What is S-Posture in the context of swing characteristics?

S-Posture refers to a specific posture during the swing where there is an excessive arch in the lower back, creating an "S"-shaped curvature of the spine when viewed from the side. This posture can affect the golfer's ability to make a consistent and effective swing. When the lower back is excessively arched, it can lead to misalignment and potential discomfort, therefore impacting balance and the overall efficiency of the swing.

This posture is commonly observed in golfers who might not have optimal postural alignment, and it can make it difficult to achieve a proper hip turn and weight shift during the swing. Addressing S-Posture through corrective exercises and adjustments can greatly improve performance and reduce the risk of injuries related to poor posture while golfing.
