Dr. Sargent's ingenuity has provided a simple and excellent chest expander. He rigs two ordinary pulleys over blocks some feet above the head, and from five to six feet apart, as in Fig. 8, and attaching weights at the floor ends of the ropes, puts ordinary handles on the other ends, and has the ropes just long enough so that when the weights are on the floor the handles are about a foot above the head. Now stand between and directly under them, erect, with the chest as full as you can make it, and keeping the elbows straight, and grasping the handles draw your hands slowly downward out at arm's-length, say about two feet. Next, let the weights drop gradually back, repeat, and so go on. This is excellent for enlarging the whole chest, but especially for widening it. A better present to a consumptive person than one of these appliances could hardly be devised. [Illustration: Fig. 8. A Chest-widener.] Again, to deepen the chest from front to back, he hangs two bars, B and C, as in Fig. 9, and attaches the weight at the other end, A, of the rope, the bar B, when at rest, being about a foot above the height of the head. Standing, not under B, but about a foot to one side of it, and facing it, grasp its ends with both hands, and keeping the arms and legs straight and stiff, and breathing the chest brimful, draw downward until the bar is about level with the waist. Let the weight run slowly back, repeat, and go on. A great advantage of both these contrivances, besides their small cost and simplicity, is that, as in nearly everything Dr. Sargent has invented, you can graduate the weight to suit the present requirements of the person, however weak or strong he or she may be, and so avoid much risk of overdoing. [Illustration: Fig. 9. A Chest-deepener.] In the exercises above named it will be noticed that there has been a sufficient variety for any given muscles to bring them within the reach of all. After this, how far any one will go in any desired line of development is a matter he can best settle for himself. What allowance of work to take daily will be treated of in the next chapter.
