2nd class. I was weak to comment after the first class. I'm not sure why there are negative reviews. This place is clean. Very clean for what is going on. Instructors know their stuff. If you feel dizzy you simply stop & compose yourself. I'm a raw rookie. Trust me this isn't easy but I feel incredible after the class the next day....lol .... I got a 10 day groupon and its $$$ well spent. I will say this.... Park close to the door on your first few classes. Its a long walk to the car afterwards when your legs wobble.
