How to Fix Early Extension in the Golf Swing
Quick answer
Fix early extension by keeping your trail-side glute and hips turning back and down instead of thrusting forward toward the ball. Build real backswing depth, then use wall or chair contact drills to feel your pelvis stay back through impact. This preserves spine angle so the club has room to release without you standing up.
Early extension is when your hips and pelvis push toward the ball during the downswing instead of rotating and staying back. Your spine straightens up, your posture from address disappears, and there's suddenly less room for your arms and the club to get through impact. The body has to improvise: usually with a block, a thin shot, a flip through the hitting area, or an occasional shank.
It's one of the most common faults in amateur golf because it's often a compensation, not the original problem. Something earlier in the swing (a shallow backswing turn, weak glutes, a bad setup posture, or a trail side that fires toward the ball too soon) leaves no space to deliver the club on plane. Standing up is the body's fallback solution for that lack of space, even though it wrecks strike quality and consistency.
Because several different root causes all produce the same visual (hips thrusting, posture lost), fixing it works best when you know which one applies to you. A down-the-line video or an AI swing analysis can confirm whether your early extension comes from poor backswing depth, a transition sequencing fault, or a setup posture issue, so you're drilling the actual cause instead of just the symptom.
Why it happens
Not enough backswing depth (a flat, arms-only turn)
If the hips and trail glute don't turn back and away from the ball on the backswing, there's no room left in the downswing to drop the club into the slot. The body's only remaining option to create space is to stand up and shove the pelvis toward the ball: early extension is often just the body solving a space problem it created earlier in the swing.
Trail side fires toward the ball in transition
Instead of the lead hip rotating and clearing back and around, the trail hip and knee thrust laterally toward the target. This 'stuck' pattern jams the arms against the body, and the only way to avoid a shank or block is to straighten up and push the pelvis forward, which is early extension by definition.
Weak or inactive glutes and core
Holding spine tilt and a bent-knee posture through impact takes real muscular tension in the glutes and trunk. When those muscles switch off, the body reflexively stands up into a stronger, more stable position (straight legs and an upright spine), sacrificing posture for stability.
Poor setup posture (S-posture or C-posture)
An excessive lower-back arch (S-posture) or rounded upper back (C-posture) at address leaves no efficient path to rotate the hips deeply. The player compensates during the swing by extending out of the faulty posture, which reads as early extension even though the real fault started before the club ever moved.
Trying to manufacture power by pushing up instead of rotating
Some golfers associate power with extending the legs and driving upward, like a vertical jump. Real clubhead speed comes from rotational force into the ground and through the hips, not from standing up. Chasing power this way trades compression and consistent strike for a few extra, mishit yards.
How to fix it, step by step
- 1
Feel the fault first with a beginner-friendly wall drill
Start with the Wall Drill For Early Extension. Cross your arms, stand six inches from a wall, and keep your rear end lightly on the wall from address through the top of the backswing and into transition. If your hips leave the wall, you've early extended: this gives you an unmistakable, immediate reference for what staying in posture actually feels like.
- 2
Hold the feeling into impact with the Chair Drill
Set a chair or golf bag against your glutes at address and keep light contact with it through downswing, impact, and follow-through. Start with half swings using the Chair Drill for Early Extension before building back up to full shots, so the new pattern survives contact with a real ball.
- 3
Add real hip depth with the wedge feedback drill
Place a wedge under your trail heel and make full swings using the Trail Heel Wedge Drill. Focus on pulling the lead hip back to match the trail hip in the downswing. If the trail heel lifts off the wedge, you've thrust forward instead of rotating: the wedge tells you instantly.

Fix a flat backswing turn if that's your root cause
If you're not turning your hips deeply going back, work the Right Toe Lift Drill. Lifting the trail foot's toes as you swing back forces the trail hip to clear space behind you, which removes the need to manufacture room later by standing up.
- 5
Retrain the downswing sequence if your trail side fires early
If video shows your trail hip or knee driving toward the ball in transition, work through the checkpoints in Why Amateur Golfers Can't Stay Down & Rotate In The Downswing: the banked-foot feel, the knee-block stick, and the belt-loop rotation drill all target this specific 'stuck' pattern that leads straight into early extension.
- 6
Stress-test the fix with a stricter feedback drill
Once the move holds up at half speed, raise the standard with the Tailbone Alignment Rod Drill. Any daylight between your tailbone and the rod at impact means the fault is still there: this is a good final checkpoint before taking the change to the course.

Frequently asked questions
Why does early extension show up with driver but not with irons?
Driver is swung on a flatter, shallower plane with the ball played forward, which tempts golfers to help the ball into the air by standing up through impact. Irons are hit with a steeper, more descending strike where staying bent over is more instinctive. The underlying fault is often present with both clubs: it's just easier to see and more costly with the driver.
How long does it take to fix early extension?
Most players feel the correct move in a single range session using a contact drill like the wall or chair drill, but making it hold up under full-speed swings and on the course takes several weeks of repetition. Start with slow, half-speed swings and only add speed once the posture holds without thinking about it.
Can weak glutes really cause early extension?
Yes. Staying in your posture through impact requires the glutes and core to hold tension against the forces of the downswing. If those muscles are weak or don't fire in sequence, the body defaults to standing up because it's a more stable, lower-effort position.
Does early extension cause thin or fat shots?
Both, depending on timing. Standing up early raises the low point of the swing before the club reaches the ball, which usually leads to thin, bladed contact. Some players compensate by flipping their hands to catch up, which can also produce fat shots or inconsistent strike depth.
Can early extension cause a shank?
Yes. When the hips thrust toward the ball, the arms and hands get pushed away from the body, moving the clubhead's hosel closer to the ball's flight line. That's a direct setup for a shank, which is why some early extension drills double as anti-shank work.
Do I need a lesson to fix this, or can I do it with video and drills?
Plenty of players fix early extension with drill work and honest feedback from video, since the fault is visible from a down-the-line angle. A face-on or down-the-line recording (or an AI swing analysis) is genuinely useful here because it tells you which of the root causes above applies to you, so you're not guessing at a fix that doesn't match your swing.
