This Mobility Test Explains Your Swing #golfswing #golftips
Me and My Golf demonstrates the 90/90 mobility test to help golfers check trail shoulder external rotation relative to spine angle. The test reveals whether flexibility restrictions cause golfers to lose posture during the backswing and swing over the top. Golfers with rotation limits are advised to shorten their backswing to maintain efficiency and posture.
Assume a 5-iron posture and rotate your trail arm back to see if your forearm angle matches your spine angle.
Lack of shoulder external rotation often forces golfers to stand up and lose posture at the top of the backswing.
Losing posture in the backswing leads to compensations like swinging steep and over the top on the downswing.
If your mobility is restricted, adoption of a slightly shorter backswing will help you stay in posture and hit better shots.
