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.
