The second trick is to sit on the side of the chair with one hand akimbo, and at the same time prepare an object with a roller about the height of the chair and put it on the side of your body. Then put your hand on the object, slowly push it out, push it to the extreme, and slowly withdraw it. Repeat this action on the other side, and the whole group of actions is completed!
The third measure is to sit up straight first, and then slowly tilt your upper body backwards, while your feet are off the ground. At this time, the feeling of the abdomen will deepen with the backward inclination of the abdomen. Then take turns to clip your feet to your abdomen and clap your hands at the inner clip. It should be noted that when your feet are clamped, your upper body should also move and keep the strength, otherwise the strength will be relatively gentle. This action is done by 10 8 in a group, about three groups at a time.
