YESChapter 15: The Strong

The core braces inward and takes command. Instead of bulging outward, it tightens and calibrates. The hips hinge back, the spine steadies, and the legs pulse with rhythm. The commander awakens, and the chain follows orders.

Force Effect: Energy contains inward, then releases outward in sequence. Nothing leaks. Every joint reports back to the core, multiplying force instead of wasting it.

Lower Group

• Foot Press through the toes with rhythm. Keep them active so balance stays alive and connected.

  Force Effect: Ground force moves upward with rhythm, feeding stability and balance.

  How to Sync it with the Core: Extend the toes and flex them lightly, play with rhythm. That wiggle before the swing is the foot reporting: "Boss, I am grounded, ready to lift the ball."

• Ankle Flex and extend with a small bounce. Keep it responsive so energy can climb.

  Force Effect: Vertical drive moves upward cleanly, without scattering sideways.

  How to Sync it with the Core: Let the ankle pulse, roll slightly, test its spring. That wiggle before the swing is the ankle reporting: "Commander, I am loaded, ready to pass it upward."

• Knee Bend softly and stay responsive. Avoid locking.

  Force Effect: Energy flows upward smoothly, syncing the lower body with the core.

  How to Sync it with the Core: Flex and release gently, keep rhythm alive. The knee wiggle is a signal: "Boss, I am flexible, ready to sync with the hips."

• Hip / Pelvis Hinge backward, sacrum dropping, pelvis balanced.

  Force Effect: Pelvic energy builds rotational power, driving the swing.

  How to Sync it with the Core: Shift the hinge, feel the sacrum drop. That subtle adjustment is the pelvis reporting: "Commander, hinge secure, rotation ready."

• Lumbar Spine Brace inward, steady and neutral.

  Force Effect: Energy transfers upward cleanly, feeding the torso.

  How to Sync it with the Core: Draw the brace inward, feel the spine steady. That adjustment is the lumbar reporting: "Boss, brace locked, no leaks."

Upper Group

• Thoracic Spine Rotate through the rib cage with steady rhythm. Keep the chest open but controlled so rotation flows upward.

  Force Effect: Rotation climbs smoothly, carrying energy into the upper body.

  How to Sync it with the Core: Breathe into the ribs, let the chest expand and contract. That subtle pre-swing lift is the thoracic spine saying: "Commander, rotation ready. I will carry your orders upward."

• Scapula (Shoulder Blades) Glide the shoulder blades so the arms stay guided, not disconnected. Keep them responsive, not stiff.

  Force Effect: Control transfers cleanly into the arms, keeping leverage alive.

  How to Sync it with the Core: Roll the shoulders lightly, feel the blades slide. That wiggle before the swing is the scapula reporting: "Boss, arms aligned, levers ready. Awaiting command."

• Arm Load the humerus, elbow, and forearm with rhythm. Keep them supple, not tense, so speed can build with control.

  Force Effect: Energy channels into the lever, preparing for acceleration.

  How to Sync it with the Core: Flex the elbow, rotate the forearm, test the lever. That small rehearsal is the arm saying: "Commander, I am loaded, I can deliver speed. Ready to snap when ordered."

• Wrist and Hand Stay loose but connected, ready to deliver precision at impact. Avoid stiffness, let the wrists pulse lightly.

  Force Effect: Snap and precision sharpen the strike, transferring energy into the ball.

  How to Sync it with the Core: Wiggle the fingers, rotate the wrists. That instinctive move before the swing is the hand reporting: "Boss, grip alive, precision ready. I will deliver the strike when you say."

• Cervical Spine (Neck) Hold steady, balancing the head so vision stays clear. Keep the neck relaxed, not rigid.

  Force Effect: Balance anchors the chain, keeping vision stable.

  How to Sync it with the Core: Tilt lightly, settle the head. That subtle adjustment is the neck saying: "Commander, vision steady, anchor secure. Ready to keep the chain centered."

• Cranial Alignment (Head) Stay centered, eyes steady, head balanced. This keeps the chain aligned from top to bottom.

  Force Effect: Anchors the top link, preventing drift.

  How to Sync it with the Core: Focus the eyes, steady the head. That pause before the swing is the cranial link reporting: "Boss, vision locked, alignment secure. Ready to follow orders."

• Breathing System Expand through the diaphragm, keep rhythm fluid. Breathing keeps tension from locking the chain. Depending on how many times you breathe before taking your shot, use those breaths to settle rhythm. On the final breath, just before you hyperfocus on the shot, engage the core inward, create intra-abdominal pressure, hold the breath in the middle of it, then fire.

