Kinematic Breakdown of Roberto De Vicenzo’s Motion for Data-Driven Technique Mastery
Roberto De Vicenzo’s swing shows that a powerful, repeatable motion is created by an ordered chain of movements rather than static positions. From a kinematic perspective, his action follows a sequential ground-up pattern: pressure shifts begin in the feet and legs, the pelvis and ribcage respond next, and finally the arms and club are delivered to the ball. At address, copy his poised, athletic setup by placing roughly 55-60% of your weight on the lead side with irons and closer to even (50-50) with the driver. Keep the knees softly flexed and tilt the spine a touch away from the target-about 5-10° with the driver-to encourage an upward angle of attack. Initiate a “quiet” takeaway: keep the clubhead close to the turf for the frist 30-40 cm as the chest, arms, and hands move together as one unit. This minimizes early wrist set and maintains the club on plane. A helpful drill is to position an alignment stick just outside the ball and rehearse slow-motion backswings that pass inside the stick, developing a neutral swing path. Newer players should prioritize balance and tempo; experienced golfers can track hip rotation of about 35-45° at the top to avoid an over-long backswing that destabilizes structure and timing.
As De Vicenzo changed direction from backswing to downswing, he displayed highly efficient energy transfer: the lower body initiated while the torso and arms briefly resisted, generating measurable separation (the “X-factor”). To apply this pattern, feel pressure in the lead foot rise to 70-80% by impact, with the lead hip rotating toward the target as the chest remains marginally closed for an instant. This sequence promotes an in-to-out path for a draw or a neutral path for straight shots, depending on clubface control.On full swings, picture your belt buckle facing the target at impact, while your head stays relatively steady behind the ball. Common errors include an early upper-body lunge, which encourages slices and fat shots, and hanging back on the trail side, which tends to produce thin strikes and hooks.Address these with targeted drills such as:
- Step-through drill: Begin with your feet together, swing back, then step toward the target with the lead foot as the downswing begins to train forward pressure and dynamic balance.
- Impact checkpoint drill: Freeze in a rehearsal impact position with hands slightly ahead of the ball on iron shots, weight predominantly on the lead leg, and the shaft leaning forward about 5-10°. Then swing through. This reinforces ball-first contact and proper compression.
- Half-swing tempo drill: Make waist-high to waist-high swings concentrating on smooth acceleration through the ball, echoing De Vicenzo’s calm yet decisive rhythm to improve distance control and shot dispersion.
De Vicenzo’s ability to score was equally anchored in precise short game mechanics and thoughtful course strategy. Around the green, his chipping stroke was compact, with limited wrist action and the torso driving the motion-an ideal pattern for consistent contact from a variety of lies. for standard chips,set 60-70% of your weight on the lead foot,position the ball slightly back of center,and keep the clubface modestly open so the bounce,not the leading edge,engages the turf,especially on tight lies.Strategically, follow his evidence-based mindset: pick targets that support your normal shot shape, favor the safer side of the green when hazards pinch the flag, and adjust for conditions such as downwind, firm fairways (consider more loft or less club) and into-the-wind approaches (take extra club and swing at 80-85% effort to moderate spin and curvature). Build this into training by alternating technical range sessions with “simulated rounds,” where you select specific fairway and green targets and track fairways hit, greens in regulation, and up-and-down percentage. This mirrors De Vicenzo’s fusion of sound mechanics with disciplined decision-making and provides golfers at all levels with a measurable pathway to lower scores and more composed play under competitive pressure.
Biomechanical Adjustments to Resolve Common Swing Faults Through De Vicenzo-Inspired Movement Patterns
Expanding on Roberto De vicenzo’s fluid, athletic action, biomechanical solutions for typical swing issues begin with posture, balance, and pivot quality.Many golfers address the ball either too upright or excessively rounded,altering spine tilt and limiting rotation. Aim for a neutral setup with 25-35° of forward bend from the hips,knees softly flexed (without squatting),and weight distributed 55-60% toward the balls of the feet. This promotes a stable axis so the shoulders can turn without excessive lateral sway. de Vicenzo’s swing showcased a centered pivot: his head stayed relatively steady while the trail hip turned away from the target. To mirror this, imagine your trail hip moving back and slightly up instead of sliding side to side. A practical checkpoint is ensuring that at the top of the backswing your trail hip remains at least 2-3 cm away from where it started relative to a reference line (alignment stick, bag stand, or similar). This adjustment decreases the likelihood of a “reverse pivot” and reduces the tendency to come “over the top,” setting the groundwork for a shallower, more forceful downswing.
