Here we go...
 

Another LBG first.

I'm not going to "touch" this one.
Seriously though, the plane descriptions are helpful. I think.:doh:

Bagger

He wouldn't have to if the head remains steady and the eyes are fixed on the ball. The eyes would, as Lynn teaches, monitor any movement off the ball.

Homer does write about the four snares- bobbing being one of them.

But what Annika will explain is that while the head remains steady- the spine adjusts itself during the pivot.

AND... you would never know it until you see/understand how this study explains what the spine does in a pivot. Another notch in our development of knowing what the golf swing is all about.

Get big chested !:)

The 4 sections change. Something to do with Pitch, Yaw and Roll, if I remember one of Annikans earlier posts correctly.
The spinal column is rotating in a diagonal or oblique plane which is a combination of those great pics!.

Correction.- Axis of a diagonal or oblique plane.

My vote is for #4.

I think from down the line view many like to draw a straight line to represent the spine and its angle. And I think, no real knowledge that although that is nice and maintaining the angle from down the line seems to make sense to me, the spine is not a straight line and in order to accomodate rotation and shifting, parts must be in motion.

All time great post
 

I'd vote this into the all time greatest post on this forum! I've gotta stop laughing to catch my breath!:laughing9

I think he said if you have an apple you can cut it three ways.

Spine
 

The way I understand this is... there ideally is little, if any change in the angle of the TORSO when one is bent over the ball, and throughout the Stroke. There is no BOB or SWAY. The different parts of the SPINE(cervical, thoracic, lumbar, sacral)however, DO CHANGE during a swing.

Tiger Woods, and Adam Scott would be obvious examples of this. Their cervical and thoracic angles obviously change from their Address angles, but the overall TORSO angles are very much the same as at Address.

Lagster..Nice Post!!!

Looks like the 4 sections of the spine experiencing changes to maintain a steady pivot center is kickin arse...Wonder why?
