Here’s a video going over the 3 main lower body (pivot) actions of the Driver swing.
One thing all of these players have in common is that their swings are powered from the ground-up. Despite using their bodies in completely different manners (sliding, jumping, rotating, or all three), they all initiate their downswings with their lower body. This is an unavoidable fundamental of high-level golf.
As you’ll see, the best drivers seem to get less lateral motion and more of a sit>rotate>extend sequence. A great drill to feel this is to act like you’re upper-cutting somebody with your right fist. This requires a combination of early rotation and extension through impact.
As for your own games, you SHOULD know what lower body action style you employ. If you haven’t lately, I would recommend filming a swing or two to see what you’re actually up to. As golfers, we need awareness of how our swing works as well as a couple ideas of how to make it even better through time.
