A pull-up is an upper-body strength exercise. The pull-up
is a closed-chain movement where the body is suspended by the hands,
gripping a bar or other implement at a distance typically wider than
shoulder-width, and pulled up. As this happens, the elbows flex and the
shoulders adduct and extend to bring the elbows to the torso.
