Set up with both feet on a wall, pushing through the balls of your feet. Inhale, then exhale as you lift your chest up. Inhale again as you draw a knee off the wall toward your chest and rotate your sternum toward that knee. Exhale and rotate to center; press that foot into the wall, ensuring solid contact through the ball of the foot before switching to the other side. Try to keep your pelvis stable throughout and use your core to stay lifted and rotate.
