There is considerable of a swing at the hips, in fact a distinct roll--the hips swaying an inch or more to the stepping side with a corresponding long pace. The leg is swung back and forth from the hip, the knee joint aiding this motion by adapting the leg to the irregularities of the ground surface. As employed by professional long-distance walkers the hip action is somewhat exaggerated. The hip roll is regulated to some extent by the swing of the arms which should alternate with the leg action. This is a means of instilling a lot of energy into the gait. The tendency is to overdo--to swing too vigorously and by overswaying disturb the body balance with a resultant fatigue. As an aid to this, some professional walkers use a two foot light walking stick or riding crop held in the hands. The arms may be held any way desirable but it is advisable to carry them well up. Woods walking with a pack differs greatly from common road touring. In his primitive forest habitat the woodsman can outwalk the experienced pedestrian for he has the knack of negotiating a steady gait over uneven and slippery ground, edging through thickets and worming his way amid fallen timber, rocks, brush, etc., with less fret and exertion than one who is accustomed to smooth, unobstructed paths. The woodsman besides having the handicap of traveling over an uneven surface is more or less encumbered by a pack which even if made as light as possible gives the hiker a taste of real work. The long swinging gait of the bushman is less tiring than the straight ahead stiffer stride of one who walks on smooth ground as on city pavements. This woods walking is acquired with experience as a result of physical adaptation to repeated emergency footing exigencies. The poise of an Indian in the act of stepping would be found to be a perfect body balance on each foot. This allows great control over movements: the characteristic silent stealth of the redman displays the greatest economy of vital force. He conserves his strength and makes every step count, often going around many places which otherwise he could make with a hop, skip and jump--a desideratum in preventing fatigue in woods walking where the steps must be of unequal length and the footing so different. There is no doubt that walking is unexcelled as a short cut exercise to the attainment of physical fitness. One should never try to accomplish too much at one time, for overdoing disgusts one with the pastime. Start in easy, walk deliberately, adopt an easy, natural gait and maintain it. Short rests are permissible but if overdone they result in stiff muscles and chill.
