How to Swing a Golf Iron

By Spencer Lanoue
July 24, 2025

A pure iron shot feels incredible - that compressed thump as the ball leaves the clubface is the sound of a job well done. But getting there can feel confusing. This guide breaks down the iron swing into simple, manageable pieces. We’ll cover everything from how you stand to the ball to your finish position, giving you the building blocks for power, accuracy, and that satisfying strike you’re looking for.

The Basics: How to Hold the Golf Club

Your grip is the only connection you have to the club, so it’s your steering wheel. An incorrect hold forces you to make other complicated adjustments in your swing to hit the ball straight, making a hard game even harder. So, let’s get this right from the start.

First, get the clubface square. You can use the logo on the grip manufacturer as a guide, or simply look at the leading edge of the clubface and make sure it’s perfectly vertical. This is your baseline.

The Top Hand (Left Hand for Righties)

Now, let your left hand approach the club from the side. Your palm should be facing slightly inwards in a natural position. Don’t try to twist it too far over or under the grip. Here’s how to place it:

  • Hold it in your fingers. The grip should run diagonally from the base of your little finger to the middle part of your index finger. This gives you more control and feel.
  • Fold your hand over the top. Once the fingers are set, simply close your hand over the top.
  • Check your knuckles. Looking down, you should be able to see two knuckles on your left hand. If you see three or four, your grip is too “strong” (rotated to the right), which often causes hooks. If you can only see one or none, it’s too “weak” (rotated to the left), often leading to slices.
  • Check the "V". The "V" formed by your thumb and index finger should point up toward your right shoulder.

Just a quick warning: for many new golfers, and even experienced ones making a change, a correct grip feels weird. It feels uncomfortable and different from how you hold anything else. Trust the process, your hands will get used to it.

The Bottom Hand (Right Hand for Righties)

Your right hand mirrors the left in its natural approach. The palm should face the target, slightly inwards. A simple way to get it right is to place the main pressure point - the lifeline/pad on your right palm - directly on top of the left thumb that’s already on the grip. From there, your fingers just wrap naturally around the club.

As for connecting the hands, you have three popular options:

  1. Ten-Finger (or Baseball) Grip: All ten fingers are on the club. This is great for beginners or those with weaker hands.
  2. Interlock Grip: The pinky of your right hand links with the index finger of your left hand.
  3. Overlap (or Vardon) Grip: The pinky of your right hand rests in the space between the index and middle finger of your left hand.

Honestly, it doesn’t matter which of these three you choose. Pick the one that feels most comfortable and secure, helping your hands feel like they are working together as a single unit.

Setting Up for Success: Your Iron Address Position

Standing to a golf ball correctly feels… strange. You lean over an amount that seems exaggerated, with your bottom stuck out. This an athletic, yet structured posture, and it’s the foundation for a repeatable swing. Embrace the weirdness - it’s what good golfers look like.

Building Your Stance

Follow this sequence to get set up consistently every time:

  1. Aim the Clubface First: Before you take your stance, place the clubhead behind the ball and aim it directly at your target. This is the most important part - get the club pointing where you want the ball to go.
  2. Bend From Your Hips: Now, tilt forward from your hips, not your waist. Your back should stay relatively straight as you lean over, which will naturally cause your bottom to stick out. Think about creating a solid base.
  3. Let Your Arms Hang: Lean over just enough so your arms can hang down naturally and comfortably from your shoulders. If you stand too upright, your arms will be jammed into your body. If you lean too far, you'll feel off-balance reaching for the ball.
  4. Set Your Stance Width: For a mid-iron, a stance about shoulder-width apart is perfect. It gives you a stable enough base to rotate your body powerfully without restricting your hip turn. A stance that’s too narrow or too wide will prevent you from turning properly.
  5. Check Your Weight: Your weight should be balanced 50/50 between your feet. Don’t lean too much on your toes or your heels. Feel grounded and athletic.

Lastly, relax. Take a second to release any tension in your arms, shoulders, and hands. A tense golfer can’t make a fluid, powerful swing.

Ball Position

Where you place the ball in your stance changes slightly depending on the iron you’re hitting. Here’s a simple rule of thumb:

  • Short Irons (Wedge - 8-iron): Place the ball directly in the middle of your stance, right under the buttons of your shirt.
  • Mid- and Long Irons (7-iron - 4-iron): Move the ball slightly forward of center - maybe a ball or two toward your front foot.

This subtle adjustment helps you catch the longer clubs on a slightly shallower part of the swing arc, promoting a better launch.

The Backswing: Storing Power and Maintaining Control

A good backswing is not about lifting the club with your arms, it's a rotational movement powered by your body. Think of your body coiling like a spring. The goal is to turn smoothly around your spine while staying centered over the ball.

Keep it Connected

Imagine you’re standing inside a barrel. As you make your backswing, you want to rotate your shoulders and hips without swaying or bumping into the sides of the barrel. The first move away from the ball should be a one-piece takeaway - your arms, hands, shoulders, and hips all start turning together.

A Little Wrist Hinge Goes a Long Way

As the club gets to about waist-high, allow your wrists to start hinging upwards naturally. This isn't an aggressive, conscious action, it's a soft setting of the club. This small move is powerful because it sets the club on the correct plane. Without it, golfers often swing the club too far around their body ("getting stuck") or lift it too vertically. Both create problems on the way down.

How far should you go back? Go back until you feel a comfortable turn in your torso. That’s your limit. Don't feel like you need to get the club to parallel to the ground if your body can't turn that far. A shorter, controlled turn is always better than a long, out-of-control one. The goal is to reach the top of your swing in a strong, balanced position, ready to start the downswing.

The Downswing and Impact: Unleashing Your Power

You’ve coiled your body and stored up energy. Now it's time to deliver it to the golf ball. The key to a powerful and consistent iron strike is the sequence of movements from the top.

The first move is NOT an aggressive unraveling with the arms. The first move down is a slight shift of your lower body toward the target. As you start the downswing, your hips subtly move to the left (for a righty). This shift does two very important things: it gets your weight onto your front foot, ensuring you hit down on the ball (ball-first, then turf), and it clears your body out of the way so your arms have space to swing freely.

Once that small shift happens, your body can begin to unwind powerfully. Thinking "back to the target, through to the target," just let your chest and hips rotate open towards where you want to go. This rotation is your engine. Many amateurs make the mistake of trying to help the ball get into the air by hanging back on their right foot and trying to lift it. Let the loft on the club do its job! Your job is to shift forward and turn through the shot.

The Follow-Through: Balancing for a Picture-Perfect Finish

What happens after you hit the ball is just as important as what happens before. A good follow-through is a sign of a good swing - it shows you’ve transferred your energy efficiently and stayed in balance.

Don't stop your rotation at impact. Keep turning your hips and chest all the way through until your chest is facing the target. As your body rotates, your right heel will naturally lift off the ground, and your weight will finish almost entirely on your left foot. Think about finishing with the club wrapping comfortably around your neck or shoulders and holding that balanced pose. Challenge yourself to hold your finish until the ball lands. This single thought can fix a lot of swing flaws, as it forces you to stay balanced and complete your turn.

Final Thoughts

Building a solid iron swing comes down to embracing a few core feelings: a stable, athletic setup, a rotational turn on the backswing, a smooth shift-then-unwind sequence on the downswing, and a full, balanced finish. Focus on just one of these elements at a time at the range, and you’ll start building the consistency and power you want from your irons.
