Finally, the personal equation is not sufficiently considered in any system of exercise that has come across our notice. There is Chart I. for children, Chart II. for boys between 14 and 18, Chart III. for adults. Any system of weight-moving, such as dumb-bells, will never satisfactorily fill such a need as here exists, unless the teacher will see and examine personally (provided also he has the requisite knowledge) each one of his pupils. A thick-set boy of fifteen, though he weighs the same as a tall lanky boy of the same age, requires a perfectly different set of exercises to produce in him fit and robust manhood, while the tall lanky boy may be injured by exercises that are good for the average boy of his age and weight. But that there are exercises which are practically good for everybody we fully believe. Of this we treat later. Again, for people who wish to excel at games, to begin with dumb-bells seems a mistake, for it teaches first the slow movement, whereas speed of movement should come first. That they give bulk to the muscles is undeniable, and there is a great deal to be said for bulk, if only it has the power of speed. In any case these dumb-bell and developer exercises should be alternated with quick, full movements, so as to preserve the speed of the action of the muscles. Now most people who feel the need of, and are better for, regular exercise are accustomed, when they have leisure and opportunity, to play some sort of game; and how enormously this tendency is increasing is shown, to take one instance alone, by the huge number of golf links which have sprung up all over the kingdom, and in particular round and close to London, accessible to the city man in summer for a short round perhaps when he returns home in the evening, and certainly used by him on Saturday afternoon and probably Sunday. He does not, as a matter of fact, hurry home in order to practise his beloved dumb-bells, he is not late for dinner because he cannot leave his dumb-bells, but because he will finish his round at golf. A game, in fact, is more enjoyed by most people than mere exercise for the sake of exercise. The dumb-bells are used when a game is not to be had. But these dumb-bell exercises, as we have pointed out, do not, except in so far as they may strengthen an inordinately weak muscle, improve or help a man’s game, unless we consider weight-lifting a game. Six months’ continuous exercise of the slow pushing and pulling order to overcome the inertia of the dumb-bell or the contraction of india-rubber will probably not lengthen his drive, since they do not teach speed of movement. That the long driver at golf may be very strong is beyond question, but it is equally beyond question that the professional strong man will incessantly be out-driven by a player whose muscles are half the size of the other’s, because the latter has cultivated swiftness of movement, the former has not. It is
