Butterfly stroke is one of the most powerful yet technically challenging techniques in competitive swimming. Known for its explosive speed and graceful rhythm, butterfly requires precise coordination between arm movements, kicks, and core muscles.
Mastering the fundamentals is essential for swimmers at every level, not only to improve performance, but also to swim efficiently and avoid fatigue and injury. This guide will break down each step clearly, helping you build confidence, control, and flow in the water.
8 Simple Steps to Swim Butterfly Stroke
Butterfly stroke relies on a combination of strength, rhythm, and precise timing. This section provides a clear step-by-step guide, from the push-off to maintaining a consistent, smooth rhythm.
Each step builds a strong foundation for an effective butterfly stroke:
1. Start With a Strong Push-Off
A strong initial push is essential to create momentum in butterfly stroke. Push off from the wall with both feet, extend your arms straight above your head, and keep your body in a streamlined position. Your head should be between your arms, with your gaze down to maintain alignment.
Keep your fingers close together and straight to minimise water resistance. Your body should be elongated and straight, with your core engaged to maintain a rigid shape. The goal is to create as little friction as possible while gliding.
This initial glide gives you time to settle your breathing and prepare mentally for the next stroke cycle.
2. Begin the Body Wave Motion (Undulation)
Body undulation is the hallmark of butterfly stroke, creating a wave-like motion that propels you forward.
Start by pressing your chest slightly downward, letting the movement flow through your hips and finish at your feet. This motion should flow smoothly, like a wave travelling along your body.
Focus on starting from the chest, not the knees, so as not to disrupt the rhythm and create drag. The hips will naturally follow the chest's movement, creating a balanced flow.
3. Perform the Dolphin Kick
The dolphin kick is the main source of propulsion in butterfly stroke. It is performed twice within one stroke cycle, once while pulling the arms underwater, and again as the arms return forward.
The first kick helps lift the upper body, while the second kick maintains momentum.
Keep your legs straight and together, point your toes, and start the motion from your hips, not your knees. Core engagement is essential to control this movement.
Train the strength and flexibility of your hips, lower back, and core with vertical kicking drills and the use of fins to build endurance.
4. Begin the Arm Pull (Catch Phase)
The initial pull begins once your hands enter the water at shoulder width. Angle your palms outward and downward, with your elbows high and your fingers pointing diagonally downward.
Form a shallow “Y” shape as you pull to direct the propulsion backward, not downward. This allows your body to move forward through the water efficiently.
This stage is crucial as it forms the basis of forward movement and determines the success of the following push.
5. Pull Inward and Push Backward (Pull and Exit Phase)
After the catch phase, pull your hands toward your chest with a strong and controlled motion. Keep your elbows high and lead with your forearms to catch more water.
Continue by pushing your hands straight backward until they are close to your hips. Do not push too far back, as this can disrupt your rhythm and waste energy.
Focus on a compact and efficient movement to maintain speed and avoid excessive fatigue.
6. Return the Arms Above the Water
The recovery motion involves lifting both arms out of the water and swinging them forward simultaneously. Move your arms in a smooth arc, low enough to avoid resistance.
Keep your shoulders relaxed and your elbows slightly bent so the movement feels natural. Avoid tension that could cause injury or make the movement feel heavy.
Perform this motion close to the water's surface to conserve energy and maintain stroke balance.
7. Time Your Breathing Correctly
Take a breath as your arms finish pulling, just before entering the recovery phase. Lift your head and shoulders slightly, keeping your chin close to the water's surface to reduce drag.
Exhale slowly underwater to keep your breathing steady and unhurried. Practise your breathing with drills such as one-arm butterfly or body dolphin, focusing on the timing of your breath.
8. Maintain Rhythm and Flow of Movement
Efficient butterfly stroke depends on synchronising your arm movements, kicks, and breathing. Each element must complement the others to create a wave-like motion that continually propels you forward.
Consistency is key. Focus on rhythm and coordination rather than strength alone.
Butterfly Stroke Technique Tips to Improve Your Swimming Ability
- One-Arm Butterfly Drill: Builds strength and balance while improving the catch and recovery phases.
- Body Dolphin Drill: Helps perfect the body's wave-like movement.
- Use Fins: Adds propulsion and strengthens the kick.
- Dryland Training: Focuses on strengthening the core and shoulder muscles.
- Rhythmic and Relaxed Breathing: Avoid rushing and keep your breathing flow steady so your stroke stays smooth.
- Visualise Your Body as a Wave: Helps maintain rhythm and fluidity of movement.
5 Common Mistakes in Butterfly Stroke Technique (And How to Fix Them)
Relying Too Much on the Arms
Solution: Focus on overall body coordination, practise body undulation.
Incorrect Breathing Timing
Solution: Keep your chin low when inhaling, and exhale steadily underwater.
Weak Dolphin Kick Technique
Solution: Practise vertical kicking and use fins, keep your legs straight and together.
Body Position Too Flat
Solution: Use the body dolphin drill to get used to the natural up-and-down movement.
Too Much Splashing and Drag
Solution: Improve your arm recovery phase, keep the movement low and controlled.
Conclusion
Mastering the butterfly stroke is not just about strength, but about precision, rhythm, and understanding every part of it. Focusing on the basics such as body undulation and breathing timing will bring you smoother, stronger technique.
Regular practice and patience will bring results. Over time, you will feel more confident and enjoy swimming the butterfly stroke.

Frequently asked questions
Does the butterfly stroke burn more calories than other strokes?
Yes, because it engages many large muscle groups and requires high intensity.
Are there variations of the butterfly stroke?
There are small adjustments depending on the swimmer's body shape, such as a wider arm pull or a different kick rhythm.
Can children learn the butterfly stroke from an early age?
Yes, generally from around 6 to 7 years old after mastering freestyle and backstroke.
When should the butterfly stroke be added to training?
After having a strong foundation in swimming technique and good physical condition.
Should you focus on speed or technique first?
Focus on technique first to avoid injury and fatigue.
