Sit in a chair that has a firm, tall back that comes up to just below your shoulder blades. Grasp the sides of the chair, lengthen your torso, and while remaining seated, lean back over the top of the chair, lifting your sternum toward the ceiling and broadening your chest. Breathe normally, keeping your inhalations and exhalations smooth and even. Stay in the pose for 4 to 6 breath cycles. Repeat one more time, if desired. Exhale as you come out of the pose.
