It won't be the first time I'll be working out seriously and vigorously though. A little back story: Went to college and ballooned up to about 260lbs (I'm 5'10"). I got tired of being fat so I tried eating right and started running and riding a bike a lot. (Running started at 1-2 miles, then went up to 6 miles; biking started at around 10-12mi, then 50-60 mile rides). I got down to 175lbs and was in decent shape - not much definition, I didn't have much muscle mass. I am now close to 200 again because I've been pretty dormant and haven't been very active due to being busy at work and girlfriend stuff. Well, I have decided to get back into shape and am signing up to join a gym tomorrow. It will be my first actual gym membership as the only gyms I've ever used is apt complex gyms for free. I didn't want to pay for a membership, but the group classes they offer sold me. I am really interested in the "boot camp" and "300" workout programs. That's it. Just wanted to introduce myself and see if you guys had any tips so the brolly motherfuckers won't beat my ass over some stupid shit if I do something wrong in the gym.
