NOTE: the cover photo which is messed up here, is reproduced perfectly on the book.By far the best and most useful of Macfadden's numerous publications, this book, originally published in 1915, covers exercises in detail for developing vitality (physical well-being and energy). It also presents some excellent information about a healthful diet, correct breathing, fresh air, preserving the teeth, curing constipation, blood purification, bathing, clothing, sleep, etc. It covers a wide range of health subjects.The author, Bernarr Macfadden (1868-1955), was America's first "health guru" and definitely ahead of his time. This book presents many of his theories in a clear and readable format. The style of writing is dated, but his message is clear - his enthusiasm is obvious in just about every word. The photographs are numerous and excellent.
