Early Extension: Two Root Causes and the Trap of Symptom-Chasing Drills

January in Chicago, minus eight outside, and inside a netted practice bay on the outskirts of the city a 47-year-old man hit 27 thin shots out of 40 balls. Taped to his driver shaft was a sticky note with four words in block capitals: KEEP THE HIPS BACK. He had been doing the chair drill for six months, three sessions a week, as reliably as a commute. His hips still drove toward the ball, his chest still lifted, and the clubface still arrived at contact half an inch later than it was supposed to.

I sat at the end of the row and logged every rep. Not because I like counting. Because I have seen this pattern thousands of times in 23 years of covering sport, and it always wears the same clothes: a serious player, a correct cue, and a wrong outcome.

The error is that people treat symptoms with discipline. The more disciplined they are, the longer the error survives.

What actually happens when the pelvis thrusts

Early extension is the name for the pelvis pushing toward the ball during the downswing, destroying the posture angle established at address, lifting the chest and extending the spine early. The consequence is not aesthetic. The consequence is low point: it drifts up, it drifts forward, and the player is forced to compensate with the hands. That is why the same fault produces thin shots in one golfer, heel strikes in another, and a lost sense of compression in a third.

The instruction piece published by GOLF.com frames the problem against the grain of most online coaching content: it states plainly that the "keep your hips back" cue is insufficient, and it calls early extension a compensation rather than a root fault. It names two causes: a downswing plane that is too steep, over-the-top style, and pressure retained on the trail foot that blocks the pivot. The corresponding fixes are more backswing depth so the club arrives in a better position, and loading into the inside of the trail foot before shifting to the lead foot in transition. Rory McIlroy is used as the visual model, with a commendably responsible caveat: the recreational golfer does not need his flexibility.

I read the piece in a week when a few thousand more people in Vietnam picked up a club for the first time. The local boom is being built on short-form video, on living-room drills, on weekend tee times and word-of-mouth cues. A beginner in Hanoi or Dong Nai today has more information than I had in 2026, but far less chance of having someone measure his foot pressure and slow-motion his downswing plane. Which means he is primed for exactly the trap the article is trying to disarm: hear a cue, practise it diligently, never ask why the body insists on doing the opposite.

Cause one: the body makes room for a swing that has none

When the downswing plane is too steep, the club arrives from outside the ball line and steeper than required. If the player holds his address posture and keeps the pelvis still, the clubface will bury itself in the ground behind the ball. The body does not negotiate with willpower. It finds a way to survive.

That way is thrusting the pelvis forward, lifting the chest, and dragging the arms down awkwardly. The article calls this an athletic reaction rather than a conscious choice. I agree, and I would put it more strongly: if the club keeps arriving on a plane that does not fit, every attempt to hold the hips back is a fight between intention and reflex — and reflex always wins at 150 km/h.

The proposed fix is more backswing depth, so the club has a better plane to arrive on and the body no longer needs to manufacture space. That logic is correct and it is hard, because it changes the root rather than the branch.

One addition from my own observation. Backswing depth and sway look identical on a phone video and behave nothing alike. Real depth preserves trail-knee flex and keeps pressure from leaking to the outside of the trail foot. Sway does not. A great many players told to "turn more" have traded early extension for a sway, then a sway for a reverse pivot, and finally returned to early extension convinced they are beyond help.

Cause two: the trail foot is an anchor nobody sees

Less discussed on the practice tee and more subtle: pressure retained on the trail foot. The player loads and never releases. The pelvis is anchored behind him, the arms are trapped behind the hips, and the only remaining exit is to stand up.

The fix described is to load into the inside of the trail foot and then shift to the lead foot in transition. I emphasise the word transition, because this is where amateurs most often fail. They shift at the start of the backswing and produce an empty turn, or they wait until the club is already at hip height and by then it is far too late.

The ground-reaction-force wave has become the dominant lower-body teaching paradigm since force plates entered mainstream coaching. Which means this article stands on a framework it does not cite. For a reader without measurement equipment, a feel-based description is all he has, and foot-pressure feel is among the hardest sensations to teach without quantitative feedback.

