This 2025 podcast excerpt focuses on inconsistent club paths in the golf swing and introduces four measurable data points to improve performance. These metrics include the distance between the club and hands at two key swing positions, the shaft angle relative to the shoulder plane, and the swing direction relative to the stance line. By tracking these values using video analysis, golfers can refine their takeaway, swing top, and downswing to create a more consistent and effective club path for improved shot accuracy.

The four key measurements for club path consistency are designed to address the following common swing issues:

• Inconsistent Club Path: The main issue is a club path that lacks repeatability. Measuring the club-hand gap at the P2 position (takeaway) and the P4 position (top of the swing) helps keep the club on a consistent path.

• Swing Plane Issues: Measuring the shaft angle relative to the shoulder plane at the top of the swing helps identify and fix positions where the club is too “laid off” or “across the line” compared to address. This contributes to a more consistent downswing plane.

• Inconsistent Start Direction and Shot Shape: A variable club path is a primary cause of erratic start directions and ball flight curves. Measuring swing direction in relation to the stance line supports a neutral or slightly in-to-out path, promoting straighter, more predictable shots. Extreme paths can result in pushes, pulls, hooks, or slices.

• Lack of Repeatability and Precision in Ball Striking: By measuring and correcting these four data points, the swing becomes more refined, leading to better ball striking. A more consistent club path and improved swing plane help golfers strike the ball more cleanly and with the intended trajectory more often.

In summary, these four key measurements help quantify and optimize fundamental aspects of the club path, enabling a more consistent, repeatable swing that results in more accurate shots with the desired direction and shape.

The Universal Swing Score by Sportsbox AI objectively evaluates the quality of a golf swing on a scale from 1 to 100. It is based on three main categories — Speed, Efficiency, and Consistency — and was developed to directly link swing mechanics with actual performance on the course (such as scoring average or handicap). The system uses a comprehensive database of over 250 different swings, categorized by club type, gender, and skill level.

In the Speed category, key metrics include rotational range of motion (chest, pelvis, X-factor), horizontal and vertical movements (slide, drop, lift), rotational speeds (°/sec), and release timing and angles. The goal is to precisely measure a player’s potential to generate clubhead speed.

The Efficiency category evaluates how effectively energy is transferred through the body to the club. Key data points include the kinematic sequence (pelvis → chest → arms → shaft), peak segment speeds, gain factors between body segments, and each segment’s contribution to clubhead speed. The transition order and the pelvis movement sequence (slide, turn, lift) are also analyzed.

Consistency measures how repeatable a player’s swing is across multiple attempts — the lower the standard deviation, the better. The score tracks rotation metrics, body positions, and timing of transitions between pelvis, chest, arms, and shaft. At least three swings are required, with ten or more preferred for better accuracy.

The results are visualized in reports and the app using color codes (green, yellow, red), Z-scores, and graphical comparisons. Each player also receives a two-letter swing type, based on their dominant movement direction (e.g., rotational) and main power source (e.g., core).

The Universal Swing Score offers a clear, data-driven benchmark for swing quality, giving players and coaches actionable insights for improvement.

This text introduces the Core-Zone System, a biomechanically-based model that classifies golfers into Upper Core, Mid Core, and Lower Core types. It explains how grip technique, stance, swing mechanics, and course management should be adapted to the player's core type to optimize performance. Functional tests help determine the core zone, with emphasis on grip pressure, breathing, and physical asymmetries. The aim is personalized instruction aligned with natural movement patterns.

A golfer’s individual body mechanics heavily influence their ideal swing and strategy. The system identifies three dominant core regions—Upper, Mid, and Lower Core—that dictate how players generate power, maintain balance, and move the club.

Key Influences on Swing and Strategy:

• Grip:

  • Upper Core: Light grip on first pad, neutral wrist. Promotes early rotation and arm-body connection.

  • Mid Core: Grip across hand center. Promotes synchronized torso-arm movement.

  • Lower Core: Grip deep in the palm, strong hold. Enhances grounded setup and rear-side load.

