It starts supine, imprinted position. Legs adducted and parallel, extended out on diagonal as low as imprint can be maintained. Arms long by sides, palms down, scapulae stabilized. To begin inhale and hinge legs toward torso, then sequentially articulate spine through flexion off mat, one vertebra at a time, from tailbone to upper thoracic area, and reach legs overhead, parallel to mat. Then axhale reaching legs to one side, and begin to roll spine sequentially in a straight time onto mat. Continue rolling down, allowing feet to draw outline of circle. Reach legs out on diagonal once tailbone rests on mat, maintain imprint. Circle legs to opposite side and begin rolling up other side. Inhale and continue rolling spine off mat, sequentially articulating to reach upper thoracic area, with toes returning center overhead.
