If it were possible to have antagonistic muscle pairs in an arms contract simultaneously, the arm would be locked in position.
How do antagonistic muscle pairs work?
Tendons allow muscles to exert force on bones. They pull on our bones and related body parts to move them; this activity is referred to as muscle contraction. In "antagonistic muscle pairs," muscles function. A pair of muscles work together to move a body part, and then the other muscle in the pair works together to bring the body part back to its starting position.
Antagonizing pairs of muscles are those that function in this way. When two muscles are antagonistic, one contracts while the other relaxes or lengthens. The muscle that is lengthening or relaxing is referred to as the antagonist, while the muscle that is contracting is referred to as the agonist.
