What are muscle pairs?

One muscle of the pair contracts to move the body part, the other muscle in the pair then contracts to return the body part back to the original position. Muscles that work like this are called antagonistic pairs. In an antagonistic muscle pair, as one muscle contracts, the other muscle relaxes or lengthens.
