Led Primary Series is a counted style of class for those familiar with the First/Primary series of Ashtanga Yoga, and is intended as a way of learning and memorizing the sequence. Each of the postures is counted in accordance with the traditional Sanskrit vinyasa for that posture. This class is appropriate for students of any level who have learned the postures with a teacher previously. For those who have learned only a part of the Primary Series, you can practice up to the pose which you have learned, and then skip forward in the video to the back-bending and finishing postures to complete your practice.
