To become aware of your whole movement with the legs lift both arms over your head and start to swing your legs. Look at the shadow of your arms and see how they move as a result of your moving legs. The opposite to this drill is to have a friend swing and hit your legs with a stick as you keep your arms in the air and this will help you relax more by spreading your awareness over your entire body and gaining more relaxation and freedom as a result. Train honestly.
