Begin sitting with your legs extended in front of you. Slowly roll onto your back, raising your hips into the air. Interlace the fingers in a double fist to help draw the shoulder blades together, and extend the arms straight.
Extend your legs over your head, hips over your shoulders. It's OK if your feet don't touch, or if you have to bend your legs a bit.
Hold for five breaths and then slowly lower your hips to the floor, lowering one vertebra at a time. Hug your knees into your chest.
