• #383 Golf Impact P7 by Core Type
    2025/10/20

    P7—the moment of impact—is the defining instant of every golf swing. It determines strike quality, ball flight, and energy transfer. At this split-second, clubface angle, swing path, and body alignment converge, revealing how effectively motion, balance, and sequencing were built throughout the swing. Within the BioSwing Dynamics model, three core types—Upper, Middle, and Lower—display distinct biomechanical patterns that shape their P7 mechanics and impact signatures.

    Upper Core Golfer – Steep, Vertical, Controlled by Lead Side

    Upper Core players rely on upper-body dominance and vertical force. At impact, their lead side extends powerfully while the chest rotates through the strike. The hands are ahead of the ball, producing forward shaft lean and a steep, descending blow. The spine remains relatively upright, supporting a cover-style impact. Weight shifts firmly onto the lead leg, and vertical pressure from the lead foot stabilizes the motion. The result: a high-compression, steep strike with a downward angle of attack. Coaches emphasize maintaining lead-side control, upright posture, and timing the trail arm extension without over-releasing.

    Middle Core Golfer – Balanced, On-Plane, Textbook Impact

    Middle Core players achieve neutral positioning and the most “model” impact in golf. They blend vertical and rotational elements, producing a square, repeatable strike. The hands are only slightly ahead of the ball, creating moderate shaft lean with a shallow-to-neutral angle of attack. The pelvis leads the movement, transferring energy efficiently through the kinetic chain. The chest points slightly ahead of the ball, and both arms stay connected to the torso for a stable release. Coaches focus on maintaining spine angle, promoting consistent rotation, and ensuring efficient sequencing for reliable contact and trajectory control.

    Lower Core Golfer – Rotational, Ground-Driven, Shallow Path

    Lower Core golfers use the ground aggressively to generate power. Their impact is rotational and shallow, driven by strong hip clearance and deep spine tilt. The upper body stays behind the ball longer, while the chest remains closed through impact and opens just after. Hands are often even with or slightly behind the lead thigh, supporting a draw-biased strike. Weight pressure moves deeply into the lead leg as vertical ground reaction forces peak at or just after impact. Coaches refine hip timing, encourage shallow delivery, and use ground-up sequencing to enhance dynamic control.

    Coaching Significance – Matching Mechanics to Core Type

    Recognizing how core structure dictates P7 mechanics allows coaches to tailor instruction, reduce compensations, and optimize natural movement patterns.

    • Upper Core Strategy: Train vertical delivery, forward shaft lean, and lead-leg stability for high compression.
    • Middle Core Strategy: Blend rotation and vertical motion for a square, neutral strike with consistent energy flow.
    • Lower Core Strategy: Harness rotational speed and ground force, maintaining spine tilt and timing the trail-arm release for powerful, shallow impact.

    Summary

    P7 is the truth moment of the golf swing—the collision point where preparation becomes performance. Each core type achieves it differently: Upper Core through vertical control and compression, Middle Core through balance and precision, and Lower Core through ground-driven rotation. Understanding these impact dynamics enables coaches to align instruction with natural biomechanics—unlocking each player’s most efficient, repeatable, and powerful strike.

  • #381 Golf Swing P6 – The Delivery Position by Core Type
    2025/10/19

    The P6 position—known as the Delivery Position or Launch Zone—marks the instant just before impact when the club shaft is parallel to the ground. It’s the final checkpoint for sequencing, lag retention, and club path. From here, there’s no turning back—everything is committed to impact acceleration.

    General Function of P6

    P6 reveals whether the downswing has been sequenced efficiently. The lower body should have cleared, the torso rotated, and the hands should lead the clubhead into the hitting zone. It is the moment where stored energy is transferred into the ball. If earlier fundamentals were missed, they become visible here—there’s no time for correction.

    Core-Type Influence (BioSwing Dynamics Model)

    The biomechanics of P6 differ dramatically across the three BioSwing Dynamics core types—Upper, Middle, and Lower Core golfers. Each uses distinct kinetic patterns to deliver the club.

    Upper Core – Upright and Compressive

    Upper Core golfers remain tall, using shoulder rotation and vertical pressure to strike down on the ball.

