But one thing I would disagree with is that "blending" is learned mostly or entirely in the dynamic type of training. Can't blending of structures and the forces they produce be done very thoroughly in static? That's what I use static training for.
In my opinion, blending can't be learned in a static fashion, at least not the kind of blending I'm talking about. You can learn the movements, and technical details of the blend, but the blend itself requires motion. Static is just that, void of motion.
Without this motion you can't learn the natural timing of the event, and how to move your body inside of that timing. This is what I call (and I believe my teachers were calling) "Aiki"; although there is much Aikiweb discussion of this.
