1, Leg reduction: Sit with your back straight, then stand with your legs together and your heels on the ground with only your toes. Just keep this position. There is no time limit, this action can be done not only in the dormitory at night, but also in class and at work (if you are sitting in an office). Generally, the effect can be seen in one month, but the degree varies from person to person.

2, thighs: There is no particularly effective method at present, you can try massage. Sit on the bed with your legs straight, and then push down from the root of your legs with your palms in a leg-hugging posture. You can separate the thigh from the root of the leg, with the thigh pushing from the knee and the calf pushing from the knee to the ankle. Use some force, push the front and sides of your legs, and push the back with the strength of four fingers when holding your legs. This is an effective method that I know at present, but I can't see it in a short time. Can refer to it
