I agree. If you're serious about going to the gym, the first thing you should do is get some help figuring out what to do. If this was really on a recommendation from a doctor they probably would've suggested getting a PT involved if the fatty wanted it. When my brother started going to the gym to lose weight and get fitter (he wanted to apply for the army), the first thing he did was get a PT to help him. There is no sense going to the gym with no idea what you're doing and expect to get anywhere.
