Video-explanation of "Sun Salutation"

I like this clear explanation of this exercise. This is not my preferite training,but I like it too and do sometimes but I had never find a video so good as this.



Sun Salutation you can find in many sites.Here for example, in this page, you find the same sequence but in photos, and it says about:

"Often considered the core of hatha yoga practice" and precise that "are practiced in a row of 2-6 times and traditionally practiced at sun rise".
