I’ve got about 30 years of yoga practice with some excellent instructors both live and on-line, but this course (and the really excellent “84 Postures”) advances things to an entirely new level. Also, you can adapt it to your own body and expertise and it’ll protect you from being injured (and if you got hurt in the past you’ll probably learn why). I don’t know Simon personally–I actually found his site completely by accident–but he brings an approach that feels like “true yoga” with real concern and none of the nonsense, and it’s mixed with a genuine Western knowledge of human anatomy and physiology. Great stuff.
