The P3 golf swing position is the halfway-back checkpoint where your lead arm is parallel to the ground. Here are the five checkpoints to look for, the faults that break it, and the drills that fix it.
The P3 golf swing position is the halfway-back checkpoint: the moment in your backswing when your lead arm is parallel to the ground. It’s the first point in the swing where your arms, your body and the club all have to agree with each other. If they do, the top of your backswing tends to take care of itself. If they don’t, you start improvising.
I’ve taught golf around Chicago for seven years, and when a student’s backswing looks messy at the top, I almost always rewind the video to P3. The mess usually started here, or one checkpoint earlier. This guide covers what a good P3 looks like, the five checkpoints I use, the faults I see most often, and simple drills to fix them.

Where P3 Fits in the P-System
The P-system splits the swing into ten checkpoints, from address (P1) to finish (P10). P3 is the third. It comes after the takeaway and before the top of the backswing.
| Position | What it is |
|---|---|
| P1 | Address, before any movement |
| P2 | Takeaway, shaft parallel to the ground going back |
| P3 | Halfway back, lead arm parallel to the ground |
| P4 | Top of the backswing |
| P5 | Lead arm parallel to the ground coming down |
| P6 | Shaft parallel to the ground in the downswing |
| P7 | Impact |
| P8 | Shaft parallel after impact |
| P9 | Lead arm parallel in the follow-through |
| P10 | Finish |
Think of P2 and P3 as one continuous motion that coaches freeze at two points. At P2 the shaft is parallel to the ground. At P3 your lead arm is. If you haven’t read our guide to the P2 takeaway position, start there, because most P3 problems begin in the first eighteen inches of the swing.
What the P3 Golf Swing Position Actually Is
P3 happens when your lead arm reaches parallel to the ground on the way back. For a right-handed golfer, that’s your left arm. Coaches also call it the halfway-back or mid-backswing position.
It matters because it’s the first checkpoint where you can see how well your body and arms are working together. Your lower body should be stable, your upper body should be coiling over it, and your wrists should be starting to hinge. HackMotion’s breakdown of the P-system positions notes that this is where the wrist starts to hinge naturally, which is why wrist faults tend to show up here first.
One caution before we go further. P3 is a checkpoint, not a place to stop. Nobody pauses halfway back during a real swing. You’re looking at a single frozen frame of a motion that never stops, so the goal is to pass through a good position, not to hold it.
5 Checkpoints of a Good P3 Golf Swing Position
Freeze your swing when the lead arm is parallel and check these five things. Miss more than one and it’s worth spending a full range session on P3 alone.
1. Lead arm parallel, chest still turning
Your lead arm should be roughly parallel to the ground, and your chest should have turned away from the target along with it. If the arm is parallel but your chest still faces the ball, you’ve lifted the club with your arms.
This is the most common version of a bad P3. It feels fine in the moment because the club is moving, but your body has been left behind.
2. Hands over the chest, arms connected
From down the line, your hands should appear to cover your chest. They shouldn’t drift out in front of you, and they shouldn’t get tucked behind your back. Golf Inside UK describes elite players at this checkpoint as having their hands covering the chest, and I find that a handy mental picture for students.
Your arms should feel connected to your torso. They move because your body is turning, not because your shoulders are shrugging the club upward.
3. Shaft pointing just under your trail shoulder
Looking down the line, the shaft should point at a spot just under your trail shoulder, with the clubhead still outside your hands. That’s the same picture Golf Inside UK uses for good players at P3.
If the shaft points well outside that spot, the club is steep, and an over-the-top downswing is likely to follow. If it points well inside, the club is stuck behind you and you’ll have to reroute it on the way down.
4. Wrists hinging, lead wrist not cupped
Your wrists should be hinging as your arms swing up, with most of the hinge developing between P2 and the top of the backswing. What you don’t want is the lead wrist cupping, which means bending backward, early in the move.
HackMotion’s P3 notes call out early lead wrist extension as a fault that catches up to players at the top of the backswing. A flat lead wrist is the safer picture. Our guide to the left wrist in the golf swing goes deeper on this.
5. Stable lower body, trail side loading
Your lower body should stay quiet while your upper body coils over it. Your weight should be loading into your trail side, not swaying away from the ball.
If your hips have slid backward, or your lead knee has collapsed toward the ball, you’ll lose both power and consistency by the time you reach the top.
Common P3 Golf Swing Position Faults
Golf Inside UK makes a point I agree with: a poor P3 is nearly always the result of problems at P1 and P2. So before you work on P3 directly, make sure your address setup and takeaway are sound. With that said, these are the faults I see most.
