30-minute routine
5 minutes of warm-up, 10 minutes of contact calibration, 10 minutes of tee-shot or approach dispersion, and 5 minutes of one-ball pressure practice.
60-minute routine
10 minutes warm-up, 15 minutes wedge calibration, 15 minutes target-specific approach shots, 15 minutes tee-shot dispersion, and 5 minutes review.
90-minute routine
Add variable targets, a driver-versus-safer-club test, and a scored nine-shot finish. Break the session into clear blocks and pause briefly between them.
The range is not the whole game
Putting, short game, on-course decisions, and post-round review may be a better use of part of your week. Your plan should reflect the strokes you actually lose.
