When a limb is used to turn the body of another, the individual turned must resist the force of the thrower by moving the limb against the force . 
An example of this point is the stunt in dual gymnastics in which one performer turns a somersaults by placing his heal in the hand of another with his legs outstretched . As he jumps in the air the person holding the heal lifts up the leg as a lever to give rotation to the body of the jumper . Unless the leg of the jumper is held rigid , it will merely rise in the air without giving his rotation . :D
