內容簡介 The war cry of to-day in peace no less than in war is for efficiency. We need stronger, more capable men; healthier, superior women. Force is supreme-the king of all mankind. And it is force that stands back of efficiency, for efficiency, first of all, means power. It comes from power, and power either comes directly from inheritance or it is developed by an intelligent application of the laws that control the culture of the physique. The value of efficiency is everywhere recognized. The great prizes of life come only to those who are efficient. Those who desire capacities of this sort must recognize the importance of a strong, enduring physique. The body must be developed completely, splendidly. The buoyancy, vivacity, energy, enthusiasm and ambition ordinarily associated with youth can be maintained through middle age and in some cases even to old age. If your efforts are to be crowned with the halo of success, they must be spurred on by the pulsating throbbing powers that accompany physical excellence. These truly extraordinary characteristics come without effort to but few of us, but they can be developed, attained and maintained.
