I have to wonder, is the value in the fascia idea that there is another way to move that we haven't considered before and that maybe, just maybe there is another system in the body that maybe responsible for this and that this idea in itself opens our mind to new possibilities?
Perhaps that's the primary value. In a society where various aspects and ideas of ki are culturally instituted, maybe that's the system.
A lot of this internal discussion reminds me of arm wrestling matches when I was young and learned that I could 'resist' by relaxing, extending, and grounding out into the table my opponents force instead of pushing back.
I didn't think about ki or fascia or internal anything when doing that, just that it was interesting and that I could resist (and sometimes even overcome) a much stronger person that way for much longer.
