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.