From this stable pivot, De Vicenzo’s movement patterns can be applied to tackle casting, early extension, and loss of lag. His transition contained a subtle sequencing advantage: the lower body initiated the downswing while the arms and club retained angle, preserving lag. To replicate this, sense a gentle pressure shift into the lead foot just before the backswing completes. Aim for a lead-foot pressure increase of roughly 10-15% as the backswing finishes-a feel that can be trained without specialized equipment. This helps shallow the club and counters an over-the-top move.For golfers who thrust their hips toward the ball (early extension), prioritize maintaining hip depth by feeling your glutes remain in light contact with a chair, bag, or imagined wall throughout the motion. This encourages correct pelvic rotation instead of crowding the ball. On the practice tee, incorporate these De Vicenzo-inspired drills built around rhythm and connected motion:
- Trail-hand-only half swings: Hit gentle shots using only the trail hand, focusing on keeping a 90-100° shaft angle in the downswing until your hands reach about hip height.
- Chair-or-wall hip depth drill: Address the ball with your glutes just touching a chair or wall and rehearse slow swings that keep that contact through impact, training rotation without moving closer to the ball.
- Step-through drill: Begin with feet together, then step into the lead side as you start down, simulating De Vicenzo’s athletic weight shift and developing effective ground reaction forces.
These biomechanical enhancements must ultimately show up in shot patterns, scoring, and adaptable course tactics. On the course, De Vicenzo’s stable, repeatable motion enabled him to curve shots on demand without abandoning his base mechanics. After stabilizing pivot and sequencing on the range, deliberately test them in diffrent environments: into a strong breeze, maintain 70-80% effort while shortening the arm swing to a three-quarter length but preserving body rotation; in wet or muddy conditions, exaggerate lower-body stability and minimize lateral sway to protect impact quality. For higher handicaps, the main objective is shrinking catastrophic misses: record fairways hit, greens in regulation, and fat/thin strikes over consecutive nine-hole segments before and after introducing these changes. For low handicaps, refine dispersion by practicing with planned shot shapes while retaining De Vicenzo-style fundamentals:
- Three-ball pattern drill: On the range, hit a fade, straight shot, and draw in sequence using the same posture and pivot, altering only clubface aim and ball position. This reinforces that path and contact are rooted in solid biomechanics rather than last-second hand manipulation.
- On-course benchmark test: Select a par 4 and play it three times with distinct focal points: first round-balanced posture and centered pivot; second-weight shift and hip depth; third-tempo and rhythm. Record scores and shot dispersion to directly link swing priorities to outcomes.
- Mental rehearsal routine: Before each shot, picture De Vicenzo’s smooth transition and repeat a simple cue such as “turn, shift, through” to blend the pattern into your swing under pressure.
By marrying these classic movement signatures with modern biomechanical checkpoints, golfers at any skill level can correct faults in a structured, measurable way, leading to more consistent ball striking, sharper strategic thinking, and lower scoring averages.
Applying focused Skill-Acquisition Drills to Internalize De Vicenzo’s swing Principles
To convert De Vicenzo’s timeless, efficient swing into a personal, repeatable pattern, golfers should start with blocked technical drills that isolate essential movement qualities: stable posture, even tempo, and a square clubface at impact.At setup, rehearse a neutral grip with the lead thumb positioned around 1 o’clock on the grip (for right-handed players), combined with a spine tilt of roughly 10-15° away from the target with irons and 15-20° with the driver. Lay an alignment stick on the ground to verify that your feet, hips, and shoulders run parallel to the target line. then introduce a slow-motion mirror drill: swing at 25-30% speed, pausing at key checkpoints-club parallel to the ground in the takeaway (shaft matching the target line), lead arm positioned across the shoulder line at the top, and in the downswing, hands slightly ahead of the clubhead at impact with about 70% pressure on the lead side. This helps beginners build basic coordination and gives advanced players a precise way to refine shaft lean, clubface orientation, and sequencing without the variability of full speed.
