esson should begin with the less violent exercises, gradually
working up to those that are more so, then gradually working back to
the simpler ones, so that the men at the close of the drill will be in
as nearly a normal condition as possible.

When one portion of the body is being exercised, care should be taken
that the other parts remain quiet as far as the conformation of the
body will allow. The men must learn to exercise any one part of the
body independent of the other part.

Everything in connection with physical training should be such that
the men look forward to it with pleasure, not with dread, for the mind
exerts more influence over the human body than all the gymnastic
paraphernalia that was ever invented.

Exercise should be carried on as much as possible in the open air; at
all times in pure, dry air.

Never exercise the men to the point of exhaustion. If there is
evidence of panting, faintness, fatigue, or pain, the exercise should
be stopped at once, for it is nature's way of saying "too much."

By constant practice the men should learn to breathe slowly through
the nostrils during all exercises, especially running.

A fundamental condition of exercise is unimpeded respiration. Proper
breathing should always be insisted upon; "holding the breath" and
breathing only when it can no longer be held is injurious. Every
exercise should be accompanied by an unimpeded and, if possible, by an
uninterrupted act of respiration, the inspiration and respiration of
which depends to a great extent upon the nature of the exercise.
Inhalation should always accompany that part of an exercise which
tends to elevate and distend the thorax--as raising arms over head
laterally, for instance; while that part of an exercise which exerts a
pressure against the walls of the chest should be accompanied by
exhalation, as for example, lowering arms laterally from shoulders or
overhead.

If after exercising, the breathing becomes labored and distressed, it
is an unmistakable sign that the work has been excessive. Such
excessiveness is not infrequently the cause of serious injury to the
heart and lungs or to both. In cases where exercise produces
palpitation, labored respiration, etc., it is advisable to recommend
absolute rest, or to order the execution of such exercises as will
relieve the oppressed and overtaxed organ. Leg exercises slowly
executed will afford great relief. By drawing the blood from the upper
