1, the back foot of the step should move forward as far as possible, basically in a straight line with the main leg, with the center of gravity between the two feet half crouched, with the upper body leaning forward 45, the shoulders and chest facing the ground and the top of the head facing forward.

2. When turning over, the crotch is an "open" and "closed" relationship. Before turning over, 1/2 crotch passes through the waist at the same time, and the top crotch opens back actively. When turning over from the back 1/2, the side waist and crotch should take the initiative to "close" to the front, with the trunk at the back.

3. The arm is driven by the first arm to take away a vertical circle, and the back of the hand always faces straight ahead.

4, eyes should look at a point on the ground, in the process of turning over, there must be the action of raising your head.

5. Be smooth, dexterous and have a "power point" when turning over quickly.

Error-prone crossover point:

(1) Because the top and buttocks are inactive, the phenomenon of stepping on the waist and buckling the buttocks appears.

(2) the upper body is not relaxed enough, the front waist is ribbed, the side waist is not in place, and the front chest is retracted.

(3) Step forward and backward, and turn over askew. When the hind legs are "folded" at 1/2, the hind legs are not "folded" together.

(4) The arm is not straight, upright or round.
