Running around the playground is running around the track on the playground, which is a kind of exercise. For beginners, because of their limited strength, they are more willing to run in places where there are few people around. On the one hand, they are a little embarrassed about running.

On the other hand, it is also difficult to predict the unexpected situation during running, for fear of embarrassing yourself. After gradually adapting to running life, people can choose more places to run, either on the road or in the park, but there is one place that many people hate, that is, running in circles on the playground.

Run operation:

Action essentials: When hearing the preface of "running", make a fist with both hands quickly (four fingers are curled, thumb is attached to the first joint of index finger and the second joint of middle finger), and when reaching the waist, it is about the same height as the belt, with the fist heart inward and the elbow slightly inward. After hearing the "go" command.

The upper body leans forward slightly and the legs bend slightly. At the same time, the left foot leaps about 85 cm by the pedal force of the right palm, the forefoot touches the ground first, the body center of gravity moves forward, and the right foot moves according to this method.

The upper body is upright, and the arms naturally swing back and forth. When swinging forward, the big arm is slightly straight, the elbow is attached to the waist, and the small arm is slightly flat and slightly inward. The distance between the inside of the two fists and the buckle line is about 10 cm. When swinging backwards, put your fists on your waist. The traveling speed is 170- 180 steps per minute.
