The stinky factor: don't wear any chemicals,including deodorant to class so you can sweat - its not stinky unless it hits clothes I think...but be clean as ya can..we have a floor that is antimicrobial and doesn't stink up like carpet can..I agree that "the series" can get tedious, so I mix it up..and we added a class called""hot vinyasa"" - which is yoga in heat and I use what I learned from Doug Swenson (the yoga teachers' yoga teacher!)...some folks like the same old routine every class - I like variation....so come to see me in Williamsburg!!! And don't be intimidated, if you can do Cathe, you can do hot yoga!
