I thought I might join in, did my initial test, and decided that no, I will not join in. I did plenty...I don't need to do 100 in a row. FWIW, push ups (many different kinds) have been a big part of my PT routine, so I will keep doing them.

But if anyone is serious about the pull up challenge, I'd be up for that. My pull up-ing has seriously lagged since surgery (since I turned 40 my goal is to do the number of pull ups that I am old on each birthday--with rest, obviously--and if I want to be able to do that next birthday, I need to get back into the routine).
