The Criss Cross is an alternate Jumping Jack movement. Start from standing, then hop your feet outwards. As you hop back inwards, cross your feet in front. Jump out, then right back in, crossing the other foot in front. Next, add the arm motion. With your arms at your side, swing inwards, crossing your forearms in front of your body at the same time as you cross your feet together. Pick up the pace as you are able and move continuously through this flow.
