Push hands is really an application of Tai Chi form practice. Usually, a student is not taught push hands until the student has practiced tai chi form for a while and has a feel about the form movements, in particular: a. The sitting back movement appears very frequently in the tai chi form and is not easy to master. It is the defensive position in the push hands. b. The forward movement when you move your body weight to the front foot, such as in the walking forward brush knee is the offensive position in the push hand. c. Turn of the upper body with pelvis essentially not moving as shown in the section of Internal Discipline in the Tai Chi Overview is the ward off move in the defensive position and push off move in the offensive position. d. There are several other more subtle moves. All these moves you will learn in the form practice. What is unique about the push hands is that it provides the opportunity for extended contact time with your opponent, so-called stick to your opponent, when you can learn how to control your emotions, your body, and how to detect your opponent's intention and respond accordingly. Other kinds of sparring exercises all have such short contact time with the opponent. There is no time to learn such subtle aspects about yourself and your opponent in sparring as opposed to push hands.
