Single Push Hands is the introduction to two person work in Tai Chi. It teaches and trains in four concepts fundamental to the practice of Tai Chi as a martial art. These are Leading (an attack into a non-threatening place), Adhering/Sticking (as an opponent attempts to find freedom to mount an attack), Following (when an opponent retreats), and Attacking (when you sense there is a vulnerability where you can take advantage).
