[Illustration]
Hold your right hand before you, double up your fist tightly, thumb on
the outside of the fingers. The hand turned with the palm side facing
you. Open the hand briskly and with considerable effort, letting it turn
around, so that the back of the hand is now turned toward you. Be sure
to get this point and turn the hand around as you open the fingers. As
you open the hand, be sure to keep the fingers stiff and bend them back
from the wrist as far as possible. Repeat this exercise twenty times.