Early lead wrist extension
The lead wrist bends backward, or cups, as the arm swings up. It can feel powerful, but it tends to leave the clubface open and forces a compensation later in the swing.
The fix is to keep the back of your lead hand and forearm in a straight line as you swing back. Let the hinge happen in the wrist’s natural up-and-down direction instead of rolling it backward.
Arms lifting without a body turn
Your hands and arms pick the club up while your shoulders barely move. At P3, the lead arm is parallel but your chest is still facing the ball.
The fix is to start the turn with your chest and let the arms follow. Our piece on the one-piece takeaway explains how to feel that sequencing from the first move.
Swaying instead of turning
Your weight slides away from the target and your head drifts with it. The lower body stops being a stable base, so the upper body has nothing to coil against.
The fix is to feel your trail hip turn back behind you rather than slide out to the side. Keep your lead knee flexed and press into the inside of your trail foot.
Club too steep or too shallow
A shaft pointing well outside your trail shoulder is steep. One pointing well inside is shallow. Both usually trace back to the takeaway, where an outside move creates the steep club and an inside move creates the stuck one.
Trying to fix the plane at P3 with your hands rarely works. Go back to P2, correct the first eighteen inches, and P3 will usually improve on its own.
How to Check Your Own P3
You can’t feel your way to a reliable P3. What feels halfway back to you is often nowhere near it, because the hands compensate without telling you. You need video.
- Down the line. Put the camera behind you on the target line at hand height. Check where the shaft points and whether your hands cover your chest.
- Face on. Put the camera level with your hands, square to the target line. This view shows chest turn, weight shift and whether your lead wrist is cupping.
- Same distance every time. Keep the camera in the same spot so you can compare this week’s swing to last month’s.
- Scrub frame by frame. Step through until the lead arm is parallel, then run through the five checkpoints above.
Drills to Build a Better P3
- Ball between the forearms. Hold a small soft ball between your forearms and make slow backswings to P3 without dropping it. HackMotion recommends this drill to keep the body and arms connected during this phase of the swing.
- Pause at P3. Make slow-motion backswings and stop when your lead arm is parallel. Check the five checkpoints, then continue the swing. Ten reps before each range session is plenty.
- Towel under both armpits. Tuck a small towel under each arm and make half swings to P3 without letting it drop. It trains the arms to move with your turn instead of lifting independently.
- Mirror check. Set up in front of a mirror and swing slowly to halfway back. Your hands should cover your chest, and your lead wrist should look flat, not cupped.
Keep these sessions short and frequent. Ten slow reps at every range visit beats one long overhaul that your body forgets by the weekend.
How P3 Connects to P2 and P4
P3 is the bridge between your takeaway and the top of your backswing. A clean P2 makes P3 easy. A good P3 sets up the P4 top-of-backswing position, where your wrists should be fully set and your trail side loaded.
If you tend to hinge your wrists too early, you’ll usually see it first at P3, when the lead wrist cups before the arm has even reached parallel. For the full picture of all ten checkpoints, our overview of ideal golf swing positions is a good companion read.
Frequently Asked Questions
What is the P3 position in golf?
P3 is the halfway-back checkpoint in the P-system, reached when your lead arm is parallel to the ground during the backswing. It comes after the takeaway (P2) and before the top of the backswing (P4).
Should my wrists be fully hinged at P3?
Not necessarily. HackMotion says the wrist starts to hinge naturally here, while Golf Inside UK describes elite players as having wrists almost fully set. For most amateurs, aim for hinge that is well underway at P3 and complete by the top.
Where should the club point at P3?
From down the line, the shaft should point at a spot just under your trail shoulder, with the clubhead outside your hands. Well outside that spot is steep, and well inside is shallow.
Why is my P3 so hard to get right?
Usually because the problem started earlier. A poor setup at P1 or a bad takeaway at P2 puts the club in the wrong place before you reach halfway back, and P3 simply makes the fault visible.
How do I stop cupping my lead wrist in the backswing?
Keep the back of your lead hand in line with your forearm as the arm swings up, and let the wrists hinge up and down instead of rolling backward. Slow-motion reps in front of a mirror are the quickest way to feel the difference.
Do I need video to check my P3?
It helps a lot. You can’t reliably feel whether your lead arm and chest are in sync, but a phone video from down the line and face on will show you in seconds.
Putting It Together
The P3 golf swing position isn’t flashy, but it’s the first checkpoint where your body, arms and club have to cooperate. Check the five markers: lead arm parallel with the chest turning, hands covering the chest, shaft under the trail shoulder, a flat lead wrist, and a stable lower body.
Film yourself from both angles, work the drills in short sessions, and resist the urge to steer the club with your hands. If P3 keeps looking wrong, go back to P1 and P2, because that’s usually where the fix lives.
