In writing this book I have taken it as a commonplace that everyone—man, woman, and child—wants to be strong. Without strength—and by strength I mean health, vitality, and a general sense of physical well-being—life is but a gloomy business. Wealth, talent, ambition, the love and affection of friends, the pleasure derived from doing good to those about one, all these things may afford some consolation for being deprived of life’s chief blessing, but they can never make up for it. “But,” I am constantly being asked, “it is all very well for you to say this, and everyone of sense agrees with you; the point is, can we obtain this much-prized blessing?” In the vast majority of cases I can say unhesitatingly “Yes.” You can all be strong, all enjoy the heritage which was intended for you. Not all to the same extent, perhaps. Those who are afflicted with some hereditary disease, who may have unsound organs handed down to them, cannot reasonably expect to get such results as their more fortunate brethren. Still, even they need not despair; even if their condition be such as to put out of the question any such thing as athletics, they can, at all events, attain to such a condition as will permit of their enjoying life, and render them fit to carry on their work without difficulty. And after all, those who wish to be strong for this reason are innumerable. It is only the young and vigorous who desire to excel in athletic pastimes, but the middle-aged and elderly, the delicate women and young children, who yearn for health are countless. I claim that by carefully following out my system, as set out in the following pages, and fully illustrated in the Anatomical Chart at the end of the volume, these results may be attained.
