I can do about 4 good pull-ups where I go all the way back down before the next one. I used to not be able to do any though. I heard that it's really hard for girls to do them, so I feel pretty good about it. When I couldn't do any, I built up my strength on the lat pull down machine, but instead of pulling the bar down behind my back, I imitated the motion of a pull up by pulling the bar down to my chest. I started out at 60lbs and I have slowly progressed up to 100 lbs. I weigh 117, so I can do a few real pull ups. I think it's pretty effective. That way I could do the whole motion, just with less weight.
