LOVE this place. Extremely knowledgeable, accommodating and (most importantly) friendly staff. I'm a new regular-- I admit that Bikram, no matter where you go, IS on the pricey side-- but the health and sanity benefits I've experienced since starting my practice outweighs the $99/month charge.
It is a TOUGH workout. Seriously. The only goal your first class is simply to stay in the room for the full 90 minutes. It's intense-- but you will have the greatest sense of accomplishment once you are done! I've recommended this place to many of my friends, and not one of them has been disappointed.
BYT frequently advertises unlimited month-long memberships on Groupon, which I highly suggest purchasing. That's how I got started!
It's definitely NOT hoity-toity or snooty. The other yogis are super-nice, REAL people who are supportive of each other.
Also, they just had a remodel of their lobby and changing room areas. Classy, eco-friendly & beautiful!
Bottom line? If you are adventurous enough to try a legit DIFFICULT workout, Bikram Yoga Tempe is definitely the place to go.
