Lie flat on the mat on your stomach. Squeeze your inner thighs together. Inhale and exhale normally as you pull the belly button to the spine and slowly lift the arms, chest, neck, and legs off the floor. Point the toes and extend through the legs. As you breathe, alternate arm and leg movements up and down. Count from one to 10, starting with the right arm movement. Keep your entire body rigid, moving only the arms and legs.
