When we are talking about Chins, are we referring to the palms facing away (reverse grip) type that I had thought. I got a little confused when some members were talking about narrow-grip (palms facing body) form used to hit biceps more...I thought these were considered pull-ups. If for example one of these forms is chosen, would the other be neglected or would you just do both? It would seem that the narrow grip pull-up would have less impact on the lats, so I wouldn't want to ditch it completely...but the workout might get too difficult if doing 2 exercises that are both very strenuous and similar, one would most likely suffer.
