When I am not in school, I use the country club that's in our neighborhood. It's a pretty new place and the workout facilities are incredible, not to mention that the dining area across the walk-way is also great to pick something up on your way out of the gym.
www.cityclubatriverranch.com It's quiet and there are always personal trainers around if you need their assistance. It's nice b/c I can go lift weights without having a buddy to come and spot me...they do it for me.
When I'm at school, I just use the rec. center on campus. Actually, I take that back...I hardly go. The weight room is entirely too intimidating to go and lift weights in. I mean, if you're not benching 350 lbs you might as well leave. So, due to my extreme embarassment of my size, I tend to run the lakes around campus and ride 3 to 4 horses a day for my cardio and then I mess with the dumbbells that I have in my condo. Hey-you gotta do what you gotta do to keep in shape!
