Sit and lift your legs: Sit naturally with your legs flat at a 90-degree angle. Try to lift your heels for more than ten seconds, then put them down and repeat until your calves feel tired. This action can tighten the hips and thighs and make the muscles elastic without thickening the hips, thighs and calves.
Sit up straight and raise your heels: first, sit up straight, hold both sides of the chair with both hands, lift your legs and straighten your toes, at the same time tighten your abdominal muscles and slowly hook up your toes and put them down. This action can effectively tighten the calf, thigh, arm position and abdominal muscles.
