Hip internal rotation is one of the most important—and most misunderstood—physical abilities in golf. In this episode of the Golf Fitness Bomb Squad, Chris Finn takes a deep dive into the hip internal rotation test, why the 45-degree benchmark matters, and what it really means for your golf swing, your speed, and your long-term health.

Chris breaks down:

How to properly perform the seated hip internal rotation test
Why failing this test is the number one predictor of low back pain in golfers
How limited hip rotation forces compensations in the spine, knees, and swing mechanics
The connection between hip mobility, ground reaction forces, and clubhead speed
Why stretching alone doesn’t fix the problem—and what actually does
A step-by-step framework to improve hip rotation safely and permanently

From everyday golfers to long-drive champions, this episode explains why hip internal rotation affects pain, power, and consistency, and how addressing it can help you swing faster, protect your back, and play golf longer.

If you care about longevity, speed, or staying healthy in golf, this is an episode you don’t want to skip.
