Note: instead of two blocks, you can use two thick books. This is the first in a series of classes on the essential elements of headstand pose (sirsasana). In this class, Crista helps you with the strength and flexibility in the shoulders that you need to move into and out of this challenging pose, and hold it without putting too much pressure on the head and neck. You won't be doing headstand just yet, so don't be afraid! The next class in this series is Headstand Pose: Leg Strength and Flexibility.
