Then I recommend a mechanical method to you: mechanical therapy. As long as you do it three times a day, you can grow at least 3 cm tall and become graceful after three months. It can be said that it is a beauty gymnastics that kills two birds with one stone. (1) Put your feet together, stand up straight, move one leg back half a step, then bend your upper body forward, keep your knees bent, and let your fingers touch the ground, and so on 15 ~ 20 times. This action can make the lines of thighs and knees graceful and soft, and make the left and right legs symmetrical. (2) Open your feet for 30-60 cm, stand up straight, put one leg back for half a step, and then twist your upper body so that your fingertips can touch the toes on the other side. And do 10 ~ 15 times continuously. This action can make the lines of the two wrists graceful and soft, narrow the waist circumference and correct the curvature of the spine. (3) Open your feet for 60 ~ 70cm, put one leg back for half a step, then raise your arms to shoulder height, and then throw them back horizontally. Twist 7 times in the direction of long legs and 4 times in the direction of short legs. This action can tighten the waist and make the figure beautiful. (4) Face the wall, keep a distance of 30cm, stand with one leg back half a step, open the heel, let the toes face the inside, then press your hands on the wall, hold your chest out, bend your legs, protrude your hips backwards, and put your knees together. Do it 20 to 50 times in a row. This action can displace the femoral joint, radically solve the problem of uneven legs, and make the leg lines beautiful. (5) Make a waist pillow that is cm long and twice as wide as your wrist, put one leg back half a step, sit deeply in the chair, then lean back with your shoulders and hold your chest out for 20 times in a row. This action can cure fatigue and shoulder pain, and it can also shrink the abdomen. (6) Pick up a rope and stand, put one leg back half a step, and then jump rhythmically 60 ~ 70 times in this position. Skipping rope is a good whole-body exercise, which is not only of great help to health and beauty, but also can contract the muscles of the whole body and increase the height. (7) Sit on the calf, put the knee of one leg back 3 ~ 5 cm, pull the shoulder back, and lift the arm straight up. In this position, lean forward and get as close to the floor as possible. Do it 20 ~ 40 times in a row. This action is the most effective exercise to correct the cat's back, which can not only straighten the back, but also beautify the lines of the wrist. (8) Sit down, tie the upper part of your knees with cloth, hold the calf with both hands, keep the knee of one leg flush with the knee of the other leg, then bend your body with both hands to make your chin touch your knee for 20 ~ 30 times in a row. This action can tighten the hip muscles. (9) After finishing the above eight movements, don't take the cloth off your knees for the time being, put a pillow on your back, straighten your legs and lie flat 15 minutes. If you have cold syndrome, you can tie a cloth to sleep at night, so that the cold syndrome will be better after a while. These are the most effective exercises for people with cat backs and O-feet.
