back are free and under control. Of course the natural state of the
spine, as the seat of a great nervous centre, affects many muscles
of the body, and, on the other hand, the freedom of these muscles
reacts favorably upon the spine.

The legs are freed for standing and walking by shaking the foot free
from the ankle with the leg, swinging the fore leg from the upper
leg, and so freeing the muscles at the knee, and by standing on a
footstool and letting one leg hang off the stool a dead weight while
swinging it round from the hip. Greater freedom and ease of movement
can be gained by standing on the floor and swinging the leg from the
hip as high as possible. Be sure that the only effort for motion is
in the muscles of the hip. There are innumerable other motions to
free the legs, and often a great variety must be practised before
the freedom can be gained.

The muscles of the chest and waist are freed through a series of
motions, the result of which is shown in the ability to toss the
body lightly from the hips, as the head is tossed from the waist
muscles; and there follows the same gentle involuntary swing of the
muscles of the waist which surprises one so pleasantly in the neck
muscles after tossing the head, and gives a new realization of what
physical freedom is.

In tossing the body the motion must be successive, like running the
scale with the vertebrae.

In no motion should the muscles work _en masse._ The more perfect
the co-ordination of muscles in any movement, the more truly each
muscle holds its own individuality. This power of freedom in motion
