The first action: the opening and closing jump (a group of 40 seconds, five groups at intervals)
First of all, stand with your chest up and abdomen in, and then hang your arms naturally. Then our legs jump outward, arms and shoulders are parallel, and they are all retracted. Our arms extend upward again and then retract. Do this for forty seconds and divide into five groups. Don't just pay attention to speed, but be sure to pay attention to rhythm.
The second action: lie on your back with both ends of your legs straight (20 times)
First of all, lie on your back, then stick your upper body to the ground, lift your arms up, straighten your legs together, let your abdomen exert force, keep your legs still, then lift up, touch your toes slowly with your hands according to the rhythm of the action, and then slowly turn around, and repeat this for 20 times.
The third action: Bobby jumps (fifteen times)
First of all, you have to open your feet parallel to your shoulders, then slowly squat down, jump your legs back to your back, bend your arms and elbows down, then you can return to your original state (push-ups) when your chest touches the ground, and then repeat this action.
The fourth movement: the opening and closing jump supported by the flat plate (20 times)
First of all, you need to understand the God-like flat support, with your arms on the ground parallel to your body, then keep your body straight, jump your legs out and come back, and rest for ten seconds between each action, three to five groups a day.
