Lie on a mat or a padded surface. Cross your ankles and hug a 36-inch roller by squeezing your heels toward your hips. (Hold the roller behind your ankles, not behind your knees.) Place your hands behind your head. Inhale.
On an exhale, contract your abdominals and, without dropping the roller, raise your tailbone and hips slightly off the floor. Simultaneously roll your head, shoulders and upper back off the floor, moving your body into a tight ball. Pause at the peak of the contraction, then slowly release down to the starting position. Repeat 12 to 16 times. Rest, change the cross of your legs and repeat for another set.