    • Club & Path: Shaft is steep; hands are higher and in front of the chest, producing a descending blow.
    • Torso & Spine: Shoulders stay open; chest rotates toward the target; spine angle slightly upright.
    • Trail Arm: Right elbow moves in front of the trail hip and begins extending downward.
    • Lower Body: Lead hip clears while pelvis stays centered; force driven vertically through the lead leg.
    • Summary: A steep, powerful delivery driven by torso rotation and vertical compression.

    Middle Core – Neutral and Balanced

    Middle Core players display textbook mechanics: an on-plane downswing with full-body coordination.

    • Club & Path: Shaft perfectly parallel and on-plane; hands slightly in front of the trail thigh.
    • Torso & Spine: Posture consistent; shoulders beginning to open; pelvis leads torso rotation.
    • Trail Arm: Elbow remains close to the rib cage; wrists stay passive, preventing early release.
    • Lower Body: Weight shifts firmly onto the lead foot as hips clear dynamically.
    • Summary: Balanced, repeatable, and efficient—this is the model of a “textbook” P6.

    Lower Core – Shallow and Grounded

    Lower Core golfers deliver from deep inside, powered by aggressive lower-body motion and strong ground interaction.

    • Club & Path: Shaft shallowed under the shoulder plane; hands deeper and behind the trail thigh, promoting an in-to-out strike.
    • Torso & Spine: Chest points right of target; torso remains closed to preserve coil and spine tilt.
    • Lag & Release: Lag retained longest—clubhead trails hands deeply into the delivery zone.
    • Lower Body: Pelvis leads powerfully; lead hip rotates open; knees flexed with firm ground pressure.
    • Summary: Shallow, rotational, and explosive—impact powered by kinetic flow from the ground up.

    P6 as the Final Checkpoint

    At P6, acceleration begins—this is the point of no return.

    • Path & Face Control: Confirms whether the club approaches from a consistent line and face angle.
    • Lag Retention: Ensures the wrists maintain stored energy before release.
    • Body Rotation: Validates proper sequencing—arms leading, hips clearing.

    Key Comparisons

    • Upper Core: Steep and vertical; release beginning.
    • Middle Core: On-plane, controlled; partial lag release.
    • Lower Core: Shallow, inside path; lag preserved longest.

    Summary Insight

    P6 defines how energy will be delivered into impact. Upper Core players compress vertically, Middle Core golfers stay neutral and synchronized, and Lower Core players rotate from the ground up. In every case, P6 represents the ultimate test of efficiency—the last frame before impact where mechanics, rhythm, and power merge into one committed motion.

  • #380 Golf Swing P5: Transition Dynamics by Core Type
    2025/10/18

    P5 marks the transition from backswing to downswing—the instant where stored energy begins its release. At this moment, the lead arm becomes parallel to the ground, and sequencing, rotation, and ground forces accelerate toward impact. According to the BioSwing Dynamics model, how a player transitions through P5 depends on their dominant core type: Upper, Middle, or Lower Core. Each uses distinct biomechanics to initiate motion, influence shaft angle, and control club delivery.

    Upper Core Golfer – Vertical Motion

    Kinematic Sequence:

    Upper Core players initiate the downswing from the upper spine and shoulders, creating a strong lead-side pull pattern. The pelvis remains relatively quiet early, allowing the upper body to dominate before the hips engage.

    Club Delivery:

    This produces a steeper, more vertical path with minimal shaft shallowing. The club stays upright near the shoulder plane, favoring a “cover-style” move into the ball for strong compression. The trail elbow drives downward, preserving lag and guiding a descending angle of attack.

    Middle Core Golfer – Balanced Motion

    Kinematic Sequence:

    Middle Core players display harmonic sequencing between upper and lower body. The hips initiate the downswing through rotation and pressure shift as weight transfers into the lead foot.

    Club Delivery:

    The shaft shallows slightly below the shoulder plane, promoting a square, neutral path. The trail elbow tucks neatly in front of the trail hip, preserving compact lag and supporting efficient, repeatable impact geometry.

    Lower Core Golfer – Ground-Up Motion

    Kinematic Sequence:

    Lower Core golfers transition from the ground up, leading with powerful hip rotation and dynamic weight shift into the lead leg. The pelvis drives the sequence while the upper body remains stable and coiled.

