Many lean persons, impressed with the apparent discomfort and inconvenience of obesity, are content with their slender measure of flesh. This is especially true of men, who, as a rule, have less regard for beauty of form than those of the other sex. They overlook the fact that the man whose bony structure is well overlaid with thick layers of healthy muscular tissue is able not only to accomplish more work, but to stand greater exposure and endure more hardships than the lean man. His stronger, heavier muscles will not only carry his greater weight with less effort, but his larger body will possess a momentum that the other man does not have. In the severe training preceding the inter-collegiate boat races, while the over fleshy lose their superfluous fat, the thin gain as rapidly in weight. Many lean people whose occupations are of a physical nature do too much, daily, in proportion to their strength. Mind and body are kept in such a constant state of activity that their energies become exhausted. If such persons will take an occasional rest through the day, when it is possible so to do, and will add an hour or more to the period of sleep, their weight will soon begin to increase. Then, by special exercises aimed at the weak points, and persistently sustained, the gain in weight will be that of solid, healthy, muscular tissue, which will not only fill out their leanness, but will give them power to do more work with less fatigue. A short rest after meals, with the practice of deep abdominal breathing, begun, if need be, as a special drill, but ultimately established as a habit, will go far toward improving the digestion and converting the food into good, healthy blood, so indispensable to the growth of every part of the human body. =Exercises for Gouty and Rheumatic Persons.=--Gout and other uric acid conditions, whether hereditary or acquired, frequently yield to systematic physical exercises. These conditions are generally the result of indigestion or overfeeding. By exercise, more oxygen is brought into the circulation of the blood, and the chemical process is promoted. By free perspiration, the action of the skin is stimulated, and the work of the kidneys is lightened. In the case of those afflicted with gout, special care is needed for a time. A mild form of exercise should be employed at first, and gradually increased. A free perspiration should be induced daily, followed by a bath and vigorous rubbing. =Exercises for the Dyspeptic.=--If the system has become much weakened by dyspepsia or indigestion, begin with mild forms of exercise--walking, bicycling, golf, and other out-door sports. For a lack of tone of the abdominal muscles, swimming in warm weather is found useful. The in-door tank is not quite so good as the stream or surf. If the liver is chiefly at fault, horseback riding is a capital remedy. Gradually introduce more vigorous exercises. Daily bathing and rubbing must not be neglected.
