I'm a 17-year-old guy, 5'8, and weigh about 125lbs. I'm a vegetarian, which keeps me even thinner than usual, on top of my high metabolism. I've really never worked out, to be honest. I walk to school, and seem to be in surprisingly decent shape, all things considered.
However, I've got pretty much nothing as far as the upper body goes, so I'm looking forward to the pull-ups and push-ups. I've got a movie night with friends at 7:00, so I'm going to change into some better clothes and get to work in a few minutes to squeeze it in beforehand. I don't have a pull-up bar yet, or anything I could really use as one, so I'm not sure what to do in place of those. Any suggestions?
Anyway, I'm really hoping this helps!
