THE CORE SECRET
One Simple Move for Massive Distance and Dead Aim-Putting.
▸ ENTERING PART 3
You have exposed the gaps. Now you close them.
Part 2 proved that power without support is just strain. Part 3 turns your body into a reliable machine. This is where your base becomes steady and your swing stops drifting off-line.
Stability is not a luxury. It is the anchor that allows power to exist.
You are moving from a leaking engine to a Zero Wobble Foundation.
STATUS
Ready: Your setup feels supported and your balance is quiet.
Not Ready: Your stance feels uncertain or your weight drifts under pressure.
Mission Objective: Zero wobble. Zero drift. Zero collapse.
In Chapter 6, you see why putting exposes your stability. In Chapter 7, you learn that without a brace, there is no ignition.
This is where your foundation becomes unshakable.
You may now proceed to Chapter 6.
"Stability is the quiet advantage that wins every pressure moment."
CHAPTER 6
WHY GRANDPA PUTTS BETTER
The Secret Postural Stability
Have you ever wondered why the senior golfer at your club, with his limited range of motion and "slow" swing, consistently finds the fairway and drains every putt? It is the Grandpa Paradox. While the young athlete "muscles" the club with raw tension, the veteran has accidentally discovered the secret of postural stability. This chapter introduces the Stability Anchor and the physics required to stop your swing from improvising.
Grandpa Is Steady as a Kitchen Table
You are on the green, eight feet out. You line it up, take a breath, and miss. Low, off-center, classic. Then Grandpa steps up, squints at the ball like it owes him money, and drains it dead center. No celebration, just perfect.
Grandpa’s driver barely reaches your 7-iron, but his body carries a built-in cheat code. Putting with a young, restless body is like trying to write your name on a moving bus. Grandpa is writing on a kitchen table with both elbows down. Same hands, but far better odds.
As we age, falling backward becomes dangerous, so the body adapts: a slight forward lean, abs quietly switched on, hips tucked. Not locked, just ready. It is like hovering a hand over a railing while climbing stairs: core engaged, pelvis steady, trunk quiet. He didn't plan this; his body learned it. Stability first, motion second.
>FUNDAMENTALS FIRST
Before we proceed on how to ignite and swing with the core. In each phase of the golf swing, it is vital to master the fundamentals so you won’t get lost. Imagine practicing medicine on a patient while merely guessing at the diagnosis. That is exactly what happens when you skip the mental learning.
It is the same when you fly a plane; you don’t take shortcuts. You have to study the theory so you can connect the dots in your head before you put them into practice.
If you take shortcuts here, you will only hurt yourself and potentially hurt others. You will crash your flight into inconsistency and injury.
The cockpit is prepped, the coordinates are set, and the engine is primed.
I. THE PHYSICS OF THE BRACE
Instability in the core disrupts the entire kinetic chain. Just as loose bolts weaken a high‑performance engine, poor bracing shifts mechanical stress into smaller, vulnerable joints. This triggers a domino effect of compensations where the scaffolding of your posture collapses under the speed of the swing.
Without a locked center, the rest of the swing improvises. If the first link in the chain, the Stability Anchor, weakens, every other link bends under pressure.
The Engine Analogy: A loose bolt at 100mph is a catastrophe. A loose core at 100mph clubhead speed is a slice, a hook, or a blown disc.
The Chain Reaction: When the core fails to brace, the brain sends a panic signal to the hands and wrists to save the shot. This is where Dead Aim is lost.
II. THE BIOMECHANICAL SHIELD: IAP DIAGNOSTICS
The truth is simple: No Brace, No Base. In this system, Intra‑Abdominal Pressure (IAP) functions as the structural shield that stabilizes the spine and anchors the pelvis. With a functional brace, the shield is raised, the base is secured, and every strike carries both maximum power and total protection. Without it, the body collapses, the swing breaks down, and performance fades.
THE STABILITY MAP: CORE ON VS. CORE OFF (TABLE 1)
WHY THIS DIAGNOSTIC MATTERS
IAP is the body’s internal shock‑absorber and stabilizing engine. When activated, it locks the pelvis, shields the lumbar spine, and creates a unified structure capable of producing controlled, repeatable power. When absent, the chain collapses and the swing becomes unstable, inconsistent, and physically costly.
