A pull-up is a variety of upper-body compound pulling motions for the purpose of exercise. The most popular current meaning refers to a closed-chain bodyweight movement where the body is suspended by the arms, gripping something, and pulled up with muscular effort. As this happens, the wrists remain in neutral (straight, neither flexed or extended) position, the elbows flex and the shoulder adducts and/or extends to bring the elbows to or sometimes behind the torso. © 1985 Didier Ruef
