede the agonist, as seen in the image above.

what i the agonist muscle do
The agonist muscle produces the desired movement of the exercise.
