This scares me a little - this lovely picture here - because she's flaring her nostrils a. bit. too. much. I wonder if that's a necessary position for the nose in this video. Or maybe when you exercise as much as she does, your nostrils just stay in that flared, slightly freaked out position. Who knows.
On second thought... maybe it's not about the abs, maybe it's about distracting everyone away from your "problem areas"... this just might work. Flare away nostrils, flare away!
