Some things move and somethings get moved, understanding what this term means can make effective even dynamic movement really easy
We cannot move bones, it is not how our body works, muscles move bones, however it is an easy interface, a decent frame of reference but we should recognise it as nothing more than a useable form of shorthand.
Moving the Hips, moving the Spine, moving the Centre or similar terms are shorthand, not actual, in all instances when we move we advance our kinetic chain and as such each link so to speak only affects the link that is next in the chain, our feet move our legs, our legs move our pelvis, because our centre is located somewhere inside our pelvis the expression “move the centre” appears to make sense.
But it is false.
Some things move and somethings get moved, understanding what this term means can make effective even dynamic movement really easy, when students struggle to move correctly using either the Chum Kiu or Biu Gee methodologies it is usually a recruitment of moving parts issue and nothing to do with the Forms at all.
A good “non Wing Chun “ place to begin understanding the Chum Kiu method is by observing what is happening when you push a shopping trolley around the supermarket, with the Biu Gee method a good “non Wing Chun” way is to observe what goes on as you reach behind yourself and down to pick up the T.V. remote that you knock off the arm of your chair.
We must be sure to not confuse moving with changing location. The fact that my Elbow moves from point “A” to point “B” while performing Bong Sau does not mean that I am in reality moving my Elbow.
Movement as a power producer is always and only about momentum not relocation, revisiting the “conservation of momentum theory” can clear things up in a couple of minutes.
As I mention at the end of the video, the usual resistance training that we do in Wing Chun approaches situations in reverse, this is not a problem if we understand this, but taking our training at face value can create very real problems.
I reintroduced sparring about a month ago and it now constitutes most of our training time, sparring is not fighting, but it is a great deal closer than Chi Sau or 4 corners drills, the compression of time and space brought on by an advancing sparring partner really shines a light on the problems caused by not understanding that we train in reverse.
It is easily fixed, but until it is fixed it really messes people up.
