Now remember that all real muscular power originates in the nervous system and brain. If the nervous system and brain are not in perfect condition, the full power of the muscles can never be utilized any more than you can get the full power out of your big car if the cylinders are too small or so weak in construction that you do not dare to run them at full speed.
This is one reason why men born with big frames and large muscles are not always the strong men. Frequently these men break down in the prime of life. Also during their active lives they really never get all their power in use. I consider such men unfortunate in that they do not possess the knowledge of their condition, so they neglect in early life the necessary rules and habits which, if heeded would bring them to old age in full possession of their natural strength.
The weakling who realizes his failings and knows how to correct and care for them, is more often the strong and healthy man in middle and later life. This fact teaches us one of the great laws of nature; that is that we cannot for a day neglect our body; the born strong man does, he never watches or cleans his big machine—it goes to rust and wears out in parts.
These strong men as youths, from the mere fact of having big, hawser-like muscles controlled by a slow-moving force, do not have the incentive to build up active muscles nor the energy to train the nervous mechanism controlling muscular activity. The result is that such a man’s muscles remain coarse fibered, fatty, bulky, and respond slowly to the motor centers of the brain. Moreover, they feel in such perfect health that they are careless about their habits and throw away a lot of energy that the man who is building up strength takes care of—saves for future use and material.
A youth who desires to build muscular strength goes about it carefully and slowly. Remember that all staying powers, brain or muscle, must be built up slowly. The tough and hardy oak does not grow like the weak poplar—quickly. Its growth is steady, regular and slow, but in the end it is powerful, long lived and richly reproductive. Make haste slowly is one of the fundamental laws of nature.
Brain and nervous system always come first in starting to build muscular power that is to last and be always at your command. The basis of power depends upon the rapidity with which the muscles respond to mental impulses. Properly developed muscles are finely-fibered, and react instantly to the impulse of the motor cells of the brain—the cells which tell the muscles to shoot out at once. Now let anything such as alcohol, tobacco, loss of sleep or immoral habits, fasten on the youth and all attempts to get the full strength out of muscles, no matter how big they are, will be useless. The reason is that the brain cells have been affected—they cannot act as they should and so the muscles cannot respond to the impulse. This is the cause of so many first-class boxers taking the final count. Success has made them careless; they neglect the rules of the physiologic game, they drink a little, smoke and indulge in other habits which affect their nervous system. They go on the stage breathing the foul and poisonous atmosphere while exhibiting, are necessarily late to bed and while still keeping up their MUSCULAR training neglect the fact that every day they are injuring their nervous motility. It is so little noticed that no attention is paid to the matter. But when it comes to a battle after such a career—even if careful training has been done weeks before the contest—the effect is shown, and down the champion goes before a less experienced boxer, one not so strong in the muscles but one whose full brain and nervous force has remained uncontaminated. Then, sad to relate, THIS champion goes the same way.
So you see that mere gross muscular structure is valueless—except it is needed for daily labor, where it exists as mere animal automatism—unless it is under the immediate control of a highly-organized nervous system free from disease and abuse.
So delicate is this nervous element of the body in getting the muscles to respond, that I have tested hundreds of athletes—including myself—by a very sensitive instrument which shows the response of the muscles to the condition of the brain cells. A youth who has lived a perfect life—physiologically speaking—is kept from one half of his night’s sleep. The next day he is tested and there is a difference shown in the rapidity of muscular response. The difference in a tenth of a second in a blow makes all the difference between a champion and a loser, and this tenth of a second can be brought about by the loss of one night’s rest. How must it be then when the youth has lost several, or been breathing foul air with heavily working lungs?
The extreme muscular development seen in those who pose on the stage and before the camera, while marvelous to the sight, is in reality of little practical use. Such muscles are not developed through normal exercises, but gain their prominence by being contracted and expanded through mental concentration on the muscle itself, not on any work that the muscle should be made to perform. Under this fad form of “physical culture” the levers which the muscles should lift and lower are kept immovable, the muscles themselves do no work, the fibers only being caused to swell and shrink.
Take the “development” of the biceps, for instance. This muscle is intended to flex the forearm, attachments being on the upper arm and shoulder and the insertions in the upper part of the lower arm, making a perfect leverage. Now, in this false “physical culture” system the arm is held semi-flexed and rigid and the muscle made to rise and fall, no tension being put upon its attachments. The result is a development of the center of the muscle, but a development of a mere shape, not the development of the power of lifting. The attachments are not developed or strengthened; they remain thin; hence, to the spectator in the audience, the center of the bulking mass of biceps looms up as a powerful organ of force—it is simply an artificial lump.
