Excuse me, the ventilation skills in breaststroke ..

From slow to fast, accelerate evenly and exhale smoothly;

When a breaststroke swimmer breathes, he straightens his hands, leans forward, sinks his hands, then turns his hands outwards, slightly bends his wrists, and paddles separately below the syncline.

While pressing water outward with both hands, slowly lift your head out of the water to breathe air, then press your palms against your chest and your elbows against the inside of your body. At the same time, close your chin, face down, palms up and hands folded, just like washing your face. Then stretch your hands forward, close them, palms down, exhale slowly and float for a while. This cycle is the action of breaststroke paddling and breathing.
