The Physics Of Push Hands

Here's a nice example of some push-hands techniques that I think transfer well into self defense application. This instructor appears to be able to develop some real throwing power. It appears effortless not because of power, but his keen sense of the physics involved. You can call it Yin-Yang action, or push-pull, but his best tosses involve letting one side go, or yield, go yin while the other side goes yang and pushes or shoves out. Sometimes it looks like he is holding the steering wheel of a large truck and making a sharp turn. Of course, he convienently has his leg posted as a fulcrum to rotate his opponent around.
The other thing I see is that one way he captures the opponents center is by locking a limb (arm) straight and connecting right to the center-- the other is to collapse the arm, fold it up to provide the links of a chain that can be wound into a chin-na joint lock. I'd love to train with this guy. His website is www.wudanginternal.com
