Look at this series of capture images of Tiger Woods swing.



Do you agree that horizontal hinging occurs in images 1,2, 3 and that followthrough is complete in image 3? Do you agree that the finish swivel is occurring in images 4 and 5?

Now, what interests me is that Tiger Woods degree of right wrist bend in image 3 is less in image 3 than image 1. Why? I suspect that it is due to pronation of the right hand and supination of the left hand, which is occurring during the horizontal hinging action phase of the golf swing. The question is whether I am accurate in my visual assessment of Tiger Woods swing, and whether this rotation of the left/right hands is part-and-parcel of the horizontal hinging action.

There is no true rotation of the Left Wrist during the Horizontal Hinge Action. Though it appears to Roll, it is merely maintaining its 'vertical to the ground' alignment.

There is a true rotation -- supination -- of the Left Wrist into Impact (Release Swivel) and out of the Follow-Through (Finish Swivel). But . . .

This is Swivel Action, not Hinge Action.
