The posture is the same as in Chinese martial arts horse riding squatting crotch action or called standing pile action, squatting horse stance. The patient’s legs are separated, the distance between the two feet is slightly wider than the shoulders, the body remains in an upright position, not leaning forward, the back against the wall, at this time the knees begin to bend and squat. The bending angle of the knees varies according to the patient’s physical condition and muscle strength. If the patient’s physical condition is good, good thigh muscle strength, squatting angle can reach 90 ° flexion, if the patient is weak, thigh muscle strength is weak, both knees can be lightly flexed, this time the half squat position is higher, the patient more effort, can be later with the exercise, thigh muscle strength increases, and then increase the angle of the knee flexion. Each patient will have a painful angle when squatting, some squatting to 30° pain, some squatting to 60°, or 40° pain. It is best to avoid the painful angle when practicing static squats. If squatting to 30° hurts, you can continue squatting down to 60° to avoid the 30° painful angle, and vice versa. The duration of a squat varies greatly from person to person, all squatting until they can’t hold on. Rest a minute between squats, do not rest too long. Then practice the second squat, and so on, and continue to practice 1-3 times a day. 30 minutes is the day of a squat exercise. Depending on your physical condition, you can decide how many times you want to practice. The next morning after waking up, the thigh muscles slightly sore and swollen to prove that the amount of yesterday’s appropriate, you can slightly increase the exercise, if there is no feeling, indicating that the first day of practice is not enough, you need to increase the amount of practice, if there is pain, you need to reduce the amount. If numbness appears, you must stop practicing and continue practicing after the numbness disappears.
