Thanks Todd. To be clear let me ask you... is extensor action the principle of having a straight left arm throughout the swing by means of extending (continuously) the right arm to insure it remains straight? So is that to say that attempting to keep the left arm straight by using the left arm as the means to do so is an impractical and ineffective way of doing it (am I making any sense?)?
The obvious thing for most anyone trying to accomplish a straight left arm would be just to focus on doing that so there must be benefit to using the right arm.
Thnaks again,
Michael
Michael,
The straight left arm in my opinion becomes a hyperextended left arm when done with only the left arm. Extensor action stretches but does not move the left arm, the benefit of the right arm or trail arm (for the benefit of Philly) is the added structure. Golfers continue to allow acceleration and impact to derange their structure, the resistance to deceleration is lost, never to be regained. Extensor action provides for the checkrein action of keeping the right arm from straightening too soon, providing a smooth even thrust of the lever assemblies into followthrough.
Extensor action also provides structure in that it keeps the radius of the primary lever the same as it was established at impact fix. No shortening of the radius for those with exstensor action.

A core difference between trying to 'keep the left arm straight' and extensor action (using the right arm to extend the left) is Rhythm, Rhythm, Rhythm!
The physics involved help the right side 'support' impact at exactly the right time - with the proper rate of clubface closing/motion - the proper amount of rotation. This GREATLY aids in consistency and supports full BALANCE, making it dramatically simpler to maintain. As another benefit, this all adds up to the 'heavy', 'smooth' motion feeling.
Not to mention the ability to maintain a flat lead wrist is just another, important BONUS
Percy Boomer understood this well.
