The typical person's COG lies just in front of the second sacral segment when they are walking, which puts it dead center in the Kwa. I don't think this location changes much when doing Wing Chun, unlike when doing styles that drop down into low stances. The Kwa can be used to express power in Wing Chun techniques as long as the pelvis is not rolled forward and "locked in", which effectively keeps the Kwa from moving on its own. If the Kwa is allowed to "float", then it can amplify a wave-like motion that is initiated with the legs. The power produced is like snapping a whip. Picture the legs as the handle of the whip, the Kwa as the junction between the handle and the body of the whip, the spine and arms as the body of the whip, and the hands as the tip of the whip. This can certainly be trained! But its better seen and felt than explained in words.
Chiro Keith!
I found that fascinating about S2 being where a moving person's COG is. Thanks for sharing. This, again, backs up why L5-S1/S1-S2 joints are always the chief complaint for back pain. In my world, the Kidney energy governs the lower back, so I generally just treat Urinary Bladder 23 (Back Transporting Point of Kidney) @ L2.
Back on topic, while the WC forms train wonderfully where to put your COG (SNT=Sitting, CK=Shifting/Moving, BJ=Bending), I personally think that by trying to hit a heavy bag, structure and COG is rocked and is then made to adjust. This, plus trying to hit a moving target (missing) messes with that COG.
So, for me, forms, heavy bag hitting, and missing all fix and stress the COG.
I hope to meet you one day, Keith. I think we'd have a lot to gab about!
Best,
Kenton
