Dear Tigersimmo,
That's definitely clearer. I will work on that and see what I think.
My immediate impression is that you are using the top-of-the-back muscles to pull the scapulae (shoulder blades) towards each other in a taut configuration. I don't think I can accomplish this postural configuration without some tightness creeping into my upper arms, especially the back of the upper arms, and some tightness across the front chest's pectoral muscles.
My second main impression is this does not appear to alter the linearity of the two shoulder sockets, being in a line parallel to the putt line in a square setup. The shoulders are just as parallel in a line when drooping as they are when the back is flattened out as you describe.
Tightness in general is a defensive posturing, as in readying the body to receive a blow or to repel an assault. In putting, tightness usually functions to block out some undesireable motion. To the extent a relaxed-body movement allows or permits or encourages unwanted motion in the putting stroke, this tightness can serve a purpose. My effort is to find keys to permitting a relaxed-body stroke that does not encourage unwanted motions.
So let's keep at it -- we seem to be onto something, focusing on a problem from different directions.
Cheers!
