Windmill Rotation Test
Assessing rotational movement patterns and range of motion as a measurable assessment of rotation in the golf swing.
The movement
Two phases, one connected system
Scrub the rep above to move between the two positions, or tap a phase to hold it.
Wide stance, rotate through the thoracic spine and reach the hand toward the opposite foot.
Mirror the reach to the other side — checking matched rotational range left and right.
Fundamentals
What the test is really measuring
Thoracic rotation
Quality and range through the thoracic spine is a key driver of rotational potential — and reduces injury risk.
Body symmetry
Any left/right difference in rotational capacity. The swing is asymmetrical, so most golfers carry imbalances worth tracking.
Neutral hips
The wide stance tests lower-body stability — a neutral pelvis shows true separation and control.
Centre of gravity
Rotating around the spine within your base of support — a fundamental swing pattern tested objectively.
Power potential
Full thoracic range increases power through club arc, rotational coil and loading the torso against the trail leg.
Scoring
Score it 1–5
Mobility screens are scored on a 5-point quality scale — five tests combine into your mobility category, half of the Golf Fitness Handicap™.
5 / 5Full thoracic rotation with matched range left and right, hips held neutral and stable through the turn.
90 degree windmill range
135 degree windmill range
180 degree windmill range on one side
180 degree windmill range on both sides
181 degree or greater windmill range
Why it matters
Unrestricted rotation, a wider, fuller backswing.
Unrestricted rotation lets a golfer create a fully loaded, wide backswing — enhancing their ability to build optimal swing mechanics and desired impact factors.
