[Illustration]
Open the left hand with the fingers together but the thumb out of the
way. Move the index finger so that the tip of it circles around down
toward the palm, over to the thumb, to the back, and returns to the
original position. Keep the fingers straight all of the time. Repeat
this without muscular resistance five times.
Now stiffen the muscles of the finger, so that one set resists this
motion, while the other set overcoming the resistance, causes the finger
to circle as before. Repeat five times.
Go through the same exercise with each of the other fingers of the left
hand, and then with all of the fingers of the right hand.
