They need to put a real sign up, but I guess I'm just glad that there was a sign because I would not have found it. All I was told was to look for the Whole Foods. I came here because I knew someone who teaches classes here. I just met her a couple of days before through a mutual friend and was looking for something to do in the morning, and thought it would be great to workout. Boy, did I ever workout! I have been to hot yoga classes at the Crunch Fitness Centers in Chicago, and this was just as awesome. Guys, if you literally want to see girls sweat - this is the place. Every single person in here was drenched in sweat. I mean it was slick and shining on everyone's bare arms and face. We did almost every yoga pose I knew or could think of, and a little ab workout is added at the end. The studio itself isn't large so that you get the attention and benefit of a private class. The instructor is helpful with the poses, and she enunciates really well. I suppose if you have taught English before you should. I can't expect anything less from a Chicago transplant! Go see Jenny! They have first timer specials and offers. They do sell limited amounts of yoga items. They may hae a few extra mats if you forget yours, but I'd recommend getting your own if you decide you want to continue on doing more than one class.
