Another question which pupils are constantly asking me is whether it is right for them to perspire after the exercises. The answer to this question is that it depends on the constitution of the pupil. If you perspire, it does you good; if you do not it shows that your condition is sound already. Of course it will be understood that I am answering in this, as in other questions, for general cases. There are always exceptions. Again, “What,” it is asked, “are the general benefits of the Sandow system of physical training?” The benefits are not, of course, confined to the visible muscular development. The inner organs of the body also share them. The liver and kidneys are kept in good order, the heart and nerves are strengthened, the brain and energy are braced up. The body, in fact, like a child, wants to be educated, and only through a series of exercises can this education be given. By its aid the whole body is developed and, as will be seen, pupils who have conscientiously worked at my system testify freely to the good results obtained, not only in the direction of vastly increasing their muscular strength, but of raising the standard of their vitality and general health. For the beginner the most difficult part of my system is so fully to concentrate his mind on his muscles as to get them absolutely under control. It will be found, however, that this control comes by degrees. The brain sends a message to the muscles; the nerves receive it, and pass it on to them. With regard to the will power that is exerted it should be remembered that whilst the effect of weight lifting is to contract the muscles, the same effect is produced by merely contracting the muscles without lifting the weight. This question of “will power” has, I am aware, troubled a good many of my pupils. The majority find it difficult to “put all they know” into movements with small dumb-bells, and consequently are apt to be disappointed at the results of their work. Not infrequently I have received a letter stating that the writer is doing the exercises an immense number of times, occupying several hours a day--three or four or even more!--and yet does not find that there is very much improvement. The reason is obvious; he is simply “going through” the motions and not really working at them. On the other hand, here and there, I come across a man possessing an amount of will power out of all proportion to his strength. The consequence is that he soon gets exhausted, and either cannot get through his exercises or only does so at the cost of becoming thoroughly done up and jaded. The great rule that progress in the direction of the exertion of will power should be gradual and ever continuing, is one that many people confess they are unable to carry out.
