Passive Hanging

Grip a bar with both hands and let your feet leave the floor completely, arms straight and shoulders relaxed rather than shrugged up toward your ears. This is not a pulling exercise, the goal is to let your own body weight stretch your shoulders and spine while you hang there doing as little active work as possible. Let your legs hang loose or cross your ankles, whatever keeps your body still and calm. If your grip starts to give out before your shoulders feel like they have had enough, that is fine, lower yourself down and reset rather than fighting to hang on.
