Touch under your trail knee to check impact tilt
Craig Hanson offers an impact checkpoint: move into your impact position and try to touch underneath your right (trail) knee, going as far as your flexibility allows. Reaching that far gets your shoulders into a good area, roughly 30 to 35 degrees of tilt, which he cites as the PGA Tour average. Use it as a static checkpoint you can return to between practice swings.
