It is true that Extensor Action can be exaggerated into an immobilizing fault. However, that does not obviate its necessary purpose; namely, to provide a "structural rigidity" that is a strong deterrent to collapse under the stresses created by a powerful golf stroke, especially at the Top and through Impact.

To achieve maximum Zone 2 Power, the Arms (and with them the Club) must swing freely from the Shoulders (and not be bound to and drug around by them). Also, the Wrists must remain flexible to perform their Release functions (Uncock and Roll). However, that does not mean that the Power Package Structure (which these Components and their Loading collectively comprise) should be "loose" or, worse yet, "flimsy". Or that the Hands should be robbed of the firm Grip necessary to control Clubface alignments.

Just as there are good and bad cholesterols, so are there good and bad tensions in the Golf Stroke. Differentiating the two distills the champion.

It has never been made clear to me which tricept muscle('s) are active for EA.

Just as bicept curles can be performed pronate or supinate so and use DIFFERENT bicept muscle, A tricept push down can be done pronate or supinate and use DIFFERENT tricept muscle. One way creates no control but great tension the other creates "structure" and frees the wrists and power package from tension. Which does what and how is EA properly applied. This requires more description than "stretching" . HOW not WHAT.? I believe this is KEY.
