Vertical motion of staggered legs
Lie face up on the ground, cross your legs on the ground and put your head in your hands. Raise your legs until they are perpendicular to the ground, and then raise your head. Stop at the highest point and breathe once, then repeat.
Supine board movement
Hold the handle of the supine board with both hands, straighten your body forward as far as possible, and then contract your body with your abdominal muscles. In this stretching and contracting action, the abdomen is well stretched.
Long arm buckling motion
Lie face up on the mat, hands straight above your head, palms closed. Knees bent. Then push your upper body and shoulders up, but don't stretch your neck and keep your arms straight. Put it down again. Repeat.
Abdominal movement of lying down and lifting legs
This exercise also makes full use of the strength of abdominal muscles, focusing on the following strength. Exercise: Lie on your back with your hands at your sides and your feet crossed. Abdominal muscles lift legs hard and knees bend. Then put it down. Say it again. Because the action is relatively simple, we must rely on the strength of the abdomen rather than the strength of the thigh.
"cycling" exercise
Lie on the ground with your hands on your head. The left knee is bent close to the chest, and the right elbow rests on the left knee, at which time the right shoulder is also raised. Change the other side, that is, let the left elbow be close to the right knee. This is done alternately.
