Begin on hands and knees. Check to ensure that your hands are directly under your shoulders and your knees are directly under your hips. Inhale as you look up and release your belly toward the floor. Exhale as you move through neutral spine to arch your back up and look at your bellybutton. Once again, inhale as you look up. Exhale as you look down. Continue the movement of the pose with the breath for a few moments.
If your shoulders are tight, try to focus your arched spine more into the shoulder blades. By separating the shoulder blades the tension in the shoulders will begin to release.
Follow this pose with either cobra and/or child's pose.
