The Tiger crawl is one on the fundamental warm-up movements we perform at CATS.  This movement is a combination between a Spiderman stretch and a Bear crawl. The objective is to stay low and try not to extend your arms, kinda like staying in the half push-up position as you move forward.  The gliding disc's you see here are used to help slide along the track and keep a fluid motion while not having to lift up your arms.

The hip should drop down and touch the turf or floor as you shift from side to side.  This a challenging movement and recruits pretty much all the muscles of the body and provides an excellent dynamic warm-up.
