Tai-chi Push Hands

Are there any other people practicing push hands in this forum? This is a two person exercise that teaches you to use fluidity and flexibility in the martial arts rather than tension. It provides strategies for living your everyday life more powerfully and being unaffected by stressful situations.

Push hands is the heart of Tai-chi training and develops the consciousness of the body, so that each joint and muscle can function accurately. That state allows the body to heal itself and avoid deterioration with age.

I would like to start a discussion about your experiences with push hands.
Tai chi Push Hands

I found a interesting DVD that teaches Wudang tai chi. I am going to use it. Does anyone have more information on what it means to do Wudang tai chi or has anyone done it before?
