swinging muscles and the standing muscles act and rest in alternate
rhythmic action, the chest is held high, the side muscles free to
move in, harmony with the legs, and all the spring in the body
brought into play through inclining slightly forward and pushing
with the ball of the back foot, the arms swinging naturally without
tension. Walking with a free body is often one of the best forms of
rest, and in the varying forms of motion arranged for practice we
are enabled to realize, that "perfect harmony of action in the
entire man invigorates every part."

MIND TRAINING





IT will be plainly seen that this training of the body is at the
same time a training of the mind, and indeed it is in essence a
training of the will. For as we think of it carefully and analyze it
to its fundamental principles, we realize that it might almost be
summed up as in itself a training of the will alone. That is
certainly what it leads to, and where it leads from.
