01-02: COACHES CORNER – WITH DAVID FEENEY
The ‘Flat Shoulder Plane’ occurs during the golfer’s backswing. It describes the plane of the shoulder as they get to the top of the swing. An efficient backswing will see the shoulders rotate around the spine and hence the shoulder plane at the top of the swing should see the trial shoulder be slightly higher than the lead shoulder (pic 1). Whereas in a flat shoulder plane both shoulders are almost in line and parallel to the ground (pic 2). As you can see with our model, the plane of his swing has changed dramatically, and he will have to make body and hand adjustments in order to get a good contact. Hence a flat shoulder plane has major impact on consistency and power.
