Nothing kills the confidence from a perfect practice swing like the dull thud of a fat golf shot that barely dribbles forward. Taking a divot the size of a dinner plate behind the ball is frustrating, to say the least, but it’s one of the most common issues golfers face - and thankfully, one of the most fixable. This tutorial will break down exactly why you hit fat shots and give you practical, step-by-step drills to train your body to make that pure, ball-first contact you’re looking for.
Understanding the "Fat" Shot: Why It Really Happens
Hitting a shot “fat,” “heavy,” or “chunked” comes down to one simple biomechanical flaw: the low point of your golf swing arc is happening behind the golf ball instead of slightly in front of it. An ideal iron shot makes contact with the ball first and then takes a shallow divot on the target side of where the ball was. When you hit it fat, your club hits the ground first, digging into the turf and losing the vast majority of its speed and energy before it ever gets to the ball. The result is a weak shot that travels just a fraction of its intended distance.
But what’s causing your low point to bottom out in the wrong place? While factors like a faulty setup can contribute, the problem almost always boils down to two key culprits during the downswing:
- Poor Weight Shift: This is the number one offender. Golfers who hit fat shots almost always fail to move their weight properly from their trail foot to their lead foot during the downswing. They hang back, keep their weight on their back leg, and try to scoop or lift the ball into the air. When your weight stays back, the bottom of your swing arc naturally stays back with it, leading to a fat shot.
- Casting the Club: This is an early release of the angles you create with your wrists at the top of your backswing. Instead of your body leading the downswing and pulling the hands and club through impact, you instinctively “throw” the clubhead at the ball with your hands and arms. This forces the club to extend too early, reaching its low point long before it ever gets to the ball.
The great news is that both of these are habits, and habits can be replaced. Let’s get to work on ingraining the right feelings and movements so you can leave fat shots in the past.
The Cure, Part 1: Master Your Low Point with a Proper Weight Shift
The absolute foundation of a pure iron strike is getting your weight to shift forward through the shot. When your weight moves forward correctly, it automatically moves the low point of your swing forward, allowing you to hit the ball first and then the ground. The mental image should be hitting down on the ball, with the ground contact happening on the target side.
Instead of thinking about a dozen complicated swing thoughts, focus on a single feeling: your chest and belt buckle should finish facing the target. If you can achieve that, you absolutely have to shift your weight forward. Let’s train that feeling with a couple of incredibly effective drills.
Drill #1: The Line Drill (The Ultimate Feedback Tool)
This is arguably the most famous and effective drill for curing fat shots because the feedback is instantaneous and impossible to ignore. It forces you to get your low point in the right spot.
- At the course: On the driving range tee or a practice area, simply draw a straight line in the grass with a tee or the edge of your club. This line will represent your ball position.
- At a mat-only range: Lay a towel or a headcover down about 6-8 inches behind your golf ball. Your goal is to miss the towel completely on your downswing.
- The Goal: Set up so the line (or your ball) is in the middle of your stance. Take some practice swings with the simple goal of making your divot start on or after the line. If your divot starts behind the line, you know your weight stayed back.
- How It Works: To consistently make your divot on the target side of the line, your body has no choice but to shift its weight forward. You’ll begin to feel your weight move into your lead leg and see that coveted, shallow divot appear in front of the line. Start with small, half-swings, focusing only on the divot location. Once you can do it consistently, place a ball on the line and repeat. The sound and feel of a purely struck shot will be your reward.
Drill #2: The Step-Through Drill
This drill actively prevents you from hanging back on your trail foot by forcing you to move through the shot in a dynamic, athletic-feeling way. It’s fantastic for golfers who feel locked on their back foot.
- Set Up: Take your normal stance and address the ball. Begin your backswing as you normally would.
- The Move: As you swing down and through impact, allow your trail foot (your right foot for a right-handed golfer) to naturally come off the ground and take a step forward towards the target, finishing in a balanced "walking" position. You should finish with all of your weight on your lead foot, with your trail foot having stepped past where the ball was.
- Why It Works: It is physically impossible to hang back and execute this drill correctly. By forcing yourself to step forward, you are training your body to complete the weight transfer and finish a balanced swing facing your target. It encourages a full-body rotation and a confident, powerful finish. Start without a ball, groove the motion, and then try hitting shots with it.
The Cure, Part 2: Tame the "Cast" and Maintain Your Swing Angles
If you've mastered your weight shift but still hit an occasional shot heavy, the culprit is likely "casting," or throwing the club from the top. Many golfers do this subconsciously, thinking it will generate more power, but it does in fact the opposite. Real power and clean contact come from lag - the feeling of the clubhead “trailing” your hands on the way down, created by maintaining the angle in your wrists.
Drill #3: The Pump Drill
This drill helps you feel what it’s like to store energy and release it at the right time - through the ball - rather than wasting it at the start of your downswing.
- Get to the Top: Take a normal-paced backswing to the top.
- The Pumps: Begin your downswing slowly, but stop when your hands get down to about waist height. From here is the "pump." Without going back up to the top, smoothly bring your hands and the club back up slightly, then back down to that waist-high position. Your focus should be on keeping that angle in your trail wrist, feeling like you are pulling the handle of the club down, not throwing the clubhead. Do this two or three times - pumping motion Down -> Up -> Down.
- Hit the Ball: After the final "pump," continue the motion down from waist-high into a full swing through impact and to your finish.
- What It Feels Like: You’ll notice an immense feeling of stored energy. This drill forces you to keep your wrist angles intact further into the downswing, delivering the clubhead with speed exactly where it counts – at the bottom of the swing. This sequence promotes that ball-first strike and eliminates the cast move.
The Cure, Part 3: Check Your Setup For Success
Sometimes, you can be predisposed to hitting a fat shot before you even start your swing. An improper setup can make a good weight shift or a proper release very difficult to achieve. Here are two quick checkpoints.
Is Your Ball Position Correct?
For mid-irons (like a 7, 8, or 9-iron), the ball should be positioned in the very center of your stance, directly underneath the buttons on your shirt. A ball position that is too far forward in your stance for an iron shot forces your swing to bottom out early, behind the ball. Moving it even one inch back toward the center can make a significant difference. Your longest irons and hybrids can move slightly forward of center, but not by much.
Is Your Posture Balanced?
A common fault is tilting your spine too far away from the target at address. While a slight tilt is natural, too much will pre-load your weight onto your back foot, making a proper forward shift much harder to achieve. Feel like your weight is distributed 50/50 between your feet at address. Your upper body should be tilted forward from your hips, but your spine shouldn't be leaning dramatically away from the target. An athletic, centered posture is your foundation for a powerful and consistent swing.
Final Thoughts
Stopping fat shots comes down to controlling the low point of your swing, which is achieved by getting your weight forward and maintaining your wrist angles during the downswing. By focusing on that feeling of "ball, then turf" and using the line drill, step-through drill, and pump drill, you can retrain your habits and start compressing the ball for consistently pure strikes.
