When does early extension typically occur in a golfer's swing?

Early extension in a golfer's swing typically occurs when the hips and spine begin to straighten too early during the downswing. This movement disrupts the proper sequence of the swing and causes the golfer to lose their posture, which can lead to inconsistencies in striking the ball effectively. When the hips extend prematurely, it can result in a loss of power and accuracy, as the golfer may stand up instead of maintaining the correct spine angle, which is essential for a solid and powerful strike.

In contrast, other phases of the swing, such as when the shoulders lose stability or during the follow-through, do not define the phenomenon of early extension. Likewise, the initiation of the backswing does not typically relate to this issue because early extension occurs more critically during the transition and downswing phases. Recognizing the specific timing and mechanics of early extension helps golfers to focus on maintaining their posture and maximizing their swing efficiency.
