Been at x-sport since like 09. $39 a month that whole time. At the time I sign up they had a 1/2 off sign up fee so I paid $75 + $39/mo, no contract. All of the larger x-sports have b-ball courts, pools, and chick classes (if ur into that).
I just saw a thing at x-sport that is buy 1 year get 1 year free. I have no idea the details but I imagine it will come out to less then the $39 I pay per month. Though since you are looking for no contract, that kind of makes it like one since you buy 2 years off the bat, so maybe not for you. You can also get a 7 day free pass to try the gym out.
The huge downside to x-sport, and I imagine this is a problem at most places, is how insanely crowded it can get at peak hours. Right after work at 5:30 is just awful to try to do a real workout on some days. Mondays are the worst, I just do whatever I can on Mondays. Weekends are good though.
