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.
