The podcast presents a methodology for classifying golfers into nine core body regions based on body measurements to optimize swing technique for greater power and consistency. A special focus is placed on the Middle Core Golfer—a hybrid type that combines traits of both the Upper and Lower Core regions, using what is often called the “Gold Standard Swing.” The swing mechanics of this type are explained in detail, including grip, stance, backswing, downswing, and balance, with comparisons to Upper and Lower Core golfers. Examples include PGA Tour players like Adam Scott and Ernie Els. The analysis is based on 25 years of research.

The Middle Core region spans from the navel to the base of the sternum and reflects a balanced blend of Upper and Lower Core characteristics.

Key swing traits of Middle Core Golfers:

• Stance Width: Intermediate—wider than Upper Core, narrower than Lower Core.

• Grip: Neutral grip, with the grip crossing the first knuckle of the middle finger in both hands.

• Body Angles: Spine-to-femur angle ranges from 152.5° to 158.5°, typically 154°–156°.

• Backswing: Initiated by the upper body (shoulders, arms, and hands), followed by the hips. Hip rotation is moderate. The lead knee points behind the ball; the shoulder plane stays neutral. The right hand rests on the side of the grip, and the right forearm is vertical or slightly outward.

• Downswing: Begins with hip and shoulder rotation, followed by arms and hands. The shaft intersects the Middle Core and points to it at impact. The right elbow stays near the right hip. Hips rotate 45–60% toward the target, and energy is released diagonally (45°) across the target line. The shaft points to the golfer’s core, similar to Adam Scott and Ernie Els.

• Balance: Weight stays slightly forward of the arch centers, behind the balls of the feet. Ball position is centered.

• Power Sources: All three force types are used—linear, rotational, and vertical.

• Power Angle: Matches stance width—between 152.5° and 158.5°.

In summary, the Middle Core swing is a hybrid that blends the control of the Upper Core and the power of the Lower Core. Body, arms, and hands work in unison. Top Middle Core golfers include Adam Scott, Jon Rahm, Jason Day, Cameron Champ, Ernie Els, and Justin Thomas. Most LPGA players are Middle or Lower Core. These players show a mix of core traits and often feel centered over the pelvis in the backswing and experience a slightly upward, rotational release through impact—with minimal lateral motion.
