These same motions should be gone through with the right hand.
EXERCISE 7.
Bring the finger tips of the right hand together with the tip of the thumb, spreading the fingers at the middle knuckle and rounding the whole back of the hand. From this position snap the whole hand out flat, with the fingers spread wide apart. Do this forcibly. Quickly return to the original position and repeat the exercise twelve times.
This same exercise is to be performed with the right hand.
EXERCISE 8.
Raise your left arm so that the elbow is sticking out in front of you almost as high as the shoulder. Bend the arm at the elbow, so that the forearm reaches straight up in the air. Close your hand loosely. With a rotating movement of the upper arm, bring your fist down as low as it will go, still keeping the elbow at the same spot. Return to the original position. Repeat this exercise twelve times. At first it will be advisable to do this rather slowly and without too great effort, because of considerable strain in the region of the shoulder blade. Later, as the muscles become stronger and more supple, you can increase the speed and the intensity of the effort.
Repeat the same exercise with the right arm.
