Breaststroke Kick
At least 15 meters of breaststroke kick with the hands resting at the sides of the upper body. The feet rotate outward with bent knees and sweep together in a semicircular motion, followed by a glide phase after each kick. Breathe after every kick, when the legs are fully extended. Preparation for the full breaststroke technique.
Preparatory exercises

Breaststroke kick with both legs
The child pushes off from the pool wall, holds a vertical position and performs a breaststroke-like kick with both legs — a simplified breaststroke kick where the knees are never fully drawn in. This introduces a familiar element in a new vertical form: the breaststroke kick is the closest learned kick to treading water, making it ideal for introducing the concept quickly.

Touch hands
The child brings their feet to their hands, which rest at their sides. This teaches the correct leg movement and prevents two common mistakes: kicking with half-bent legs, or stretching the legs completely and opening and closing them like a jumping jack.

On the back
The child clasps a swimming board and floats on their back, then stretches the legs slowly and in a controlled manner and pulls them back up without spreading the knees, with a short break between each kick. This teaches efficient leg movement without tiring quickly. Later, set a target: for example, cover ten meters with a maximum of seven leg kicks.

The mountain and the moon
The sternum thrust is learned with this land exercise: the mountain is the bent knees, the moon the synchronized semi-circular leg movement. Sit opposite your child and demonstrate step by step: 1) legs and feet fully extended, hands supporting behind; 2) pull the legs up, knees touching, feet together and extended — the mountain; 3) turn the feet outwards, heels still touching; 4) move the feet forward in a synchronized circular motion along an imagined circle (the moon), turning them inwards halfway until legs and feet are extended and closed again. Repeat dozens of times, slowly at first, then faster, waiting at least two seconds between kicks. Focus on the circular movement and correct foot position. Once mastered on land, sit on a board at the pool edge and repeat with the legs in the water, displacing as much water as possible.
Common mistakes

Feet not turned outward
As previously mentioned, turning the feet outward is a crucial component of the breaststroke kick. Many children fail to grasp this concept and forget this important detail once they are in the water. For this reason, the "Mountain and Moon" exercise should also be practiced with their feet in the water. This helps them understand the difference in water resistance and its impact on propulsion.

Scissor
In the scissor kick, the hips are tilted to the side, and the kick is not synchronized but instead offset laterally. This error can be corrected through the previously mentioned "Moon and Mountain" exercise and the back-floating drill.
