What is one of the easiest ways to diagnose a loss of posture in the golf swing?

The use of the Triple Posture Line is an effective method to diagnose a loss of posture in the golf swing. This technique involves analyzing the alignment of three key points: the pelvis, the upper back, and the head. By assessing these reference points, one can determine whether the golfer maintains proper posture throughout the swing. If any of these points shift or misalign during the swing, it indicates a breach in maintaining good posture, affecting balance and swing mechanics.

Employing the Triple Posture Line provides clear visual indicators of how a golfer's posture changes throughout the swing, helping identify specific issues that may need correction. This method is particularly favored because it offers a systematic approach to gauge posture without relying solely on subjective observations or complex equipment.

In contrast, performing a full swing test may not clearly show posture issues as it primarily focuses on swing execution rather than spinal alignment. Measurement of swing speed tends to gauge the effectiveness of the swing rather than the quality of posture during the swing itself. Lastly, while visual inspection of swing follow-through can provide some insight into a golfer’s overall performance, it may not effectively identify the nuances of posture that lead to issues in the swing.
