For the Hitter's application, start from the Swinger's position Luke has described above. Now, Roll the Left Wrist slightly (to the left toward the vertical). Allow the Right Forearm Flying Wedge to likewise Roll. Now observe the position of the Right Elbow. You are in Punch.

In other words, Single Wrist Action will naturally bring your Elbow to a Punch position, while Standard Wrist Action will naturally bring it to a Pitch position.

Another reason for the Swinger to Start Up Swivel.
