1. First, let yourself lie flat on the yoga mat, raise your hands, and then get up and touch your toes. Lift your feet when lying flat, making your abdomen feel nervous. Note that when we lie down, we don't lie down completely. Our heads and shoulders don't touch the ground completely. Train 4 groups, each group 12~ 15 times.

2. Lie on your side, grab your head with both hands, and then bend your feet upward. Let your side abdomen feel stretched, and pay attention to bending and stretching your body and feet to each other at the same time during practice. Train 4 groups, each group 12~ 15 times.

3. Let your body lie flat on the ground, lift your feet high, and then bend over and stretch back. Let your lower abdomen feel curled up, control the speed during training, not too fast, and ensure the quality of each movement. Exercise in 4 groups, each group 12~ 15 times.

4. Arch your knees first, then lift them slightly, hold them with both hands and swing from side to side. When practicing, the rotation angle should be in place, so that the side abdomen of the body has a deep sense of curling. Exercise in 4 groups, each group 12~ 15 times.

5. The last action is the crowning touch, and we have to do a set of abdominal stretching. First of all, let your hands stand straight, bend forward and stretch your abdomen. Then bend down, straighten your hands and do the second abdominal stretching.
