A weak breaststroke kick can make every length feel harder than it should, even when your arm pull looks fine. The breaststroke kick is where much of the stroke’s propulsion comes from, so this guide breaks down the movement, timing, common mistakes, and practical drills that help you swim farther with less wasted effort.
The fastest gains come from cleaner timing and a sharper foot position
- Recover narrowly by bringing the heels toward the hips without pulling the knees too far forward.
- Turn the feet outward so the inside of the lower legs and feet can press against the water.
- Kick in a circular whip, then finish with a tight, streamlined squeeze.
- Glide after every kick instead of rushing into the next pull.
- Practice with short drills before adding speed or long repetitions.
The movement that makes breaststroke efficient
The breaststroke kick is not a simple backward push like freestyle or backstroke kicking. It is a compact whip action in which the feet rotate outward, catch the water, and snap backward before the legs come together.
I find that swimmers often focus too much on how wide they can spread their legs. That usually creates drag. The real goal is to create pressure with the feet while keeping the recovery phase small, controlled, and close to the body.
The movement has four parts:
- Recover: Bend the knees and bring the heels toward the seat.
- Set the feet: Flex the ankles and turn the toes outward.
- Whip: Press the feet backward and slightly outward, then sweep them inward.
- Streamline: Lock the legs together and let the body travel forward.
The kick should finish with the feet touching or nearly touching. This closing action matters because it removes resistance just as the propulsive phase ends. U.S. Masters Swimming describes this as one of the most technical kicks in swimming, and that matches what I see on deck: small changes in ankle position can matter more than simply kicking harder.
How to perform the kick step by step
Start with the recovery
After the glide, bend your knees while keeping the thighs relatively quiet. Bring the heels toward the hips, but avoid dragging the knees under your chest. The knees should stay roughly within the line of the body, because an exaggerated recovery acts like a brake.
Think about moving the heels first, not throwing the knees forward. This cue keeps the lower legs ready for the next phase without creating a large frontal surface in the water.
Set the feet before applying pressure
As the heels rise, flex the ankles so the soles face backward and slightly outward. Then rotate the feet outward. This is the position that allows your feet and inner calves to hold the water.
Many beginners try to point the toes like a ballet dancer. That is useful in freestyle, but it reduces the surface available for this movement. In breaststroke, flexed ankles and turned-out feet are part of the propulsion, not a technical flaw.
Whip the legs around
Drive the feet backward and outward in one connected motion. Once the feet have pressed behind you, sweep them inward and finish with the legs together. The action should feel like closing a pair of doors, not stamping downward.
Keep the movement underwater. A kick that breaks the surface usually wastes energy and can lift the hips or disturb your body line. The best pressure is directed backward, with only enough outward motion to help the feet catch the water.
| Phase | What to feel | Common warning sign |
|---|---|---|
| Recovery | Heels fold toward the hips | Knees slide too far forward |
| Foot setup | Ankles flex and toes turn outward | Feet point backward like freestyle |
| Propulsion | Feet press back, then sweep inward | Legs separate without catching water |
| Finish | Legs squeeze together and streamline | Swimmer starts the next pull immediately |
Timing the kick with the pull and glide
A technically strong kick can still feel ineffective if it arrives at the wrong moment. Breaststroke works best as a rhythm of pull, breathe, recover, kick, and glide. The kick should help you extend the body forward after the arms return to the streamlined position.
During the arm pull, the body rises slightly and you breathe. As the hands shoot forward, the legs recover. When the arms are nearly straight, the feet are set and the kick begins. The legs then snap together while the body returns to a long, narrow line.
I often tell swimmers to make the glide their reward. Hold the streamlined position for roughly one to two seconds at an easy pace, or until you feel the forward speed begin to fade. Competitive swimmers may use a shorter glide, but rushing through it usually increases stroke count without improving speed.
The right amount of glide depends on distance and skill. A 25-yard sprint demands a more aggressive rhythm, while a relaxed 200-yard swim benefits from a calmer kick and longer line. The principle stays the same: finish the kick before starting another pull.
Common mistakes that waste the kick
Pulling the knees too wide
Wide knees expose more of the legs to the water and slow the body during recovery. This mistake is especially common when swimmers try to create a bigger kick. In practice, a narrower recovery with better foot rotation usually produces more useful force.
Keeping the ankles loose
If the ankles remain floppy or pointed, the feet cannot push effectively. The legs may move energetically, but the water slips around them. Work on ankle flexibility outside the pool, but do not force a painful range of motion.
Kicking straight backward
A straight backward kick resembles a shortened frog kick without the important outward foot position. It can feel powerful, yet it often produces little forward movement. The feet need to turn out, catch the water, and then finish inward.
Starting the pull too soon
This is the mistake I notice most often in otherwise capable swimmers. They complete the kick, immediately bend the elbows, and lose the glide. Give the body a brief moment to travel. Distance per stroke matters more than frantic movement.
Using the hips instead of the feet
The hips and thighs should support the movement, not dominate it. If the entire body twists or the knees jerk sharply, the kick becomes unstable. Keep the upper body quiet and let the lower legs and feet do the precise work.
There is also a rules issue for racing. In regulated breaststroke, both legs must move simultaneously, and alternating or scissor-style actions are not legal during the normal stroke. Recreational swimmers have more freedom, but learning the legal pattern is still useful because it encourages symmetry and control.
Drills that make the movement easier to feel
Back kick drill
Float on your back with your arms relaxed by your sides and practice the leg action slowly. Your hips should stay near the surface while the heels recover, the feet turn out, and the legs whip together.
This drill removes the distraction of breathing and arm timing. If your knees sink deeply or your feet splash, reduce the size of the movement. The goal is quiet, underwater pressure, not maximum effort.
Streamline kick drill
Push off the wall in a tight streamline and complete one kick at a time. Wait until the glide slows, then repeat. This teaches you to separate the propulsive phase from the recovery and helps reveal whether you are losing speed through poor alignment.
Three kicks and one pull
Use three controlled kicks followed by one arm pull. Keep the pace easy and focus on making each kick identical. This drill gives you more time to notice the ankle position and the inward finish.
Once the movement feels consistent, reduce the pattern to two kicks and one pull, then return to full breaststroke. U.S. Masters Swimming uses progressions like these to help swimmers transfer isolated kicking skills into the complete stroke.

A simple 15-minute practice set
- 4 x 25 yards back kick, easy effort, with 20 seconds rest
- 4 x 25 yards streamline kick, focusing on a quiet recovery
- 4 x 25 yards three kicks and one pull
- 4 x 25 yards full breaststroke, counting strokes per length
Stop or slow down when the knees begin to widen or the feet lose their outward angle. Technique work becomes conditioning very quickly, and fatigue can hide the original problem instead of fixing it.
Build a cleaner kick without forcing it
The most effective breaststroke kick is not necessarily the biggest one. It is the one that creates backward pressure, closes quickly, and leaves the body in a long line with minimal drag.
When I coach this movement, I look for three simple checkpoints: heels recover quietly, feet turn out before the push, and legs finish together before the next pull. If those three pieces are reliable, speed usually improves without adding more effort.
Give yourself several sessions to build the pattern. Ankle mobility, hip comfort, body position, and race distance all affect how the kick should feel, so do not copy someone else’s range of motion blindly. A compact, repeatable movement that keeps you moving forward is a much better target than a dramatic kick that creates drag.
