I haven’t written much yet about adding push hands to my movement practice, mainly because I don’t feel competent to describe it well.
Push hands is a taiji training technique—a way to learn how to accept and redirect force. I view it as falling roughly at the midpoint between taiji as moving meditation and taiji as a martial art.
My taiji teacher wasn’t really interested in push hands, I think because he wasn’t really interested in the martial aspects of taiji. He did give us the barest exposure to pushing, so I wasn’t a complete novice, but nearly so.
I am interested in the martial aspects of taiji, so I was delighted last year when I met a couple of people who were interested in pushing. We got together several times last fall, then let our training fall by the wayside over the winter, but started meeting again once the weather turned nice in late spring.
One of the friends I push with describes push hands as a test or diagnostic for your form practice: If your form practice is sound, you will be good at push hands.
Already my push hands practice is informing my form practice, as I learn to shift my weight to move, but simply to turn my waist to accept and redirect energy. I’m trying to learn to keep my shoulders down (a work in progress), and I’m trying to learn to keep my arms and shoulders connected to my core (same, but with less progress).
