[Illustration]
Extend the fingers of the left hand, with the little finger away from
you and the thumb opened and pointing away from the palm, that is toward
your right. Bring the index finger down until it is at right angles to
the palm, bending only at the knuckle joint.
Let the knuckle joint straighten up again and at the same time bend the
other two joints of the finger, so that the finger tip goes down to the
palm of your hand. Repeat this exercise five times without resistance,
and then five times with resistance.
Continue the exercise of each finger of the left and right hands.