  • Grip choice affects balance, energy transfer, and must fit body mechanics.

• Setup and Stance Width:

  • Upper Core: Ball of the feet, 8–16 inches stance.

  • Mid Core: Over arches, 10–18 inches stance.

  • Lower Core: Heels/posterior chain, 12–20 inches stance.

  • Setup must reflect the natural balance point to avoid rotation loss and swing faults.

• Swing Sequencing:

  • Upper Core: Initiates with trail hip, early torso rotation.

  • Mid Core: Synchronized torso and hips.

  • Lower Core: Initiates with shoulder turn, builds power from ground tension.

• Grip Pressure, Breathing, Rotation:
  Ideal grip pressure: 2–3/10. Correct breathing improves rotation and stability under pressure.

• Carrying Angle and Asymmetries:Proper angles (e.g., ~157° for Mid Core) and recognition of body asymmetries enhance consistency and motion freedom.

Impact on Course Management:

• Upper Core: Precision, short clubs, aggressive lines. Under pressure: reduce grip pressure, sharpen focus.

• Mid Core: Balanced rhythm, structured plans. Under pressure: trust flow, avoid overthinking.

• Lower Core: Strong with long clubs, excels in wind. Under pressure: deepen setup, trust body strength.

Summary:The Core-Zone System shows that body mechanics—not general templates—should guide grip, setup, sequencing, and strategy. Golf instruction must respect the player’s natural movement blueprint for maximum performance.

In dieser Podcastfolge mit dem Titel „Der Upper Core Golfer“ werden Forschungsergebnisse über neun verschiedene Core-Regionen des Körpers und deren Einfluss auf den Golfschwung vorgestellt. Die zentrale These lautet, dass die Standbreite eines Golfers entsprechend seiner Core-Zuordnung angepasst werden kann, um Kraft und Konstanz zu optimieren. Der Schwerpunkt liegt auf dem sogenannten Upper Core Golfer (Regionen 7, 8, 9), dessen Griff, Setup, Rückschwung und Abschwung in Bezug auf Gewichtsverteilung und Körperwinkel detailliert beschrieben werden. Bekannte Profis, die diesem Typ entsprechen, dienen als Beispiele. Der „Upper Core Golf Swing“ wird vor allem durch die verwendete Körperregion und deren spezifische Bewegungsmuster definiert.

Zu den Core-Regionen:

Die Upper Core Region umfasst den Bereich vom Beginn des Brustbeins bis zum Hals.

Golfer dieser Kategorie werden als Hand-/Arm-Golfer bezeichnet, da ihr Schwung in hohem Maße durch Hand- und Armbewegungen gesteuert wird.

Zur Nutzung dieser Region und den daraus resultierenden Schwungeigenschaften:

• Upper Core Golfer verwenden die schmalste Standbreite aller Core-Typen.
• Sie zeigen beim Setup den geringsten Schaftwinkel nach vorn; der Schaft zeigt fast zur Innenseite der linken Hüfte. Dies resultiert aus einem schwachen Griff.
• Der Griff wird als Long Thumbs bezeichnet, wobei der Schaft auf dem ersten Knöchel des Mittelfingers an der Handinnenfläche beider Hände liegt – eine typische Position für einen schwachen Griff.
• Im Setup liegt der rechte Arm entlang des Brustkorbs, der rechte Ellbogen befindet sich leicht außerhalb der rechten Hüfte.
• Beim Messen der Körperwinkel ergibt sich ein deutlich größerer Wirbelsäulenwinkel im Vergleich zum Oberschenkelknochenwinkel. Der Femurwinkel beträgt im Setup mindestens 159 Grad.

Rückschwung:

Der Rückschwung beginnt mit einer gleichzeitigen Rotation von Hüften und Schultern.

Am höchsten Punkt des Rückschwungs zeigen Upper Core Golfer die größte Hüftrotation und die geringste Separation zwischen Ober- und Unterkörper. Die Schulterebene ist nahezu senkrecht.

