There has never been more free swing instruction in human history, and the average golfer has barely improved in thirty years. Those two facts belong in the same sentence. The internet hands out fixes by the thousand, and fixes are the easy part. It cannot hand out the diagnosis, and a fix applied to the wrong problem makes a swing worse while convincing its owner he is one tip away.
Between the two of us we have taught more than 10,000 lessons, and we can tell you the real difference between how a coach improves a swing and how a golfer tries to improve his own. It is not secret knowledge. It is the order of operations. A coach reads the ball first, then the strike, then the body, because each step narrows the search for the next one. Most golfers run the sequence backward, copying a body position from a video and hoping the ball approves. So instead of another list of tips, this is the full diagnostic chain the way we run it on the lesson tee, written so you can run it on yourself.
The Ball Is Telling You What’s Wrong
Every shot you hit is a report on two things: where your clubface pointed at impact and where your club was traveling. Learn to read that report and half of all swing confusion disappears, because you stop guessing which of fifty possible flaws you have and start working from evidence.
The modern reading goes like this. The ball starts very close to where the face was pointing at the moment of contact, and it curves away from the direction the club was moving. That second part surprises people, because golf instruction taught the opposite for decades until launch monitors settled the argument. It explains why so many old fixes never worked: they were built on a backwards map.
Run your common shots through it. A ball that starts left of your target and bends hard right, the classic slice, means the face pointed left of your path while the path itself cut across the ball to the left. A ball that starts at the target and dives left means the face was square to the target but closed to a path swinging out to the right. A straight push or straight pull with no curve means face and path matched each other; your contact was actually pure and your aim or path simply sent it elsewhere, which is a very different problem from a curve.
Before any practice session, hit ten shots and write down only two things per shot: where it started and which way it curved. That pattern is your diagnosis. A coach charges for the trained eye, but the ball reports to everyone for free.
Check the Strike Before You Change the Swing
The second question a coach answers, and the first thing Thomas looks at, usually within the first five swings of a lesson, is where on the face you make contact. Golfers obsess over swing shape while ignoring strike location, and strike location quietly controls distance, direction, and that harsh feeling in the hands on cold mornings.
The test costs a few dollars. Buy a can of athlete’s foot spray, dust the clubface, and hit five balls. Every strike leaves a mark, and the marks tell their own story. A cluster out on the toe usually means your arms are pulling in through impact or you are standing a touch too far from the ball. Marks crowding the heel often point to your body pushing toward the ball as you swing down, the move that in its worst form produces the shank. Marks low on the face go with thin contact and a low point arriving too early; marks scattered everywhere mean your body’s center is wandering during the swing and no path fix will help until it settles.
Here is why this test comes second in the chain: a centered strike with a crooked path produces a playable, predictable curve. A perfect path with strikes sprayed across the face produces chaos that no alignment, grip, or positional change can rescue. If your spray pattern is scattered, strike is your project, and the practice structure for fixing it lives in our piece on how to get better at golf. If your strikes are centered and the ball still curves too much, keep reading, because your problem is face and path, and that is very fixable.
Why Is My Golf Swing So Inconsistent?
The most common sentence spoken on our lesson tee is some version of “I just want to be consistent,” usually from a golfer convinced his swing has a dozen separate problems. It almost never does. An inconsistent swing is usually one problem wearing several disguises.
It works like a row of dominoes. One early error, very often in the grip, the setup, or the takeaway, forces the body to invent a correction mid swing. That correction creates its own side effect, which demands another correction, and by impact the golfer is performing three rescues in a quarter of a second. On the days his timing is sharp, the rescues land and he shoots 84. On the days it is not, the same swing shoots 95. The swing did not change between Saturday and Sunday. The timing of the rescues did.
This is the heart of how a coach improves a swing. The coach hunts for the first domino and ignores the rest, because the compensations dissolve on their own once the original error is gone. The golfer working alone does the opposite: he sees the last, most visible move on video, polishes that compensation, and wonders why the swing fights back. If you take one idea from this whole page, take this one. Whatever looks ugliest in your swing video is probably a symptom. The cause almost always lives earlier, and very often it lives before the club ever moves.
The Swing Mistakes That Show Up on Every Lesson Tee
After enough thousands of students, the first dominoes sort themselves into a short list. These five account for an enormous share of amateur trouble, and each comes with a check you can run on yourself today.
The Grip That Holds the Face Open
A grip with the lead hand rotated too far toward the target leaves the clubface hanging open through impact, and an open face is the engine of the slice. The check takes ten seconds: look down at your lead hand at address. If you can see fewer than two knuckles, your grip is working against you on every swing. Rotate the hand away from the target until two knuckles, even two and a half, show clearly, and let the trail hand fold over so its palm faces the target. The new hold will feel strange for a couple of weeks. That feeling is the fix taking, not a sign it is wrong.
Aim That Lies to You
Most golfers who fight a curve also aim well away from their target without knowing it, because the body learns to pre-correct for the shot it expects. The two combine into a system that only works when both errors show up on schedule. Build a station: one club on the ground along your toe line, another just outside the ball pointing at the target. The first time slicers do this, they discover they have been aiming a fairway’s width right for years. Straightening the aim feels terrifying for a session and then the pre-corrections start to die off, because they no longer have a job.
Ball Position That Drifted
Ball position migrates the way a part in your hair does, slowly and without permission. An inch too far back steepens the strike and starts shots right; an inch too far forward invites thin contact and a wandering start line. Check it with two clubs laid in a T, one along your toes and one perpendicular to the ball. Short irons belong near the center of your stance, mid irons a ball forward of that, and the driver off the lead heel. Most golfers who run this check find at least one club family has drifted, and correcting it fixes shots they had blamed on their swing.
