1, use both hands and feet. Make sure your body and limbs are perpendicular to the water. If you cross your body and start kicking and paddling in the water, you are already swimming, not treading water.

2. Keep your head up and breathe normally. Keep your head out of the water and try to breathe slowly and regularly. Slow down your breathing, calm yourself down and relax, and store energy for treading water for a longer time.

3. Swing your arms horizontally. If you touch your arm up and down, it will move your body up and down, because your arm is connected with your body. The correct way is to let the arm stroke back and forth in the horizontal direction, and the fingers are close together.

4. Draw a circle with your legs or kick back and forth. If you choose to circle your legs underwater, don't toe down or your feet are stiff; If you choose to kick back and forth, keep your toes down and kick back and forth.