Once these foundational positions feel reliable, the next phase is to add variability and playing realism so that De Vicenzo’s concepts remain intact under stress and diverse course conditions. to encourage his hallmark smooth rhythm, use a metronome or counting pattern (such as, “one” to the top, “two” to impact) and hold that cadence while hitting shots from different lies and tee heights. Structure practice into compact, purposeful blocks such as:
- Rhythm and contact ladder: Hit 5 balls at 50% speed, 5 at 70%, and 5 at 80%, keeping the same count in your head. Monitor center-face contact with impact tape or foot spray; aim for at least 10 of 15 solid strikes before increasing difficulty.
- Trajectory control drill: With a mid-iron, alternate high and low shots by moving the ball within a 6-8 cm window in your stance and making only minor changes to shaft lean. This teaches the relationship among setup, path, and launch-skills De Vicenzo routinely leveraged to handle wind and firm greens.
- Balance and finish check: Hold your finish position for a full 3 seconds after every swing. If you cannot hold it, reduce effort until you can. A held finish is a strong indicator of proper weight transfer and controlled clubhead speed.
These tasks help all golfers connect feel to measurable output-launch window, strike quality, and dispersion-so the motion becomes robust instead of fragile.
To fully embed these ideas into scoring performance, skill acquisition must also cover the short game and on-course decision-making, where De Vicenzo’s strategic discipline was especially clear. Around the greens, employ a “one-setup, three-club” routine: keep ball position slightly forward of center, stance just narrower than shoulder width, and weight tilted about 60-65% toward the lead foot, then rotate through a pitching wedge, gap wedge, and sand wedge. Maintain a slightly open clubface,a relaxed grip,and match backswing length to desired carry distance. This gives beginners contact consistency and provides better players with predictable roll-out profiles for each club. On the range, simulate complete holes by selecting a virtual fairway (about 25-30 yards wide) and playing “imaginary rounds”:
- Tee shot: Choose a conservative target line that leaves your usual miss on the safe side-mirroring De Vicenzo’s approach under pressure-and assess whether the ball woudl finish in the fairway.
- Approach shot: Aim for the largest safe section of the green with a club you can carry at least 5-7 yards past the front hazard under normal wind, valuing greens in regulation over attacking tucked pins.
- Mental routine: Before every shot,follow a fixed sequence: evaluate lie and wind,pick a precise landing spot,rehearse a single swing feel (e.g.,”smooth tempo” or ”solid left side”),then execute with no new swing thoughts once you start back.
By blending these structured drills with clear, data-driven goals-such as boosting fairways hit by 5-10% or reducing the number of holes requiring multiple chips-the player develops a swing-and-strategy package that, like de Vicenzo’s, remains reliable in changing weather, under tournament stress, and on a variety of course designs.
Converting De Vicenzo’s Swing Model into Strategic Course Management and Performance Gains
De Vicenzo’s swing framework-built on a balanced pivot, delayed hand release, and steady rhythm-naturally supports smarter course management when players connect specific shot patterns to conservative, high-percentage targets. For example, his slightly closed upper-body alignment and intentional right-to-left ball flight (a controlled draw) are best used to challenge left-hand pins only when there is ample room long and right, with the clubface aimed near the green’s center to preserve a margin for error. Golfers should first determine their own reliable shot shape-whether it is indeed a gentle fade, stock draw, or straight ball-and then choose lines off the tee and into greens that push the “big miss” toward the safe side of the hole.A practical mechanical checkpoint is maintaining 55-60% of your weight on the lead foot at impact with irons to ensure ball-first contact and a predictable trajectory. Once contact is consistent, course strategy becomes the art of choosing the highest-percentage shot, not necessarily the boldest one, while accounting for wind direction, turf firmness, and the location of penalty areas.
To embed De Vicenzo’s consistent motion into real-world performance, golfers should adopt structured pre-shot routines and shot-specific rehearsals that combine technical cues with target choices. on approach shots, rehearse a three-quarter tempo swing where the lead arm stops around 10 o’clock on the backswing for more precise distance control, then select a club that travels 5-10 yards beyond the required carry to allow for slight mishits-a conservative yardage practice common among elite players. Around the green, his preference for simple, putting-like chipping actions can guide both club selection and landing-zone strategy. Faced with a basic chip, many golfers can default to a pitching wedge or 9-iron, stand with a narrow stance (no wider than shoulders), place the ball a bit back of center, and minimize wrist hinge while focusing on a landing spot 1-2 yards onto the putting surface. To reinforce this, build a short-game practice menu that includes:
- Landing-spot ladder drill: Place tees or coins at 1, 2, and 3 yards onto the green and hit 10 balls to each zone, counting how many finish inside one club-length of the target.
