Not really sure why all the bad reviews. This location is pretty huge compared to some of the other ones and it's very new. It's a bit of a ways out there, but location is irrelevant since everyone lives in different areas. But it's close to the 215 and easy to get to.
We come here primarily for Scott's yoga classes on Thurs nights since we have a closer location if we wanted to just work out. This location has a dedicated yoga room. Which means many times after class, if you want to stay and talk with the instructor, or stick around and play around for a few more minutes you can. There isn't another class waiting to come in. Well that is my experience at least from the times we go.
I've also found the instructors to mostly be very good, and several of the teachers teach at other locations as well as other yoga studios around town (which is a great deal to get some of these teachers if you are familiar with yoga studio monthly fees). Go to a few classes, find your favorite teacher and stalk, er, I mean follow them to their other classes.
The only thing that kind of bugs me is that you can hear the music from the pool or other parts of the gym, and sometimes you really need that peace and quiet.
Edit: When it rains, here are plenty of leaks from the roof. The worst is on the second floor. Watch your step!
