EXERCISE 5.
Put your right hand and arm down at your side, fingers extended. Keeping the elbow and upper arm close to the body, bend the arm briskly at the elbow, still keeping the hand open, and in a straight line with the forearm. Repeat this exercise twelve times with the palm of the hand turned toward the shoulder, and twelve times with the palm of the hand turned away from the shoulder.
Now raise the upper arm, so that the elbow bends slightly upward from the shoulder. Repeat the same bending action of the elbow twenty times. The position of the hand is immaterial in this exercise.
Go through these motions with the left arm.
EXERCISE 6.
Hold your left hand up in front of you with the palm facing you. Press the index finger and the middle finger tightly together. Bring the two still held tightly together down to the palm, and then back straight again, quickly, briskly and with muscular resistance. The motion should be from the knuckle joint. Naturally the other fingers will have a tendency to curl. It makes no difference if they do. Repeat this exercise twenty times.
Next practice this exercise using the middle and the ring fingers pressed together, letting the little finger and the index finger remain as straight as possible.
Do the same exercise with the little finger and the ring finger together.
