Ok, I always thought I was pretty good at pull-ups. I mean, I can do 15 in a row and most people can't even do 1. Well, my opinion of my pull-up strength changed when I found T-Nation. In the ABBH program (doing it right now), it calls for 5 sets of 10 pull-ups. There's no possible way I can do that. So, I've been replacing them with Lat-Pulldowns.
However, I would much rather do pull-ups, and I don't think doing Lat-Pulldowns is really going to help my pull-up strength as much as I'd like. My question is, is it OK to train pull-up strength on my off days by actually doing pull-ups? If so, how would I go about this? Should I not go to failure? Not do it after a back day? Thanks for your help!
