As a three or so times a week yoga practitioner for about the last three or so years, I now have an even greater appreciation of challenges of strength, balance, and coordination demonstrated in these videos. We see it in gymnasts and acrobats as well as yogis. This Youtube video, like those of Damian Walters (2009) and (2010), makes me green with envy. I feel like I ought to get down and give 10 every time I see something like this. Amazing stuff.
