Daryl,
The hips and shoulders turn perpendicular to the spine.
Tilting or dropping the right shoulders has no impact at all on creating ground forces.
Another myth is creating tilting of hips and shoulders. The reason they tilt is they are reacting to the spine, Tilting is a reaction to how the spine is moving.
In golf there is slight right lateral bending of the spine. This allows to be able to drive the right arm into impact. Slight right lateral bending stabilizes at impact and extension of the upper body occurs at impact.

If you pay close attention you will notice from the beginning of hogans downswing to impact his left knee maintains the same flexion. Hogan stabilized his lower body at impact and his hps decelerate. This allowed his upper body to close.
At impact notice Hogan sternum and belt buckle are in line this indicates. his shoulders and hip are square. His hips and shoulders are perpendicular to his spine.

This was Hogans secret he knew how to create ground forces and knew how to stabilize his lower body at impact.

It's not about how big of a hip rotation you have, It's about how fast your can create speed before your lower body stabilizes at impact. Small rotation with fast acceleration is the key.
Which can reach peak speed fastest a huge hip rotation or a small hip rotation.

One other myth is trying to thrust your hips or turn them yourself. This is called superficial speed. When people try this they lack ground forces and can't create stabilization or deceleration of the hips at impact. The upper body can't catch up.Mechanics terms creates the over the top move. Everything spins out left.

Good post . . .Interesting stuff here . . . we are now back on track hopefully from all the COM COAM mess . . . this is the meat of it. . . . This is how people improve not that other crap about whether CF is there or not.

So let's have some further discussion on what you've posted above. I think this is VERY important stuff.

Really like the part about Hogan's knee action . . . Interesting that what he prescribed doing wasn't what he actually ended up doing.





To your point about Hogan's left knee maintaining its flexion . . . . you can see this very cleary in comparison of the two sequences. Also the left knee maintaining it flexion obviously has implications to the other components. Particularly the slant of the hips, spine, and shoulders . . . as you know the club responds accordingly (altering plane angle, angle of approach & attack etc.) . . . so the pivot has HUGE geometry implications. With regards to when and how certain segments get in line.

So you have mention sheer forces (sp?) force across the ground and vertical . . . Is this the left knee piece you mentioned?

Another question . . . could you expand a bit on the lateral bending of the spine vs. the hips going forward. Would the hips moving forward not also creat tilt in the spine?
