The maintenance of every muscle of the body in proportionate development is regulated by its work as well as by its supply of pabulum, although the latter is determined in large part by the necessity for repair or upbuilding occasioned by the exercise given the particular muscle. Constant use of one portion of the muscular fabric tends to add to its substance at the expense of that of neighboring parts not equally exercised. Hence the aim of all physical labor should be that of uniformity. Trunk and legs, arms and neck, all should receive proportioned attention. Normal muscular development also depends upon an unimpeded circulation of the blood and upon healthful cell-forming constituents uninterruptedly supplied for the replacement of used tissue. Constriction of the body in any region restricts free circulation, and only loose garments permit of full growth and proper development. The tight collar, the round garter, and the corset, make flabby muscles inevitable, and only a body unrestrained by the bonds so often prescribed by conventional usage can hope for muscular perfection. The possibilities of hygienic living, coupled with judicious exercise, are surely worth consideration, if merely for the satisfaction resulting from their effects upon personal appearance; but their more important consequences in respect to general health and longevity make neglect of these desiderata most deplorable.

Exercise that is self-imposed is wholesome; but exercise to which one is naturally attracted is the ideal form of labor. Combined with enthusiasm, physical work is doubly healthful, for enthusiasm in itself is a source of health. And that form of exercise that serves a productive purpose and is enthusiastically performed is best of all, whether the effort be physical or mental. Make your avocation the complement of your vocation. Gladstone and Horace Greeley chopped wood in their moments of relief from mental tasks. Conversely he who works with his hands should divert himself by exercising his brain.

During a fast moderate exercise in keeping with daily access of strength is advised, and, after the completion of the period of abstinence, constant comprehensive muscular activity is essential to tissue rebuilding and to form-development and maintenance.