Der Körperschwerpunkt verlagert sich zur linken Seite. Der rechte Ellbogen zeigt nach außen – eine Position, die oft als Flying Elbow bezeichnet wird.

Abschwung:

Im Abschwung befinden sich Upper Core Golfer bereits auf ihrer linken Körperseite und leiten die Bewegung mit Schulter- und Hüftrotation ein.

Der rechte Ellbogen bleibt während der gesamten Bewegung außerhalb der rechten Hüfte.

Im Treffmoment rotieren die Hüften nur leicht, da der Spieler den Körper aufrichtet und das Gewicht auf die Fußballen verlagert.

Arme und Hände führen die Bewegung an und schwingen schnell nach links, wobei der Schläger auf den oberen Brustbereich zeigt.

Das Beibehalten der Körperwinkel im Treffmoment kann zu einem Kraftverlust führen.

Balance und Bodenkraft:

Die Balance im Setup liegt auf den Fußballen.

Upper Core Spieler nutzen vor allem Rotations- und Vertikalkräfte aus dem Boden. Ihre Bewegung enthält kaum lineare oder horizontale Kraftkomponenten.

Spannung auf der linken Körperseite entsteht durch die starke Rotation der rechten Hüfte und den nach außen gerichteten rechten Ellbogen im höchsten Punkt des Rückschwungs.

Ein zentrales Gefühl für Upper Core Golfer ist das „Abdecken des Balls“ bzw. das bewusste „Freigeben“ von Armen und Händen.

Zusammenfassung:

Der Upper Core Golfschwung ist geprägt durch den dominanten Einsatz des Oberkörpers – Hände, Arme und obere Brust. Er zeichnet sich durch einen schmalen Stand, einen schwachen Griff sowie spezifische Muster in Hüft- und Schulterrotation aus.

Diese Spieler erzeugen ihre Kraft primär durch rotierende und vertikale Bodenkraft und neigen dazu, sich im Treffmoment aufzurichten.

This Podcast, titled “The Upper Core Golfer,” presents research on nine different core regions of the body and their influence on the golf swing. It argues that a golfer’s stance width can be adjusted based on these regions to optimize power and consistency. The text focuses specifically on the "Upper Core Golfer" (Regions 7, 8, 9), describing their unique grip, setup, backswing, and downswing characteristics, including weight distribution and body angles, and referencing well-known golfers who represent this type. According to the sources, the "Upper Core Golf Swing" is primarily defined by the body region used and its specific movement patterns.

Regarding the Core Regions:

• The upper core region includes the area from the start of the sternum to the neck.

• Golfers in this category are referred to as "hand/arm golfers," indicating that the swing is heavily driven by hand and arm movements.

Concerning the Use of This Region and Resulting Swing Characteristics:

• Upper Core golfers use the narrowest stance of all core types.

• They exhibit the least shaft lean at address, with the shaft pointing nearly toward the inside of the left hip. This minimal shaft lean results from a weak grip.

• Their grip is described as “long thumbs,” where the shaft rests on the first knuckle of the middle finger next to the palm in both hands. This is considered a weak grip position.

• In the setup, the right arm rests along the side of the rib cage, and the right elbow is positioned slightly outside the right hip.

• When measuring body angles, there is a much greater spine angle compared to the femur angle. At address, the femur angle is at least 159 degrees.

Backswing:

• The backswing is initiated by simultaneous rotation of the hips and shoulders. At the top of the backswing, Upper Core golfers show the greatest hip rotation and the least separation between the upper and lower body. The shoulder plane is vertical. The center of mass shifts to the left side. The right elbow flares outward at the top of the backswing, a position often referred to as the “flying elbow.”

Downswing:

• In the downswing, Upper Core golfers are already positioned on their left side and begin the motion with shoulder and hip rotation. The right elbow remains outside the right hip throughout.

• At impact, the hips rotate only slightly, as the player straightens the body and shifts weight onto the balls of the feet. The arms and hands lead the motion and swing quickly to the left, with the club pointing toward the upper torso. Maintaining body angles at impact can lead to a loss of power.

