These are the hardest freakin' yoga workouts I've ever done. They are long, too, 90 minutes of insanity. They start out mildly enough with some nice, flowing vinyasanas, but then he busts out the crazy standing poses, headstands, handstands, and all kinds of insanity. It really inspires me to get better at yoga, but they also kind of intimidate me. His wife is also in the videos, and you just know they're one of those annoying couples.
