Maintain Spine Angle with the Windmill Drill

The windmill drill teaches you how to turn your body while maintaining your original posture. If you tend to stand up, dip down, or lose your spine angle during the backswing, this is a simple visual drill that can clean up your motion quickly. It is especially useful if you learn best by seeing where your body should be in space rather than thinking about a long list of swing positions. The goal is to help you pivot correctly so your upper body stays tilted as you turn, instead of moving like a Ferris wheel or spinning flat like a helicopter.

How the Drill Works

To do the drill, start by getting into your normal golf posture. From there, stretch your arms straight out to your sides so your body forms a wide “T” shape. Your arms are not holding a club here—they are simply acting as visual guides.

Once you are set, make a backswing turn while keeping your posture intact. If you are rotating correctly, the arm that is working down toward the ball side should appear to point roughly at the golf ball. Then, as you turn through, the opposite arm should again point down toward the ball.

This is why the drill is called windmills. Your body should rotate on an angle, like a tilted windmill. That angle matters. If you rise up too much, your body starts looking like a Ferris wheel—too vertical. If you turn too level to the ground, it looks more like a helicopter—too flat. The correct motion is between those two extremes.

The drill gives you an immediate visual reference for whether you are preserving your spine angle as you pivot. For many golfers, especially beginners, that makes it much easier to understand what a proper body turn should look and feel like.

Step-by-Step

Set up in your normal golf posture. Bend forward from your hips the way you would at address, with your knees softly flexed and your chest tilted over the ball.
Extend both arms straight out to your sides. Your arms should form a wide line across your shoulders, like airplane wings.
Use a golf ball as a reference point. Place a ball on the ground in front of you where you would normally address it. This gives you a clear visual target for your arm line.
Turn into your backswing. Rotate your torso while staying in posture. As you do, the arm on the ball side should work down so it appears to point toward the ball.
Turn through to the follow-through. Continue rotating to the other side. Now the opposite arm should point down toward the ball.
Move slowly at first. This is a body-awareness drill, not a speed drill. Go back and through in a controlled way so you can clearly see whether your arms are tracing the proper tilted pattern.
Repeat for several reps. Make slow rehearsals until the angled turning motion starts to feel natural.

What You Should Feel

When you are doing the drill correctly, you should feel your body rotating around your posture, not coming out of it. Your chest stays inclined forward while your torso turns back and through.

Here are the main sensations to look for:

Your upper body stays tilted forward instead of standing upright during the turn.
Your arms trace an angled circle, not a vertical one and not a flat one.
Your ribcage and shoulders do the turning while your posture remains stable.
The arm line points roughly toward the ball in both directions of the pivot.
Your movement feels centered, with rotation happening around your spine angle rather than away from it.

A good checkpoint is simple: if your arms are no longer matching up with the ball as you turn, you have probably changed your posture. Either you stood up, dipped excessively, or leveled out your turn too much.

Common Mistakes to Avoid

Standing up in the backswing. This is the Ferris wheel look. If your chest rises and your arms work too vertically, you are losing your spine angle.
Turning too flat. This is the helicopter look. If your shoulders rotate level to the ground, you are not turning on the angle created at address.
Bending more as you turn. Some golfers do not stand up—they do the opposite and dip down too much. That is still a loss of posture.
Moving too fast. If you rush the drill, you lose the visual feedback that makes it effective.
Using only the arms. The drill is about your body pivot. Your arms are just references, not the source of motion.
Starting from poor posture. If your setup is off, the drill will train the wrong angle. Begin from a sound golf posture every time.

How This Fits Your Swing

Maintaining your spine angle is one of the foundations of a reliable pivot. When you keep your posture as you turn, your swing becomes easier to repeat because the club can travel on a more predictable path. You are also more likely to return to the ball consistently, which helps with both contact and direction.

If you lose posture in the backswing, compensation usually follows. You may have to reroute the club, throw your arms at the ball, or make last-second adjustments just to find impact. That often leads to fat shots, thin shots, pushes, pulls, and inconsistent strikes.

The windmill drill helps you build the correct body motion before you even put a club in your hands. It teaches you that the golf swing is not just a turn—it is a turn on an inclined angle. Once you understand that visually and physically, it becomes much easier to make a backswing that stays centered and organized.

As you improve, you can use this drill as a rehearsal before hitting balls. Make a few slow windmill turns, feel your body rotating while preserving posture, then step in and try to carry that same tilted pivot into your actual swing. Over time, this can help you eliminate one of the most common backswing problems: losing your posture and forcing yourself to recover on the way down.