THE CORE SECRET TRUTH
A functional brace is the difference between a body that absorbs force and a body that suffers from it. When the core is on, the entire system becomes a shield. When it is off, the system becomes exposed.
III. THE FIELD DIAGNOSTIC: TRACING THE COLLAPSE
To master the Stability Anchor, you must recognize when the stakes of your Epicenter are pulling out of the ground. When the trunk stops doing its job, every other link in the chain starts compensating under pressure.
These four Diagnostic Traces give you a field-ready checklist. Each one exposes a specific collapse pattern and gives you a concrete switch to restore the brace. Read them once. Then use them on the course as a quiet scan before you pull the trigger.
IV. THE MISSION OF PRECISION: PUTTING STILLNESS
Grandpa putts better because his Epicenter is Dead. In the short game, any movement in the core is magnified at the clubhead.
The Mechanic: A stable core prevents Trunk Drift.
The Action: Lightly brace the core before the stroke. Stillness is the hidden engine of elite accuracy.
V. WHAT HAPPENS WHEN THE CORE GOES QUIET
Every joint has a job: mobility or stability. The moment you lose the brace, the system fails. This table maps the collapse, from head to foot.
Each row in this table tells the story of how the body reacts when the engine shuts down: the head lifts because balance is lost, the neck tightens because rotation has no anchor, the lower back strains because the pelvis drifts. Every breakdown begins with the core.
Now picture the opposite: the brace holds, the spine stacks, the pelvis anchors. The head stays quiet, the upper back rotates freely, and the shoulders glide around a stable base. This is the difference you feel when ignition is on. Core in, joints aligned, swing alive.
VI. THE BIOMECHANICAL SHIELD: IAP DIAGNOSTICS
WHAT IS IT?
Intra Abdominal Pressure (IAP) is the hidden hydraulic system of the human body. Imagine a soda can: when it is sealed and pressurized, you can stand on it and it won’t buckle. That is a body with IAP. When you pop the tab and the pressure leaks, the can crushes under the slightest weight. That is a golfer with a “Core Off” setup. IAP is the internal “air cushion” that turns your midsection into a solid, unbreakable pillar.
WHY DO WE NEED IT?
The golf swing is a high velocity collision. Without IAP, your spine is the only thing holding your body together against massive rotational force. We need IAP to stabilize the vertebrae from the inside out. It acts as a biological weight lifting belt that:
Redirects Force: It moves the “hit” of the swing away from your bones and into your pressurized core.
Stops the Wobble: It secures the “Tent Stake,” ensuring your center of gravity does not shift during the strike.
Prevents the Octopus: It gives the brain the “Safety Signal” it needs to let the arms swing at maximum speed.
HOW TO USE IT:
In this system, we do not just “suck in the gut.” We create 360 degree internal expansion.
The Cinch: Pull your navel gently toward your spine to activate the deep stabilizers.
The Fill: Imagine breathing “down” into your pelvis, filling the space behind your belt buckle with air.
The Lock: Maintain that internal pressure while you exhale. You should feel wide and solid, like a pressurized cylinder.
THE STABILITY MAP: CORE ON VS. CORE OFF
The truth is simple: No Brace, No Base. With IAP, the shield is raised, the base is secured, and every strike carries both power and protection.
THE MASTER’S VERDICT: THE DIAGNOSTIC TRUTH
We no longer guess why a shot went sideways. We look at the shield. If you are experiencing Body Strain or Erratic Flight, your IAP has leaked. You have “popped the tab” on your stability.
The Check: If your follow through feels unstable, your IAP was “Off.”
The Fix: Reset the cylinder. Cinch, Fill, and Lock.
“A pressurized core is a protected core. Without the shield, you are just a crushed can waiting to happen.”
⚓ THE VERDICT: GRANDPA’S CASE
The Evidence: Stability is the hidden superpower behind consistency. IAP Diagnostics prove that an unbraced core is a Tent Stake Failure that forces the hands to rescue a collapsing frame.
The Sentence: You are sentenced to Anchor Principle Activation. You are forbidden from “muscling” the club until the base is secured.
The Ruling: When the core steadies the base, the shoulders stop guessing and the kinetic chain regains order. Precision has replaced chance.
In Chapter 7, we apply this to every phase. Without a brace, you have no base. Without a base, you have no power.

