longitudinal center of gravity <~~ sorry what is this please?

and why swinger use longitudinal acceleration ? not rotation? I thought swinger use rotation because of centrifugal force? QQ

Thank you so much !

If you hold the butt end of the club and also hold a string against it with a weight attached by your fingertips - you will find it will travel directly to the sweetspot - This is the longitudinal center of gravity.... - in practical terms it means you always point the sweetspot at a straight line back from the ball - the shaft rotates around the sweetspot and not vise versa.....

The left arm and clubshaft is driven into impact by pivot thrust in the swingers procedure which means the hand will still be turned to the plane until the powers that be rolls the left hand back to vertical ...left arm karate chop - rope handle technique....
