I used to do this kind of yoga weekly when I lived in Flagstaff, and the best part was at the end of the 90 minute, 110 degree class is you got to go outside in the cool air afterward. Not in Phoenix, no sir, you get done with the class and go outside where it's nice and hot and then get in your even hotter car. Damn.
But this is just me complaining about the unbearable heat, again. The class was awesome. The instructor was friendly and thorough and pretty much remembered everyones names.
Be sure if you go to bring a yoga mat, 2 towels, one small one to wipe the dripping sweat off your brow and one to set over your mat so you don't slip on your sweaty mat. Water, it's hot in there. I recommend putting ice in your water too, a little treat.
They also had an August first-timer special for a two week unlimited pass it's $25, which is great. I got sick for a week, so only went to two classes. Sucks because after these two weeks, I don't think I'll be able to afford to go anymore, we'll see. It's like $375 for a three month pass and $16 to drop-in, a little pricey for me. That must not be the case for everyone else though, the classes I went to were pretty crowded.
