Lie on the floor on your right. Press actively through your right heel, flex the ankle, and use the outside of the foot to stabilize the position (if you still feel unstable, brace your soles against the wall.)
Bend your right elbow and support your head in your palm. Bend and draw the knee toward your side. Take hold of the left big toe with your index and middle fingers. If you’re not able to comfortably hold the toe, use a strap On an inhale, extend the leg up toward the ceiling.
The raised leg will likely angle slightly forward, while the top buttock will drop back. Firm the sacrum against the pelvis; this creates a kind of fulcrum that will help you move the leg slightly back toward a perpendicular position.
