Butterfly Technique for Beginners: Rhythm Over Muscle

Written by Candice Darr · Approved by Melanie Margalis Fink · Updated Aug 18, 2026 · 8 min read

New butterfly swimmers, once they watch a highlight reel of an elite swimmer’s shoulders exploding out of the water, decide the stroke is about upper-body strength. It really isn’t – or at least, not mostly. Instead, it’s a timing problem wearing a strength costume.

Swimmers who figure that out in their first month swim it far more comfortably than the ones who spend a whole season muscling through it.

This guide is written to your swimmer directly, in language they can use at the next practice, and built for you to read alongside them.

You don’t need to coach the stroke, just know that butterfly rewards rhythm over raw power so it makes sense when your swimmer talks about it on the drive home.

Swimmer, the rest of this is for you.

Butterfly body position: fighting the natural rise and fall

Butterfly’s body-position problem is built into the stroke itself. U.S. Masters Swimming’s butterfly guide explains that as you pull, your upper body rises and your hips sink, and then during arm recovery, your body tilts at an angle that adds drag.

You can’t erase either tendency completely, but you can counter both with well-timed kicks. A hard kick as your pull finishes lifts your hips back up right when they’d otherwise drop. A hard kick as your hands re-enter the water levels your body back out after the incline of recovery. Get that timing right and the stroke starts to feel less like a fight and more like a rhythm.

A useful visual cue comes from SwimSwam’s butterfly technique guide, where longtime Michael Phelps coach Bob Bowman describes the target as a “dry back,” meaning a large portion of your back stays visible at the surface throughout the stroke. A wet, submerged back usually means you’re undulating too deep and adding drag you don’t need.

The dolphin kick: the engine most beginners underuse

Your legs kick simultaneously twice per stroke cycle in butterfly. An effective kick presses the flat surfaces of your feet backward against the water rather than just splashing up and down. The down-kick draws on your hip flexors and quads, while the up-kick relies on your hamstrings and glutes to reset quickly for the next one.

For years, young swimmers were taught a big-kick, small-kick pattern – one dominant downbeat and one lighter one. That thinking has shifted. Modern coaching treats both kicks in the cycle as roughly equal in size and intensity, with the knees bending toward 90 degrees before the propulsive downbeat.

The rhythm to aim for is continuous and evenly timed, closer to jumping rope than one big stomp followed by an afterthought.

The one kick rule that gets beginners disqualified

In high school and club competition, both USA Swimming and the NFHS (which govern high school racing) require the butterfly kick to be an up-and-down movement of both legs together, They specifically list scissors, flutter, and breaststroke-style kicks as disqualifying faults.

So for a high school swimmer, the dolphin kick isn’t just the better choice, it’s the only legal one. Even a small flutter kick will disqualify you.

If your kick feels strong but your stroke still stalls out by 15 yards, look at your kick timing before you assume you need more conditioning. A kick that lands at the wrong moment in your pull cycle burns just as much energy as a well-timed one, while doing almost nothing to keep your hips up.

Butterfly pull: one motion, both arms, no shortcuts

During each cycle, your arms pull simultaneously once and recover simultaneously once. The goal is pushing backward against the water with your hands and forearms facing back through the entire pull, as fast and as long as possible. Your pectorals and lats generate most of the power, with your triceps kicking in at the very end to finish the push and get your hands moving fast enough for recovery. *

Rather than the more bent-arm style that was common decades ago, today’s swimmers use a straight-arm recovery. Straight arms bring your hands around just above the surface without the extra shoulder rotation and undulation a bent-arm recovery tends to create. The result is a cleaner, flatter body line.

Pull width and depth vary between swimmers based on strength and shoulder mobility, so don’t force your pull into a shape that fights your own range of motion. Speed up through the pull, then move your arms over the water quickly once they exit.

Butterfly breathing: timing beats effort

Breathing patterns in butterfly range widely. USMS notes that some swimmers breathe every stroke, some every other, some every third, and some use a pattern of two breathing strokes followed by one without.

