Start in a tabletop position with your hands underneath your shoulders and your knees underneath your hips.
Inhale as you lift your head and tailbone, belly melting toward the floor, as shown. This is cow pose.
Exhale as you round your back and draw your abs in toward your spine, tucking your chin to your chest to find a stretch between your shoulders. This is cat pose.
Alternate between cat and cow for three rounds of each pose, one breath per movement.
