Physical activity is any form of movement that works our muscles and uses more energy than we use when resting. Walking, running, dancing, swimming, yoga and gardening are examples of physical activity. Being physically active, along with following a healthy diet and not smoking, is one of the most important things one can do to keep heart and lungs healthy. Physical activity strengthens our heart and reduces coronary heart disease risk factors. It can also lower blood pressure; improve and manage levels of cholesterol and other fats in the blood; improve our body’s ability to manage blood sugar and insulin levels, which lowers our risk for type 2 diabetes; help us maintain a healthy weight; and reduce levels of C-reactive protein (CRP) in our body, a sign of inflammation. High levels of CRP may raise the risk for heart disease.
