Windmill Rotation

Maps to Thoracic Rotation. Answers: how much usable rotation does this golfer have for the backswing, and how evenly can they access it on both sides? Rotation should come from the thoracic spine while the lower body stays grounded.

Assesses: thoracic spine mobility · lower-body stability · side-to-side symmetry. Setup: stance wider than shoulder width to lock the hips and isolate upper-body rotation.

Scoring (1–5)

Score	What You'll See
1	Rotation limited up to 90° on both sides
2	Rotation passes 135° (midway between parallel and vertical)
3	One side reaches 180°; the other remains restricted
4	Both sides reach 180° with controlled, smooth rotation
5	Both sides move freely past 180° with no visible restriction

A 4 (full rotation both sides) is the minimum standard for clean progression; a 3 (asymmetry) is common in experienced golfers.
