After a great deal of study a system has been devised which answers the needs in both cases; it is not too strenuous for the older men, and it will add suppleness, vitality, and endurance to the physical assets of the younger men.
A MODERN PHYSICAL SYSTEM We know how, in the stress of affairs brought about by war, not only individuals, but nations are suddenly awakened to the fact that what may have been good enough even a year ago is antiquated and out of date to-day.

Under the pressure of war we are driven, whether we wish it or not, to put to immediate test virtually every fact of our daily lives.
We find that almost every machine and well-nigh every method may be improved--in fact, that it must be improved.
Boats, aeroplanes, guns, industrial processes, even the actual business of living itself, all are being submitted to the test of emergency and are being made over upon new lines.

So it is with our setting-up exercises.

We can no longer afford to waste time or motion or effort.

We are teaching on an intensive scale and we must take nothing out of a man in preparation; rather we must add to his store of vitality and energy.
Perhaps we find that the routine of his ordinary work will strengthen sufficiently his legs and arms.
