exc3 Pull-downs or pull-ups behind the head These challenging exercises work primarily the back as well as the biceps and involve pulling a bar behind the head. Behind-the-neck pull-downs use a machine that requires the exerciser to lean forward and pull a bar down behind the neck; in pull-ups you lift yourself up to a stationary bar also behind the neck.“They put an unnecessary amount of stress on the front of your shoulder, leading to potential shoulder injuries,” Butts says. Safer and equally effective alternatives include pull-ups or pull-downs in front of, not behind, the head.
