As I’m sure you know, many a yogi (I’ve seen it!) does not look like a rail or a think beauty, even after practicing 10 years and teaching. I’ve seen some beautiful, curvy women who have mastered their practice. My comment from the Twitter yesterday still stands: I thought you looked great in your yoga pictures, and when I saw you in-person. And I’m not being flattering; I’m being honest.
That doesn’t solve your question, though. So, my answer is: If you’re unhappy with it, kick your gut’s ass—evict it! xo
