[O.B.Left]

Stay with half swings for awhile. Equal length in both directions, Right Forearm parallel to the ground in the backstroke, then left forearm parallel into the finish. Point the butt end of the club at the line (again, in both directions). Keep the motion continuous -- back and through and back and through. Let the left wrist roll to plane and recock into the finish. Let the club swing free.

Grant don't miss this point Ive put in bold above. You will not Bob while doing so . With a line of balls in front of you (after some prior training) these little half swings , Acquired Motion , will find the sweet spot magically. You'll have to learn how to not interrupt the motion with a hit at the ball impulse. Lag and drag in both directions. Brush the ground in both directions. Let er flow. Wild Bill Melhourne style. Let the motion make the shot . Impact does not rank as one of golfs three stations ..... make no adjustment for impact etc etc.

You'll find that this motion will create the positions you seek , not vice versa.

P.S. Once you feel the magic in this drill , the way the sweet spot finds the ball when theres a feel of lag pressure, know that Total Motion is only a slightly longer backstroke away. Top is only inches away from Acquired's right arm parallel to the ground. Its way easier and quicker to learn this stuff in Acquired Motion than in Total Motion. Total Motion often being exaggerated to a fault making the self discovery of lag and drag highly unlikely.
