First, understand the essentials of correct posture. You can use the method of ballet body training, with heels together and feet open 180 degrees to form a "one" character.

Second, use corrective shoes. Body-shaping shoes, also called body-shaping training shoes, are high in the front and low in the back, which is the same as the method of raising the front foot to correct hunchback, but this method is simpler, more active, more regular and easy to adhere to for a long time.
