To recap, as we flex (or curl) our arm, the bicep functions as the agonist muscle during its contraction, whereas the tricep is the antagonist muscle, as it relaxes. Synergist: Adductor Magnus.

Its an absolutely crucial component of any kind of action, and works alongside the antagonist muscle to create contractions and extensions. muscle).

When squatting, quadriceps and gluteus musles are going to be the agonists. This occurs from a standing position when a person elevates their knee toward their abdomen (femoral-on-pelvic hip rotation) or when bending forward from the trunk, as if touching their toes (pelvic-on-femoral rotation). This means less pressure is placed on the agonist muscle, which here is the bicep, and theres therefore more pressure on the antagonist muscle (in this case, the tricep). While from a biomechanical perspective this variation enables the lifter to complete the exercise with higher loads because range of motion is reduced, it may not be the safest variation on articulating joint surfaces for beginning exercisers who have no desire for improving their 1RM. > Stand up straight until hips and legs are fully extended.

A more concrete example of this would be the two muscles we find in our upper arms, which we used in our previous agonist muscle example - the biceps and triceps.
