Improve Your Impact Position with the Famous Line Drill

The line drill is one of the simplest ways to improve your impact position and clean up fat or thin contact. It gives you immediate feedback on where the club is actually striking the ground, which tells you whether your low point is in the right place. With irons and wedges, you want the club to contact the ball first and the turf second, which means the bottom of the swing needs to be slightly forward of the ball. If your swing bottoms out too far back, you tend to hit behind the ball, catch it thin, or strike it low on the face. This drill helps you train the correct flat spot through impact so your contact becomes much more predictable.

How the Drill Works

The setup is very simple: place a visible line on the ground somewhere around the middle of your stance, usually a little forward of center to represent the ball position for an iron. That line becomes your reference point.

You can create the line in several ways:

A piece of string laid on the ground
White tape or chalk
Spray paint on a practice area
A trench lightly carved with a tee

The goal is not to hit the line itself. The goal is to make your swing so that the club enters the ground just after the line. If the line represents the ball, then a divot beginning in front of it means you would have struck the ball first and then taken turf.

That is the key to solid iron contact. A good player’s low point tends to be more forward, closer to the target side. Higher-handicap players often let the club bottom out too early, more toward the trail foot, which leads to inconsistent strikes. The line drill makes that pattern visible right away.

It also teaches an important part of the swing called the flat spot through impact. You are not trying to chop steeply into the ground. You are learning to let the club travel through the ball with the handle and body organized well enough that the turf interaction happens in front of the ball position.

Step-by-Step

Create a clear line on the ground. Use a tee to scrape a narrow line in the turf, or use chalk, tape, or string if that is easier. Make sure you can see it clearly.
Set up as if the line were the golf ball. Take your normal iron stance and place the line where you would normally position the ball, typically a little forward of center.
Make a practice swing without a ball. Focus on brushing the turf so the divot starts just in front of the line. You are training where the club reaches the bottom of the arc.
Check the ground immediately. Look to see where the club first entered the turf. If the divot starts behind the line, your low point is too far back. If it starts just after the line, that is what you want.
Repeat until you can do it consistently. Do not rush to full speed. Start with short swings, then build to three-quarter and full swings as your strike improves.
Add a ball once your strike pattern is reliable. Place the ball on the line and try to reproduce the same turf interaction. The ball should be struck first, with the divot beginning after it.

What You Should Feel

When you do this drill well, the swing should feel organized through impact rather than forced. A few sensations can help:

Pressure moving forward into your lead side by impact
The handle slightly ahead of the clubhead at strike with irons
The chest continuing to turn through the shot instead of stalling
The club brushing the turf after the line, not crashing into the ground early
A shallow, forward divot rather than a deep gouge behind the line

You should also notice that the strike feels more compressed. Even without a ball, a correct swing through the line tends to sound and feel cleaner. Once you add a ball, solid shots usually come off the face with a much more centered strike.

A useful checkpoint is this: if the line represents the ball, your divot should begin in front of it nearly every time. That is a strong sign that your impact alignments are improving.

Common Mistakes to Avoid

Putting the line too far back in your stance, which makes the drill less realistic for iron impact
Trying to help the ball up by leaning back and adding loft, which moves the low point behind the line
Hanging on the trail foot instead of shifting pressure forward
Flipping the clubhead past the hands through impact, which often leads to thin or heavy contact
Stopping body rotation and relying only on the arms
Digging too steeply in an effort to “hit down” rather than letting the club move through with a proper flat spot
Judging one swing instead of a pattern; look for consistency over several repetitions

How This Fits Your Swing

This drill is not just about making a divot in the right place. It connects directly to the bigger pieces of a good swing. Solid contact depends on controlling the club’s low point, and low point control depends on how your body and arms are organized through impact.

If you struggle with fat and thin shots, the line drill helps you identify whether the real issue is that the swing is bottoming out too early. If you can train the club to reach the turf after the ball position, you are building a better impact pattern: forward pressure, better shaft lean, and a more reliable strike.

It also reinforces the idea that good contact is not random. The club is designed to strike the ball with the sweet spot when the handle is slightly forward and the club is still moving downward with irons. The line drill gives you a visible way to practice that instead of guessing.

As your skill improves, this drill becomes a checkpoint you can return to anytime your contact starts slipping. If the divot starts behind the line, you know your impact conditions need attention. If the divot consistently starts after the line, you are much closer to the kind of impact position that produces crisp, compressed iron shots.
