What is a common effect of rounded shoulders on a golfer's swing?

Rounded shoulders can significantly affect a golfer's swing, primarily by leading to difficulty in maintaining a proper posture throughout the swing. When a golfer has rounded shoulders, it alters the natural alignment of the spine and shoulders, which can compromise the stability and balance needed for an effective swing.

This compromised posture often leads to improper weight transfer and can result in an inconsistent swing path. Maintaining the correct posture is crucial because it allows for greater control over the club and ensures that the golfer can generate power efficiently while staying aligned throughout the motion. Consequently, when posture is disrupted, it impacts the overall mechanics of the swing, leading to reduced accuracy and control.

In contrast, options like improved swing plane, increased clubhead speed, and enhanced follow-through typically require a well-aligned and stable body position, which rounded shoulders can hinder, thereby reinforcing why maintaining proper posture is essential for an effective golf swing.
