EXERCISE 3.
Open the left hand out flat with the fingers loosely apart.
Grasp the little finger with the thumb and fingers of the right hand. Very gently bend it backward, as far as it will go without straining. You must be careful not to overdo this at first. Now bend it forward to the palm; back again and to the right and left.
Do this six times, allowing the little finger to move freely.
Now repeat the exercise, only instead of allowing the little finger to move freely, try to hold it rigid and immovable. Of course the muscles of the little finger will be unable to stand the greater strength of your right hand, and it is intended that the finger should move, but in each case it should move against the resistance of the finger muscles. Repeat this exercise against resistance fourteen times.
Go through this entire process with each of the other fingers and the thumb of the left hand. Then take up the exercise with each of the fingers of the right hand, moving them with your left.
