I've tried a few classes on an intro deal. I find the constant yakking of the instructor really irritating. And they appear to recite a script so they are always yakking the same thing! It's not nearly so athletic as power vinyasa - you just sweat massively because the room is boiling. And the whole place smells like hot sweaty rubber yoga mats! Not to mention the dullness factor of it being exactly the same thing every time. I can't understand the popularity. Anyone else had this experience? I'm going back to my usual favourite place at the end of the week.
