Now that you have been instructed on how to use the arms in breaststroke, we can get on with explaining the leg movements.

Don't get discouraged here as it is one of the hardest parts of swimming to teach.

When I was little I was always told: "kick like a frog, kick like a frog".

Hmm, it is really not quite so, but we can take a few pointers from the frog legs, so I guess the symbology is ok for the most part.

However, if you actually watch a frog to swim, you will see how different it is.

The main difference is that a frog propels herself forward with the membranes between her toes, so she snaps her feet back.

In breaststroke, we need to propel ourselves forward with our shins and partially with our feet at the end of the stroke. Therefore, we snap our shins back.

The issue with learning breaststroke leg movement is that most people start with a scissor kick which is totally wrong.

Scissor kick in breaststroke is not correct
Do not cut the water, but push off of it

So, when you try these exercises, please make sure you are not kicking toward the bottom with one leg and toward the surface with the other or worse yet to the sides.

Instead of scissors, think of it more like tongs.

Not crossing axis, but moving in the same horizontal axis toward each other.

First, note that when you are gliding with your legs extended, your ankles should be touching and your legs together.

This is how you start and finish the leg movement.

Second, let's discuss what makes you go forward.

The forward motion is caused by the inner shins of your calves and the inner ankles (when you get more advanced you can also add the bottom of your soles).

So, the more water you push backward with these parts of the leg, the more powerful breaststroke kick you will have.

Third, how to actually move your legs during the kick?

1). When your arms are on their way together with your elbows and your body is starting to lift out of the water for a breath, this is the time to start moving your legs.

Bend your knees and bring your heels straight back towards your butt.

It is important that you don't bring your knees forward.

Of course, there has to be forward motion with the knees a little, but it is very limited.

This way you are not creating a resistance movement by going against the water forward if that is the way you want to go.

The best way to practice this is to be on your back and when bringing your heels back to your butt, keep your knees underwater.

Your knees are about a foot apart in this phase of the stroke and your feet are turned out to the sides.

I repeat, do not keep your knees touching each other. Foot apart is about right.

2). The second phase is the propulsive kick itself.

Push on the shins to go forward
Push on the water with the inner shins to go forward

Kick outwards (better yet backward), however, not like you are kicking just outward (is this confusing?:).

You need to create sort of an outward + inward sweep with your legs below the knee where the inward/backward kick is the movement that gives you the surge forward.

Kicking breaststroke the right way
Learn to push water backwards with your kick

Remember what pushes you forward, the inner calves and inner ankles, so those are the ones that you need to be pushing the water with (viz the picture - don't laugh, I am no artist :)).

In order for the inner ankles to be effective, your feet are turned out as the red circle shows you on the video which is at the end of this post.

At the same time thrust forward with your hands and stretch your body on the surface, allowing your hips to rise to the surface.

Keep the kick narrow and strong
Turn those ankles inside out and put some pressure on them

3). To finish the kick and the final surge forward, you will use the soles of your feet.

Imagine, you have fins (flippers) on and your legs are straight. The only part of your legs you can move is ankles.

How do you make yourself go forward?

You use your ankles to thrust your feet and the soles of your feet (fins) toward each other to create the forward motion.

Now, let's see the whole breaststroke kick in practice. The best way to learn :)

The next video is an interesting example of a breaststroke kick during a breaststroke pull out.

Remember that in the breaststroke pull out one is allowed to combine the breaststroke kick with a very slight (not forced) dolphin kick.


It does not look the cleanest with the upper body arching so much, but the kick is nice.

Read more about the dolphin kick during breaststroke pullout.

So, now you might wonder, why the separate articles on arms and legs?

Well, research suggests that legs are much more important in generating powerful breaststroke, so it is important to break those apart.

However, note that in order to have an efficient, fast breaststroke, one needs to find an equilibrium and sync in the arm and leg movements.

No go on and try it out, first separate then together and play around with it.

And remember "Breaststroking is fun" :).

Just wanted to say thanks for the virtual swimming lesson. I am teaching myself to swim properly again, 10 years after school lessons ended, and I am utterly confused at times. And confusion generally means breathing in water, so you have hopefully reduced the amount of water I drink!

I remember doing this in training. Brings lots of pain if you not a breaststroker.

I am enjoying your site, might take me awhile to go through it all

Thanks for the info. I am a Canadian adult who is enjoying swimming lessons at the Rec Centre. It is nice to be able to learn on the internet too.
