How to Turn the Shoulders in a Golf Backswing

A powerful, consistent golf swing is built around one fundamental move: the shoulder turn. Getting this right is the secret to generating effortless power and remarkable accuracy. If you get it wrong, you end up feeling like you’re fighting your own body, struggling to produce either. This guide will walk you through exactly how to turn your shoulders correctly in the backswing, breaking down the key movements, common flaws to avoid, and a few simple drills to make a great turn second nature.

Why Your Shoulder Turn is the Engine of Your Swing

Many golfers think the golf swing is an action performed with the arms and hands. It’s a natural assumption, since your hands are the only thing connected to the club. But the reality is that the arms are just along for the ride. The real power comes from your body’s rotation, with the shoulder turn being the primary driver of this engine.

Think of it like coiling a spring. A proper shoulder turn winds up the large, strong muscles of your upper back, core, and glutes. This creates tension and stores energy. The downswing is then simply the process of uncoiling this spring, releasing all that stored energy through the ball with massive speed. When you try to swing with just your arms, you’re using tiny muscles to do a big job. It leads to weak shots, fatigue, and all sorts of inconsistencies, most commonly a dreaded slice.

Beyond power, a good shoulder turn is also essential for control. It guides the golf club onto the correct path, or “plane,” allowing your arms to drop into the perfect position to deliver the clubhead squarely to the ball. When you simply lift your arms, the club gets steep and travels on an “over-the-top” path, cutting across the ball and putting slice-spin on it. A rotational turn gets the club traveling on a shallower, more rounded path, which is what lets you hit those solid, penetrating shots that feel amazing.

The Anatomy of a Great Shoulder Turn: A Step-by-Step Guide

Let's break down this crucial move into simple, repeatable pieces. Remember, the goal is rotation, not lifting. We want to turn our entire torso as a single unit.

Step 1: The One-Piece Takeaway

The backswing begins the moment the club moves away from the ball. The best way to start this motion is with what's called a “one-piece takeaway.” This means your hands, arms, and shoulders start moving back together, as a single unit. There shouldn’t be any independent wrist action or jerky hand movement right at the start. Imagine a triangle formed by your shoulders and arms at address. The goal of the takeaway is to move that triangle back together without changing its shape for the first few feet of the swing.

A great feeling for this is to focus on your chest. Turn your chest away from the ball, and let your arms and the club follow. This small move sets the entire backswing up for success by engaging the big muscles right from the get-go.

Step 2: Rotating, Not Lifting

After the takeaway, the main event begins. This is where many golfers make their biggest mistake: they start lifting their arms to get the club to the top. Instead, you need to continue focusing on turning your shoulders.

Here’s the number one thought to focus on: turn your left shoulder under your chin. For a right-handed golfer, your lead shoulder (the left one) is your guide. As you rotate back, feel that shoulder turning away from the target and moving down and under your chin. If you do this correctly, your back will naturally start to face the target. This turning motion is what pulls the arms and club up and around your body on the correct plane.

• Good feeling: Feel a stretch building in your upper back and lat muscles. This is the coil we’re looking for.
• Bad feeling: Feeling all the strain in your arms and shoulders, as if you’re lifting a heavy box.

Step 3: Creating the Proper Shoulder Tilt

A HUGE part of a successful shoulder turn is the tilt. Your shoulders should not turn level with the ground. Because you are bent over the ball in your golf posture, your shoulders have to turn on that same tilted angle.

As your left shoulder turns back, it should also move down towards the ground. At the same time, your right shoulder will move up and away from the ball. Imagine a line running across your shoulders. At the top of your swing, that line should be pointing somewhere between the golf ball and your toes. This downward tilt of the lead shoulder is what keeps you in your posture and prevents you from standing up during the swing, a common power-killer.

A level "merry-go-round" shoulder turn will get the club stuck behind you, forcing you to make compensations on the downswing that often result in hooks or blocks.

Step 4: A Fully Coiled Position at the Top

How far should you turn? Aim to get your back facing the target, or at least feel like you've made a 90-degree shoulder turn. For some players with more flexibility, they might get further, and for others, a little less is fine. The key is to turn as far as you can without losing your balance or your spinal posture.

