Action essentials: first paddle with your hands, and then kick with your arms open. When paddling with your hands, don't move your legs, retract your hands first, and then slide for a period of time (about 1~2 seconds).

Coordinated action: hands forward, palms outward, inclined at about 45 degrees, little finger upward, breathing (inhaling) when both hands paddle outward, holding their breath when both hands paddle inward, and kicking and exhaling when both hands reach over the head. Freestyle: The arms are used for paddling and the legs are used for kicking.

The main points are as follows: 1, the body should be straight, and the leg surface should be just above the water.

2. After the body enters the water, stretch your hands and elbows, stretch forward, hold the water, and stroke your arms inward and upward. After the shot, the arm should be relaxed, move forward in the air, continue the next action, and cycle.

3. Put your legs together, bend your knees slightly, and draw water down. (stirring water)

Breathe when your head turns to the left and your right shoulder leaves the water.

5, the approximate rhythm: the left and right legs draw water six times, each arm draws water once, and breathes once.
