What I know about body mechanics, I learned from my own body, running for 43 years and counting. What I said about landing over the center of gravity (a consequence of hip/torso alignment, not vice-versa) has been crucial to being able to still run 70-90 miles/week, feel better now than I did 10 years ago, and be almost as fast.
One indication that you're landing over your c.o.g. (or close to it) is that the ground impact feels lighter. Like you're patting the ground instead of pounding it, because you're not braking by overstriding. But as I say, this cannot be forced by itself. It starts in the hips,core,abs.
And you have to concentrate on it, at least I do, since decades of bad running habits never go away. Fortunately when I lapse my knees remind me to shape up.
Agreed. Younger folks get their panties all bunched up when you say land over your COG. True, nobody actually lands directly over the COG without falling, but the sensation is one of landing as close to directly over your COG as possible.
When I'm really in the zone the only tension I feel in my entire body is about an inch or so below my navel. Everything is just spinning around that point. It's like the planets spinning around the sun; the sun does not feel the planets. Yet if the sun tried spinning around any one planet there would be chaos and I dare say some planets might sustain an injury!
The difficult thing about conversation is that you can not tell somebody something they don't already know. You can try, but they will interpret what you say incorrectly as something they already know, but is different.
I think that's why the clever saying came about that says, "those who speak do not know; those who know do not speak."
