Start with imprinted position. Legs parallel and adducted, extended on diagonal as low as imprint can be maintained, ankles plantar flexed, toes gently pointed. Arms long by sides, palms down, scapulae stabilized. Inhale and flex at hips to hinge legs toward torso, then sequentially articulate spine off mat from tailbone to upper thoracic area and reach legs overhead, parallel to mat, then exhale and reach legs to ceiling (weight remains on upper thoracic area with whole spine somewhat flexed), inhale and continue reaching toes to ceiling without putting excessive weight on cervical spine, exhale and maintain extension in hips as much as possible and sequentially articulate spine down to mat, one vertebra at a time, maintaining imprint as legs return to diagonal.
