2-H "On Plane" Right Shoulder Motion is possible only by tilting
its axis, the spine.

This led me to think that the upper spine, near the right shoulder
had to tilt back to accomodate the right shoulder to get the
shoulder on plane. The hip turn and shoulder turn makes the
axis tilt look like it is leaned back to accomodiate the right
shoulder on plane. The set up axis tilt also seemed to confirm
the same thing.

Then Yoda dropped a boom shell when he said that the bottom of
the spine moves slightly away from the target with the weight
shift (a Hip Motion). Later Lynn said "In contrast, some instructors --
perhaps even most -- teach that the top of the spine tilts away
from the Target in the Backstroke. They lable the move as an
"athletic" Pivot. I lable it a Sway".

What a great post. It cleared up so much. I certainly hope that
the forum picked up on it. The post brings up a whole new world
for current thinking. I hit 2000 balls working on the correct concept.
I feel much more leverage and a since that the right elbow is going
through impact with a lot later release and a complete hip turn
to a complete the finish.

Bucket, you had a post "Who ain't got no Axis tilt? I ain't got no
Axis tilt". Did you ever get it worked out?

Still working on it . .. David Orr has a fantastic video on what the spine does at his site. Really really good.

Anyhow . . . Axis Tilt or the amount of tilt . . . when it tilts . . . is HUGE. First of all the top of the axis is basically the center of the shoulder turn which the left shoulder is attached to which controls low point. So you certainly want to pivot in a way that has the center of the shoulder turn . . .well . . . Centered. But then it becomes how much you slide your hips and turn your hips and where they go . . . of course the left shoulder basically locates low point and the right shoulder is part of the power package. So the shoulder turn being centered is huge for solid contact reasons . . . curvature reasons . . . angle of attack reasons . .. hand path reasons . . . plane shift reasons. . .

The axis of the spinning shoulders is big big part of the machine producing precision alignments.
