I know what you are thinking looking at my photo - dude, you're fat. You can't do yoga. Not only that but I am as flexible as a board. Nevertheless, I took advantage of the Groupon recently that provided one month unlimited yoga and a 60 minute Swedish massage for $50 - so I am definitely going to get as much as I can from the place.
One thing I really like is that it is conveniently located next to the light rail. The Osborne stop is right there in front of the studio. My first visit I thought it was difficult to find - the studio is on the side of the Lexington One building, but I couldn't see that from the street. There is a parking garage next to the studio which makes parking convenient if you drive.
The studio is very clean and peaceful. I like the boutique, although they do not have many fat boy clothes. The locker rooms are very nice and clean. I love the sinks. A locker is available to store your items while in class. The rooms where the classes are held are nice and spacious. I started with the Slow Flow class and have also went to the Zen class. Both instructors were excellent and even though I looked like Kung-Fu Panda, I didn't feel uncomfortable. It was interesting to see that the students were all ages, both men and women. A very good mix and all have been friendly. The staff is friendly and helpful. If you do not have a yoga mat, you can rent one for $2.
If you live in Central Phoenix, this would be an ideal location. The problem for me is that I live way out in Queen Creek, so I doubt I go on the weekends, but it isn't too bad coming from work. Definitely give this place a try if you live in town. Don't worry if you have never tried yoga - I have found the staff and instructors very helpful in working with newbies.
