I’ve been working for the past few weeks on that conundrum (for many) – how do you start a golf swing with the setup being balanced in a certain way, with a back pivot which transitions to a weight shift into the down swing, all with a stable head position?
The answer to that question is that you can have any number of swing models that purport to solve this riddle, but that they do so using unsound mechanical principles that will a) make it very difficult to master such swings and play golf with consistency and/or b) cause injuries to the swinger ranging from joint damage and muscle/ligament strains all to the way to catastrophic spinal injuries.
