Of all the advantages of exercising, the physical benefits are the most well-known. Regular physical activity can strengthen the heart and lungs, and increase muscle strength, and lower blood pressure. It can also promote the growth of bone density, reducing people’s chances of developing osteoporosis. By helping us to maintain and improve overall physical fitness, exercise lowers our chances of developing chronic diseases. Conversely, a lack of physical activity can increase our risk of health problems. Those who never or rarely exercise, for example, are at greater risk for high blood pressure, which could eventually lead to a heart attack or stroke.
