Thank you, Golfbulldog. Let's go one step further and put up Exercises #3 and #4. These constitute a pure TGM Pivot.
Note the Centered Head in #3.
Note the Centered and Turned Head in #4.
Note the Flat Backstroke Hip and Shoulder Turns in #4 and especially the absence of Backstroke Shoulder Turn "pie" (inclination of the back from the vertical).
This is the Pivot I teach and have taught since 1982, regardless of misrepresentations to the contrary.
Per Homer Kelley:
1-L-#1 "The Stationary Post (Player's Head) accurately returns the Clubhead to the Ball."
1-L-#2 "The Post may turn (Pivot) but it does not Sway or Bob."
will do it tonight - will try to get better pics this time - or mayb "putfile" is losing some details in the download... i can read the print in the priginal photos...
