Hmm...The only thing I can really think of to say is that I apply stance to the entire body, not as a "ski-centric" thing. Because a foot/ski is lifted doesn't mean other components of stance need to change remarkably. I suppose we are using the term stance differently, you and I, so this is, in essence, an apples & oranges thing, which is fine by me.
As far as the "maintaining stance" idea. It is a different way of looking at balancing, and I suppose it could, if presented the"right" person in the "right" way result in someone stopping movement and trying to be statue-like. Like everything the use & presentation is relative to who, what & where. Which in this case was in relation to Gr8trn aking this:
|how do we walk the line of maintaining balance through maintaining the line of action from the COM through the BOS with too much tension in the body vs. not enough tension in the body? This "functional" tension bit. How do you know what is functional?
I offered the idea up as specific "how to" experiment with discovering tension as functional and learning how much to use, since I don't think it would be really possible to explain such a thing. I believe it has to be experienced.
For years I primarily thought in the the "never stop" moving/stop movement paradigm, (which I still do, but with a more developed understanding of what that means to me). Now I can see that the exercise of maintaining stance can be what creates purposeful movements. With changing forces etc, one cannot (and shouldn't)maintain the exact same "looking" stance in all situations; but there are critical components of stance that can and should remain constant even though the body goes through a series of movements to deal with whatever it has to deal with.
Beginning and ending movements with a good stance = good balance. Since the effort in between is about keeping the body parts organized well the in between part is usually good too.
To try to be simpler,
Using muscular effort to keep a good stance results in good balancing movements.
Hey! there is snow in the mtns around here! And lots of it!
