Last summer I could only do maybe 5-6 chin ups (underhand) and even less after I rested. For the past two months ive been doing Christopher's modified version of Bill Star's routine and now 13-14 chin ups on the first set. Same with overhand pull ups. But, when pull ups, my hands are only shoulder width or a little bit wider than that and I go up until my neck is higher than my hands. Is that the right way to do it? Havent tried wide grip yet but Ill probably only be able to do a few.
