How to teach yourself how to swim quickly: 1, go to the swimming pool with your partner, and get familiar with the water in the shallow pool first; 2. Learn to hold your breath again: breathe in with your mouth in a shallow pool, dive into the water, persist, exhale slowly with your nose and mouth underwater, get up, and practice until your back can float and your stomach is full of gas, so that you can float and learn easily; 3. Learn underwater and water breaststroke: breathe in with your mouth in the shallow pool, move your center of gravity forward, dive into the water, kick your legs first, then paddle with your hands, turn your feet 90 degrees outward, kick them 65 degrees horizontally, then clamp your legs hard and move forward quickly; Pull your hand back 30 degrees to both sides; Breathing: When you push your legs forward with your hands, your head will spit out 80% of the air through your nose and mouth underwater. When the hand is paddling and lifting the elbow, the head will be raised to inhale through the mouth, and then the legs will be retracted, so that people can practice with their chin held, and then learn freestyle, backstroke, butterfly, treading water, diving, turning and so on.
