Inactivity is the greatest curse that could come upon most invalids. Light employment in useful labor, while it does not tax mind or body, has a happy influence upon both. It strengthens the muscles, improves the circulation, and gives the invalid the satisfaction of knowing that he is not wholly useless in this busy world. He may be able to do but little at first, but he will soon find his strength increasing, and the amount of work done can be increased accordingly. RY 132.2
Exercise aids the dyspeptic by giving the digestive organs a healthy tone. To engage in severe study or violent physical exercise immediately after eating, hinders the work of digestion; but a short walk after a meal, with the head erect and the shoulders back, is a great benefit. RY 132.3
Notwithstanding all that is said and written concerning its importance, there are still many who neglect physical exercise. Some grow corpulent because the system is clogged; others become thin and feeble because their vital powers are exhausted in disposing of an excess of food. The liver is burdened in its effort to cleanse the blood of impurities, and illness is the result. RY 132.4
Those whose habits are sedentary should, when the weather will permit, exercise in the open air every day, summer or winter. Walking is preferable to riding or driving, for it brings more of the muscles into exercise. The lungs are forced into healthy action, since it is impossible to walk briskly without inflating them.

Such exercise would in many cases be better for the health than medicine.—The Ministry of Healing, 240. RY 133.2
