The breaststroke kick is the kick used by the breaststroke swimmers.
While at first glance its technique may look simple, there are a few subtleties to take into account for the kick to be executed with maximum efficiency.

Breaststroke Kick Phases
The breaststroke kick can be broken down into the following phases:
- Initial position – glide
- Leg lift and back into glide
We will describe those phases in more detail below.
Initial Position – Glide
For this explanation, you start in the glide position:
- Your arms are extended forward.
- Your legs are also extended, held together, and your feet are pointed.
- Your head is in a neutral position, and you are looking downwards.
The leg recovery starts at the end of the propulsive phase of the arm stroke (insweep).
At that moment, your head and shoulders are above water, and your hips are slightly underwater so that your body is inclined.
Your legs are straight and kept together, with feet pointed.
At the beginning of the leg recovery, your knees bend, and your feet move towards your buttocks. It’s a movement where the lower leg folds onto the upper leg.
At the same time, your feet bend towards the tibia (dorsiflexion).
Your knees should be kept close together without touching each other.
Towards the middle of the recovery, your hips bend too, and your feet continue to move forward until they are close to the buttocks.
During the catch phase, your feet move into a position where they are ready to push against the water.
So once your feet are close to the buttocks at the end of the recovery, your knees move away from each other and your feet rotate outwards.
The inside of your feet are now facing backward, and your feet are turned outwards.
Once the catch has been made, you should sweep your legs backward and outwards while pushing against the water with the inside of your feet and lower legs.
You continue to extend your legs backward but now sweep them inwards.
At the same time, your feet which were rotated outwards rotate inward.
At the end of the insweep, your legs will be pressed together. Your feet should nearly be in contact.
Leg Lift and Back into Glide
Once your legs have been brought together at the end of the insweep, they will move upward due to inertia.
Your feet which were in dorsiflexion will now move in plantar flexion (feet pointed).
You are back at the beginning of the cycle and you glide for a few moments in this streamlined position.
Additional Swimming Tips
As mentioned above, during the leg recovery, at first you only bend your knees.
Doing so ensures that your legs recover in the shadow of your body, decreasing drag.
Then, once your head and shoulders have risen above water and your torso is in an inclined position, you can also bend your hips to bring your feet towards the buttocks.
Because your body is an inclined position, you don’t need to bend your hips that much to keep your feet below the water surface.
Learning the Breaststroke Kick
