So, Life Time Fitness... what more could you want in a fitness center?
The facilities are all top-notch and well maintained/clean. They have plenty of lanes for swimming (over 10 if memory serves me correctly), the rock wall is cool, the exercise and weight lifting equipment are great, and there's tennis if you're into that. For the membership fee, you do get a lot for your money.
If you're looking for a fitness center that has nearly everything, this is your place. Very happy!
