I enjoy this version of power yoga. I like the pacing of it. It is not much about the philosophy, and to me, that's ok; I'm there for a workout.
I think the temperature of the room is pleasantly hot. It's not unbearable, and they do turn on the fan when it starts to get too hot. The fact though that there are no showers and no real locker room is why I bumped my review down to 4 stars. The facilities in general are lacking (only 1 bathroom too, and 3 changing rooms).
The class moves quickly if you take the "all levels" option. There is very little instruction on how to do the poses, but even my husband, a true beginner, kept up OK (he looked at me with some concern in his eyes only once or twice).
I wish there was a location closer to the 'burbs. It's tough getting to and parking in Shadyside, but luckily there are free 2-hour spots if you can find them.
