Really this is the main reason I do hot/heated yoga. I love yoga, I love really getting into it and getting my brain calmed down. But it really attracts the fats. I've really noticed though that if they even show up to a hot or heated class they 1) can't keep up a little bit and 2) don't come back again. So over the course of the last month I've noticed a grand total of maybe 10 'smallfats' at my studio, one of which is an "instructor" and who only teaches yin class (aka the easiest class). It's awesome and one of the reasons I decided to keep going there.
