Windmill Rotation | Physio Recommendations

The Windmill Rotation assessment gives us direct insight into how spinal mobility interacts with the hips and pelvis — specifically, how well an athlete can rotate through the thoracic spine while maintaining lower-body stability.

This test is highly transferable to the golf swing. The ability to rotate efficiently around the spine — both into the backswing and through the follow-through — is a foundational requirement for power, sequencing, and consistency. The windmill allows us to see very clearly whether that capacity exists, and where it may be breaking down.

Primary Focus: Thoracic Rotation and Dissociation

The central objective of this test is to evaluate thoracic spine rotation and the athlete's ability to dissociate movement between:

• The thoracic spine (upper and mid-back)
• The lumbar spine
• The hips and pelvis

This dissociation is critical. In the golf swing, rotation should occur primarily through the thoracic spine while the pelvis provides a stable, controlled base. When that separation is limited, compensation patterns emerge — often at speed.

The windmill highlights these limitations immediately.

Common Fault 1: Hip Restriction Limiting Rotation

One of the first breakdowns you may observe is restriction at the hip that prevents the athlete from achieving adequate forward flexion to initiate the movement.

If the hips cannot hinge and flex appropriately, spinal rotation becomes mechanically restricted. In this scenario, the spine is effectively "locked" by the pelvis, and true thoracic rotation cannot occur. This athlete may struggle to even reach the start position of the test.

This is an important reminder: while the windmill is a spinal rotation test, successful execution depends on hip access and positioning.

Common Fault 2: Limited Thoracic Rotation

When hip positioning is adequate but rotation remains limited, the restriction is often occurring through the thoracic spine itself.

This may present as:

• Inability to rotate evenly to both sides
• Early lumbar compensation
• A visible "block" behind the rib cage

Asymmetries are particularly important here. Many golfers will rotate more freely to one side — often the backswing side — due to repeated exposure to that pattern. While this may appear functional in the swing, it often creates imbalance, inefficiency, and long-term stress.

The windmill makes these asymmetries obvious and measurable.

Common Fault 3: Energy Leakage Through the Lower Body

If an athlete lacks stability in the lower limbs, you may observe:

• Knee collapse
• Foot lift-off
• Loss of balance in the start position

These compensations indicate that force is leaking before rotation can even be assessed. In such cases, a low score reflects not just limited rotation, but poor force management through the entire anatomical chain.

This reinforces a key principle of assessment: rotation cannot be evaluated in isolation. The spine depends on a stable base to express mobility effectively.

Coaching Takeaway

The Windmill Rotation assessment is not just a measure of flexibility — it is a diagnostic tool for rotational control, asymmetry, and energy transfer.

By observing how the spine, hips, knees, and feet interact during this test, coaches gain actionable insight into:

• Backswing and follow-through limitations
• Side-to-side imbalances
• Compensation patterns that may emerge at speed

Use this assessment to inform both swing coaching and physical preparation. When rotation improves here, it carries over directly to improved sequencing, consistency, and durability in the golf swing.