CHAPTER 7
NO BRACE NO BASE
Ignition in Every Phase
Every powerful swing begins with a stable base, but stability is not something you create at address and hope to maintain. It must be renewed in every phase of the motion. When the body loses its brace, the swing loses its structure and the club begins to wander. This chapter shows you how to build a dependable base that stays engaged from takeaway to finish, giving your swing the consistency and control it has been missing.
I. THE BIOMECHANICAL FOUNDATION: PHASES OF THE IGNITION
Understanding the mechanics of a golf swing is not just about aesthetics; it is about performance and injury prevention. To build a repeatable swing, you must understand the five primary phases of the motion and how your core protects you during each one.
PHASES OF THE GOLF SWING
FOCUS ON CORE ENGAGEMENT
Engaging the core muscles throughout the swing is the secret to stability and power. The core acts as the hydraulic fluid that connects the upper and lower body, allowing for a more efficient transfer of energy from the ground up.
IMPORTANCE OF PROPER MECHANICS
Understanding and practicing proper golf swing mechanics can help improve consistency, increase clubhead speed, and reduce the risk of strain or injury. Proper form can decrease 50–80% of the stress on the spine with every swing. Research indicates that nearly half (46.2%) of reported golf injuries occur during the swing, with 23.7% happening at the point of impact.
Researcher Insights: The Scientific Proof
The Impact Truth: Studies confirm that the downswing and follow-through are responsible for the majority of golf injuries due to the high release of energy and subsequent deceleration.
Core Stability: Experts prove that a stable core acts as the transfer point for lower-body power into upper-body acceleration, preventing energy leaks and smoothing swing rhythm.
Injury Prevention: Biomechanical adjustments can boost clubhead speed by up to 15% while simultaneously reducing injury risk.
THE CORE SECRET TRUTH
Core engagement can be described as connecting the upper and lower body, potentially allowing for a more efficient transfer of energy.
II. BEYOND THE SWING: THE SCIENCE OF UNBREAKABLE PERFORMANCE
What is this about?
This is a high precision biomechanical audit of the golf swing. It is a transition from seeing the swing as a “path for the club” to seeing it as a sequential management of internal pressure and spinal safety. It identifies 11 critical transition points from Setup to Recovery where your body either maintains its structural integrity or collapses into injury prone compensations.
Why is this important for a golfer who already knows how to play?
Even if you play well, you likely suffer from hidden power leaks and micro trauma. Most golfers chase “swing feels” that are actually just patches for a collapsing core. You need to know this because:
It Solves the “Why” of Your Bad Days: When your timing is off, it is usually because your core disengaged at the Backswing Apex or Transition Prep. Understanding these phases allows you to diagnose yourself in real time on the course.
It Ends the War with Your Spine: Golf is a high torque sport. In 2026, the leading cause of “golf retirement” is lumbar degeneration. These phases teach you how to use Posterior Pelvic Tilt and Internal Compression as a biological shield, ensuring the force goes into the ball rather than your L4/L5 discs.
It Automates Power: By mastering the Ignition Phase and Transition Initiation, you stop “trying” to hit it hard with your arms. You learn to launch the swing from a braced engine, which produces “heavy” impact and effortless distance that remains resilient under pressure.
It Builds Durability: Most golfers “collapse” the moment they hit the ball. The Post-Impact Recovery phases (Phases 8–11) are what differentiate the elite athlete from the amateur. This is how you ensure that today’s round does not prevent you from playing tomorrow.
• SETUP: Core Anchoring Begins
What it is about: The Setup is the “pre-ignition” phase where you decide if the core or the hip flexors will lead the swing. It is about establishing a Proximal Foundation before the club moves. By tucking the pelvis slightly backward (Posterior Pelvic Tilt) and stacking the ribs over the hips, you switch the core “on,” flatten the lumbar spine, and prevent tension leakage.
• BACKSWING: Deep Core Holds the Line
What it is about: In this phase, the goal is for the deep core to maintain its authority as the upper body begins a larger rotation. The body rotates around a stable, braced spinal axis. It is about Decoupling Rotation, where the upper body moves around a spine that stays stable and controlled, preventing the lumbar spine from drifting into a passive, arched state.
• II. TAKEAWAY: Bracing Against Rotation
What it is about: The takeaway is the first test of the stability established at setup. The goal is to resist unmanaged early rotation and maintain spinal integrity. It is an active phase of Controlled Resistance. It involves holding the posterior tilt and inward core brace to prevent the "Forward Drift" of the pelvis or an arching spine as the club begins its backward movement.
