More like 2.5 stars.
This place is kind of a clusterfuck. The evening classes are always PACKED, so you have to go early to sign up outside which is more difficult and confusing than it should be.
Most of the classes are taught by the owner - and I don't think she is a very good yoga instructor. She is more of an aerobics/fitness instructor - she wants you to feel the burn, push yourself to your limits and plays loud pop music during class. The instructor who does the Tuesday/Thursday evening classes is much better and yoga-ish, its more relaxing while still getting in a good sweaty session. I always feel so good when it is over!
Something about this place that really skeeves me out: Towards the end of class, before relaxation, the instructor (and 2 volunteers) come around and give EVERY person a little back and foot massage. That would feel nice if this were a normal yoga class, but considering how much everyone is sweating, its kinda gross. I don't know if that is normal for hot yoga classes, but its unsanitary...
Sometimes the owner locks her dog up inside her car while she is in class, which I think is mean. I hope she doesn't do that in the summer time.
