Dr Mann
Do you think this a valid biomechanical way to set the lead wrist and trail wrist early in the backswing?
Giles Gill suggests using different biomechanical actions depending upon whether the golfer is left or right side dominant.
When he described the left side dominant biomechanical action, the 'kinetics' aspect seems to be different to 'extensor action' (see other you-tube video below) which uses PP1 via the trail hand?
Giles Gill is suggesting using a downwards motion of the lead shoulder to transmit a pressure force via his lead hand pointing towards his trail foot in the takeaway that starts setting a flat lead wrist relatively early in the backswing, which he claims also tends to keep the lead arm straight. This pressure force seems to be applied in a similar position as PP1 but via the lead hand not the trail hand.
GG claims that this subtle method promotes many other favourable biomechanical actions in the golf swing.
GG does seem to contradict himself from 1:52 because he says if we see a player with a flatter to flexed lead wrist, that it's going to promote a square to slightly closed clubface. But then he shows how forward lean at impact will open the clubface relative to the ball-target line.

But then he shows how forward lean at impact will open the clubface relative to the ball-target line. DG I think that GG's opinions are nonsensical!!! First of all, there is no such thing as being left-or-right hand dominant in a TGM swinging action type of full golf swing action. All golfers who play from the right-side are presumably right hand dominant, but when performing a full golf swing action using the TGM swinging technique it is fundamentally a pivot-induced lead arm swinging technique. He wrongheadedly claims that the lead wrist will only manifest an increased degree of cupping when the lead wrist upcocks (= moves towards increased radial deviation) when the lead arm is lifted away and not when the golfer is pushing downwards with the lead shoulder during the lead wrist upcocking phenomenon. That's not true! He wrongheadedly claims that extending the trail wrist during the takeaway closes the clubface. That's not true! The clubface will appear closed between P1 => P2 using a trail arm-only swing action if the right forearm is kept more pronated. However, if the golfer moves the trail forearm towards supination (= lesser degree of pronation) when performing the takeaway between P1 => P2 then the clubface will not face groundwards even if the degree of trail wrist extension is the same in degree. It is an optional choice whether a pro golfer wants to use an early lead wrist set (like Danny Willet) or a late lead wrist set (like Greg Norman who uses the one-piece takeaway). GG wrongheadedly states that bowing the lead wrist invariably closes the clubface. That depends on whether the lead wrist is radially or ulnarly deviated. We know that bowing the lead wrist when the lead wrist is radially-deviated to a marked degree causes little angled motion of the clubshaft and a lot of clubshaft twisting about its longitudinal axis while the opposite phenomenon happens if the lead wrist is ulnar-deviated to a marked degree.