• BACKSWING APEX: Holding Tilt Under Load
What it is about: This is the point of Maximum Rotational Load. As the body reaches its peak turn, the risk of collapse is highest. This phase is about the deep core muscles (TVA and Obliques) bracing inward to flatten the lumbar spine and resist extension. It is the critical moment where core control prevents postural collapse and prepares for the downward launch.
• TRANSITION INITIATION: Stability vs. Collapse
What it is about: This phase captures the Tipping Point (as seen in the Rory McIlroy image reference). It is the transition from backswing to downswing where the central brace protects the spine. Without this "anchoring," the body collapses into anterior tilt, leading to "Arm-Driven Motion" and early compensations. It is a war between stability and a total collapse into "Compensatory Chaos."
• TRANSITION PREP: Core Sets the Stage
What it is about: Transition Prep is the Biomechanical Launchpad. Before the downswing begins, the core must be fully "Locked In." This phase is about a final stabilization check. Keeping the pelvis anchored and ribs stacked to ensure the following rotation is safe and powerful rather than strained and chaotic.
• IGNITION PHASE: The Point of No Return
What it is about: This is the Biomechanical Ignition. It is a fast, millisecond contraction where the pelvis tilts posteriorly, the pelvic floor lifts, and the glutes anchor the base. It is the "Core In" moment where internal compression replaces external arm chasing. This phase is "brutally honest" it rewards precision in setup and punishes those who rely on arm-driven motion with slices and chronic strain.
• ROTATIONAL DESCENT: CORE ON VS CORE OFF
• ZONE OF IMPACT: MAXIMUM COMPRESSION
What it is about
The Zone of Impact is the mechanical moment of truth where potential energy becomes kinetic force. This is not a hit; it is a release through a braced axis. At this millisecond, the body is subject to its highest level of torque and compression. If the core is “Out,” the spine buckles and power leaks into the arms. If the core is “In,” the body creates a rigid structure that allows the club to explode through the ball while the spine remains entirely shielded.
Key Biomechanics
The Final Anchor: The lead glute reaches maximum activation, anchoring the pelvis to allow for the high-velocity snap of the torso.
Max Cabin Pressure: The “Inward–Upward Vacuum” is at its tightest. This internal compression stabilizes the lumbar vertebrae against the massive shearing forces of the impact.
The Rib Lock: The ribs remain stacked and the tailbone stays tucked. This prevents Early Extension and ensures all energy is directed toward the target rather than upward into a painful spinal arch.
The Result
A strike that feels “heavy” and solid to the ball, but “light” and effortless to the body. You are not hitting with your hands; you are rotating through the ball with your entire engine.
• POST-IMPACT PHASE 1: Initial Compression
What it is about: This is the phase of Aftershock Management. Though the ball is gone, the "artillery shell" of energy is still traveling through the spine. It is about intensifying the brace as rotation slows to prevent discs from grinding "bone to bone." The pelvis remains tilted posteriorly to anchor the spine against the blast of released energy.
• POST-IMPACT PHASE 2: Rib Stack and Scapular Flush
What it is about: This phase is about Shoulder and Thorax Integrity. It focuses on the serratus anterior and scapular stabilizers locking the shoulder blades flush against the thorax. This Rib Stack prevents the scapula from flaring and ensures that the deceleration of the arms does not transfer destructive force into the spine.
• POST-IMPACT PHASE 3: Deceleration Under Load
What it is about: This is the Safeguard of Durability. As the swing comes to a final rest, the spine is under peak compression. This stage is about discipline—cinching the TVA and pelvic floor tighter rather than relaxing. It prevents hyperextension and ensures the glutes and adductors stabilize the legs as rotational energy finally dissipates.
• POST-IMPACT PHASE 4: Recovery and Structural Integrity
What it is about: This final phase is about Biomechanical Closure. The goal is for the body to exit the rotation while maintaining containment. The brace must hold until the motion is fully complete, with the spine staying neutral and the glutes active. This containment ensures the swing ends strong and the spine remains shielded, providing a finish that is strong, not strained.
III. UNDERSTANDING THE PROTOCOL: PHASE BY PHASE FOCUS
The "Ignition Protocol" suggests a focus on core engagement throughout the swing. Each phase places different demands on the spine, pelvis, and core, and understanding these demands helps maintain structure, stability, and energy transfer.
