If, then, vitality be our aim in physical training, and not muscularity as such, nor in any degree except in so far as it serves vitality, it is plain that we shall to some extent reconsider our methods. Pre-eminently will this apply to the girl. Just because she is now becoming a woman, her vital energies are in no small degree pledged for special purposes of the highest importance, from which we cannot possibly divert them if we desire that she shall indeed become a woman. Thus, though muscular exercise of any kind is certainly not to be condemned, we must be cautious; for, in the first place, muscular exercise is no end in itself; in the second, the production of big muscles by exercise is no end in itself; and in the third place, all muscular exercise is expenditure of energy in those outward directions which are not characteristic of womanhood, and which must always be subordinated to those interests that are. At this period of which we are speaking there are constructions of the most important kind going on in the girl's body, compared with which the construction of additional muscular tissue is of much less than no importance. These building-up processes are, we know, characteristic of the woman. Their right inception is a matter of the greatest importance. They involve the actual accumulation of food material and the building up of it into gland cells and other highly organized tissues upon which complete womanhood depends. These all-important concerns are prejudiced by excessive external expenditure, and thus the care necessary for the boy at puberty is a thousandfold more necessary for the girl, though the obvious changes in her appearance and her voice may be much less marked. Greater and more costly constructions are afoot in her case than her brother's, grossly though these facts are at present ignored in what we are pleased to call education, both physical and mental. If we are to decide what kinds of physical exercise will be most desirable, we must come to some conclusion as to what is the object of our labours, it being granted that muscular activity and the making of big muscles are not ends in themselves. The answer to this question is to be found in what I have elsewhere called the new asceticism.