    Club Delivery:

    Their path is rotational and shallow, with the club dropping well below the shoulder plane. This aggressive shallowing generates major lag and sets up a strong inside-out attack. The clubface is slightly closed or neutral, aligning with the rotational geometry.

    Key Swing Geometry at P5

    Arm and Club Path:

    • Upper Core: Lead arm slightly ahead of the chest; upright shaft near shoulder plane.
    • Middle Core: Arm in line with chest; shaft just below shoulder plane.
    • Lower Core: Arm deeper behind the chest; shaft drops noticeably shallower.

    Torso and Initiation:

    • Upper Core: Transition led by shoulders—vertical and pull-driven.
    • Middle Core: Balanced torso rotation maintaining posture.
    • Lower Core: Lower body initiates early; chest remains over trail side.

    Trail Arm & Lag:

    • Upper Core: Downward elbow drive, preserved hinge.
    • Middle Core: Compact elbow tuck, efficient lag retention.
    • Lower Core: Tight elbow-hip connection, extreme lag for stored power.

    Lower Body Action:

    • Upper Core: Late hip rotation; quiet pelvis.
    • Middle Core: Gradual rotation, weight into lead foot.
    • Lower Core: Explosive hip rotation; lead-side pressure spike.

  • #379 Golf Swing P4: The Top of the Backswing – by Core Type
    2025/10/17

    P4 marks the Top of the Backswing, the critical moment when the swing reaches full coil and potential energy peaks before transition. It is the culmination of all preceding movements—how efficiently this position is achieved determines how powerfully and consistently the downswing will unfold. According to the BioSwing Dynamics model, each golfer’s P4 position is shaped by their dominant core region—Upper, Middle, or Lower—defining how energy is stored and released.


    🔹 Upper Core Golfer – Tall, Wide, Powerful

    Upper Core players generate energy from the shoulders and upper spine. Their motion is more vertical, producing a wide, lifted arc and a steep delivery into impact.

    Key Traits:

    • Arm & Club: Lead arm above shoulder height; hands high and away from the body. The club points slightly across the line or toward the target.
    • Rotation: Shoulders coil past 90°, spine tilted away from target for maximum torque.
    • Trail Arm: Elevated and behind the torso, supporting a tall structure and top-down transition.
    • Wrist Set: Strong diagonal hinge; shaft more vertical.
    • Lower Body: Stable hips, weight centered or slightly into trail heel, resisting sway for X-Factor separation.

    🔸 Middle Core Golfer – Balanced, Connected, Efficient

    Middle Core players move with symmetry and stability. Their P4 is compact and centered, promoting neutral rotation and efficient energy transfer.

    Key Traits:

    • Arm & Club: Lead arm roughly at shoulder level, hands close to the body; club on-plane or slightly laid off.
    • Rotation: Shoulders around 90°, hips 40–45°, preserving posture.
    • Trail Arm: Folded and connected to the ribcage, maintaining one-piece structure.
    • Wrist Set: Horizontal hinge to 90°; club set square.
    • Lower Body: Weight fully loaded into trail hip and heel, knees flexed and balanced for seamless transition.

    🔻 Lower Core Golfer – Compact, Deep, Ground-Driven

    Lower Core players harness ground force and rotational leverage. Their P4 is compact, deep, and coiled around the trail side, preparing for a shallower, more efficient delivery.

    Key Traits:

    • Arm & Club: Lead arm below shoulder plane, angled across chest; hands deeper behind body. Club shaft flatter or laid off.
    • Rotation: Chest centered over trail thigh, spine stable, no excess lean.
    • Trail Arm: Tucked close to the body, elbow behind rib cage, supporting shallow path.
    • Wrist Set: Strong vertical hinge for a compact look.
    • Lower Body: Hips deeply rotated; weight into trail glute and heel—ready for ground-up force release.

    💡 Why It Matters

    Each core type’s P4 defines the quality of the downswing:

    • Upper Core: Steep, compressive launch driven from above.
    • Middle Core: Neutral, rotary motion through impact.
    • Lower Core: Shallow, ground-powered strike.

    P4 is not just a static checkpoint—it’s the body’s “loaded spring.” Mastering your core-specific top position ensures that from here, at P5 (transition), energy can flow naturally and explosively toward impact.