WHY THIS PROTOCOL MATTERS
Each phase of the swing requires a different level of core activation. When the core remains engaged, the spine stays protected, rotation stays connected, and energy moves through the chain without leaking. This protocol provides a structured way to maintain stability while generating rotational force.
THE CORE SECRET TRUTH
Core engagement acts as the stabilizing bridge between the upper and lower body. When this connection is active, the swing becomes more efficient, more powerful, and more structurally safe.
IV. DECELERATION SHIELD
The forces involved in a golf swing continue long after the ball has left the clubface. Focusing on core engagement during the follow‑through is discussed as potentially important for absorbing these forces and maintaining structural integrity as the body decelerates.
WHY DECELERATION MATTERS
After impact, the body must safely dissipate the rotational and linear forces generated during the swing. Proper containment during this phase may help protect the spine, shoulders, and ribcage from unnecessary stress while maintaining structural integrity through the finish.
THE CORE SECRET TRUTH
Core engagement during deceleration acts as a stabilizing shield. When maintained through the finish, it may help the body absorb force, maintain alignment, and complete the motion with control and durability. Strength in core engagement is important. When core engagement is reduced too early, the spine may become the primary absorber of force, which some sources suggest could contribute to chronic injury. Sustained core engagement until the motion is complete is discussed as important.
V. WHAT HAPPENS NEXT
The Ignition Protocol moves you from a passive participant in your swing to the Commander of your motion. This is the stage where feel meets physics. In golf, every action has a biological reaction. If you provide the correct command to your core, the body rewards you with speed and safety. If you withhold that command, the system collapses into compensatory chaos.
The following table serves as your Biomechanical Prediction Map. It outlines exactly what to do in each phase, the Win you achieve by doing it, and the Failure you risk by ignoring it. This is how you stop guessing and start executing with Intuitive Authority.
THE IGNITION BLUEPRINT: ACTION AND REACTION
THE MASTER’S EXPLANATION: WHY THE COMMAND MATTERS
We know that the brain operates on a Safety First principle. If your core is not braced, your brain will physically limit your swing speed to protect your spine.
The Chain Reaction: When you follow the What to Do column, you are sending a green light to your central nervous system. You are telling your brain, "The spine is protected; you are clear to launch."
The Rescue Operation: When you ignore the command, your body enters a Panic State. Because the base is broken, your hands and wrists have to perform a last-second rescue to find the ball. This is where inconsistency is born.
By mastering this table, you are no longer just swinging a club; you are managing a high-performance engine. You provide the stability, and the Core Secret provides the power.
“Brace harder after impact. The finish is where durability is proven. No brace, no base.”

THE CORE & GLUTE IGNITION MAP
🔗 Research
div class="enclosure">Verified, peer-reviewed research showing how maintaining a stable base and core brace throughout all swing phases enhances power, repeatability, and spinal protection.
- McGill: Core bracing stabilizes the spine under rotational load, preventing energy leaks and injury during dynamic movements.
- Chow et al.: Consistent lower body engagement improves force transfer from feet to club, supporting repeatable swing mechanics.
- Okada et al.: Integrated core and hip stabilization increases clubhead speed while reducing compensatory motions in amateur golfers.
- Hodges & Richardson: Anticipatory core activation creates a stable base for sequential limb motion, essential for precision in golf swings.
⚓ THE VERDICT: THE HYDRAULIC CASE
The Evidence: The 1.5‑Second Reality proves the brain cannot process a technical lecture mid‑swing. Biomechanical data from 2026 confirms that the Vacuum and Squeeze protocol is the only legal defense against the massive rotational forces that cause structural collapse. An unbraced finish is a confession of power leakage and an invitation to chronic injury.
The Sentence: You are sentenced to Sustained Ignition. You are strictly forbidden from releasing the core vacuum or the gluteal grip until the club has reached a complete stop and you have held the finish for three full seconds.
The Ruling: You have traded the “Octopus” for the Hydraulic Anchor. By synchronizing the Shield (Core) and the Engine (Glutes) across all five phases, you have replaced compensatory chaos with mechanical authority. Precision is no longer a guess; it is an engineered result.
In the next section, explore the concept further. This knowledge can enhance understanding of the discussed principles.
