Reduce Early Extension by Getting Under the Shaft

If you tend to early extend in the downswing, your hips move toward the ball, your chest stands up, and your hands get pushed high and away from you. That pattern makes it hard to deliver the club consistently. The Get Under the Shaft drill gives you a simple visual barrier that teaches the opposite motion: keep your chest inclined, avoid driving the pelvis forward, and let your hands work lower through impact. It is not a speed drill. It is an awareness drill designed to help you understand the space your body and arms need in the downswing.

How the Drill Works

For this drill, you place an extra golf shaft on the ground so it acts like a guide for your hand path. Set it at roughly the same lie angle as your club, but do not place it directly on your club’s path. Instead, position it slightly behind and slightly ahead of the ball line so there is just enough room for your hands and club to pass under it.

A good starting point is to place the shaft about six to eight inches back from the ball on the target line and about three to four inches forward on the lead side. That creates a slanted barrier that visually represents the high, outward hand path you are trying to avoid.

When you early extend, your lower body moves closer to the ball and your upper body responds by backing up. As that happens, the handle rises and your hands move out toward the shaft. In many cases, you will feel as if you are almost running into the barrier.

When you do the motion correctly, the pelvis does not thrust forward, your chest stays down longer, and your arms can shallow and work lower through the strike area. The result is that your hands and club travel underneath the shaft with room to spare.

Because this is mainly a visual and spatial-awareness drill, you do not need to hit hard shots. Short, slow-motion swings are usually best. If you use a bare shaft, add padding such as a swim noodle, or make sure it is positioned safely so accidental contact is not an issue.

Step-by-Step

Set the barrier. Place an extra shaft at about the same angle as your club’s lie angle. Position it roughly six to eight inches behind the ball line and three to four inches forward of the ball so there is space for your hands to pass underneath.
Start with a short club and a slow motion. Use a wedge or short iron and make rehearsal swings first. This drill is about movement quality, not power.
Make your normal backswing. Do not try to manipulate the club early. Let the backswing feel natural.
Begin the downswing by keeping your posture. Feel your chest stay inclined toward the ball rather than standing up. At the same time, avoid pushing your hips toward the ball.
Let your hands work lower. As you transition down, feel the handle and your hands travel under the shaft instead of rising into it.
Make small through-swings. Start with half-swings or pump rehearsals. If you can move under the shaft consistently, gradually lengthen the motion.
Add light contact. Once the movement is clear, hit soft shots while maintaining the same body alignments and hand path.

What You Should Feel

The biggest sensation is that your upper body stays in the shot longer. Instead of your chest backing away from the ball, it feels as though it remains more pointed down through the strike.

You should also feel that your pelvis stays back rather than jumping toward the ball. Some players describe this as keeping their rear end back or feeling a slight lowering of the pelvis in transition instead of a forward thrust.

In your arms and hands, the key feeling is that the handle works lower and more around, not up and out. If you are used to early extending, this may initially feel exaggerated. That is normal. The drill is helping you sense a hand path that is very different from your old pattern.

Use these checkpoints:

Your hands pass under the shaft, not into it.
Your chest remains more inclined toward the ball through impact.
Your hips do not move noticeably closer to the ball in the downswing.
The club feels as if it has room to approach from the inside without your handle lifting.

Common Mistakes to Avoid

Swinging too hard. If you go full speed too soon, you will usually revert to your old pattern.
Placing the shaft incorrectly. If the barrier is too close, the drill becomes cramped. If it is too far away, it loses its purpose.
Trying to drop only the hands. Lower hands are the result of better body motion, not a forced arm action by itself.
Standing up through impact. If your chest lifts early, your hands will rise with it.
Driving the hips toward the ball. This is the core move that creates the problem in the first place.
Ignoring safety. Pad the shaft or keep it far enough away that accidental contact is harmless.

How This Fits Your Swing

This drill helps you connect body motion to club delivery. Early extension is not just a cosmetic issue. It changes how the club approaches the ball, often leading to blocks, hooks, thin shots, and heel strikes. When your pelvis moves forward and your posture is lost, your arms have to reroute the club at the last second.

By learning to get under the shaft, you train a downswing where your body creates space instead of taking space away. Your chest stays in posture, your hips stay back, and your hands can work on a better path through impact. That gives you a much better chance of delivering the club consistently.

Think of this drill as a bridge between a swing fault and a functional movement. It gives you an external reference you can see and feel. Once you can repeatedly swing under the barrier, you can begin blending that same motion into normal practice swings and then into full shots. Over time, the visual aid teaches you what a more efficient downswing should feel like, and that is what helps reduce early extension for good.
