Using fins while practicing the butterfly stroke is an effective way to build leg strength, improve kick timing, and enhance power in the water. Fins provide added propulsion, allowing swimmers to focus on their body undulation and kick rhythm without straining too much. Training with fins also helps swimmers achieve better body alignment, making it easier to develop a powerful dolphin kick that’s essential for a smooth, efficient butterfly stroke.
In this post, we’ll explore the benefits of using fins for butterfly training and cover targeted drills to help you develop stronger, more effective kick power in butterfly. Let’s dive into some fin-focused drills that will transform your butterfly technique!
Benefits of Using Fins for Butterfly Kick Development
Incorporating fins into butterfly training provides multiple advantages for swimmers aiming to improve kick power and overall efficiency:
Increases Kick Power: The resistance created by fins engages the leg muscles more intensively, building strength and endurance in the calves, quads, hamstrings, and glutes.
Improves Kick Timing and Rhythm: Fins enable swimmers to practice the butterfly kick at higher speeds, helping them develop a consistent kick rhythm and better sync between the upper and lower body.
Enhances Body Position and Alignment: Using fins keeps the body in a more streamlined position, encouraging better body alignment and core engagement.
Builds Core Strength: The butterfly kick engages core muscles, and fins make this engagement more intense, helping develop the core stability required for an efficient butterfly stroke.
Key Aspects of a Powerful Butterfly Kick
To maximize the benefits of fins in butterfly training, swimmers need to focus on a few key elements of the kick:
Body Undulation: A smooth body wave motion, initiated from the chest and flowing down to the hips, is essential for efficient butterfly.
Two-Beat Kick Rhythm: Butterfly involves two kicks per arm stroke cycle: one as the hands enter the water and a second, stronger kick during the pull.
Core Engagement: Engaging the core throughout the kick stabilizes the body, reduces drag, and helps transfer power from the legs to the rest of the body.
Kick Power: Each kick should be controlled and powerful, propelling the body forward rather than causing excessive vertical movement.
Butterfly with Fins Drills for Developing Kick Power
The following drills are designed to maximize the benefits of fins, helping swimmers strengthen their legs, improve kick timing, and achieve a powerful, synchronized butterfly kick.
Drill 1: Vertical Dolphin Kick with Fins

How to Do It:
Stand vertically in the deep end of the pool with fins on, keeping your head above the water.
Perform continuous dolphin kicks, using your core and legs to stay afloat.
Focus Points:
Keep your hands at your sides or cross them over your chest to isolate the kick.
Focus on kicking from the hips, engaging your core to maintain stability.
Repetitions: Perform 3–5 sets of 20–30 seconds, resting between sets.
Drill 2: Streamlined Dolphin Kick with Fins
Purpose: This drill enhances body alignment, core strength, and streamline, allowing you to focus on a powerful, narrow dolphin kick.
How to Do It:
Push off from the wall in a streamlined position with arms extended above your head.
Use a consistent dolphin kick, aiming to keep your body as streamlined as possible.
Focus Points:
Engage your core to keep your body aligned, with minimal vertical movement.
Maintain a steady, controlled kick rhythm, focusing on power rather than speed.
Repetitions: Swim 4–6 laps with streamlined dolphin kick, aiming to glide smoothly through the water.
Drill 3: Body Wave Drill with Fins
Purpose: This drill focuses on developing a smooth body undulation, essential for a rhythmic butterfly stroke.
How to Do It:
Begin face down in the water with your arms at your sides and fins on.
Perform a gentle dolphin kick, starting the wave motion from your chest and letting it flow down through your body to your legs.
Focus Points:
Concentrate on a relaxed, continuous wave-like motion to avoid excessive vertical movement.
Use your fins to guide the movement, feeling how each undulation creates forward momentum.
Repetitions: Perform 4–6 laps, focusing on maintaining a steady, wave-like rhythm.
Drill 4: 3-3-3 Drill (Butterfly with Fins)
Purpose: The 3-3-3 drill isolates the kick and the pull, helping swimmers coordinate timing and rhythm with added fin support.
How to Do It:
Start by doing three dolphin kicks in streamline without using your arms.
Follow with three full butterfly strokes, focusing on kick timing.
Finish with three strokes using only the arms.
Focus Points:
Emphasize a strong, controlled kick during the initial 3-kick phase.
Maintain a steady two-beat kick rhythm during the full stroke portion.
Repetitions: Perform 4–6 rounds of the 3-3-3 drill, focusing on a consistent kick rhythm.
Drill 5: Underwater Dolphin Kick with Fins
Purpose: This drill develops a powerful underwater kick, enhancing overall kick strength and body control.
How to Do It:
Push off from the wall and perform dolphin kicks underwater with fins, keeping your arms in streamline.
Aim to stay underwater for as long as possible while maintaining a powerful, steady kick.
Focus Points:
Engage your core and keep your body in a streamlined position to minimize drag.
Use the fins to feel the resistance and power in each kick.
Repetitions: Swim 4–6 laps with underwater dolphin kick, surfacing only when necessary.
Drill 6: Full-Stroke Butterfly with Fins
Purpose: Swimming full-stroke butterfly with fins reinforces proper body alignment and kick rhythm while providing extra speed and power.
How to Do It:
Swim butterfly with fins, focusing on the two-beat kick rhythm and body undulation.
Use the fins to enhance the power of each kick, aiming to sync the kicks with arm strokes.
Focus Points:
Emphasize a strong kick as the hands enter the water and a second, more powerful kick during the pull.
Maintain fluid body undulation, using the fins to feel the kick’s impact on your forward motion.
Repetitions: Swim 4–6 laps, focusing on timing, rhythm, and a strong kick in sync with each stroke.
Common Mistakes When Using Fins in Butterfly and How to Fix Them
Even with fins, swimmers may encounter challenges in developing a smooth, powerful butterfly kick. Here are some common mistakes and ways to fix them:
Kicking from the Knees: Kicking primarily from the knees rather than the hips reduces power and disrupts body alignment.
Solution: Practice the Streamlined Dolphin Kick with Fins to focus on kicking from the hips and engaging the core.
Overkicking: Excessive vertical movement due to overkicking can disrupt body position and increase drag.
Solution: Perform the Body Wave Drill with Fins, focusing on smooth, controlled undulations rather than large, forceful kicks.
Timing Errors: Incorrect kick timing can result in inefficient strokes and lost momentum.
Solution: Use the 3-3-3 Drill to isolate and focus on kick timing, ensuring a strong kick as the hands enter the water and another kick during the pull.
Relying Too Much on Fins: Relying too heavily on fins can lead to poor technique when fins are removed.
Solution: Alternate between using fins and swimming without them to ensure proper kick technique and strength transfer without fins.
Tips for Effective Butterfly Training with Fins
To get the most out of butterfly training with fins, keep these tips in mind:
Choose the Right Fins: Short-blade fins are ideal for butterfly training, as they provide propulsion without sacrificing technique and allow for a faster kick rhythm.
Focus on Technique Over Speed: Although fins increase speed, the primary focus should remain on developing proper kick technique, rhythm, and core engagement.
Alternate Fin and Non-Fin Training: Mixing fin and non-fin training allows you to transfer the strength, timing, and technique you gain from fins into your unassisted butterfly stroke.
Stay Relaxed and Fluid: Tension can disrupt the smooth wave-like motion of butterfly. Focus on staying relaxed, especially in the shoulders and hips, to maintain fluid body undulation.
Increase Gradually: Begin with short sets when incorporating fins into your butterfly training and gradually increase intensity and duration to prevent overuse or strain.
