www.golfresearch.com created computer image of the golf swing.
Not sure what a previous commenter is talking about. Actually this is, to my eye anyway, a perfect representation (as is the companion vid).
One thing that really stands out is just how much the shoulders do NOT dominate the downswing — how the arms are swinging down from the inside as the shoulders retain a relatively closed position (while the lower body is opening up). At the last moment when a player can possibly be conscious of what is going on in the downswing before impact — which is about when the hands are hip-high or just getting in front of the trailing thigh — the shoulders are still staying at least slightly closed instead of "driving" anything or forcing rotation power that breaks down the swinging motion.
It is worth noting that these models are incorrect….especially regarding Hogan's hip movement.
Any way you can repost this with the image rotated 90 degrees left?
I'm curious where you found this model? Is there more information on it anywhere?
