Linear coaches very rarely say anything about the hips because it all is about the hands so usually a linear coach will say that the 'hands lead the hips'. The hip rotation is leading the shoulder rotation in the best swings so that it makes it easier for the shoulders to rotate.

Smaller muslces of the shoulder and upper body must slow down in order to help 'pull' the hips and larger muscles of the trunk and legs along in the rotation.

You state, "The hip rotation is leading the shoulder rotation in the best swings so that it makes it easier for the shoulders to rotate." -- I would not only agree but also add that a powerful hip rotation aids in generating a more powerful shoulder rotation. So on that point we seem to agree.

Hi Jack

Hope you feel better. If you read the sentence before the statement you need clarification for it says 'Without hip rotation the shoulders have resistance to rotate because they are also trying to turn the hips.' So the statement you want clarification is referring to this meaning that the 'Smaller muslces of the shoulder and upper body must slow down in order to help 'pull' the hips and larger muscles of the trunk and legs along in the rotation.' because the hips are not going first.


So to clarify the two questions

At what time in the swing do the hands seperate away from shoulder rotation?


What is the relationship of batspeed to shoulder rotation and/or hip rotation?

I am adding a third question

If the hips are required to help rotate the shoulders and the shoulders setup more effiecent use of THT and BHT (hopefully you can clarify if this is not the case) then which movement is the most important part of the swing to maximize bathead speed?
