CONSTRUCTIVE EXERCISES
Constructive period of life from ages 15 to 25
Constructive exercises should be taken and practised regularly between the ages fifteen and twenty-five. It is largely during this period that the physical condition of the body for the balance of life is determined.
Poisoning and purifying the blood
Many a college youth, endowed by Nature with a sound physical body and a healthy brain, has irreparably injured both by sitting on the end of his spine with his feet higher than his head, poisoning his blood with tobacco narcotics from a stylish pipe and failing to keep it purified by obeying the laws of motion and of oxidation. Constructive exercises should employ every muscle in the body long enough once in every twenty-four hours to generate sufficient heat to cause perspiration, or at least to force twice the normal quantity of blood to the lungs for purification. Exercise thus taken up to the point of fatigue, and of sufficient duration to use all the nutrition taken in the form of food, will, under favorable conditions, build the body to its highest degree of physical strength, provided we keep Nature supplied with the right kind of material (food) with which to do her work.
