The twirl is a purely circular motion of the clubhead around the point of the arm shoulder triangle at the wrist joints. Due to its circular nature it produces much speed similar to the way we can make a keyring gain speed as we twirl it. The speed of the clubhead created by the circular twirl of the clubhead around the hands is combined with the speed created by the circular motion of the point of the arm shoulder triangle at the wrists as the hands are rotating around the swing circle center.
Thus the twirling hands are returned to and through impact powered by the weight shift and the hip turn. Due to the perfect control of the path and the plane created by our leg and hip actions the center of the rotation of the twirl is perfectly controlled as it is directed and powered around the swing circle center by the pivot. Together these 2 speeds, combine to provide rapid clubhead speed with very little application of effort. In the words of Mike Dunaway \”You get more out of less with this swing than with any other way of swinging the club\”. He could not be more right.
The twirling action of the club is felt to be a rotation of the two lower bones of the right forearm, however it triggers the action of many other right arm movements. Remember that all of the muscles that we will use on the down swing are stretched by the motions we make as we swing back, thus they are ready to reverse the actions as we swing down simply by contracting.
This contracting action will happen in the perfect sequence and at the exact right time and place in the downswing if we correctly trigger the start of the motion. Especially important in the backswing is the counter-rotation of the forearms which positions the right hand as if we were holding a plate of spaghetti on a small tray. This action correctly winds up the forearm bones, stretching additional muscles that we can use to add clubhead speed.
These additional muscles are very quick acting small muscles that cause the club to rotate around the wrists in a true circular motion relative to the point of the arm shoulder triangle. As you know this point is independently driven around the swing circle center by the pivot, together these 2 coinciding circular motions create much power and the precise swing plane, clubhead path and clubface control. Done correctly these actions are the true secret to the formula for power and accuracy.
The trigger that starts all of these actions is a light push of the right thumb to begin the clubhead rotation of the twirl as the hips slide left caused by the actions of the feet and knees that starts the pivot. Correctly done all of the effort of the golf swing is done in the first 2 feet of the downswing, from there the swing freewheels as the contraction of the stretched muscles combine with centifugal force and gravity to provide enormous power and a precisely controlled clubface ball contact.
