How to swim butterfly is a skill that combines strength, technique, and rhythm. As a swimming blogger and expert, I’m here to guide you through mastering this elegant yet challenging stroke.
Whether you’re a beginner or looking to refine your technique, this guide will break down the essentials in a simple, approachable way. Let’s dive into the world of butterfly swimming together!
How To Swim Butterfly?
To swim butterfly, focus on your body movement first. I always start with a strong, rhythmic dolphin kick. Keep your legs together and move them in a fluid, wave-like motion.
Next, time your arm pulls perfectly. I pull my arms simultaneously in a circular motion, pushing the water back with power.
Remember to breathe forward, not sideways, as your arms recover over the water. Core strength is key—I engage my abs to maintain a steady flow.
Practice these steps slowly, and you’ll build the speed and coordination needed for this beautiful stroke.
Key Elements of Butterfly Stroke:
The butterfly stroke demands rhythm, power, and coordination. The key elements include a fluid body wave, where the chest leads a rolling motion through the torso. Strong arm movements involve a simultaneous pull and push, generating propulsion.
The dolphin kick, executed with both legs moving together, adds speed. Proper breathing technique—typically every second stroke—ensures efficiency without disrupting momentum.
Finally, timing is crucial, as syncing the arms, kick, and breath creates a smooth, energy-efficient stroke.
1. Powerful Catch and Pull
Apowerful catch and pull generate propulsion in the butterfly stroke. Both arms move simultaneously in a sweeping motion—outward, then inward—creating a strong forward drive. This phase is crucial for maintaining speed and efficiency in the water.
2. Efficient body undulation
Efficient body undulation ensures a smooth, wave-like movement. The chest leads the motion, allowing the hips to follow naturally. This technique reduces drag and helps conserve energy while maintaining fluidity.

3. Timed kick and stroke coordination
Timed kick and stroke coordination are essential for maintaining momentum. The dolphin kick, executed with both legs moving together, drives the body forward. Proper timing between the kick and arm movement ensures an efficient and continuous motion.
4. Synchronized arm recovery
Synchronized arm recovery plays a vital role in sustaining rhythm. Both arms must move together over the water, reducing resistance and preventing fatigue. A well-timed recovery phase allows for a smooth transition into the next stroke cycle.
Strong Catch and Powerful Arm Pull
A strong catch and powerful arm pull are essential for generating speed in the butterfly stroke. The stroke begins with both hands entering the water slightly wider than shoulder-width, followed by a high-elbow catch.
The arms then sweep outward and inward in a circular motion, pulling water forcefully toward the hips. This powerful pull propels the body forward, creating momentum and reducing drag.
A strong pull also sets the foundation for an efficient stroke, ensuring maximum propulsion with each cycle.
1. Fine-Tune Your Entry
A well-executed butterfly stroke begins with a precise hand entry. Your hands should enter the water slightly wider than shoulder-width, fingertips first, to minimize resistance.
Avoid a wide or overly deep entry, which can disrupt your stroke efficiency. A smooth, well-placed entry sets the stage for a powerful pull.
2. Position the Stroke
After entry, positioning your stroke correctly is crucial for maximum propulsion. Keep your elbows high as your hands move outward and slightly downward in the catch phase.
This positioning helps engage your back and shoulder muscles, allowing for a stronger pull through the water.
3. Drive Back Forcefully
A powerful pull drives the body forward. Once you reach the catch phase, sweep your arms inward and backward with force, pushing the water toward your hips.
This explosive movement generates speed and momentum, allowing for a smooth transition into the recovery phase.
Refine Your Undulation
Efficient body undulation is key to mastering the butterfly stroke. The movement starts from the chest, creating a wave-like motion that flows through the core and hips.
Avoid excessive bending at the waist—keep the motion fluid and controlled. A well-timed undulation helps reduce drag, conserve energy, and improve stroke efficiency.

Focus on maintaining a natural rhythm, allowing your body to rise for a breath without disrupting forward momentum.
1. Keep Low
Maintaining a low body position in the water reduces drag and increases efficiency. Avoid lifting your head too high when breathing, as this can cause your hips to sink.
Instead, keep your chin close to the water’s surface to stay streamlined.
2. Stay Near the Surface
Butterfly stroke thrives on smooth, surface-level swimming. Your undulation should be gentle and controlled, ensuring that your body stays just below the surface. Excessive up-and-down movement wastes energy and slows you down.
3. Adjust for Speed
Fine-tuning your undulation speed can enhance your performance. A faster tempo requires shorter, quicker undulations, while a longer stroke benefits from a more pronounced wave motion.
Adjusting your rhythm helps maintain momentum and efficiency throughout your swim.
Perfect Kick-Stroke Coordination
Achieving perfect kick-stroke coordination is vital for a smooth and powerful butterfly stroke. The dolphin kick should work in harmony with your arm movements.
As your hands begin their pull underwater, your legs should initiate a strong, upward kick, with both feet moving simultaneously in a fluid motion.
Timing is crucial—ensure your kick doesn’t lag behind your arms. The downward thrust of the kick provides propulsion, while the arm pull focuses on maintaining speed and momentum.
Proper coordination minimizes resistance and maximizes forward motion, creating a balanced, efficient stroke.
1. Kick Upfront
The first part of the dolphin kick starts with a strong, forward kick. As your body undulates, initiate the kick from the hips, not the knees.
The power should come from a quick upward motion, driving your body forward and helping you maintain your position near the water’s surface.
2. Kick at the Back
The backward part of the kick provides additional propulsion. As your legs move downward, your feet should point downward, creating resistance that pushes the body forward.
This phase contributes to building momentum and helping you glide smoothly through the water.
3. Snap the Kick
The snap of the kick occurs when the legs are rapidly brought together. This quick, forceful motion maximizes the power of the kick, adding a burst of speed just before you enter the next arm stroke.
Proper timing of this snap boosts your overall efficiency and helps you maintain rhythm.
4. Extend the Legs
After the snap, make sure to fully extend your legs before initiating the next undulation. Full leg extension allows you to streamline your body and reduces drag.
This also sets up the body for the next wave motion, ensuring your stroke remains fluid and powerful.
Sync Arm Recovery with Stroke
A smooth arm recovery is essential for maintaining momentum and rhythm in the butterfly stroke. As your arms complete the pull and move toward the surface, ensure they recover simultaneously.
The hands should glide over the water with minimal resistance, maintaining a relaxed yet controlled motion.

Timing is key—syncing the arm recovery with the next stroke ensures the body remains streamlined. As the arms move forward, the body undulation should follow in a natural, fluid motion.
This coordinated effort helps prevent fatigue and enhances efficiency, allowing you to maintain speed and consistency throughout the stroke cycle.
1. Swing Arms Smoothly
During the arm recovery phase, swing your arms smoothly and evenly over the water. Keep your elbows slightly bent and avoid overreaching. This relaxed, controlled motion allows your arms to glide effortlessly, minimizing resistance and preparing for the next pull.
2. Press the Chest Down
As your arms recover, press your chest down into the water. This helps keep your body position low and streamlined, preventing drag. By engaging your core and focusing on body undulation, you maintain momentum and a steady rhythm throughout the stroke.
3. Kick Forward
While your arms are recovering, kick forward with your legs. The timing of the dolphin kick should align with the arm recovery, ensuring that the momentum generated by the kick helps propel the body forward. This coordination maximizes speed and keeps your stroke fluid and powerful.
