EXERCISE 2.
Lift your elbows nearly as high as your shoulders. Lay your left hand, palm up, straight across your chest, so that there is a straight line from the elbows to the finger tips. The fingers of the right hand with the palm turned down are laid on the fingers of the left. Twist the hands and forearms in opposite directions, until the hands come again into a similar position, but with the palm of the right hand up. Reverse the action briskly. Go through the cycle twelve times.
