The Left Wrist is Clubface Control (1-L)

[EdZ]

The Machine has only one function--to execute the program.

Clubface Motion is Rotational Wrist Motion and forearm motion.

…..

Keep in mind that the right forearm and elbow are the 'guide' in terms of any 'rotational' motion.

That is to say, swivel (startup and finish swivel) are not the same as hinge action.

Depending on the components used, hinge action may 'feel' like one smooth, constant swivel/rotation - but ALWAYS with the straightening right arm (with a bent right wrist) being the 'gatekeeper' for your Rhythm and rate of clubface closing.

Drill taking the club back to about hip high, flying wedges in place, and slowly straighten the right arm towards your impact fix hand location. You'll see that if the right forearm, the angle of approach, is correct, that the rate of clubface closing isn't a constant swivel action, even if it feels that way in some procedures (a true 'swing' with its throw out).
