Jumping
Of all the corporeal exercises jumping is one of the most useful; and during our lives very many instances occur of a good jump having done us essential service. To jump with grace and assurance one should always fall on the toes, taking care especially to bend the knees on the hips: the upper part of the body should be inclined forwards, and the arms extended towards the ground. The hands should serve to break the fall when jumping from a great height. In jumping we should hold the breath and never alight on the heels. Boys should exercise themselves in jumping, by jumping in length, and jumping from a height, with attention to the above cautions. They may make progressive exercises in length by varying the distance from time to time, and in height by jumping from a flight of stairs or steps, increasing a step at a time: they will soon be able to jump in length three yards, and from a height six feet, without injury.
