=The Loins.=--The muscles in the small of the back, running up and down on each side of the spine, come into play in many forms of manual labor, and should therefore possess strength and endurance. Working with the shovel, or fork, or bar, or saw, or any exercise requiring a stooping posture, brings them into action. Several of the exercises recommended for the abdominal muscles will prove of advantage here. Raising dumb-bells above the head, first with the left hand, then with the right, then with both, beginning with bells weighing a pound or two, and each month, with daily practice, adding a pound to the weight until it reaches about one-twentieth the weight of the person, will bring the desired results. Running or rapid walking, with the body erect, will prove helpful. Hopping straight ahead for from five to ten steps on one foot, then on the other, and thus alternating for from twenty to one hundred steps, or more, will soon beget strength, and give a firm, steady carriage. =The Back.=--The muscles of the back, above the waist line, participate in nearly all the movements recommended for the chest, shoulders, and upper arm, and do not require special exercises. =The Shoulders.=--To round out hollow shoulders and put muscle on the upper back, stand erect, with light dumb-bells, arms hanging at the sides. Without bending the elbow, keep the arms parallel, and carry the bells backward and forward as far as possible. Hold for a few moments, and slowly return to the sides. Repeat five to ten times. As strength increases, gradually add to the weight of the bells and the number of lifts, also endeavor to carry the arms a trifle higher. For developing the muscles of the shoulders, back, and wrist, few exercises are better than light Indian-clubs. For the outside of the shoulder, bring the arms to the horizontal, elbows rigid, and move the bells up and down through a space of twenty inches. Repeat five to ten times. Carry to the front and repeat. A few weeks of daily practice should show noticeable results, and a year of persistent drill will produce a shapely shoulder, and make it unnecessary for the tailor to pad the coat in order to make it fit. =The Neck.=--The muscles of the neck may best be developed by the use of a strong rubber strap, about two feet long. Attach one end to the door frame, about the height of the head when standing, and fasten the other end to a band which loosely encircles the head. The front, back, and sides of the neck may all be strengthened and filled out with firm, shapely muscles, by changing the position of the body for each change of exercise desired. Keep the head firm to resist the pull of the strap. Increase the length of the movement and the strength of the pull, as the muscles grow strong to bear it.