  Force Effect: Rhythm spreads through the body, keeping motion alive and relaxed.

  How to Sync it with the Core: Use each breath as a rhythm check. On the final inhale, brace the core inward, feel the intra-abdominal pressure rise, then hold it steady. That pause is the breathing system reporting: "Commander, rhythm supplied, tension released, core engaged. Ready to fuel the chain."

YES Chapter 16: The Weak

The core bulges outward and loses command. Instead of tightening and calibrating, it slackens and drifts. The hips collapse forward, the spine wobbles, and the legs lose rhythm. The commander sleeps, and the chain ignores orders.

Force Effect: Energy leaks outward, scattering in fragments. Joints fail to report back to the core, wasting force instead of multiplying it.

Lower Group

• Foot Slack toes, no rhythm. Balance fades, connection weakens.

  Force Effect: Ground force leaks sideways, balance destabilizes.

  How to Fail with the Core: Toes curl inward or go dead. That silence is the foot reporting: "Boss, I lost ground, balance gone."

• Ankle Rigid or limp, no bounce. Energy stalls.

  Force Effect: Vertical drive scatters, leaking sideways.

  How to Fail with the Core: Ankle stiffens or collapses. That silence is the ankle reporting: "Commander, spring broken, drive lost."

• Knee Locked or lifeless, rhythm gone.

  Force Effect: Energy jams, breaking flow upward.

  How to Fail with the Core: Knee locks or drifts. That silence is the knee reporting: "Boss, hinge frozen, sync broken."

• Hip / Pelvis Collapses forward, sacrum rises, pelvis tilts off balance.

  Force Effect: Rotation leaks, power collapses.

  How to Fail with the Core: Pelvis drifts, hinge lost. That silence is the pelvis reporting: "Commander, rotation broken, hinge unstable."

• Lumbar Spine Bulges outward, brace lost.

  Force Effect: Energy leaks, torso destabilizes.

  How to Fail with the Core: Spine arches outward. That silence is the lumbar reporting: "Boss, brace gone, leaks everywhere."

YES Chapter 5: Structural Advantages: Reinforcing Hips and Back

Introduction

Many golfers think a golf swing is all about stronger hips, stronger leg stability, or hips, isn’t it: You see it on the range all the time. Big hip turns, backs held stiff, legs braced like pillars. It looks powerful, but the swing still feels heavy. Imagine sitting in your car, hands on the wheel, turning it left and right. It feels like control, but the car doesn’t move until the engine starts. The wheel points the way, the engine makes it go.

Golf works the same. The pelvis is that engine. When it braces inward, the swing comes alive. The strike feels solid, the ball flies further, and balance holds steady. Without it, the swing looks busy but goes nowhere, like a car with the wheel spinning but the engine off.

Core In Group

The brace surrounds the pelvis. The trunk tightens inward, the pelvis stays centered, and rotation repeats without burning out.

• Joints: Pelvis directs clean motion. Spine resists torque, knees track evenly, shoulders rotate in rhythm, wrists release without strain.
• Stability: Balance builds through the pelvis. Feet grip the ground, torso rotates without sway.
• Power: Stored torque in the pelvis unloads explosively. Energy transfers from ground to club without leakage.
• Control: Arms ride the rotation of the pelvis. Club path stays true, face squares at impact.
• Distance: Energy recycling adds carry without extra effort.
• Accuracy and Precision: Pelvis alignment keeps strikes on target.
• Ball Flight Height: Launch stays consistent.
• Force at Impact: Shock absorbed by the brace, returned through the club.
• Swinging Arm and Club Control: Arms follow the pelvis-led rotation.

Core Out Group

The pelvis is left unbraced. It shifts outward, the spine takes the load, and rotation fades too soon.

• Joints: Pelvis shifts unevenly, spine works too hard, knees compensate, wrists overwork.
• Stability: Balance slips. Feet lose grip, torso tilts, shoulders wander.
• Power: Energy leaks. Swing looks fast but delivers less force.
• Control: Arms fight to correct path. Club face opens or closes unpredictably.
• Distance: Shots shorten as energy drains.
• Accuracy and Precision: Strikes scatter without a stable pelvis base.
• Ball Flight Height: Launch becomes erratic.
• Force at Impact: Shock runs into spine and joints.
• Swinging Arm and Club Control: Arms overcompensate, timing breaks down.
