Fix Your Pickleball Serve Forever: The 3 Mistakes Holding You Back
Gain consistent, effortless power on your serve by fixing these three critical mistakes seen at every level. APP pro Kyle Koszuta shows you how.
Kyle Koszuta just dropped a masterclass on what's actually sabotaging your serve. And honestly? Most of us are making at least one of these mistakes every single time we step on the court.
The serve is supposed to be your most controllable shot. You're not reacting to anything. You're not scrambling. You've got all the time in the world to set up, breathe, and execute.

Yet somehow, it's the shot that trips up players at every level.
Koszuta's latest video breaks down exactly why that happens, and more importantly, how to fix it.
1. You're Standing Too Narrow (And Losing All Your Power)
A narrow serve stance isn't just uncomfortable — it's actively working against you. When your feet are too close together, you lose stability and hurt your ability to transfer weight into the ball.
Koszuta recommends setting up with your front foot (left foot if you're right-handed) at about a 45-degree angle toward the baseline, while your back foot stays roughly parallel to the baseline. This creates what he calls a "power base." The wider your stance, the more stable you become, and the more you can shift your weight forward into the serve.
"You want to have an expectation that you might get pushed," Koszuta explains in the video. That's the sweet spot. Your feet should be wide enough that if someone gave you a gentle shove, you'd stay planted. Not so wide that you look ridiculous, but wide enough to matter.
Getting your pickleball posture right is the foundation everything else is built on — and it starts with your feet before the paddle ever moves.
2. You're Jamming Your Release (The T-Rex Serve Nobody Wants)
This one's almost funny until you realize you're probably doing it. Koszuta calls it the "T-Rex serve," and once you see it, you can't unsee it.
What happens is your elbow gets tucked too close to your body, and the ball ends up right on top of you. When you go to hit it, both your arms are compressed, and you're essentially swinging like a dinosaur with tiny arms. It looks ridiculous, and it performs even worse.
The fix? You need extension. Not just any extension, but the kind that forces you to reach for the ball.
Koszuta uses a golf analogy that's pretty perfect:
- When you're putting, the club is close to your body because you're not trying to hit it far.
- But when you're driving off the tee, you grab the longest club in your bag because that distance from your body allows you to accelerate the club head faster.
Same concept in pickleball. You want the ball positioned far enough away that you have to reach a bit to get it. This creates space, and space is what allows you to accelerate your paddle. Faster paddle speed equals harder, farther serves.
But here's where it gets interesting: it's not just about reaching away from your body. It's about getting the ball out in front of you.
"The more you go out and get it, the more you're going to generate topspin," Koszuta says. It's one of those things that sounds simple until you try it and realize how much it changes your serve.
This is especially important for players transitioning from tennis to pickleball — old arm-dominant muscle memory can absolutely tank your release mechanics before you ever recognize it.

3. You're Using Only Your Arm (And Leaving Power on the Table)
This is probably the most common mistake, especially among players who didn't grow up playing tennis. When we decide to hit something harder, our instinct is to swing faster with our arm. That's it. Just more arm.
But that's generating what Koszuta calls "effortful power," not "effortless power." And there's a massive difference.
Think of one of those wind-up toy cars. You wind up the wheels, release it, and there's this explosion of energy that sends it flying across the room. That's what you want your serve to feel like. Instead of just keeping your body still and swinging harder with your arm, you need to create a coil with your entire body.

Here's where rotational power comes in.
- When you set up in that wide power base we talked about earlier, and you extend the ball out in front, you've created the conditions for core rotation.
- Your paddle-side body rotates away from your target and then explosively rotates back toward it.
- Your right foot (if you're right-handed) should actually step into the court as you finish.
You can check yourself on this pretty easily. If you're hitting with pure arm swing, your back foot stays planted. Your body doesn't rotate. But when you're generating rotational power, your paddle-side body finishes toward your target, and your back foot comes off the ground.
"The power becomes exponentially greater by just adding core rotation," Koszuta explains. And he's right. Every other sport that requires power generation uses rotation. Golf, football, basketball. Why would pickleball be any different?
The same principle applies when you need to hit a heavy topspin drive — rotation isn't just for serves. It's the engine behind every power shot in your arsenal.
The bonus here? Rotation naturally generates topspin. You don't have to think about it. You don't have to manipulate your paddle face. Just focus on the contact point, and the rotation does the rest.
Pickleball's growth at the professional level has pushed technique analysis to a new level, with coaches and touring pros breaking down mechanics in ways recreational players can now directly apply to their own games.
The Bigger Picture: Why These Three Things Matter Together
What's clever about Koszuta's breakdown is that these three mistakes aren't isolated problems. They're interconnected.
- A narrow stance prevents rotation.
- A jammed release prevents extension.
- And without extension and rotation, you're stuck with arm power.
Fix all three, and your serve transforms. You're not just hitting harder. You're hitting with more control, more consistency, and more topspin. You're generating power that feels effortless because it actually is.
If you want to understand how your serve fits into the larger point construction picture, it's worth studying the first four shots in pickleball — a strong serve sets the table for everything that follows.
If you're serious about improving your serve, this is worth watching. And if you're already doing these things right? Well, you're probably already winning more matches than you used to.
Pickleball's surge in mainstream attention — covered extensively by NBC Sports — has meant more instructional content from touring pros than ever before, and it's never been a better time to sharpen the basics.
For players who want to take their full game to the next level, it also helps to understand the most important aspect of the pickleball serve beyond just mechanics — placement and intent matter just as much as technique.

Frequently Asked Questions
What is the most common pickleball serve mistake recreational players make?
The most common mistake is relying entirely on arm swing to generate power, which Koszuta calls "effortful power." Without core rotation and a wide stance, players cap their power potential and produce inconsistent serves. The fix is creating a full-body coil — wide base, extended release, and rotational finish.
How wide should my stance be when serving in pickleball?
Your stance should be wide enough that you feel balanced and grounded — think of an athletic ready position where you couldn't easily be pushed off your feet. Koszuta recommends your front foot angled about 45 degrees toward the baseline and your back foot roughly parallel to it. This "power base" is what allows you to shift your weight forward and generate momentum into the ball.
What does the "T-Rex serve" mean and how do I fix it?
The T-Rex serve happens when your elbow is tucked too close to your body, leaving both arms compressed at contact. The result is a weak, cramped swing with no room to accelerate your paddle. To fix it, extend the ball out far enough in front of you that you have to reach slightly — this creates the space needed for paddle speed and topspin.
Does core rotation really make a difference on a pickleball serve?
Yes — and it's not subtle. Core rotation is how every power sport generates force, from golf drives to baseball pitches. In pickleball, rotating your paddle-side shoulder away and then explosively back toward your target multiplies force far beyond what your arm alone can produce. A simple check: if your back foot never lifts off the ground during your serve, you're probably not rotating.
How do these three serve mistakes connect to each other?
They're a chain reaction. A narrow stance limits your ability to rotate. A jammed ball release limits your extension and paddle speed. And without both of those, you're forced to compensate with pure arm swing. Fix all three together — wide base, extended release, rotational finish — and the improvement is exponential, not incremental.
