Head Banger pull ups are a great variation. Focusing alot on the Outside of your lats, rear deltoids, forearms, biceps, and if you keep your legs up a great exercise for the abdominals. Make sure your able to perform at least 10 perfect form chin ups before attempting these. Make sure the bar is stable before attempting this, do not suggest on a home pull up bar. If your Not Able to do as much range of motion as us, simply Do What You Can while Keeping Your Head Above the bar. Gripping pull up style will work the forearm more, chin up grip works your biceps more.
