Butterfly Drills for Beginners and Intermediate Swimmers

Overview

The most helpful way to approach butterfly technique is to stop thinking of it as a pure strength stroke. Good butterfly is built on rhythm and shape first, then power. If you try to muscle through the stroke before your timing is stable, you usually get the familiar results: a heavy recovery, dropped hips, breathes that stall momentum, and a second length that feels much harder than the first.

That is why the best butterfly drills are not just “harder fly sets.” They isolate one part of the stroke at a time: body undulation, kick timing, front-end catch, arm recovery, and breathing. When those pieces improve, butterfly becomes smoother and more repeatable.

For beginners, the goal is not a perfect full stroke over long distances. The first target is learning how the stroke should feel: chest presses forward, hips follow, kicks support the line of the body, and the arms recover without forcing the head high. For intermediate swimmers, the goal shifts from survival to efficiency. You want to hold form for more strokes, waste less energy on each breath, and keep the second kick connected to the finish of the pull.

Use this article as a hub. You can read it straight through once, then return to the sections that match your current problem. If your butterfly feels rushed, go to timing drills. If you are sinking on the breath, go to body line and breathing drills. If your recovery feels heavy, revisit single-arm and 3-3-3 progressions.

A useful rule for any swimmer working on butterfly for beginners or intermediates: stop the repetition when the drill no longer teaches the right movement. Butterfly punishes low-quality volume. Short, focused repeats almost always help more than grinding through bad form.

Topic map

Think of butterfly technique as five connected skills. Each skill has drills that fit best at different stages of learning.

1. Body line and undulation

This is the foundation. Butterfly is not a flat, rigid stroke, but it also should not become a dramatic dolphin wave. The movement is subtle and travels forward. Your chest presses slightly, your hips respond, and the kick supports that motion.

• Push-off to dolphin kick on front: Streamline off the wall, face down, and do relaxed dolphin kicks while keeping the head neutral. Focus on pressing the chest slightly rather than bending hard at the knees.
• Body dolphin with arms at sides: Swim butterfly motion without arm pulls. This teaches the line of the body and helps beginners feel where the movement starts.
• Body dolphin with fins: Fins can help you maintain momentum and feel the timing without fighting to stay on top of the water.

Best for: swimmers who feel stuck, flat, or out of sync before the arms even start.

2. Kick timing

Most swimmers have heard that butterfly uses two kicks per stroke cycle, but knowing that in theory is different from feeling it in motion. A simple way to frame it is this: one kick supports the entry and extension in front, and the second kick supports the finish of the pull and drives the recovery.

• Vertical dolphin kick: In deep water, hands across chest or streamlined overhead if strong enough. Keep kicks compact and rhythmic. This improves kick shape and exposes excessive knee bend.
• Single-pull butterfly: Several dolphin kicks with one full arm stroke, then reset. This slows the cycle down so you can feel when the kicks should happen.
• Kick-pull-pause drill: One stroke cycle, pause in a long line, then repeat. This helps connect the second kick to the finish without rushing into the next pull.

Best for: swimmers whose legs trail behind the stroke or whose recovery feels unsupported.

3. Catch and front-end pressure

Butterfly does not improve when the hands slap forward and immediately push down. The arms need to enter cleanly, extend into the line of travel, and set a catch that moves water backward, not downward.

• Single-arm butterfly: One arm strokes while the other stays forward. Breathe to the stroking side or keep the face down if possible. This is one of the best butterfly drills for learning front-end timing.
• Double-arm pull with board or snorkel support: If available, use a front snorkel to remove breathing pressure and focus on the catch.
• Scull to butterfly pull: A few front sculls, then one controlled butterfly stroke. This sharpens awareness of forearm pressure in the catch.

Best for: swimmers who feel like they are slipping through the water instead of holding it.

4. Recovery and relaxation

One reason butterfly feels exhausting is that many swimmers carry too much tension through the over-water recovery. The arms should recover with width and softness, not with shrugged shoulders and a forced heave.

• Right arm only, left arm only: Single-arm work keeps the recovery manageable and highlights asymmetries.
• 3-3-3 drill: Three right-arm strokes, three left-arm strokes, three full butterfly strokes. This is a classic bridge from isolated work to full coordination.
• Butterfly with fins, no breath: Swim very short repeats with no breath to feel an easy, low recovery and uninterrupted body line.

Best for: swimmers who feel tight across the shoulders or throw the arms out of the water with effort.

5. Breathing and whole-stroke timing

Breathing is where many butterfly strokes collapse. The problem is usually not the breath itself but when and how it happens. If the head lifts too early or stays up too long, the hips drop and the next stroke gets heavy.

• One-breath butterfly: Breathe every other stroke for short repeats. This can help swimmers feel a lower head position and cleaner line.
• Two kicks, one pull, one breath: Performed slowly to reinforce sequencing.
• 2-2-2 drill: Two strokes no breath, two strokes with breath, two strokes no breath. This teaches you to separate good line from urgent breathing.

Best for: swimmers who can do butterfly but lose shape every time they lift to breathe.

Related subtopics

Butterfly improves faster when you understand the nearby skills that support it. These are the subtopics most worth revisiting alongside your drill work.

Body position across all strokes

Butterfly exaggerates any weakness in alignment. If your core control is inconsistent, your hips will not stay close to the surface and every stroke gets more expensive. Even if butterfly is your immediate focus, it is useful to compare your posture with other strokes. Our Backstroke Technique Checklist: Body Position, Rotation, Kick, and Pull and Freestyle Drills That Fix Sinking Legs, Crossover, and Poor Catch both reinforce line, balance, and catch awareness.

