1, set off first, and then press the instructor's password.

2. "Step by step, just step by step, 1, 2, stop." The instructor shouted slogans while training and explaining. "After hearing the password to go forward, kick your left foot forward about 75 cm, straighten your legs, press your feet down, and your feet are parallel to the ground, about 25 cm from the ground."

3. Action essentials: After hearing the command of "Forward-Walk", kick the left foot forward about 75cm (waist straight, toes pressed down, feet parallel to the ground, about 25cm off the ground), so that the whole foot touches the ground with proper force and the center of gravity moves forward. The right foot moves according to this method, and the upper body stands upright and leans forward slightly; Hold your fingers lightly, stick your thumb directly to the second section of your index finger, and bend your elbow when your arm swings forward; Forearms are slightly horizontal and palms are slightly downward and inward; The lower edge of the wrist is about 10 cm higher than the lowest button and about 10 cm away from the body. When swinging backwards (right palm of left hand, left palm of right hand), the front side of wrist is about 30 cm away from the trousers seam. When you hear the command of "Stop", your left foot will touch the ground half a step forward (toes are about 30 degrees outward), your legs will be straight, and your right foot will take a shortcut to approach your left foot quickly to establish a positive posture.