As a general rule, the shorter the race, the less a swimmer breathes. The timing cue that helps beginners most is to connect your breath to the moment your hands pass under your chest during the pull. Lift your head for the breath right there, then tuck it back into a streamlined position immediately.

Breathe too early and your hips will sink while your momentum stalls, which will turn a fluid stroke into a start-and-stop slog.

Recovering your arms in butterfly means lifting your entire upper body, not just tilting your head, because your shoulders don’t have enough range of motion on their own to clear your arms over the water. Swimmers who try to recover using their neck and shoulders alone usually drag their arms through the surface instead of clearing it.

Common butterfly mistakes worth fixing early

A handful of faults show up constantly in beginner butterfly. Most of them trace back to timing rather than strength. USMS lists the big ones:

Recovering the arms separately or underwater instead of together and over the water.

Letting the hips sink during the pull without a compensating kick.

Trying to glide the way a breaststroker would. Butterfly punishes gliding hard, since there’s no phase in the stroke built to reward a pause the way breaststroke has.

Fatigue compounds all of this. Swimming butterfly while already exhausted just means swimming it badly, since a tired body can’t hold the timing that makes the stroke work. That’s part of why shorter, higher-quality repeats beat long grinding sets for beginners.

Beginner drills that build rhythm before endurance

Two drills come up constantly in butterfly coaching:

Single-arm butterfly has you breathe to the side, recover one arm with a straight-arm motion, and hold the other arm extended forward the whole time. This isolates the timing between your hips and your hand entry without demanding full-stroke stamina.

The 1-1-1 drill layers one stroke with the left arm, one with the right arm, and one full stroke. The sequence is repeated and eventually progresses to 2-2-2 as your timing improves.

Both drills work as low-intensity ways to rack up technique repetitions before you can hold a full-stroke butterfly for real distance. Pair them with dedicated dolphin-kick sets to build leg endurance separately, and with longer freestyle swimming to build the upper-body base that butterfly draws on without wearing down your form every rep.

Frequently asked questions

How do you swim butterfly without getting tired?

Most of what feels like exhaustion is wasted motion, not missing fitness. A mistimed kick or an early breath makes you fight the water, and that empties your tank by the second length. Fix the timing and the same swim suddenly feels a third easier at the same level of effort. Conditioning helps, but chase the rhythm first. You can’t out-train a stroke that’s working against itself. *

What is the timing for butterfly stroke?

The simplest way to hold it in your head is one wave, not four separate moves. The two kicks bookend each arm pull – one to launch your arms out for recovery, and one to catch your hands as they enter. The breath rides the same rise as the pull, rather than being its own action. When it clicks, the whole cycle feels like a single continuous motion looping back on itself.

How many kicks per stroke in butterfly?

Two. The most common mistake by beginners is not the count, but the balance. The second kick, which should lift your hips as your pull finishes, cannot be a token flick. If your hips feel like they’re dropping mid-stroke, a faded second kick is usually why.

Why is butterfly the hardest stroke?

Because it’s the hardest to fake. In freestyle you can power through a flawed catch and still move. Butterfly gives you nowhere to hide. The moment your timing slips, the stroke stops working, and you feel it instantly. Butterfly is also front-loaded; the first length often feels fine, but the wheels come off if fatigue degrades your timing. That’s why beginners are told to keep the reps short and clean.

Can you use a breaststroke kick in butterfly?

Not in high school. Under both NFHS and USA Swimming rules, the butterfly kick has to be an up-and-down dolphin motion, and a breaststroke kick is a disqualifying fault, right alongside a flutter kick. The “butterfly-frog” you might hear about is legal only in U.S. Masters swimming, which is an adult competition under a different rulebook. If you race high school or club, the dolphin kick is the only legal option, so it’s the one worth building from day one.

Your swimmer’s next step

Butterfly stops feeling impossible the moment the timing clicks, and it clicks faster when your swimmer stops treating the stroke as a strength contest. The place to start is single-arm drills, getting the kick-to-pull rhythm right at low intensity and letting the endurance build on top of technique instead of forcing both at once.
