The Best Butterfly Sculling Drills for Swimming: Build a Stronger Catch
What if your Butterfly didn’t feel exhausting — but controlled and connected?
Most swimmers are told Butterfly is about power. Kick harder. Pull stronger. Move faster. But here’s what I see on deck all the time: swimmers aren’t lacking strength — they’re lacking feel for the water. And if you don’t feel the water during your catch, your pull is just spinning your arms.
That’s where Butterfly sculling drills can become a game changer. There isn’t just one scull — there’s a whole collection of them, each targeting a specific part of your catch and pull so you can build real water feel from the ground up.
Why Butterfly Breaks Down So Easily
Butterfly is one of the most timing-dependent strokes in swimming. When something is off — even slightly — the whole stroke starts to fall apart. The most common issue isn’t the kick or the recovery. It’s the catch.
Swimmers enter the water, but instead of holding pressure, their hands slip. Their forearms don’t engage, and they lose connection before the pull even begins. From there, everything becomes forced. The kick gets bigger, the tempo increases, and the stroke feels heavier with every length.
(Mind-boggling, I know — but it’s incredibly common.)
The fix isn’t more effort. It’s learning how to hold water properly.
What Are Butterfly Sculling Drills?
Let me break it down.
Sculling is the overarching term — and there are a ton of variations. Each one targets a different part of your Butterfly Pull. What they all share is this: you slow down and focus on one stroke phase at a time.
Your hands move in small, controlled patterns — outward and inward — while staying in constant contact with the water. No rushing. No coasting. Just continuous pressure from your hands and forearms the entire time.
Here’s the way I explain it to my athletes: your hands are the paddles, your forearms are the anchors. When both are working together, you stop slipping through the water and start actually moving it.
That’s the difference between swimming Butterfly and owning it.
Start With Flow First (Before You Even Scull)
Before diving into sculling, there’s something important to understand. Butterfly only works when there’s rhythm between the kick and the pull. If your timing is off, even the best catch won’t fix your stroke.
One of my favorite ways to teach that rhythm is with a flow-based drill like this:
This drill reduces the number of arm strokes and emphasizes the importance of a consistent, well-timed kick. Swimmers start to feel how the body moves as one unit instead of separate parts. Once that rhythm is established, sculling becomes much more effective because the body is already working in sync.
Butterfly Sculling Drill for Beginners: Windshield Wiper Scull
This is where we start. Every swimmer — no matter what level — begins here.
Get flat on the surface, eyes down, and let a light kick keep your hips up. Now move your hands outward and inward in small, tight motions. Just like windshield wipers going back and forth across the glass.
Here’s what I tell my swimmers on deck: I don’t care how big the movement is. I care what you feel.
Your elbows stay bent. Your forearms stay on the water the whole time. If your hands are just waving around with zero resistance pushing back — stop. Slow it way down and find the pressure again. That pressure is the whole point.
This isn’t a conditioning drill. It’s a feel drill. Speed doesn’t matter here. What matters is that you’re learning to connect with the water on every single rep.
Do it right, and you’ll feel it immediately. Do it fast, and you’ll feel nothing — and learn nothing.
The Y Scull: Finding the Perfect Catch Position
Once swimmers understand how to feel pressure, the next step is learning where the catch should happen. The Y Scull Drill helps establish that position.
In this drill, the arms are placed slightly wider than the shoulders, forming a “Y” shape. From there, swimmers begin sculling inward while maintaining pressure on the water.
This teaches control at the edges of the pull, where many swimmers either go too wide and lose connection or too narrow and lose leverage.
The goal is to find the position where you can actually “grab” the water and direct it backward.
Building Pressure Awareness: Underwater Press Scull
The Underwater Press Scull takes things a step further by removing distractions and focusing entirely on feel. Swimmers push off the wall and do controlled sculling motions underwater. They notice how the water pushes back on their hands and forearms.
At some point, there’s a noticeable shift. The water stops slipping, and you feel the water the entire time — not just in one direction. That’s the moment when swimmers begin to truly understand how to hold water.
If you haven’t felt that yet, this is the drill to spend more time on.
Connecting It All Together: Football Scull
The Football Scull is where everything starts to connect to the full stroke. It follows the same basic hand movement as the windshield wiper scull, but it starts lower — with the hands working near and just under the hips instead of out in front.
From that position, swimmers scull through several controlled cycles. Then they time the end of the pull with the second kick. This helps the arms swing forward into recovery. That timing is the key — the second kick and the end of the pull happen together, which is exactly how Butterfly should feel.
One note on execution: resetting is a bit awkward, and that’s normal. There’s no need to dolphin kick between reps — simply return to the starting position and go again.
Why Many Swimmers Don’t Improve From Sculling
The biggest mistake is rushing.
Swimmers go through the motions without actually feeling the water. Their hands move, but there’s no pressure, no control, and no awareness. At that point, you’re just going through the motions instead of actually learning anything from the drill.
To get real value, you have to slow down and focus on what you feel — not just what you’re doing.
How Butterfly Sculling Drills Improve Performance
When sculling is done correctly, the impact on your Butterfly is immediate. The catch becomes stronger, the stroke feels smoother, and the overall effort decreases.
Instead of fighting the water, you start working with it.
That’s when Butterfly Starts to feel efficient — and even enjoyable.
What to Try in Your Next Practice
Start with short distances of sculling, focusing on control and pressure. Then transition into Butterfly swimming right after.
That shift—from drill to full stroke—is where the real improvement happens.
The “Feel for Water” Mini-Set
Try this at the start of your next main set to dial everything in:
4 × 25 @ :15 rest
- Odd: 15m Windshield Wiper Scull + 10m Butterfly
- Even: 15m Y Scull + 10m Butterfly
Focus:
Carry the same pressure from the scull into your stroke. If that feeling disappears once you start swimming, slow down and reset.
