A lot of universities keep their free stuffs open to alumni. Maybe you could see if that's the case for yours as well?
As for me, I have wonderful metabolism, much like Chobi. I'm on my feet for ten hours a day, and at least three days a week, I exercise. Nothing majorly exciting -- pushups, situps, jogging every now and again. Every Tuesday, I play kickball with some coworkers.
My diet, however, is quite appauling. I eat way too much junk and rarely any vegetables. I'm trying to work on it though. I'll occasionally eat an apple or a plum... but that doesn't happen too often. Oh well...
