Breaststroke Technique: Timing, Kick, and the Pullout

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

Breaststroke can be a frustrating stroke. It’s a strange combination of an unnatural movement, technical skill, and underwater pullouts – and any one of the three can be the difference maker in a breaststroke race.

This guide covers both halves – the surface stroke (kick, pull, timing) and the pullout that connects one length to the next – plus the rules that separate a legal breaststroke from a disqualified one.

It’s 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 breaststroke has these two halves so it makes sense when your swimmer talks about it on the drive home.

Swimmer, the rest of this is for you.

What makes breaststroke technique different from every other stroke

Breaststroke breaks its own rules compared to the rest of competitive swimming. U.S. Masters Swimming's breaststroke guide points out that it's the only stroke where you can't recover your arms over the surface of the water. It’s also the only one with a genuine pause built into every cycle of pull → kick → glide → repeat.

That pause is a feature, not a flaw. It's also why breaststroke rewards patience over raw aggression in a way freestyle and backstroke don't. Rush the glide and you lose the free speed it's supposed to give you.

The whip kick: where most of your propulsion actually comes from

Your kick, not your pull, does the heavier lifting in breaststroke. U.S. Masters Swimming (USMS) is specific about the mechanics:

Your feet turn outward and sweep backward with real rotation built in. It’s a completely different pattern from the up-and-down flutter or dolphin kicks used in the other three strokes.

The turned-out, rotating action generates more propulsion relative to effort than the pull does, which flips the usual swimming hierarchy where arms tend to dominate.

With the breaststroke, mobility drives kick quality more than raw leg strength. The more range of motion you have through your hips, knees, and ankles, the tighter and faster your kick can be without sacrificing power.

Swimmers with limited hip mobility often compensate with a wider kick. Read on to learn about the tradeoffs before making it a habit.

If your swimmer’s kick feels strong in practice but their knees ache the next morning, that’s a conversation to have with the coach before adding more kick volume. Breaststroke kick technique and joint health are closely connected, and a technical tweak often fixes a physical problem faster than rest alone does.

Breaststroke pull and the pause everyone rushes

Since both arms have to recover underwater, rather than swinging over the surface, the pull in breaststroke is shorter than in any other stroke. Your pectoral and lat muscles generate most of the pulling force, while your biceps contribute and your shoulders work overtime to stabilize the motion.

As a result, stronger swimmers with more shoulder range can generate a bigger, more powerful pull. Swimmers with less range or strength will move less water per stroke early on, until they’ve built these up through dedicated shoulder work.

What matters more than raw power, though, is timing the pull with the kick so that the limbs don’t work against each other.

Timing: the difference between gliding and fighting the water

Breaststroke timing comes down to this – what one arm is doing, the other should be doing too, and the same goes for your legs.

Pull while your legs are still recovering from the last kick, or kick before your arms finish their pull, and you're applying the brakes and the gas at the same time.

Stroke rate and glide length vary a lot between good breaststrokers. Some swim with long strokes and a big glide at a low stroke rate. Others swim with almost no glide and a much higher turnover. Neither approach is universally faster.

USMS points out that a stronger kick tends to support a lower stroke rate, since the kick alone can carry the swimmer further before the next pull is needed. Figuring out where you land on that spectrum takes real experimentation, not guesswork after watching other swimmers.

The underwater pullout: free speed most swimmers undertrain

The underwater pullout, which begins the moment a swimmer leaves the wall or the blocks, matters enormously, especially in short-course racing. It’s what separates the really fast swimmers from merely good ones.

According to USMS, some elite short-course breaststrokers spend more total time in their pullout than they do swimming on the surface.

A peer-reviewed breakdown of elite pullout mechanics published in Frontiers in Sports and Active Living describes how the modern pullout follows a defined sequence:

A passive glide in a streamlined position

An arm pull back to the hips

An arm recovery paired with the breaststroke kick

One dolphin kick somewhere in the sequence

That single dolphin kick became legal after a 2005 rules change in response to controversy at the 2004 Olympics over its use. Exactly where to place it – before the pull, or after it – doesn't have one settled answer. Some swimmers use a dolphin kick before starting their pullout; others at the end of the arm pull. There's no clear evidence one timing beats the other across all swimmers. * More than raw pulling power, though, what matters most is alignment, or staying perfectly streamlined from the moment you leave the wall through the entire pullout sequence. Sloppy alignment will create drag that eats the speed you generate through a powerful pullout. At higher levels of the sport, though, swimmers are generally taught to start the pullout with the dolphin kick rather than placing it during the arm pull.

The hardest part of a good pullout isn't physical. It's patience. You're having to hold a streamlined position and delay your breath while every instinct says to surface and start swimming. *

Rules that get breaststrokers disqualified

A handful of technical faults account for most breaststroke disqualifications, and knowing them helps you self-correct before an official has to. Per USMS, the big three are:

Turning one foot out while the other stays turned in, which creates an illegal scissors kick

Taking an extra dolphin kick beyond the single one allowed during the pullout

Letting your feet separate enough that the kick turns into something closer to a flutter kick.

Recovering your arms completely out of the water is also against the rules. Disqualification for this is rare, though, since any part of your arm staying submerged (even just an elbow) keeps you legal.

USA Swimming's official rules require that all arm movements while swimming breaststroke must be simultaneous without alternating movement. Your elbows must stay underwater except for the final stroke before a turn or finish, and your hands can't travel back past your hip line except on the first stroke after a start or turn.

The stroke cycle itself has a required order, too: initiate the pull with an outsweep → pull toward your body while your head breaches the surface, bringing your heels back for the kick → flare your feet as the kick begins → shoot your hands forward along the surface as your head returns to position → finish the kick into a streamline → touch at each wall (and at the finish) with both hands, separated but simultaneous.

Frequently asked questions

What is the correct timing for breaststroke?

One pull, one kick, one glide, in that exact order, with the stroke cycle rule requiring a single arm stroke followed by a single leg kick every time. Pull while your legs are still recovering, or kick before your arms finish, and you're fighting your own stroke instead of moving forward.

Why is my breaststroke kick illegal?

Most disqualifications are caused by either one foot turned out while the other stays in, an extra dolphin kick outside the one allowed during the pullout, or your feet separating enough that the kick turns into a flutter kick. Watch for these especially late in a race; fatigue can change your kick shape without you noticing it.

How long can you stay underwater in breaststroke?

There’s no distance limit on a breaststroke pullout – the 15-meter rule doesn’t apply here. What the rules require is that your head breaks the surface before your hands turn inward at the widest point of your second stroke after a start or turn. Wait too long to surface, though, and you’re usually losing speed, not gaining it.

What causes breaststroker's knee?

Repeated stress from the whip kick's outward foot rotation, especially at high training volumes. A review of swimming injury patterns has linked breaststroke specialization to higher rates of knee pain than reported by swimmers of other strokes, which is why coaches watch kick width and rotation closely instead of just adding more yardage.

Is breaststroke the slowest stroke?

Yes, among the four competitive strokes, breaststroke is the slowest. Both arms and legs recover forward underwater, which creates more drag than an over-water recovery allows. A strong pullout narrows that gap more than almost anything else a breaststroker can train.

Your swimmer’s next step

Breaststroke technique lives in two places most swimmers treat as separate: the surface stroke and the pullout. They need to be trained together. A perfect whip kick doesn’t matter much if the pullout alignment is loose, and a great pullout won’t save a stroke whose timing fights itself on every cycle.
