Lag and the flat left wrist.

[Yoda]

I'm having a hard time focusing on the flat left wrist at impact (need to invest in an impact bag, going to order a tac tic first though). I've been focusing more on lag recently. Would it be true to say if you maintain your lag through impact you'll be keeping the left wrist flat?

Revert,

First of all, please order the Impact Bag first. You can do so much more with it than with the Tic-Tac.

Regarding your question, generally it is true that the Flat Left Wrist is a visual clue that you have maintained Clubhead Lag Pressure. However, it is quite possible to have lost the Lag -- the stress in the shaft -- without having Bent the Left Wrist.

In fact, this technique can be delberately employed to produce a 'soft Impact' around the Greens by causing Impact to occur during the Full Extension of the Left Arm and Club (2-P). The unstressed Clubshaft then cushions the collision of Clubface and Ball instead of resisting it as would a stressed Shaft (6-C-2-C).

In such instances, Acceleration has ceased prior to Impact because the Hands have reached their maximum speed (RPM per 6-P-0 and 6-C-2-D). Thus, the Clubhead speed (also RPM) matches the speed of the Thrust (the Hands' Pressure Point Pressure) that produced it (6-F-1). When that happens, the Sweetspot 'catches up' and the Clubhead Lag evaporates.

To understand this phenomenon, visualize yourself in a car accelerating very quickly to, say, 100 MPH. The initial acceleration thrusts you back in your seat as your body strives to remain 'at rest'. However, your body has little choice but to go along with the car: It is being involuntarily thrust forward by an accelerating force. The faster the car goes, the faster you go, but because you are 'catching up', you cannot go quite as fast as the car. You are 'lagging' just a shade behind.

As the car continues to accelerate, you continue to accelerate, but again, you can't quite catch up to the car. However, once the car hits its target speed of 100 MPH and levels off at that speed, you almost immediately reach the same speed. You have finally 'caught up'. At which point, you feel no acceleration pressures whatsoever because -- surprise! -- you are no longer accelerating. You are simply motoring along with the car at high speed. In other words:

You have 'lost the lag'.