CASE CLOSED
>CODEX SOLUTIONS
What This Table Is About
The Master Code is a technical framework designed to bridge the gap between swing theory and physical execution. While many golf instructions focus on the movement of the club, this system focuses on the biometrics of the golfer. By categorizing the swing into five distinct phases, the table identifies specific rotational breakdowns and provides Ignition Cues: targeted internal commands that activate the core and glutes to stabilize and power the movement.
Core Rules
The Core Specific Action is defined by Core In and Hold. This is the foundation of all stability. For baseline control, maintain a vacuum inward and upward. If more force or speed is required, do not release; instead, squeeze and engage the core further inward. Always prioritize the inward upward vacuum to protect the spine and create a rigid axis for rotation.
Glute Rules
To effectively fire the core, you must have a stable gluteal base that tames the wobble and prevents lateral swaying. The primary glute action is to squeeze the lower glute and imagine driving that squeeze in an upward direction. This vertical engagement provides the ground force necessary to anchor your core rotations.
Rotation Rules
Rotational power is generated by the torso more than any other segment. The torso accounts for the vast majority of rotational degrees during the swing loading phase, typically 60% or more of the total rotation. Always rotate with your core on all forward rotations. By slinging the body around a braced core, you ensure the club stays on plane and the energy is transferred efficiently from the ground to the ball.
Save Your Back
To prevent long-term injury, you must shield your spine from rotational torque. Keep the core fully engaged and vacuumed inward until the swing is completely finished and no more force is felt at the finish. Never relax the core until the club has come to a total rest.
How To Use It
Analyze the Phase: Determine which part of the swing cycle is experiencing a breakdown.
Identify the Rotational Fault: Review the Rotation Problems column to understand the mechanical cause.
Apply the Ignition Cue: Choose the Core or Glute cue that addresses the fault. These are trigger words used to reset the body sequencing.
Refine Through Feedback: Use these cues to create a repeatable feel that aligns with professional swing standards.
The Master Codex Solutions
The problems outlined in The Master Codex table are the most common and significant faults in golf performance. They are difficult to solve permanently because the body instinctively creates compensatory movements to hit the ball, which ultimately leads to pain and injury in areas like the back, knees, shoulders, elbows, and wrists.
Why the Issues Keep Returning
When a golfer fixes one problem without addressing the underlying core or glute issue, they simply trade one fault for another. A golfer told to stop swaying might restrict their movement but fail to engage their lead glute, resulting in an under rotation or reverse pivot. Until the fundamental, physical limitation is addressed, the original fault will likely return.
The Compensation Cascade and Injury Risk
The body operates as a kinetic chain. If the powerful Ignition points of the core and glutes fail, the stress is absorbed by less durable joints:
Lower Back: The most common golf injury. Without a stable core and supportive glutes, the immense shearing forces are absorbed by the lumbar vertebrae, leading to chronic strain and disc issues.
Knees: The lead knee takes on significant rotational stress if hip mobility is limited.
Shoulders, Elbows, and Wrists: Without core stabilization, golfers overuse their arms for power, leading to tendonitis and impingement injuries.
Why The Master Codex is a Real Solution
The Master Codex is a real solution because it addresses the Proximal Stability for Distal Mobility principle, which is the scientific foundation of elite athletic movement. By focusing on the core and glutes the body central engine you solve the root cause of swing faults rather than just patching symptoms.
Scientific Validation & Open Access Research
The effectiveness of prioritizing core and gluteal engagement is backed by extensive biomechanical data and peer reviewed studies available through open access repositories:
Gluteal Dominance: Research confirms the gluteus maximus is the primary engine for power, showing peak activation of up to 100% during the downswing. Access the full study at the Journal of Physical Therapy Science.
The X-Factor & Torso Rotation: Open access biomechanical reviews indicate that professional level speed is a direct result of the torso rotating 60% more than the pelvis, a feat only possible with a braced core. Review the data at the Journal of Sports Science & Medicine.
Spinal Protection: Clinical evidence shows that engaging the deep core (Transverse Abdominis) provides the inward upward support necessary to reduce the shearing forces that cause low back pain. Read more on the NIH/PubMed Central Open Access archive.
Muscle Memory Permanence: Studies on motor learning suggest that proximal muscles (core/glutes) retain neural pathways longer than distal joints, making these fixes more permanent. Detailed findings are available at Frontiers in Human Neuroscience.