Timing over force

Many swimmers ask how to improve butterfly by getting stronger. Strength helps, but timing produces the bigger immediate gain for most beginners and intermediates. Butterfly is a coordination stroke first. The same lesson shows up in breaststroke, where sequence matters more than raw effort. If timing is your weak point, Breaststroke Timing Guide: How to Coordinate Pull, Breath, Kick, and Glide is a useful companion read.

How much butterfly to include in a session

Because fly is demanding, it is easy to overdo it. A smart butterfly session usually has short, technical repeats early in the workout when you are fresh. Then you can add controlled whole-stroke work or mixed IM-style sets if your form holds. If you need a broader structure for your week, see Weekly Swim Training Plan for 1, 2, 3, and 4 Days per Week. If you are newer to structured swimming, Best Swim Workouts for Beginners by Goal can help you place butterfly work without letting it dominate the whole session.

Distance expectations

One hidden frustration with butterfly for beginners is comparing fly distance to freestyle distance. You may be comfortable swimming long freestyle repeats and still only manage short butterfly repeats with good form. That is normal. In butterfly, the question is less “How far can I go?” and more “How many quality strokes can I hold?” If you are planning total volume in a session, it can help to understand pool distances clearly using How Many Laps Is a Mile in a Pool? Full Distance Conversion Guide.

Recovery and shoulder management

Butterfly adds load to the shoulders, upper back, and trunk. Drill quality tends to drop quickly when you are fatigued or tight. For that reason, technique work and recovery belong together. If heavy fly sessions leave you feeling beat up, it is worth building a simple recovery routine after practice and between hard days. For a broader look at what good support can include, see Recovery Services Swimmers Should Expect: Lessons from Award-Winning Wellness Centers.

Tracking your progress

Butterfly progress is often easier to see than to feel. Video, stroke counts, and notes on where the stroke breaks down can all help. Some swimmers like to use simple digital tools or training logs to compare drill work over time. If that interests you, Using AI for Swimmer Progress Tracking: Accuracy, Ethics, and Coach Oversight offers a useful frame for keeping technology practical rather than distracting.

How to use this hub

The best way to use this article is not to try every butterfly drill in one session. Pick the problem that shows up most often in your stroke, then choose one or two drills that address it.

If you are a true beginner

Start with body dolphin, front dolphin kick, and single-pull progressions. Your first objective is rhythm, not distance. A good beginner butterfly set might be 6 to 8 x 25 with plenty of rest, mixing one drill and one easy whole-stroke attempt. Example:

• 25 body dolphin with fins
• 25 single-arm right
• 25 single-arm left
• 25 butterfly swim, 3 to 5 quality strokes then easy freestyle to the wall

Repeat that round once or twice. Stop while you can still keep the shape of the stroke.

If you are an intermediate swimmer

Move toward combinations that bridge drill work into full swim: 3-3-3 drill, one-breath butterfly, and short repeats of controlled whole stroke. A useful format is drill-swim pairing. Example:

• 4 x 25 single-arm butterfly by 25
• 4 x 25 3-3-3 drill by 25
• 4 x 25 butterfly swim, aiming for even rhythm and low breath

Take enough rest to preserve quality. Butterfly rarely rewards rushed intervals when the goal is technical improvement.

What to look for in the water

Use a short checklist instead of overthinking every cue at once:

• Head returns down quickly after the breath
• Chest presses forward, not straight down
• Second kick helps finish the stroke and lighten the recovery
• Hands enter cleanly without overreaching or slapping
• Recovery stays wide and relaxed

If more than one item is breaking down, return to the earliest drill in the chain rather than pushing through full stroke.

How often to practice butterfly drills

For most swimmers, two focused butterfly touches per week is enough to improve without accumulating poor habits. Even 10 to 15 minutes of high-quality drill work can move the stroke forward. More advanced swimmers may include fly more often, but the principle stays the same: quality first, volume second.

Which equipment can help

Fins are often the most useful tool because they support body line and rhythm. A front snorkel can also help by removing the disruption of breathing while you learn catch timing and line. Use tools to clarify the movement, not to hide flaws. If you can only do a drill with a lot of equipment and the feeling disappears without it, scale the task down.

When to revisit

Come back to this hub whenever your butterfly changes stage or develops a clear new weakness. In practice, that usually means revisiting it in five situations:

• When you can survive a 25 but not repeat it well: shift from basic body line drills to timing and recovery drills.
• When breathing disrupts the stroke: revisit one-breath, 2-2-2, and low-head timing work.
• When your arms feel heavy late in a set: return to single-arm and kick-supported drills to reconnect the second kick.
• When you start swimming longer fly repeats: review efficiency cues, not just endurance.
• When a coach video or self-review shows a new pattern: choose the drill that matches the actual error instead of repeating favorite drills by habit.

A simple action plan is to reassess your butterfly every four to six weeks. Ask three questions: Where does the stroke break first? What cue has helped most recently? Which drill still transfers cleanly into full swim? Then build your next short block around those answers.

If you train multiple strokes, keep your technique work connected. Butterfly often improves alongside better breathing control, cleaner body alignment, and stronger timing awareness in freestyle, backstroke, and breaststroke. That makes this hub worth revisiting not only when your fly changes, but also when your overall swimming changes.

For now, keep it simple: choose one problem, one drill, one cue, and one short set. Butterfly gets better when you make it repeatable before you make it hard.
