There remains one other prominent muscle below the knee, that in front, running down along the outer side of the shin-bone. Develop the calf fully, as is often done, and omit this little muscle and the work which calls it into play, and there is something wanting, something the lack of which causes a lack of symmetry. Fast walking, when one is unused to it, especially when the knees are held pretty straight, will work this muscle so vigorously as to make it sore. But a plain, safe, and simple exercise for it, yet one which, if protracted, will soon swell it into notice, and give it unwonted strength and beauty, is effected by stooping down as low as possible, the feet being but a few inches apart, and the heels never being allowed to rise even a quarter of an inch off the floor. Lift the heels, and this muscle is at once relieved. Laying any weight on the foot, and lifting it clear from the ground, will also call on this muscle. So will fastening the feet into straps, like those on a boat-stretcher or rowing-weight, and swaying the body of the sitter back and forth; for these muscles have heavy work to do to aid in pulling the body forward, so that the rower may reach his hands out over his toes for a new stroke. Simply standing on one foot, first holding the other clear of the floor, and then drawing it up as near as possible to the front of its own ankle, and then opening it as wide as you can, will be found a safe and reasonably effective way of bringing forward this small but useful muscle; while walking on the heels, with the toes drawn up high, is simpler yet. For those who want to run heavy risks, and are not contented with any exercise which does not threaten their necks, hanging by the toes from a horizontal or trapeze bar will be found to just fill the bill. _Work for the Front of the Thigh._ The muscles of the front thigh have a most intimate connection with those already mentioned, and, for ordinary purposes, a fair development of them is more necessary than of those below the knee. In common walking, for instance, while the calf gets something to do, the thigh gets far more, especially when the step is low and flat, and the heel never raised far from the ground. A man will often have large and strong thighs, and yet but indifferent calves. A prominent Harvard oarsman, a strong and fast walker, and a man of magnificent development in most points, was once examined carefully by Greenough, the sculptor. "I should know you were an American," said he, "because you have no calves;" and, indeed, his mistake in developing splendid arms, and trunk, and thighs, and forgetting all about the calves, is far too common a one among our athletes to-day; though the prominence they are beginning to give to running helps mend matters in this respect.
