For those who have never done ashtanga yoga or have only done Jeff's series of three beginner ashtanga yoga videos, this class is very challenging. It moves at a quick pace, flows through many advanced yoga poses and is meant for students who have previously practiced the half or full ashtanga yoga primary series. For those who have, this class, skillfully lead by Jeff Lichty, will help you move through the sequence without needing to remember what comes next.
