Keep the head steady in the backswing — it’s the shoulders that do the work Rather than letting your head sway laterally, focus on turning your lead shoulder towards your trail foot to load weight into your right heel without your head moving more than half an inch.
At the start of the downswing, allow a slight dip The best ball-strikers drop their head just a touch as they shift weight into a small squat on the front leg — this is the only deliberate up-and-down head movement you want to introduce.
Keep your head behind the ball through impact to create separation Your hips should lead through the “magic line” at impact while your head stays back, creating the separation between upper and lower body that generates power — moving your head forward kills that separation entirely.
