Boost Stability and Power with the Anchor

One of the most pervasive swing faults affecting millions of golfers is the tendency to come out of posture — or lose spine angle — during the downswing. This movement pattern, commonly known as “early extension,” does far more than simply compromise accuracy and distance. It actively robs the golfer of both control and power, while significantly increasing the risk of injury in the lead hip and lumbar spine (lower back).

The unfortunate reality is that most golfers — and even many instructors — fail to grasp the true biomechanical causes behind this widespread fault, let alone how to correct it. Before we can address the fix, we need to understand what proper movement looks like when executed correctly, viewed from a revealing angle.

In the photo sequence below, we see footage of Tiger Woods striking a three wood. The image on the left captures Tiger after he has already initiated the club’s descent during the downswing. What deserves particular attention here is that BOTH knees still maintain significant knee flex at this stage of the motion.

In the second photo, observe how Tiger’s belt has risen considerably above its position during the transition (indicated by the yellow line), producing an almost jumping appearance — all while preserving the flex in his trail knee throughout the entire movement.

For the vast majority of amateurs, the glutes — the most powerful stabilizing muscles in the lower body — never get properly loaded during the downswing the way Tiger achieves by “squatting” during the transition. This squatting motion represents a tremendous source of both power and stability. In fact, many golfers fully straighten the trail leg before they even complete their backswing, eliminating any chance of engaging these critical muscles.