Swinging at One Hundred Percent
Full effort is the most popular swing flaw in golf because it feels productive. It also moves the strike off the center of the face, and an off-center hit at full speed flies shorter than a centered hit at eighty percent, which means the golfer swinging hard for distance is actively giving distance away. The proof is more persuasive than the lecture: dust the face with spray, hit five at full effort and five at what feels like eighty, and compare both the marks and the carry. Nearly everyone finds their eighty percent swing is their real hundred.
Standing Up Through the Ball
Coaches call it early extension: the hips drift toward the ball on the downswing, the spine rises, and the arms run out of room, producing heel strikes, blocks to the right, and the occasional hook when the hands rescue it at the last instant. Test yourself with a chair. Set up with your backside barely touching the chair back, then make slow swings keeping that light contact into the follow through. If you peel off the chair the moment the downswing starts, you have found your first domino, and slow rehearsals against that chair will do more for you than a season of band-aid tips.
How to Fix Your Golf Swing Without Making It Worse
Diagnosis is half the coaching method. The other half is how a change gets installed, and this is where self-taught fixes usually die, not because the fix was wrong but because the installation broke.
Change one variable at a time, and only one. The swing takes around a second and a half, and a brain juggling three thoughts inside that window executes none of them. Pick the first domino and give it exclusive rights to your attention for at least two weeks.
Exaggerate past the target. A move that has lived in your swing for years will not leave because you nudge it. When students see their video, what they swore felt like a massive change usually shows up as barely visible. To make a real swing change, the new feel should seem almost comical. If it feels reasonable, it probably has not happened yet. Jack calls this gap feel versus real, and it is the single most useful concept in swing changing.
Rehearse slow and without a ball before you rehearse fast with one. Speed hides everything. A movement you cannot perform at quarter speed in the living room does not exist yet at full speed on the course.
Let the ball flight get worse before it gets better, on purpose. A genuine change disrupts the old compensations before the new pattern stabilizes, and the ugly two weeks in the middle is where almost every self-directed swing change gets abandoned. The timelines for how long changes take to hold up are laid out in the getting better article; the short version is that quitting during the dip is the most common way golfers protect their old slice.
Does Video Analysis Help a Golf Swing?
Used correctly, the camera is the closest thing to a coach you can carry in your pocket, because it ends the argument between feel and real. Used the way most golfers use it, it manufactures problems.
Correct use starts with the setup. Film from two angles only: down the line, with the camera at hand height directly behind your hands and pointed along the target line, and face on, at chest height squarely in front of you. Move the camera off those positions and the angles will show you faults you do not have, which is how a golfer ends up fixing imaginary problems for a month.
Then limit what you look for. Three checkpoints cover most of what an amateur can act on: at address, does your setup match the checks in the section above; at the top, has the club stayed roughly on line with your forearm rather than pointing well across; at impact, on the face-on view, are your hips and chest open with your weight clearly on the lead side, or are you hanging back. Anything beyond those three belongs to a trained eye, and frame-by-frame self-surgery at midnight has wrecked more amateur swings than any range ever fixed.
Do Professional Golfers Have Swing Coaches?
Every one of them, and the reason cuts to the center of this whole subject. Impact lasts about half a millisecond. No human being, including the best ball strikers alive, can feel or see what their face and path are doing in a window that small, and feel drifts further from reality every week a player practices alone. The professionals with the most refined feel on earth still pay for outside eyes precisely because they know their own feel cannot be trusted unsupervised.
That is what a coach is actually for, and it has little to do with knowing secrets. A coach sees the face-path relationship you cannot feel, finds the first domino under the visible symptom, holds the record of your tendencies over months so this year’s fix accounts for last year’s, and stops you the day your practice starts grooving a new mistake. A weekend golfer who wants outside eyes on his swing is not admitting failure. He is copying the habit of every player he watches on Sunday.
What You Can Fix Yourself and What Needs a Coach
The honest division, from two people whose living sits on one side of it.
Yours to fix alone: grip, aim, ball position, posture, and effort level. Everything in the lesson-tee list above is checkable with two clubs, a chair, a can of spray, and a phone, and those five items cover a remarkable share of amateur misery. Tempo belongs to you as well; counting a slow two on the backswing and one through the ball costs nothing and rescues more swings than it gets credit for.
Coach territory: anything involving how your path and face interact through impact, the sequencing of body and arms on the downswing, and any fault that has survived three of your own honest fix attempts. Survival through three attempts is the tell that you have been treating a symptom, and a single swing consultation that names the real cause will save you a season of polishing the wrong move. The same goes for any change you have rehearsed for a month that refuses to appear on video; at that point you need eyes, not effort.
Work in the Right Order
Improving a golf swing stops being mysterious when the sequence is right. Read the ball flight pattern first, because it names the face and path problem. Check the strike with spray, because centered contact has to come before shape. Hunt the first domino in your grip, aim, ball position, effort, or posture before touching anything downstream. Install one change at a time, exaggerated, slow, and on camera. And hand the face-path and sequencing work to a trained eye when your own three attempts have not moved it.
That is the entire method, and most of it costs less than a sleeve of golf balls. For players around Chicago’s western and southwest suburbs, from Lombard across to the Palos area, this diagnostic chain is exactly what the first half hour of our one on one lessons looks like, indoors all winter and on grass all season. For everyone else, the ball, the spray can, and the camera will tell you most of what we would, as long as you read them in order.
