I bought a deal-a-thons deal for Gyan Yoga. It's my first experience with hot yoga, even though I've been practicing 1-2 times/week for a few years. After my second class I was hooked! Gourav is my favourite instructor. The style of instruction might not be for everyone. Like another reviewer said, you won't get any of the fluffy hippy yoga stuff here, and I'm grateful for it! In just 3 weeks I've gone 4-5 classes per week and have definitely already noticed improved flexibility and strength.
If you're not sure, check out one of the $8 classes, you don't have anything to lose!
PS. as feed back on the other user comment, they do have a shower now if you want to change there.
