Running or jogging at a 6 mph pace is a great choice for adding cardiovascular exercise to your workout routine. Running gets your heart rate up, burns calories and can help ward off problems such as heart disease and high cholesterol. It can also increase your lung function, give your immune system a boost and lower your risk of developing clots in your lungs. Even if you're used to walking, you can begin a running program by alternating running and walking until you are comfortable with running for a longer period of time. Or, try a running challenge that will help you get up and running in no time. How many calories you burn doing running or jogging depends on your speed, weight and gender.
