1, put the pillow in the middle of the calf and sit by the bed, with the big calf and calf at a 90-degree angle. Slowly lift the calf, hold this position for about three seconds, then put it down and repeat the action ten to fifteen times.

2. Lie on the bed and straighten your legs. When one foot moves, one foot straightens out. Do it twenty to thirty times in turn until the calf feels tired.

3, lying flat on the bed, big nest+massage exercise. Put your hands behind your waist, lift your legs up and push your feet in the air. You can rest for about 30 minutes!

4. Lie on your back, look straight at the ceiling, don't bend your knees, put your legs together and cling to your chest, then lift it up, close it again, and repeat this action 15 times.
