Hip drooping-kneel with both legs, keep your back straight, and straighten your other leg back parallel to the ground. Or in the same posture, straighten the other leg to the side until it forms a 90-degree angle with the body. Try to do this exercise in three groups (each group 10 times) on each leg.

Step 2 stretch your legs

Stand up-stand on your legs and keep your body straight. The other leg extends backward, so that the thigh is as straight as possible and parallel to the ground. Leg stretching can also be done sideways.

3. Lie on your side and lift your legs

Lie flat on your side on the bed or floor, with one leg close to the floor and the other leg lifted upward until the leg forms a 45-degree angle with your body. Then support your thighs on a table or chair at a 45-degree angle. Then lift the calf close to the floor and make it close to the thigh. This exercise can strengthen the medial and lateral muscles of the thigh, instead of just exercising the lateral muscles as before, thus maintaining the balance and symmetry of the thigh.
