Although I can understand the mechanical logic of moving the right shoulder parallel to the downswing plane (eg. elbow plane), I would imagine that one's ability to do so depends on spinal flexibility.

Here is a photo of Paula Creamer during the downswing.



She has amazing spinal flexibility and can tilt her right shoulder significantly downwards. I think that middle-aged/elderly male golfers are severely handicapped in terms of spinal/torso flexibility. Is there a suitable compensatory movement that can help them?
