Bodily exercise is in one sense a means of repair, inasmuch as it quickens the circulation and respiration, and makes the whole organism more active. The old maxim that Exercise strengthens every power must not be overlooked, as the arm of the rower or the wrist of the confirmed croquet-player will testify. But it must also be remembered, and this is a matter of prime importance, that it is only _judicious_ exercise which gives strength; and by judicious exercise is meant that in which the parts exercised are not too steadily on the strain, and that which is regular. For instance, continual standing in one spot is not judicious exercise for either man or woman, because the muscles whose contraction is required to maintain the body in an upright position, are kept for too long a time in a state of action; the continual tension prevents the free passage of the blood, and the uniformity of the circulation is destroyed. Continual standing, in the teaching profession at least, has broken down many a man as well as many a woman. With women, and especially with growing women, the danger is greater, resulting, of course, from the greater breadth of the pelvis and the less physical strength; and any woman who persists in it, simply exhibits an amount of recklessness which can be cured only by her own experience, and never by the advice of others.[6] If she had been better educated, she would know better and act more wisely. Secondly, exercise which is irregular or is used spasmodically, is not judicious. If, for instance, our girls had from their earliest childhood and during many months of the year, been accustomed to skating, no harm would probably result from it. But when, as was the case some twenty years ago, a sudden fashion sprang up for this exercise, and girls in all parts of the Northern States insisted upon learning to skate, with untrained muscles, and to skate for hours together during the freezing intervals of our uncertain climate, an immense amount of harm was actually done, the results of which multitudes of women in Boston and New York are to-day enduring.
