If still harder thigh-work is wanted, starting again, with the feet not over four inches apart, this time do not raise the heels at all, but stoop down slowly, as low as possible, bending the knees greatly, of course, the back, however, being held straight all the while. Then rise to an erect position, then go down again. Practising this three times each morning and afternoon at first, may be followed up with six a week later; and twelve by the end of the month. Better work than this for quickly giving size and strength to the thighs could hardly be devised; while, as has been already noted, scarcely any muscles on the whole body are more needed or used for ordinary walking. Still standing erect, with arms akimbo, raise the right foot in front about as high as the left knee, keeping the right knee unbent. Hold the right foot there ten seconds; then drop it; then raise it again, fully six times. Then, standing, do the same thing with the left foot. This calls at once on the muscles across the abdomen, aiding the stomach and other vital organs there directly in their work. This time raise the foot equally high behind; then return it to the floor and so continue, giving each foot equal work to do. The under thigh, hip, and loin are now in action; and when, later on, they become strong, their owner will find how much easier it is to run than it used to be, and also that it has become more natural to stand erect. The rate of increase of these last two exercises may be about the same as the others. There is not much left now of the ten minutes. Still, if the work has been pushed promptly forward, there may still be a little time. However, all three of the kinds of work suggested for the front thigh need not be practised at the one recess, any one sufficing at first. With head and neck again erect, and knees firm, hold the hands out at the sides and at arm's-length, and clasp the hands firmly together, as though trying to squeeze a rubber ball or other elastic substance. Beginning with twenty of these movements, fifty may be accomplished by the end of the fortnight; and by their continuance both the grip and the shape of the hand will be found steadily improving. Clasp the hands together over the head. Now turn them over until the palms are upward, or turned toward the ceiling, and straighten the elbows until the hands are as high over the head as you can reach. While holding them in this position, be careful that they are not allowed to drop at all. Let the scholar march three or four times around the room in this position. It will soon be found that no apparatus whatever is necessary to get quite a large amount of exercise for the corners of the shoulders. In this way, while there is an unwonted stretching apart of the ribs, and opening up of the chest, the drawing in of the stomach and abdomen will be found to correct incipient chest weakness, half-breathing, and any tendency toward indigestion.