When you reach the top, you should feel a distinct sense of being "loaded" or coiled into your right side (for a righty). Your weight should have shifted onto the instep of your right foot, and you’ll feel that spring-like tension across your upper body. From this powerful position, all you have to do is unwind and let it go.

The 3 Biggest Shoulder Turn Mistakes (and How to Fix Them)

Understanding what not to do is just as important as knowing what to do. Here are the most common faults nearly every golfer struggles with at some point.

Mistake #1: The All-Arms Lift

This is easily the most common fault. Instead of rotating their torso, the player simply lifts their arms straight up. This creates a swing that is narrow, steep, and powerless. It’s the leading cause of the over-the-top slice.

The Fix: Tuck a a headcover or a small towel under your in your lead armpit (the left armpit for a righty). Your goal is to keep it there throughout your backswing. To do this, you have no choice but to turn your body. If you just lift your arms, the towel will fall out immediately. This forces your arms and body to work together.

Mistake #2: The Sway

The sway is a lateral slide away from the target, rather than a rotation. The player’s hips drift outside their back foot, and the shoulders follow. This completely destroys the coil. Instead of winding up, you’ve simply shifted your weight off the ball, and from there it's very difficult to get back to hit it solidly and consistently.

The Fix: Find a wall or a golf bag. Set up so that your right hip (for a righty) is just touching it. Now, practice your backswing turn. Your goal is to turn so your right pocket moves straight back, away from the wall. Your right glute stays on the wall or close to it as it rotates, showing you are turning around your spine. If you sway, you’ll jam your hip into the object. This is a fantastic way to feel the difference between sliding and rotating.

Mistake #3: The Reverse Pivot

This is a nasty, power-robbing move where your upper body actually leans toward the target on the backswing, while your lower body slides away from it. It puts your weight on your front foot at the top of the swing, which is the exact opposite of what we want. From there, your only available move on the downswing is to fall backward, leading to weak contact, topped shots, and fat shots.

The Fix: Really focus on feeling your weight load into the instep of your trail foot (your right foot). A great visualization is to imagine you have a sensitive pressure plate under your trail foot. As you turn back, you want to feel the pressure increase on the inside part of that foot. This helps keep your weight centered and prevents that destructive backward lean.

Drills to Master Your Shoulder Turn

Feeling is believing in golf. You can read about the perfect turn all day, but these drills will give you the physical feedback you need to build it into your muscle memory.

1. The Classic Club-Across-Shoulders Drill

This is the gold standard for a reason. Grab a golf club and rest it across your upper chest, holding it in place with your arms crossed over it.

1. Get into your normal golf posture, nice bend from the hips.
2. Rotate your torso back just like you’re making a backswing.
3. Watch the grip end of the club. Your goal is to turn until the grip is pointing down at the golf ball, or even just past it.

This does two things perfectly: it confirms you’re making a full 90-degree turn, and it forces you to create the correct shoulder tilt. If you turn too level, the club will point well in front of the ball.

2. The "Back-to-Target" Drill

This is a simple feel-based drill you can do anywhere, even without a club. Get in your golf posture and just practice turning your back completely to your intended target. Have a friend stand behind you and check when they see the middle of your back. This helps override the instinct to stop the turn early and just lift the arms. You’ll be surprised at how much further you can actually turn than you think.

3. The Doorframe Drill

A great indoor option. Stand in a doorframe and get into your golf posture so your left hip is touching the left side of the frame. Now simulate your backswing. Your goal is to rotate your torso so that your right hip then makes contact with the right side of the doorframe. This simultaneously prevents you from swaying off the ball and ensures you make a complete hip and shoulder rotation.

Final Thoughts

Mastering the shoulder turn comes down to shifting your focus from lifting the arms to rotating the body. By getting your back to face the target and incorporating the correct degree of shoulder tilt, you’re building the foundational coil that creates effortless power and directs the club on a far more consistent path. Practice the fundamental moves and drills, and you'll trade flailing arms for a powerful, connected, and repeatable golf swing.