  • #378 The P3 Mid-Backswing Position Explained – by Core Type
    2025/10/16

    The Mid-Backswing Position, known as P3, occurs when the lead arm is parallel to the ground and the club begins to hinge. It marks the moment when energy is stored, sequence and swing plane emerge, and the player’s biomechanical DNA becomes visible. Within the BioSwing Dynamics framework, golfers are categorized as Upper Core, Middle Core, or Lower Core—each showing distinct movement patterns and hinge types that define the efficiency of the swing’s transition.

    Upper Core Golfers

    These players move more vertically, relying on arms and shoulders as dominant levers. Their P3 is defined by elevation: the hands are higher and farther from the body, the club shaft sits upright above the shoulder plane, and the wrists create a diagonal hinge. The shoulders rotate strongly while the lower body stays quiet, storing energy through upper-body coil. This structure promotes height and a top-down delivery into the downswing.

    Middle Core Golfers

    Middle Core players show balance and connection between torso and arms. Their motion favors a neutral plane and a horizontal hinge. At P3, the lead arm aligns with the mid-chest, hands remain close to the body, and the club shaft runs parallel to or slightly above the shoulder line. Shoulder and hip rotation stay synchronized, creating an early X-Factor without tension. The lower body turns slightly, loading pressure into the trail glute and heel. This compact structure ensures a fluid transition and consistent plane control.

    Lower Core Golfers

    Lower Core players use the ground early, coiling energy through hips and lower spine. Their P3 appears deeper and more rotational, with the lead arm traveling behind the torso and the hands moving around rather than upward. The club sets flatter and more horizontal, often below the shoulder line, supported by a vertical hinge. The hips rotate early, weight loads into the trail heel, and energy is stored from the ground up—ideal for a shallower, rotary transition and strong impact dynamics.

    Wrist Hinges by Core Type

    Each core type hinges differently: Upper Core golfers employ a diagonal hinge, Middle Core golfers hinge horizontally, and Lower Core golfers hinge vertically. These hinge styles match the player’s natural motion—steep for elevation, neutral for balance, and flat for rotation.

    Lower Body Action at P3

    The lower body mirrors the player’s core type. Upper Core golfers maintain stability with minimal hip movement; Middle Core golfers rotate slightly with centered pressure; Lower Core golfers rotate deeply into the trail hip. These variations define how energy transfers through impact.

    What P3 Reveals

    P3 is a diagnostic checkpoint. It reveals whether a golfer’s motion is vertical, neutral, or grounded; whether power builds through shoulder coil or from the ground up; and how effectively sequencing and hinge patterns match their biomechanical profile. For coaches, identifying a player’s P3 type unlocks the blueprint for efficient energy transfer and repeatable ball-striking.

  • #377 Golf Swing P2: The Takeaway Position by Core Type
    2025/10/15

    The P2 position—where the club shaft reaches parallel to the ground—marks the first dynamic moment of the golf swing. It bridges static setup (P1) and athletic motion, establishing the swing plane, rotation sequence, and energy storage that define power and consistency.

    Why P2 Matters

    At P2, the golfer sets key fundamentals: how the club moves on plane, how the body coils, and how pressure begins to shift. A technically sound takeaway avoids compensations later in the swing and builds the foundation for efficient energy transfer.

    Core Type Influence

    Each golfer’s natural biomechanical “core type”—Upper, Middle, or Lower—shapes how the takeaway unfolds.

    • Upper Core players move top-down. At P2, the club is slightly outside the hands, the shoulders rotate early, and the hands lift quickly, creating a steeper plane. Pressure stays centered or lightly in the trail heel.
    • Middle Core golfers seek symmetry. The club stays on or just inside the hands; the torso and arms move as one while the hips begin turning. Pressure shifts subtly inside the trail foot, keeping balance and rhythm.
    • Lower Core players initiate motion from the ground up. Their club travels deeper and flatter, with the shaft slightly behind the hands. The hips start the move, the shoulders stay quiet, and pressure shifts early to the trail heel—loading for explosive power.

