What does loss of posture refer to in the context of a golf swing?

Loss of posture in the context of a golf swing refers to a significant alteration from the body's original setup angles. This concept is critical because maintaining proper posture throughout the swing facilitates a consistent and effective motion. When a golfer loses their posture, it can lead to a range of issues, including improper alignment, reduced swing efficiency, and increased risk of injury. The original setup angles are designed to create an optimal balance and position for the golfer, which is essential for executing a solid and repeatable swing. Maintaining these angles helps ensure that the swing path, body rotation, and weight transfer occur as intended, resulting in better overall performance.