- Trajectory comparison drill: Use the same landing zone but alternate between sand wedge, gap wedge, and 9-iron to observe different roll-out patterns and determine which option is most reliable for you.
- pressure routine drill: Before every chip, run through your full process-visualization, practice stroke, and alignment-so that technique becomes linked with a calm, repeatable decision-making routine.
Optimizing performance in De Vicenzo’s style also requires a intentional integration of equipment choices, practice design, and mental planning. Off the tee, players should fit themselves into a driver and shaft combination that delivers a launch angle of roughly 11-14° and spin rates in the 2200-2800 rpm range for typical male swing speeds, a window that modern launch-monitor data associates with both strong carry and controllable dispersion. De Vicenzo’s compact, repeatable driver swing can be emulated by prioritizing center-face contact over raw speed; practice this by hitting 5-ball blocks where the goal is to land every shot within a 20-yard-wide corridor, modifying aim and club selection as if you were playing different holes. To manage common scoring killers-such as early extension, racing the putterhead through impact, or attempting miracle recovery shots-adopt on-course guidelines like:
- Recovery commitment rule: Whenever you find yourself in serious trouble (trees, deep rough, high-lip bunkers), commit to a “back-to-the-fairway-in-one” policy rather of going directly at the green.
- Two-putt priority: From outside 25 feet, read putts with the primary objective of leaving the ball within 3 feet of the hole. Routine two-putts reduce score volatility far more than the occasional long make improves it.
- Wind and lie adjustments: Into a strong headwind,take at least one extra club and swing at 80-85% effort to maintain balance and control spin; from downhill lies,anticipate a lower launch and extra roll-out,and aim for the broadest,safest portion of the green.
By merging De Vicenzo-inspired swing simplicity with conservative target selection and quantifiable practice objectives, golfers at every level can translate technical improvements into tangible scoring gains and more consistent performance in both tournament and recreational play.
Steal Roberto De vicenzo’s Legendary Swing: Simple Moves to Master, Fix & Transform Your Game
Why Roberto De Vicenzo’s Swing Still Works in Modern Golf
Roberto De Vicenzo was famous for an efficient, repeating golf swing that held up under pressure on the PGA Tour and across decades of competitive play. You don’t need his athleticism or versatility to borrow the core golf swing fundamentals that made him so consistent. His motion was:
- Simple and compact – no wasted movements
- Rhythmic – a smooth tempo from takeaway to finish
- Balanced – excellent posture and weight transfer
- Target focused – a clear picture of the shot before he swung
By reverse engineering those traits into modern golf swing drills, you can improve ball‑striking, fix slices and hooks, and build a golf game that holds up under pressure.
Core Building Blocks of the De Vicenzo‑Style Swing
1. Solid Golf Setup: posture, Grip, and Alignment
Before the club moves, De Vicenzo’s position over the ball did most of the work. Copy these simple keys.
Posture Checklist
- Feet: About shoulder‑width for irons, slightly wider for the driver.
- Knees: Soft,not squatting; feel springy,as if ready to jump.
- Hip hinge: Bend from the hips, not the waist-straight back, chest proud.
- Arms: Hang naturally from your shoulders; avoid reaching or crowding the ball.
- Weight: Centered over the balls of your feet, not on your heels.
Neutral Golf Grip
- Lead hand (left for right‑handed golfers): See 2-3 knuckles; logo between right ear and right shoulder.
- Trail hand: Palm facing the target; “V” between thumb and index finger pointing toward your trail shoulder.
- Pressure: 4-5 out of 10 – secure but relaxed to allow clubhead speed.
Alignment Made Easy
- Pick a small spot about 2 feet in front of the ball directly on your target line.
- align the clubface to that spot first.
- Then align your feet, knees, hips, and shoulders parallel to the target line (like railroad tracks).
2. Smooth Takeaway and One‑Piece Move
De Vicenzo’s takeaway was unhurried and connected.That’s crucial for consistent golf ball contact.
- start the club back with your chest and shoulders,not your hands.
