My arms are alright and I'm a bit of a health freak so it's not my diet, but I'd like to tone up at bit. I think sit ups are going to be the best thing for me. Can anyone recommend something to keep my feet down? I've tried putting them under my chest of draws and it f*cking kills my feet. I'd also like to do some pull ups. Anything anyone can recommend for a bar for that? I don't really want one that goes in the door way otherwise I'll probably end up like one of those people in youtube with a broken nose.
