Zander machines. Realizing that certain activities are sufficiently or
too much emphasized in ordinary life, stress is laid upon those which
are complemental to them, so that there is no pretense of taking
charge of the totality of motor processes, the intention being
principally to supplement deficiencies, to insure men against being
warped, distorted, or deformed by their work in life, to compensate
specialties and perform more exactly what recreation to some extent
aims at.

This wholesome but less inspiring endeavor, which combats one of the
greatest evils that under modern civilization threatens man's physical
weal, is in some respects as easy and practical as it is useful. The
great majority of city bred men, as well as all students, are prone to
deleterious effects from too much sitting; and indeed there is
anatomical evidence in the structure of the tissues, and especially
the blood-vessels of the groins, that, at his best, man is not yet
entirely adjusted to the upright position. So a method that
straightens knees, hips, spine, and shoulders, or combats the
school-desk attitude, is a most salutary contribution to a great and
growing need. In the very act of stretching, and perhaps yawning, for
which much is to be said, nature itself suggests such correctives and
preventives. To save men from being victims of their occupations is
often to add a better and larger half to their motor development. The
danger of the system, which now best represents this ideal, is
inflexibility and overscholastic treatment. It needs a great range of
individual variations if it would do more than increase circulation,
respiration, and health, or the normal functions of internal organs
and fundamental physiological activities. To clothe the frame with
honest muscles that are faithful servants of the will adds not only
strength, more active habits and efficiency, but health; and in its
