Found a Groupon for this place and went to their River North location in Chicago so I figured I'd try it out. I went to the AIR Foundation class on Monday with Alicia and loved it!! The staff there is incredibly helpful and energetic. They will help you find the correct length silk for you and if you get there a little before class, they can help teach you some poses. The class is taught similar to a barre class so it is more strength training than it is truly yoga. The instructor offers variations for every single exercise. So if you don't feel ready to hang upside down on your silk, you don't have to! I can't wait to go back!
