Sit on floor facing away from direction of crawling path. Place arms back to each side and bend knees so hands and feet are on floor. Raise hips off of floor.
Crawl backward through crawling path.
Standard hand position is typically pointing out to sides, however, hands can also point back as shown. Intensity is normally increased by crawling faster. Although not commonly performed, crawling up long incline surface (eg: grassy hill side) would also make exercise more challenging. Also see Crab Walk traveling forward.
