Eases lower back stiffness and neck clench. Sit near the edge of the chair, feet wider than hips (knees about two feet apart). Bend forward, grasping your elbows, until the crown of your head faces the floor, and let everything hang—head, neck, shoulders, arms. Breathe in deeply; then as you exhale, feel all the tension flow from your body like a waterfall, down your spine, shoulders, neck and out through the crown of your head.
