=Exercise No. 8.=--Stand, with hands on hips, sway the body in a circular manner, to the right, left, backward and forward. It is a splendid exercise for stimulating the intestines. [Illustration: EXERCISE NO. 8.--Standing, hands on hips, circulatory body exercise, swaying body in circular manner right, left, back and forward.] =Exercise No. 9.=--Reclining on back, with both hands, grasp some object back of head; now, holding the knees rigid, raise both feet to a vertical position. This exercise is rather severe at first. It should be repeated several times. It exercises the abdominal and hip muscles. [Illustration: EXERCISE NO. 9.--Reclining, hands grasping something back of head, raising both feet to vertical position.] =Exercise No. 10.=--Reclining on stomach, raise left leg, with knee straight, as high as possible; same with right. Repeat these exercises several times. This exercise is tiring at first. It limbers up the joints. For a person who has been accustomed to inactivity, as in the case of bedridden invalids, this is a valuable exercise. [Illustration: EXERCISE NO. 10.--Reclining on stomach, raising left leg with knee straight, as high as possible; same with right.] =Exercise No. 11.=--Recline on stomach, grasp dumb-bells in both hands, raise arms from hanging [Illustration: EXERCISE NO. 11.--Reclining on stomach, grasping dumb-bells in hand, raising arms from hanging position to position illustrated.] [Illustration: EXERCISE NO. 12.--Reclining arms hanging, raising bells upward and outward from the body, level with shoulders. Reversing that motion by bringing bells from position illustrated in No. 11 to position on level with the shoulders, as illustrated in No. 12.] position to position illustrated. This exercise will strengthen the muscles of the neck and shoulders. If one has sustained some injury that threatens tetanus, or “lock-jaw” complications, the application of this exercise would often break the spell. “Keep moving your arms, keep moving your arms,” was Dr. Benjamin Rush’s constant advice to persons threatened with tetanic complications. =Exercise No. 12.=--Reclining with arm hanging, raise dumb-bells upward and outward from the body, level with shoulders. Reverse this motion by bringing bells, from position illustrated in No. 11, to position on level with shoulders, as illustrated in this exercise. In value and results this exercise is very much like No. 11. Consumptive microbes will have a poor chance to effect a lodging in a body getting the benefit of these exercises.
