Even for a Swinger, the L arm is inert? Why? What is TGM's rationale for this?

Re L elbow turn, why do you not recommend that? The way I see it now, it is the same as turning the L wrist, just with more consistency. And, it is sorta like just an insurance that the L forearm will behave properly at Impact and FollowThru---L elbow bending but not retracting backwards laterally to the side and remaining in front of the torso (not chicken winging), with the L forearm/wrist still being able to turn to the fullest/efficiently and L forearm going upwards. So input power is being transferred efficiently to the L wrist and to the clubhead.

And, for a Swinger who is using #4 anyway, why would turning the L elbow make the L arm exert (not inert)? The way I see it now, the L arm being Exert (sorry, easier to type...lol) will only be unwanted IF the Swinger slows down or doesn't use #4 and then rely on Exerting his L arm to Swing the club. But this is not what I'm saying. I'm saying its #4 that is the MAIN pulling power, with #3 just being made sure to perform to transfer that power to the clubhead. The L elbow turn is just for that---Transfer of Power. That's why #3 it is called Transfer Power, correct? The L elbow turn ENSURES that...no? So why not help that Transferring of Power?

SWINGER OR HITTER the left arm is INERT meaning it is simply a length to be maintained, it is the same as if you replaced your left arm with a rope, IT HAS NO MUSCULAR CONTRIBUTION, it's only contribution is it's maintained natural length to provide structure and radius to the swing. the left elbow should not bend until the FINISH not the follow through, the right arm should never be straight until the end of the FOLLOW THROUGH. the arm movement you're describing sounds as if you are not clearing the left hip, THE LEFT HIP MUST CLEAR OUT to allow both arms to get to both arms straight while making room for a full roll on plane without any strange lifting or bending of the left arm as you are describing.

ALL swingers are using #4 IT IS THE MASTER ACCUMULATOR, IT must be released first it provides the main power source of the gear train. I have no idea what you mean by turning the left elbow makes it 'exert'....

Do not concern yourself with left elbow turning, focus more on the right elbow and the left hip and left wrist for proper swivel and hinge.

turning the left elbow from the top will not "help" the #3 accumulator, the only way to help or rather ensure that you get the transfer of the #3 accumulator power is to uncock the left wrist on plane and CLEAR the left hip, that is GET OUT OF THE WAY clear that left hip!
