Create speed top-down: shoulders lead, hips follow
A sequencing and speed mental model: think about creating speed top-down. The coach describes the shoulders as the faster movers and the source of clubhead speed, with the hips as 'enablers' or accessories that respond. The faster he gets his shoulders through, the faster he swings, and the hips then fire on their own. The takeaway is to lead with the shoulders through the ball rather than trying to consciously time the hips.