    The Power of P2

    P2 initiates the coil between upper and lower body known as the X-Factor Stretch—a key to speed and control. As the chest and hips begin to rotate, separation builds: PGA Tour data shows roughly –38° chest turn and –22° pelvis turn; LPGA averages –41° and –24°. This early differential stores energy for release through impact.

    Key Technical Elements

    • Club Path: The club moves along or just under the original shaft plane. Too far inside or outside creates later compensations.
    • Body Rotation: The chest and hips rotate together, initiating the X-Factor stretch.
    • Arms & Wrists: The lead arm remains extended, trail arm softly folds, and wrists stay passive—avoiding premature hinging.
    • Pressure & Posture: Light shift toward the trail foot without sway. Maintain spine angle and knee flex.
    • Clubface Check: The leading edge should match spine angle; too open or closed invites timing issues.

    Core Type Variations at P2

    Each core type expresses the takeaway (P2) differently, influencing both club path and body motion:

    • Upper Core – The shaft moves slightly outside the hands, creating a steeper swing plane. The shoulders rotate early with minimal hip motion, and the hands lift quickly.

    • Middle Core – The shaft stays on or just inside the hands, maintaining a neutral plane. Rotation is balanced, keeping torso and arms connected throughout the move.

    • Lower Core – The shaft moves behind the hands, producing a flatter plane. Motion is hip-led, with a deep hand path and passive shoulder action early in the backswing.

    Conclusion

    Mastering P2 means mastering your motion’s DNA. It’s not just a checkpoint—it’s the start of rhythm, power, and sequence. Understanding how your core type drives the takeaway transforms P2 from a simple movement into the engine of your entire swing.

  • #376 Golf Swing P1: Address Position by Core Type
    2025/10/14

    The address position—P1—is where every great swing begins. It’s the static foundation from which motion, balance, and power emerge. A correct P1 ensures the body and club are synced before the backswing starts. Within the BioSwing Dynamics model, golfers are classified as Upper Core, Middle Core, or Lower Core players—each requiring a distinct setup to match natural biomechanics.

    Upper Core Golfer – Vertical Motion

    Upper Core players move more from the upper spine and shoulders. Their motion is upright and rotary, producing a steeper plane. They stand taller at address, with limited hip hinge and a chest that stays high. Hands are set higher—often in line with the shoulders—and the trail arm sits “on top” of the shaft. The club rests more upright, the ball slightly forward, and the stance is narrower with light knee flex. Balance often favors the balls of the feet, promoting freedom for an easy shoulder turn and vertical release.

    Middle Core Golfer – Neutral Motion

    The Middle Core player represents biomechanical balance. Motion starts from the body’s center, with the trail arm moving level to the torso. At P1, posture shows a moderate hip tilt and neutral spine, the right shoulder slightly lower. Hands rest near shoulder height, arms soft beside the ribcage. The grip and shaft lean are neutral, with the ball centered or just ahead. Feet are shoulder-width apart, weight evenly distributed, and knees naturally flexed. This neutral address creates symmetry—ideal for a rotational yet fluid swing.

    Lower Core Golfer – Grounded Motion

    Lower Core players use the ground as their engine. Power comes from hips and legs, creating a flatter, deeper swing plane. Their setup features a stronger hip hinge and more forward bend. The torso tilts closer to horizontal, with hands lower and arms hanging vertically. The trail elbow tucks into the body to support an inside path. The shaft lies flatter, the ball slightly back, and the stance wider with more knee flex. Weight favors the heels, giving a stable base for heavy lower-body engagement and a powerful rotary motion.

    Matching Core and Balance

    There is no single perfect weight distribution—it’s defined by body type. Middle Core golfers balance evenly across the feet, maintaining centered control. Lower Core golfers ground pressure toward the heels, building stability for hip-driven motion. Upper Core golfers, more upright, feel balance toward the balls of the feet to promote an agile pivot.

    Why Core Type Matters

    Small address variations can trigger major swing changes. A deeper hip hinge lowers the hand path and flattens the plane; higher hands lift it and steepen attack. Aligning P1 with one’s dominant core ensures motion efficiency, consistent contact, and natural rhythm.

    In essence, the setup is not “one swing fits all.” It’s an anatomical partnership—posture, stance, and hand height tuned to the golfer’s engine room, whether it lies in the shoulders, the center, or the hips. Perfect P1 means perfect potential.
