This contraction works the rectus abdominis. A muscle that can move the joint opposite to the movement produced by the agonist. This is not intuitive, and many adults who do exercise on a regular basis often do it improperly, excessively favoring a specific muscle group during their workout in order to acquire a desirable body feature.
