EXERCISE 1.
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.