- The clubhead stays outside your hands in the first 12-18 inches.
- Keep the club low to the ground for the first part of the backswing.
- Maintain your triangle (shoulders and arms) for as long as possible.
Feeling: As if the club, hands, arms, and chest are moving together for the first third of the swing.
3. Compact Backswing With Full Shoulder Turn
Roberto’s swing never looked long or loose, but he still generated power thru coil.
- Shoulders: Turn until your back faces the target (or as close as your mobility allows).
- Hips: Allow some rotation (30-45°) so you don’t strain your lower back.
- Lead arm: Relatively straight but not locked-maintain structure.
- Wrists: Set the club so it forms about a 90° angle with your lead arm at the top.
- Club position: Short of parallel is fine; prioritize balance and control over length.
4. Simple Downswing: Lead With the Lower Body
De Vicenzo’s power came from a well‑sequenced golf downswing, not brute strength.
- Shift pressure into your lead foot to start the transition.
- Unwind your hips toward the target-chest follows,then arms,then clubhead.
- Keep your back to the target for a split second as the lower body starts, creating lag.
- Maintain posture-no early standing up; feel your chest staying over the ball.
- Let the club release naturally through impact; avoid forcing a flip with your hands.
5.Balanced Finish for consistency
De Vicenzo’s finish position was classic: fully rotated, tall, and balanced.
- Chest facing or slightly left of the target (for right‑handed golfers).
- Trail foot up on the toe, heel off the ground.
- Weight 90%+ on the lead side.
- Club wrapped around your body, hands near your lead shoulder.
Check: You should be able to hold your finish for three seconds without wobbling.
Key Golf Swing moves to Copy from De Vicenzo
| Move | what to copy | Benefit |
|---|---|---|
| Pre‑shot routine | Same steps every swing | Confidence & rhythm |
| Tempo | Slow, unhurried takeaway | Better timing |
| Compact top | Short of parallel | More control |
| Lower‑body lead | Hips start downswing | Added power |
| Balanced finish | Hold for 3 seconds | Consistent contact |
Drills to Master a De Vicenzo‑Style Golf Swing
1.Towel Under Arms Drill (Connection)
Goal: Build a one‑piece takeaway and compact, connected swing.
- Place a small towel or headcover under both armpits.
- Hit half‑swings with a short iron, keeping the towel in place.
- Focus on chest‑driven motion and soft hands.
Coaching cue: If the towel drops early, your getting handsy or disconnecting from your body.
2. step‑Through Drill (Weight Transfer)
Goal: Learn to shift pressure to your lead side like De Vicenzo without swaying.
- Address the ball normally with a mid‑iron.
- make a backswing with a slightly narrower stance.
- As you start the downswing, step your trail foot toward the target and swing through.
This exaggerates moving into your lead side and can quickly fix a reverse‑pivot or hanging back.
3. 3‑second Finish Drill (Balance & Control)
Goal: Train a reliable,balanced finish.
- On the driving range,hit 10 balls with any club.
- After each swing, hold your finish for three seconds.
- Score yourself: 1 point for each swing you can hold easily.
A score of 8/10 or better shows you’re controlling the golf club and your body like a tour player.
4. 9‑to‑3 Drill (Impact Focus)
Goal: Emphasize the most important part of the golf swing: from hip‑high to hip‑high.
- Make “9‑to‑3″ swings-club shaft parallel to the ground in the backswing (9 o’clock) to parallel after impact (3 o’clock).
- Keep your lower body stable but allow a natural pivot.
- Focus on solid contact and forward shaft lean at impact.
This drill is excellent for improving ball‑striking and compressing your irons.
Fixing Common swing Faults Using De Vicenzo’s Principles
1. How to Fix a Slice
De Vicenzo’s slightly inside‑to‑square path and full rotation are ideal antidotes to the typical amateur slice.
- Check grip: Rotate the lead hand slightly to see 2-3 knuckles; ensure the trail hand is not overly weak.
- Path focus: Place an alignment stick just outside the ball; swing from inside that stick to the target.
- Body rotation: Feel your chest turning through impact instead of stalling and letting the hands take over.
2. How to Fix a Hook
- Neutralize grip: If you see 4+ knuckles with your lead hand, rotate it slightly toward the target.
- Width in takeaway: Avoid rolling the club too far inside; keep it in front of your chest.
