Have another hold a finger BARELY above the base of the 'neck bone.'
Make a backstroke.
What happens?
The 'neck bone' moves WAY forward.
What is that, reverse swaying?
I don't know what it is exactly, but it is NOT rotation about a fixed point...
'cause the point is MOVING.
Guess I don't know where the neck bone is, cause yes I can feel the outside move, but it is rotating around. At issue is where is the center point and does it move. Is it the 'thoracic spine rotation center'? Now I did your test sitting down, I was attempting to minimize any movement other than the shoulders, don't know if that will make a difference.
The more I read what you write, I guess I am of the opinion that you don't subscribe to 1-L-1/2 cause you keep introducing movements and seem to be supporting your position that even the base of the neck movement is not only permitted but desired.
Oh yeah...
...also notice I cleaned up your work , (much clearer...lol)
Hmmmmm No.....
Your yellow line goes right through Sam's Shoulder Blade...lol
Now, I knew there would be no picture with lines on it that would prove/convince you to you what im about to show you - so I took extreme measures ....lol
Now I don't believe you can argue with this line right ?....
Ok, lets look at the backstroke...
Notice how at address the spine is tilted towards the target and how the spine leans away from the target....
Now look at the photo of snead again beside me....
Is this supposed to be cleaning up my work, or you just not doing your homework ?
