Exercise times: twice a day, twisting your legs 5 times each time.

Efficacy: strengthen the key ligaments of calf muscles and ankles.

This is a thin thigh (you can thin your thigh when you are lying at home)

Lie flat on your side with one leg, lift one leg perpendicular to the bed, and then put it down. It's best to stay away, then repeat this action until your legs are sore, and then repeat this action on the other side, 3-4 groups a day.
