Must keep you awake all night. Do you belong to the muscular type with thick legs or too much fat in your legs? If it is muscular and thick legs, I suggest you do more leg stretching exercises. The most important thing is to stretch the leg muscles to achieve the effect of stovepipe. Yoga is ok. If you are not muscular, do more aerobic exercise, play badminton, jump rope or play basketball, and massage with Ka Yu Xiu before rest at night.
