What is the effect of early extension on a golfer's swing performance?

The effect of early extension on a golfer's swing performance is primarily that it reduces the efficiency of the motion. Early extension occurs when a golfer's pelvis moves toward the ball during the downswing, rather than maintaining its position. This movement can disrupt the proper sequence of the swing, leading to a loss of posture and balance. As a result, the golfer may struggle with consistency in their swing path and face alignment at impact, which ultimately affects the overall efficiency of the swing.

When the swing becomes less efficient, the golfer may expend more energy without achieving optimal results, which can lead to increased slices or hooks due to improper clubface alignment. This decrease in efficiency can manifest as a loss in distance and control, making it critical for golfers to address and maintain proper posture throughout the swing. Understanding the implications of early extension helps golfers work on their mechanics, ensuring they can achieve a more fluid and powerful swing.
