Have any of you ladies tried this? I have two friends that LOVE this so it has made me more curious about taking a class or two. I've been warned that the first time can be a little overwhelming (and you have to get used to the smell of everyone around you sweating so much?) but my friends think I will be okay since I routinely work out 3x a week. I mainly want to try it because it's supposed to be such a great stress reliever. Please share your stories! TIA : )
