Start on all fours on a yoga mat. Ensure that your knees are directly below your hips and your hands are directly below your shoulders. Set your spine in a neutral position, and draw your shoulder blades down and back. This is your starting position.
On an inhale, lift your chin and allow your stomach to sink toward the floor. Create space between your shoulders and ears by drawing your shoulder blades down and back. This is called Cow.
On an exhale, press your hands and knees into the mat, draw your chin to your chest, and draw your stomach in to curl your spine. This is called Cat.
