In high school I think I managed to do 14 or 15, but I'm not sure how many I could do now. Back then I was only able to do about 40-45 push-ups in a row at max, but now I could do several sets of 50-55 push-ups, so I might be able to get some where between 16 and 20 pull-ups. I'm a really skinny person, but really strong for my size in comparison to other people.
