Good, stiff long-distance walking is excellent for the front thigh; but running is better, especially when done as it ought to be, namely, not flat-footed, but with the heel never touching the ground. Any sort of running or walking, at any pace protracted enough to bring moderately tired muscles, will tell, especially on these in question; while severe work over a long distance will give them a great task, and the consequent ability and size. Many a man may do a little desultory running daily, perhaps for a week or two together once a year, and not find his thighs enlarge or toughen materially. But let him put in a few minutes each day, for several months together, at steady smart running, as far as he can, and go comfortably, and now, besides the work becoming easy, comes the desired size and strength as well. The hopping, which was so good for the calves, is hardly less so for these muscles, and is one of the best possible movements to develop them in the shortest time. Dancing, long continued, also tells here, as an acquaintance of ours found, who used to lead the German frequently at Newport; for, though far from being an athlete, he said that he daily ran a mile during the season, just to keep his legs in good order for the duties his position demanded. A more moderate exercise than the running, though not always so available, is walking uphill. This, besides, as already mentioned, doing so much for the calves, tells directly and markedly on the thighs as well. Skating makes a pleasant substitute for walking during a part of the colder months, and, when much distance is covered daily, brings strong and shapely thighs. The farmer and the laboring man, in all their heavier work done stooping over their tasks--such as lifting, shovelling, picking, and mowing--use the thighs much, but keep them so long fixed in one position, with little or no varying exercise to supple and limber them and the joints, that both gradually stiffen, and their instep soon begins to lack elasticity, which tendency is too often increased by heavy, stiff, and unwieldy boots. Swinging forward when rowing, either in a boat or at the toe-straps, after first swinging far back, takes these upper muscles in a way quite the reverse of their ordinary use, they now aiding to pull the whole trunk forward, and so acting like two long hooks. All lifting of heavy objects from the ground, standing in almost any position, tells heavily on these muscles, being about the severest momentary test they can have, greater even than in jumping. But occasional heavy lifting tends rather to harden the muscle than to rapidly increase its size, protracted effort at lighter but good-sized weights doing the latter to better advantage.
