Flex and Fit is the new gym at the Duke Energy center and I love it already!  I went for their hot yoga class this past Wednesday and it was a really good workout and fun.  The facilities are really nice too. I haven't gotten a chance to try out the air yoga hammocks, but I saw them and I can't wait to try that class.  It looks like they will also have spin classes and other workout classes and I saw free weights.  I'm really glad there is finally a quality yoga studio that offers other forms of exercise as well.  The cooking classes look like they will be really interesting as well, I will update my review once I have had a chance to try it.  The location is also really convenient and you get 2 hours of free parking which is key.  I'm really glad Charlotte is finally getting some gyms that you'd normally only find in bigger cities!
