Now this list of fourteen exercises which we have extracted from a much larger number will, we believe, be found sufficient to exercise in a healthy and reasonable manner a very large proportion of the muscles of the body. They may seem, especially to anyone who has been accustomed to long exercises with heavy dumb-bells, mere child’s play, but if they are given a trial, and especially if the utmost rapidity is used in making those movements where

rapidity is enjoined, they will, we think, be found not unsatisfactory. Those people who are accustomed to gauge their exercise by the fatigue which it produces may not, it is true, be pleased with them, but for our part we do not for a moment believe that fatigue is any criterion of satisfactory exercise. It is perfectly easy to fatigue oneself in a very few minutes by unsuitable exercises, just as it is easy for a man accustomed to walk rapidly to feel real sensations of fatigue if he has to walk very slowly for half an hour. Yet no one would say that he had therefore enjoyed more satisfactory exercise. For to use a muscle wrongly is in itself fatiguing, and for this reason exercises of the muscles of the arms should be far more rapid than exercises for the legs, and exercises for the legs in the same way more rapid than those for the chest and abdomen. It would be out of the question to try to make the breathing muscles exercise themselves with the rapidity that is easy to the muscles of the ankle, and in the same way it is useless to exercise the muscles of the wrist only as fast as it is reasonable to exercise the muscles of the abdomen. They are adapted for widely different purposes; use then each for its own.
The advantage which we claim for such exercises is that they give exercise and do not produce fatigue. Furthermore, they take far less time than ordinary courses of dumb-bell exercise, they require no apparatus whatever, they produce briskness of movement, and will keep the muscles in better condition for games and athletics than do mere slow strength-producing movements. But we should not for a moment urge a man who played games regularly to use at any rate all these exercises on those days when he is playing, for it is certain that some muscles, if not all, will be quite sufficiently exercised by the game, and thus it is mere waste of time on his part, and unnecessary expenditure of energy to add to that which is already sufficient. On the other hand, most games—at any rate as they are played by most people—will not exercise all the muscles which even this list covers, and a man might with advantage exercise those by these means.
With regard to the increase in the number of times each exercise is done, it is quite impossible to lay down any general rule, since anyone whose muscles are already accustomed to rapid movement will be able to increase the exercise more quickly than one who is not; but as a general guide for everyone it may be said that none of the exercises should be repeated more than once or twice after the least feeling of fatigue or aching begins. But far more important than mere repetition is the rapidity of movement with which one does those that are meant to be rapid, and it is infinitely better to do such exercises only half the number of times suggested, with concentration and speed, than twice the number if they are done slackly or not fully. The first essentials are to do them correctly and rapidly; the endurance and strength to repeat them many times with correctness and rapidity will come of their own accord. But the correctness is also a sine quâ non: for it is the intelligent and faithful obedience of the body to the will which is no less an object of exercise than the efficiency of the body considered by itself, and just as to practise these exercises correctly is the foundation of a good habit, so to practise them incorrectly is the foundation of a bad one.
For athletes, then, we believe that they will help in a marked degree to keep the muscles in good tone when there is forced on them a period of inaction from games. This effect would not be obtainable from dumb-bell exercises, since the latter for the most part are slow movements which are not of the least good as practice for games, but (though undoubtedly strength-giving) if used alone rather prejudicial to speed than otherwise. And for non-athletic people and athletes alike, they will help to keep the body in good health, not only because, for reasons given above, exercise is healthy, but because many of them are specially devoted to using those large muscle-areas of the body on which the proper daily working of the system depends, and these are exercised without risk of straining, whereas to exercise them with heavy dumb-bells in the hands has before now produced, and will again produce, injury. Furthermore, the body is far less liable to be attacked by definite disease if it is in a healthy condition, while also the daily hardening which it will experience in the system of exposure which we recommend, will render it considerably less prone to catch cold by reason of draughts or change of temperatures, which otherwise are often the immediate causes of chill.
Now, though games are more to be recommended than mere exercise for those who can afford the time and money for them, inasmuch as the enjoyment derived from them is greater (the benefit derived being therefore greater),[3] and all sorts of qualities are called out, which mere exercises do not demand, it must not be supposed that all games (or for that matter all exercises) are suitable to all ages and constitutions. For in the human body speed (as in these exercises) is naturally developed before strength, and a lad of twenty will beat a man of forty in a hundred yards’ race, though he has not nearly the same amount of pure physical force at his disposal. Short and violent exercises, exercises demanding top speed, or a swift stroke, are natural to youth, and, broadly speaking, as with advancing years (even though a man is still in his prime) strength increases, speed somewhat diminishes. Thus, though exercise and exercises are quite undoubtedly good for a young boy, it seems by the example of nature herself, that exercises demanding strength and continued effort are bad. Thus for children we should never recommend dumb-bell or developer exercises at all, except with weights and resistances so small that they practically call forth no extra strength to manipulate, but which serve in so far as the hand is occupied to fix the child’s attention on what he is doing. Even in later years strength, or at any rate that sort of strength which is measured and accompanied by very bulky muscles, not only does not assist, but even hinders speed of any movement; and though a certain amount of strength is required for movement of any kind, it is (though it is possible not to have enough) also possible to have too much of the wrong sort. Of course, if a man’s physical ambition is limited to weight-lifting, there is nothing more to be said: let him continually lift weights. But if it is in the direction either of good health or athletic excellence, we think he can do better than practise habitually with dumb-bells, or “grips,” or other strain-producing apparatus.
