HOW: While placing both hands up against the wall for support, begin by sagging your hips to arch the back. Then push back into a child's pose against the wall, the goal is to stretch the back into a rounding position. Repeat this movement back and forth with control.
FEEL: When you drop your hips you will feel the abs and the low back stretching into the arched position. When you bring your body down towards the floor you will feel the low back muscles being stretched.
