How to judge the cause of X-O leg and the appropriate exercise correction method?

Sit in the chair first and put your legs together. Tie rubber bands evenly below the knee and above the heel. If the adhesive used is not an elastic rubber band. Before binding, put towels on the inner heel and knee to avoid pain. When binding for the first time, don't be too tight. Stand up after tying, remember to keep your body straight, hold your head up and stand for about 15 minutes. If you feel pain or numbness when standing, you are tied too tightly. At this time, you have to take it apart and tie it back. It's best to tie it twice a day. You can also squat down with your hands on the railing or the back of the chair. The repetitive action of standing is about 15 minutes at a time. Squat correction exercises the muscles inside the calf. Stand with your feet shoulder-width apart, with your feet slightly flexed and kneeling down. There's no need to squat completely. Do 2 ~ 4 groups every day, 20 times in a group. Stick to it for a month and you will see the effect.