This is where McIlroy enters. In his action, pressure moves to the lead side very early, the lead foot effectively re-plants while the club is still travelling down, and the pelvis rotates open to create room for the arms rather than consuming it. A number never tells the whole story, but it always knows how to open one: four majors — the 2026 U.S. Open at Congressional with 268, a championship record; the 2026 PGA Championship at Kiawah; the 2026 Open Championship at Royal Liverpool; the 2026 PGA Championship at Valhalla. Born 4 May 2026. All of it built on a pelvis most amateurs do not own anatomically.

The article recognises this and says so explicitly. That is responsible framing, and the author deserves credit for not selling a fantasy of imitation.

What the article does not say: how to know which group you are in

This is where I want to slow down, because it decides the practical value of the whole piece.

The two causes do not coexist in one player at random rates. They map onto two different populations, with two different ball flights, requiring two different interventions.

The first is the steep-plane player, typically a slicer, higher handicap, club approaching from out to in. For him, fixing the plane is priority one.

The second is the better player hitting thin shots, losing compression, feeling as though he is hanging back. For him, the problem sits in the pressure sequence and the timing of the shift, not in backswing depth.

The article presents both causes as an additive fix set. In reality, applying both at once to an undiagnosed golfer is the fastest way to manufacture a new and more organised fault.

Three further factors go unmentioned, and I rate them as heavily as the two that are named.

First, face-control compensation. A player who cannot square the face with his hands will thrust the pelvis to buy time. Fixing the plane without fixing face control is chasing the ball from one corner to another.

Second, physical restriction. Limited hip internal rotation, limited thoracic extension, limited ankle dorsiflexion — all three generate early extension as a substitute for range of motion that does not exist. For this group, technical work before mobility work is putting the cart before the horse.

Third, fitting. A shaft that is too long, a lie angle too upright, or a shaft too heavy forces the player to stand up to return the face to the ball. This is the most common reason a correct technical change fails to hold beyond three weeks.

The contrarian read: the wall drill is not useless, but it does not cure anything

The strongest passage in the piece is the author's self-critique of the industry's most popular tool: the chair or wall drill used to feel the hips staying back.

The article states plainly that it teaches awareness and does not address causation. When the curtain falls, the truth begins. I want to push that observation one step further, to where I think the piece stops short.

The caveat "you don't need McIlroy's flexibility" is correct in principle and dangerous in practice. For a meaningful share of amateurs, restriction is the cause, and being handed a reasonable exemption persuades them to skip the physical screen — the one step that could show them the problem was never technical.

I also want to name the economics of this genre, because it explains why instruction pieces reliably omit three things: diagnosis, dosage and feedback criteria. Instruction content is one of the few golf-media categories untouched by the split between rival tours, it does not expire with the season, and it does not decay week to week. Its value lies in evergreen reach, not clinical precision. Commercially good instruction applies to everyone; technically good instruction states clearly who should not apply it.

And there is a risk the article does not flag. Over-emphasising backswing depth produces sway. Over-emphasising the lead-side shift produces a slide, low-point drift and a new fat-strike pattern. Neither is smaller than early extension. Both are harder to see, because both look like diligence.

What remains after the club has stopped moving

Where people assume there is only passion, I find the mathematics of the ball. In that mathematics, early extension is a dependent variable, not an independent unknown.

Based on my experience watching hundreds of practice sessions and dozens of tournaments, amateurs fail not for lack of effort but for lack of diagnosis. They are handed a cue, they execute it with admirable discipline, and their body — smarter than the cue — keeps doing the only thing that gets the ball struck.

Sport is unfair, but it always hands you a microphone to retell the truth. The truth here is uncomfortable in its simplicity: the swing is a negotiation between what the body can give and what the ball demands. Change the outcome and you must change one of the two sides. And either side needs measuring before it needs fixing.

If it takes six months to memorise a wrong cue, how long does it take to learn to listen to the one thing that has never lied to you — your own feet?
