Re: The Leather Man
In may respects, the fascia argument is besides the point. There are concrete training methods out there that produce replicatible results. You don't need to know the bio-mechanics to perform the exercises. You just have to concentrate on the feelings that these techniques produce. I certainly don't think, "and now I engage the fascia," when I practice.
But at some point, though, students are going to start asking, "why am I feeling these sensations?" The fascia argument is just (in my opinion) the most plausible theory.
And I will say, the theory makes more sense once you start experiencing things. For example, you feel various sensations "under the skin". What's "under the skin"? The fascia.
