Hold your left arm across the chest palm up, but with the wrist bent as far down as possible, the fingers easily curled. Place the right arm in a similar position, but with the palm down, having the wrist of the right hand bent upward and fingers similarly curled. Lay the finger tips of the right hand on those of the left. From this position twist the forearms in opposite directions until the finger tips again come together, this time the palm of the right hand bent up, and of the left bent down.
Reverse the motion and repeat the exercise twelve times.
EXERCISE 16.
Extend the left hand and close the fingers down to the palm, keeping the knuckle joints straight and bending only the two outer joints.
Holding the other fingers motionless, straighten out the index finger. You must be careful throughout the entire exercise, never to move the knuckle joint. Repeat five times without muscular resistance, then go through the exercise with the muscles tense, so that one set resists the motion of the other.
Practice this exercise on each of the remaining fingers on the left hand and on all of the fingers of the right.
EXERCISE 17.
Stand erect, shoulders back, and without bending forward, lean far over to the right from the waist line. As you do this, let the right hand bend toward the left knee. While in this position, make a short but strong thrust, entirely from the right shoulder which will bring the fingers of the right hand possibly an inch nearer the left knee. Straighten up, bend to the left and thrust out the left shoulder. Repeat this exercise first with the right and then with the left twelve times.
