Re: A simple mechanical model of body use.
Thank you for posting the video.
I wonder. . .
After taking the time to make the video and think/feel through the process, do you have anything different to add?
Have you made any new distinctions between "activate," "raise," and "use" as they relate to the shoulder, or even about what exactly someone may mean when they say "shoulder"?
If this is not "internal," how does it fit into "internal training"?
