Stretching exercise is the most effective way to make thighs fit: two hips droop, one leg bends and squats, the back stays straight, and the other leg stretches back to be parallel to the ground; Or in the same posture, the other leg goes straight to one 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. This exercise can also be done while standing-standing on your legs and keeping 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.
