By the year 2030, one in five people will be 65 or older and 12 percent of the elderly will be 85 or older. Some people may not exercise because they don't like vigorous activity, don't have the time or are worried that it will aggravate a medical condition. However, researchers have found that moderate physical activity of at least 30 minutes a day will provide significant health benefits. Medical research shows that physical activity is safe and beneficial for people with arthritis, high blood pressure, osteoporosis and other chronic conditions. In fact, the lack of activity can make the condition worse or, at least, make it difficult to live with.
Physical activity can strengthen bones, relieve joint stiffness and reduce pain.
Inactive people may encounter some muscle soreness at first, but it will disappear.