- Tempo: Slower transition at the top; don’t yank the club down with your hands.
3. How to Improve Contact and Ball‑Striking
- Maintain posture: Practice with a chair touching your backside; avoid standing up through impact.
- Pressure shift: At impact, feel 70-80% of your weight on your lead foot.
- Low point control: Brush the turf ahead of the ball when practicing irons.
Tempo and Rhythm: The Secret Sauce of De Vicenzo’s Golf Swing
One of the most “stealable” parts of De Vicenzo’s game is his golf swing tempo. A smooth ratio of backswing to downswing-around 3:1-is common among elite players.
Metronome & Count Drill
- On the range, say “one‑two‑three” during your backswing and “hit” as you swing down.
- Alternatively, use a metronome app set around 60-70 bpm for the backswing and feel the downswing naturally quicker.
Consistent rhythm does more for distance and accuracy than forcing speed.
On‑Course Strategy Inspired by De Vicenzo
Roberto De Vicenzo was more than a great ball‑striker; he was a smart course manager. Use his strategic concepts to lower your scores without changing your golf swing overnight.
- Play to your stock shot: If your normal shot is a little fade or draw, aim so that miss ends up in a safe area.
- Centre of the green: Unless you’re inside 130 yards with a wedge, aim at the middle rather than tucked pins.
- Smart club selection: Take the club that removes the biggest trouble (e.g.,bunkers,water) from play.
- Pre‑shot routine: One rehearsal swing, commit to the target, step in, and pull the trigger-every time.
Simple Practice Plan to Transform your Golf Game

|---|---|---|
| Warm‑up | 10 min | Stretch, slow wedges |
| Technique | 20 min | Towel & 9‑to‑3 drills |
| Full swings | 20 min | Balanced finish drill |
| Short game | 20 min | Chipping & putting |
Weekly Structure
- 2 range sessions focused on drills and full‑swing mechanics.
- 1 short‑game session (chipping, pitching, putting) minimum.
- 1-2 rounds were you prioritize tempo and strategy over swing thoughts.
Adapting De Vicenzo’s Swing to Different Skill Levels
For Beginners
- Prioritize grip, posture, and alignment.
- Use half‑swings and the 9‑to‑3 drill to groove contact.
- Pick a simple stock shot shape and stick with it.
For intermediate Golfers (10-25 handicaps)
- Refine weight transfer and hip rotation.
- Track fairways hit and greens in regulation to measure progress.
- Add shot‑shaping practice (baby fade, gentle draw) without overcomplicating.
For Advanced Golfers
- Dial in distance control with wedges using De Vicenzo‑style tempo.
- Use stat tracking apps to identify scoring leaks (e.g., approach vs. putting).
- Practice pressure drills-e.g.,9‑hole challenges on the range,must hit fairway or restart.
Case Study: A Mid‑Handicapper “Steals” De Vicenzo’s Swing
Consider a 16‑handicap golfer struggling with a slice and inconsistent contact. Over eight weeks, he applied de Vicenzo‑inspired principles:
- Weeks 1-2: Rebuilt grip and stance, added towel drill for connection.
- Weeks 3-4: Focused on tempo (3:1 count) and the step‑through drill for weight transfer.
- Weeks 5-6: Integrated a consistent pre‑shot routine and the 3‑second finish drill on every full swing.
- Weeks 7-8: Shifted focus to on‑course strategy-aiming at the fat side of greens and playing a stock fade.
Results: Driving accuracy improved by ~20%, greens in regulation increased by 3-4 per round, and his handicap dropped to 12 without chasing more swing speed-just better mechanics and smarter decisions modeled on De Vicenzo’s game.
Practical Tips to keep the Legendary Swing Working Under Pressure
- One swing thought only: On the course,pick a single cue (e.g., “smooth tempo” or “turn through”) and commit.
- Visualize shots: Before every swing, picture the ball’s flight and landing area.
- Practice from poor lies: De Vicenzo was known for creativity; rehearse punches,knockdowns,and recovery shots.
- Track progress: Keep simple stats-fairways hit, greens hit, and putts per round-to verify improvements.
Apply these simple, classic moves with modern feedback tools-video, launch monitors, and stats-and you’ll effectively “steal” Roberto De Vicenzo’s legendary swing to master, fix, and truly transform your golf game.
