"IN every new movement, in every unknown attitude needed in difficult exercises, the nerve centres have to exercise a kind of selection of the muscles, bringing into action those which favor the movement, and suppressing those which oppose it." This very evident truth Dr. Lagrange gives us in his valuable book on the Physiology of Exercise. At first, every new movement is unknown; and, owing to inherited and personal contractions, almost from the earliest movement in a child's learning to walk to the most complicated action of our daily lives, the nerve centres exercise a mistaken selection of muscles,—not only selecting more muscles than are needed for perfect co-ordination of movement, but throwing more force than necessary into the muscles selected. To a gradually increasing extent, the contracting force, instead of being withdrawn when the muscle is inactive, remains; and, as we have already seen, an arm or leg that should be passive is lifted, and the muscles are found to be contracted as if for severe action. To the surprise of the owner the contraction cannot be at once removed. Help for this habitual contraction is given in the preceding chapter. Further on Dr. Lagrange tells us that "Besides the apprenticeship of movements which are unknown, there is the improvement of already known movements." When the work of mistaken selection of muscles has gone on for years, the "improvement of already known movements," from the simplest domestic action to the accomplishment of very great purposes, is a study in itself. One must learn first to be a grown baby, and, as we have already seen, gain the exquisite passiveness of a baby; then one must learn to walk and to move by a natural process of selection, which, thanks to the contractions of his various ancestors, was not the process used for his original movements. This learning to live all over again is neither so frightful nor so difficult as it sounds. Having gained the passive state described in the last chapter, one is vastly more sensitive to unnecessary tension; and it seems often as though the child in us asserted itself, rising with alacrity to claim its right of natural movement, and with a new sense of freedom in the power gained to shun inherited and personal contractions. Certainly it is a fact that freedom of movement is gained through shunning the contractions. And this should always be kept in mind to avoid the self-consciousness and harm which come from a studied movement, not to mention the very disagreeable impression such movements give to all who appreciate their artificiality.

Motion in the human body, as well as music, is an art. An artist has very aptly said that we should so move that if every muscle struck a note, only harmony would result. Were it so the harmony would be most exquisite, for the instrument is Nature's own. We see how far we are from a realization of natural movement when we watch carefully and note the muscular discords evident to our eyes at all times. Even the average ballet dancing, which is supposed to be the perfection of artistic movement, is merely a series of pirouettes and gymnastic contortions, with the theatrical smile of a pretty woman to throw the glare of a calcium light over the imperfections and dazzle us. The average ballet girl is not adequately trained, from the natural and artistic standpoint. If this is the case in what should be the quintessence of natural, and so of artistic movement, it is to a great degree owing to the absolute carelessness in the selection of the muscles to be used in every movement of daily life.

Many exercises which lead to the freedom of the body are well known in the letter—not in the spirit—through the so-called "Delsarte system." if they had been followed with a broad appreciation of what they were meant for and what they could lead to, before now students would have realized to a far greater extent what power is possible to the human body. But so much that is good and helpful in the "Delsarte system" has been misused, and so much of what is thoroughly artificial and unhealthy has been mixed with the useful, that one hesitates now to mention Delsarte. Either he was a wonderful genius whose thoughts and discoveries have been sadly perverted, or the inconsistencies of his teachings were great enough to limit the true power which certainly can be found in much that he has left us.

Besides the exercises already described there are many others, suited to individual needs, for gaining the freedom of each part of the body and of the body as a whole.

It is not possible to describe them clearly enough to allow them to be followed without a teacher, and to secure the desired result. Indeed, there would be danger of unpleasant results from misunderstanding. The object is so to stand that our muscles hold us, with the natural balance given them, instead of trying, as most of us do, to hold our muscles. In moving to gain this natural equilibrium we allow our muscles to carry us forward, and when they have contracted as far as is possible for one set, the antagonizing muscles carry us back. So it is with the side-to-side poising from the ankles, and the circular motion, which is a natural swinging of the muscles to find their centre of equilibrium, having once been started out of it. To stand for a moment and think the feet heavy is a great help in gaining the natural poising motions, but care should always be taken to hold the chest well up. Indeed, we need have no sense of effort in standing, except in raising the chest,—and that must be as if it were pulled up outside by a button in its centre, but there must be no strain in the effort.

The result of the exercises taken to free the head is shown in the power to toss the head lightly and easily, with the waist muscles, from a dropped forward to an erect position. The head shows its freedom then by the gentle swing of the neck muscles, which is entirely involuntary and comes from the impetus given them in tossing the head.

Tension in the muscles of the neck is often very difficult to overcome; because, among other reasons, the sensations coming from certain forms of nervous over-strain are very commonly referred to the region of the base of the brain. It is not unusual to find the back of the neck rigid in extreme tension, and whether the strain is very severe or not, great care must be taken to free it by slow degrees, and the motions should at first be practised only a few minutes at a time. I can hardly warn readers too often against the possibility of an unpleasant reaction, if the relaxing is practised too long, or gained too rapidly.

Then should come exercises for freeing the arms; and these can be taken sitting. Let the arms hang heavily at the sides; raise one arm slowly, feeling the weight more and more distinctly, and only contracting the shoulder muscles. It is well to raise it a few inches, then drop it heavily and try again,—each time taking force out of the lower muscles by thinking the arm heavy, and the motive power in the shoulder. If the arm itself can rest heavily on some one's hand while you are still raising it from the shoulder, that proves that you have succeeded in withdrawing the useless tension. Most arms feel stiff all the way along, when the owners raise them. Your arm must be raised until high overhead, the hand hanging from the wrist and dropped into your lap or down at the side, letting the elbow "give," so that the upper arm drops first, and then the fore arm and hand,—like three heavy sand-bags sewed together. The arm can be brought up to the level of the shoulder, and then round in front and dropped. To prove its freedom, toss it with the shoulder muscles from the side into the lap. Watch carefully that the arm itself has no more tension than if it were a sand-bag hung at the side, and could only be moved by the shoulder. After practising this two or three times so that the arms are relaxed enough to make you more sensitive to tension, one hundred times a day you will find your arms held rigidly, while you are listening or talking or walking. Every day you will grow more sensitive to the useless tension, and every day gain new power to drop it. This is wherein the real practice comes. An hour or two hours a day of relaxing exercises will amount to nothing if at the same time we are not careful to use the freedom gained, and to do everything more naturally. It is often said, "But I cannot waste time watching all day to see if I am using too much force." There is no need to watch; having once started in the right direction, if you drop useless muscular contraction every time you notice it, that is enough. It will be as natural to do that as for a musician to correct a discord which he has inadvertently made on the piano.

There are no motions so quieting, so helpful in the general freeing of the body, as the motions of the spine. There are no motions more difficult to describe, or which should be more carefully directed. The habitual rigidity of the spine, as compared with its possible freedom, is more noticeable in training, of course, than is that of any other part of the body. Each vertebra should be so distinctly independent of every other, as to make the spine as smoothly jointed as the toy snakes, which, when we hold the tip of the tail in our fingers, curve in all directions. Most of us have spinal columns that more or less resemble ramrods. It is a surprise and delight to find what can be accomplished, when the muscles of the spine and 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.
