The nice thing about the Cross Crawl? You don't actually have to be on the ground to do it. While it's a crawling motion, this move is done while you're standing up--and it can be done anywhere.
In this video, health and fitness expert, Cynthia Sass, RD, shows you how to do the cross crawl: First, stand with your back straight and your arms raised to the ceiling. Then bring your right elbow down and your left knee up to meet it. Alternate sides for two minutes, going as fast as you can.
