Enter: Lie on your back and lift your hips, supporting your lower back with your hands. Round your back and drop your feet over your head toward the mat. The weight of your body should rest in your shoulders. Straighten legs as much as you can, continually supporting your lower back with your hands or resting them down on the floor to help balance.
Exit: Slowly roll back down to flat, supporting your spine the entire way. Try to roll one vertebra at a time.
