What can a forward head position with rounded shoulders at address cause?

A forward head position with rounded shoulders at address can lead to an "over the top" swing. This refers to the swing path where the club moves outward during the downswing rather than from the inside. This position often results from the body's misalignment, causing players to compensate during their swing.

When the upper body is collapsed forward, the golfer may struggle to maintain a proper swing plane, which can lead to the club traveling outside the desired path. The combination of the head moving forward and the shoulders rounding can restrict natural body rotation, making it difficult to achieve a proper follow-through. The "over the top" swing is commonly associated with slices and pulls, leading to inconsistent shots and potential errors in ball striking.

In contrast, a stable address position, where the head and shoulders are aligned properly, supports a more effective swing path and promotes better ball contact and increased stability. However, the positioning indicated in the question primarily disrupts this alignment, culminating in the over the top motion.
