[Illustration]
Open out the left hand before you, with the fingers close together. Hold
the thumb apart. Move the first finger as far toward the thumb and away
from the other fingers as possible, and back again. Do this gently and
easily five times.
Now let the muscles of the hand and fingers become tense, so that as you
draw the finger over towards the thumb with one set of muscles, the
opposing set resists the motion. Repeat this ten times.
Go through this same movement with each of the other fingers of the left
hand and then with each of the fingers of the right hand.
