EXERCISE 24.
Lay the right hand flat on a table or other hard plane surface, fingers and thumb far out-spread. Press firmly with the whole hand on the table. Continuing this downward pressure, exert an upward pressure against it with the finger tips, and raise the body of the hand about 1½ inches from the table top. Throughout this entire exercise try to keep the back of the hand parallel with the table. After you have reached the desired height, press the hand down to the table top again against muscular resistance. Repeat this exercise ten times.
Perform the same exercise with the left hand.