Balance and Ground Forces:

• Balance at address is distributed over the balls of the feet. Upper Core players utilize rotational and vertical ground forces. Their motion contains minimal linear or horizontal force. Tension on the left side of the body is generated by the deep rotation of the right hip and the outward-facing right elbow at the top of the backswing.

• A key sensation for Upper Core golfers is "covering the ball" or the "release" of the arms and hands.

In summary, the Upper Core Golf Swing is characterized by dominant use of the upper body (hands, arms, upper chest), a narrow stance, weak grip, and specific hip and shoulder rotation patterns. These golfers rely heavily on the power generated from rotational and vertical ground forces and tend to straighten up at impact.

Der Podcast stellt eine Methodik vor, bei der Golfer anhand von Körpermaßen in neun Core-Regionen eingeteilt werden, um die Schwungtechnik für mehr Kraft und Konstanz zu optimieren. Im Fokus steht der Middle Core Golfer – ein Hybridtyp, der Merkmale der Upper und Lower Core-Regionen vereint und häufig den sogenannten „Goldstandard-Schwung“ nutzt. Die Schwungmechanik dieses Typs wird im Detail erläutert, einschließlich Griff, Stand, Rückschwung, Abschwung und Balance – mit Vergleichen zu Upper und Lower Core Golfern. Als Beispiele werden PGA-Tour-Spieler wie Adam Scott und Ernie Els genannt. Die Analyse basiert auf 25 Jahren Forschung.

Die Middle Core Region erstreckt sich vom Bauchnabel bis zur Basis des Brustbeins und vereint ausgewogen die Eigenschaften von Upper und Lower Core.

Wesentliche Merkmale des Middle Core Golfers:

• Standbreite: Mittel – breiter als beim Upper Core, schmaler als beim Lower Core.
• Griff: Neutraler Griff, der den ersten Knöchel des Mittelfingers beider Hände kreuzt.
• Körperwinkel: Der Winkel zwischen Wirbelsäule und Oberschenkelknochen liegt zwischen 152,5° und 158,5°, typischerweise bei 154°–156°.
• Rückschwung: Wird durch den Oberkörper (Schultern, Arme, Hände) eingeleitet, gefolgt von den Hüften. Die Hüftrotation ist moderat. Das vordere Knie zeigt hinter den Ball, die Schulterebene bleibt neutral. Die rechte Hand liegt seitlich am Griff, der rechte Unterarm steht senkrecht oder leicht nach außen.
• Abschwung: Beginnt mit der Rotation von Hüfte und Schulter, gefolgt von Armen und Händen. Der Schaft durchquert die Middle Core-Region und zeigt im Treffmoment auf diese. Der rechte Ellbogen bleibt in der Nähe der rechten Hüfte. Die Hüften rotieren 45–60 % in Richtung Ziel, die Energie wird diagonal (45°) über die Ziellinie freigesetzt. Der Schaft zeigt auf das Körperzentrum – ähnlich wie bei Adam Scott oder Ernie Els.
• Balance: Das Gewicht bleibt leicht vor dem Fußgewölbe, hinter dem Fußballen. Die Ballposition ist mittig.
• Kraftquellen: Alle drei Kraftarten werden genutzt – linear, rotierend und vertikal.
• Kraftwinkel: Entspricht der Standbreite – zwischen 152,5° und 158,5°.

Zusammenfassung:

Der Middle Core Schwung ist ein Hybrid, der die Kontrolle des Upper Core mit der Kraft des Lower Core vereint. Körper, Arme und Hände arbeiten synchron. Führende Middle Core Golfer sind u. a. Adam Scott, Jon Rahm, Jason Day, Cameron Champ, Ernie Els und Justin Thomas. Die meisten LPGA-Spielerinnen gehören zum Middle oder Lower Core. Diese Spieler zeigen eine Mischung aus Core-Merkmalen, fühlen sich im Rückschwung zentriert über dem Becken und erleben einen leicht nach oben gerichteten, rotierenden Treffmoment – mit minimaler seitlicher Bewegung.

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.
