A cupped wrist at the top of your backswing is one of the most common power-killers in golf, often leading to a nasty slice and frustrating inconsistency. If you feel like your swing lacks control and you're not getting the distance you deserve, there’s a good chance your lead wrist is the culprit. This guide will walk you through exactly what a cupped wrist is, why it's so damaging, and most importantly, provide you with actionable drills to fix it for good.
What is a Cupped Wrist and Why is it Robbing You of Power?
First, let’s be clear about what we’re talking about. For a right-handed golfer, a "cupped" wrist means your left wrist is bent backward, or extended, at the top of your backswing. If you were to hold your left hand out flat, palm-down, it would be the motion of bending your knuckles up towards the sky. The opposite of this is "bowed" or "flexed," where the back of your hand rounds towards the target. In between is a "flat" wrist, which is generally a solid, neutral position.
So, why is a little bit of a cup so bad? It all comes down to the clubface. When your lead wrist cups at the top, it pulls the clubface into an open position. An open clubface at the top of the swing means you have to make a heroic, last-millisecond manipulation with your hands and arms on the downswing just to get the club back to square at impact. This is an incredibly difficult move to time correctly.
The usual results of this compensation effort are:
- A Weak Slice: The most common outcome. You can't close the face in time, and you deliver a glancing blow, putting left-to-right spin on the ball.
- A Nasty Pull-Hook: Sometimes, in an over-correction, you flip your hands wildly to shut the face, pulling the ball far left.
- Loss of Power: When the clubface is open, you can't compress the golf ball effectively. It feels like a 'mushy' hit instead of a powerful, solid strike. The clubhead is not delivering its full force into the back of the ball.
- Total Inconsistency: Relying on timing to square the club is a recipe for disaster. One swing might be okay, the next is 40 yards right. Sound familiar?
A flat or slightly bowed wrist at the top, a position you see in nearly every professional golfer, keeps the clubface square or slightly closed. From this powerful position, you can simply rotate your body through the shot without having to think about manipulating the clubface. It simplifies the downswing immensely.
How to Tell if You're Cupping Your Wrist
You can't fix a problem until you know you have it. The best way to diagnose your wrist position is brutally simple: film your swing. You don't need a fancy camera, your smartphone will do just fine.
Set up your phone on a tripod or have a friend film you from a "down-the-line" perspective. That means they should be standing directly behind you, looking down the target line. Take a normal swing and then watch the recording in slow motion. Pause the video right at the very top of your backswing.
Look at the back of your lead hand (your left hand for a righty). Can you see a distinct angle or "crease" where it bends backward? Does it look like the picture of an open-faced sandwich? If so, you have a cupped wrist. Compare it to photos of players like Dustin Johnson (extremely bowed) or Tiger Woods (very flat). Your goal is to get much closer to their position.
The Common Causes of a Cupped Wrist
Just trying to brute-force a flat wrist might not work if you don't address what's causing it in the first place. For most golfers, the cup is a symptom of another issue in the swing. Here are the three most frequent culprits.
1. Your Grip is Too "Weak"
This is probably the number one reason golfers cup their wrist. A "weak" grip (and we're not talking grip pressure) is where your lead hand is rotated too far to the left, or "under" the handle. When you look down, you might only see one knuckle, or maybe not even that. A weak grip naturally wants to open the clubface during the backswing. To combat this, your body's self-preservation instinct forces the wrist to cup, trying to position the club in a more playable spot at the top. To fix this, look down at your grip at address. You should be able to see at least two, maybe two-and-a-half, knuckles on your lead hand. That V-shape formed by your thumb and index finger should point toward your trail shoulder (your right shoulder for a righty).
2. An "All Arms" Takeaway
A great golf swing starts with a "one-piece takeaway," where the shoulders, chest, arms, and hands move away from the ball together as a single unit for the first few feet. Many amateur golfers, however, incorrectly start the swing by immediately picking the club up with just their hands and wrists. This often involves rolling the wrists open, which almost guarantees the clubface will be open and the wrist will be cupped by the time you reach the top.
3. No Body Rotation
Another common fault is a lack of rotation. Instead of turning their torso, many golfers simply lift their arms straight up to get the club to the top. When the body doesn't turn, the arms and wrists have to perform some strange acrobatics to create length in the backswing. This arm-lift motion makes it far more likely for the wrist to fall back into a weak, cupped state.
Drills to Get a Flat Wrist and Purely Struck Shots
Alright, let's fix this. Moving from a cupped position to a flat wrist is all about feeling. You need to retrain your hands and body to understand this new, powerful position. The goal of these drills is to exaggerate the feeling so it becomes second nature.
Drill #1: The Motorcycle Feel
This is a an incredible drill for feeling the opposite of a cup.
- Take your normal setup.
- Make a slow-motion backswing until you reach the top.
- At the top, look at your left wrist. Now, intentionally make a motion as if you were revving the throttle on a motorcycle. The knuckles on your left hand should point more towards the ground.
- This action bows your wrist (flexes it), which is the complete opposite of cupping. Hold this "revved" position for a few seconds. Feel the pressure and the new position.
- Swing down slowly from there, trying to maintain that feeling.
Start without a ball, just making practice swings. Then, try hitting half-shots with an 8- or 9-iron while focusing solely on that motorcycle rev at the top. It will feel strange at first, but it's a dramatic way to teach your wrist what "flexion" means.
Drill #2: The Flat-Object Drill
This provides immediate tactile feedback.
- Grab a flat, rigid object like a a plastic ruler or even an old credit card.
- Tuck it under the back of your golf glove so it lays flat against the back of your wrist and forearm.
- Take slow swings. If you cup your wrist at the top, you will immediately feel the object digging uncomfortably into the top of your hand or wrist.
- Your goal is to make a backswing where you feel *no pressure* from the object. This means your wrist has stayed perfectly flat. It’s an undeniable form of feedback.
Drill #3: The Takeaway Gate
If your cupping is caused by a bad takeaway, this one's for you.
- Place a headcover or a spare golf ball about a foot directly behind your ball.
- Now, place another headcover or spare ball about a foot behind your club and slightly inside the target line.
- You have now created a "gate" for your club to travel through during the takeaway.
- Practice taking the club back without hitting either object. This forces you to move the club straight back initially with your shoulders and chest, not just rolling it open with your hands. A good takeaway sets up a good wrist position at the top.
Putting It All Together on the Range
Once you’ve ingrained the new feeling with these drills, it’s time to take it to the range. Don’t expect immediate perfection. Your brain and body need time to overwrite years of bad habits.
Start with a short iron, like a PW or 9-iron. Make slow, 50% swings focusing entirely on the feeling of a flat or slightly bowed wrist at the top. Don't worry about where the ball goes initially. It's all about feeling the position. You might even find that you start hitting some hooks. This is a GREAT sign! It means you're delivering a square or slighlty closed clubface - you just haven't learned to match it with your body rotation yet. Keep working on it, gradually increasing your swing speed as the new wrist action begins to feel more comfortable and automatic.
Final Thoughts
Transforming your wrist position from cupped to flat is one of the single most impactful changes a golfer can make for more power, accuracy, and consistency. By correcting your grip, improving your takeaway, and using targeted drills to create a new feel, you build a swing that doesn't rely on perfect timing to hit solid shots.
