Here, then, we have a horizontal bar fitted for most of the uses of that valuable appliance, a pair of parallel bars, or their equivalent for certain purposes, a pair of pulling-weights, and a rowing-weight. Now, with the addition of a pair of dumb-bells, weighing at first about one twenty-fifth of the user's own weight, we have a gymnasium more comprehensive than most persons would imagine. Mr. Bryant was contented for forty years with less apparatus even than this, and yet look at the benefit he derived from it![D] The bar, cleats, and parallels ought to be made and put up for not over two dollars, and four or five dollars more will cover the cost of pulling-weights and gear on the old plan, unless a heavy rowing-weight is added, which can be had at five cents a pound, which is also the price of well-shaped dumb-bells. Here is a gymnasium, then, under cover, rent free, exactly at hand, when one is lightly clad on rising or just before retiring, which takes up but little room, can hardly get out of order, which will last a dozen years. With these few bits of apparatus every muscle of the trunk, nearly all those of the legs, and all those of the arms, can, by a few exercises so simple that they can be learned at a single trying, be brought into active play. The bar in the upper place will be useful mainly for grasping, hanging, or swinging on by the hands, or for pulling one's self up until the chin touches it. In the lower place it enables one to perform very many of the exercises usual on the horizontal bar. The short bars or handles have scarcely more than one office, but that is one of the most important of all exercises for the weak-armed and the weak-chested. This exercise is the one called "dipping." The bars are grasped with the hands, the feet being held up off the floor; then, starting with the elbows straight, gradually lowering until the elbows are bent as far as possible, then rising till they are straight again, and so continuing. The pulley-weights admit of a great variety of uses, reaching directly every muscle of the hand, wrist, arm, shoulder, chest, abdomen, the entire back and neck; while, by placing one foot in the handle and pulling the weight with it, several of the leg muscles soon have plenty to do, as is also the case with the rowing-weight. The field of the dumb-bells is hardly less extensive. If but one of these pieces of apparatus can be had, the pulley-weights are the most comprehensive, and so the most important, though it is astonishing how closely the dumb-bells follow; and then they have the great advantage of being portable. Combine with the exercises you can get from all this apparatus those which need none at all, such as rising on the toes, hopping, stooping low, walking, running, leaping, and no more tools are needed to develop whatever muscles one likes. What special work will employ any particular muscle will be indicated later.
