Shoulder retraction vs scapular retraction

I think I may have been confusing just pulling my shoulder back in its socket(movement 1) with true scapular retraction (movement 2). One feels like a country and the other like a continent. Does the first motion have any place in the STS model, or is it just part of the second, larger move?

TIA,

Shoulder mechanics are a little tricky. It's easy to define the movements, but then in practice the movements are often blurred together. I'd say both versions you demonstrate are scapular retraction. One has more depression and the other might even have a slight amount of elevation. The first move is more what the lead shoulder would likely do, the second is better for the trail shoulder.

Happy Golfing,
