This is the ashtanga yoga full primary series in its traditional form, taught and counted by Jeff Lichty. If you have never seen or done the full primary series, you may want to watch this video in its entirety first. This is an advanced class that pushes even the advanced yoga student. It moves quickly and demands great strength, flexibility, focus and a knowledge of the sanskrit names. It would also help to do this class in full with someone in person before following this video.
