Exercise helps keep your body healthy and your tissues and organs working properly. By keeping your body in good working order, exercise also helps ward off many diseases, such as
type 2 diabetes
, and many others.
In 2008, the United States Department of Health and Human Services released physical activity guidelines for Americans. They recommend that adults should do at least 150 minutes of moderate–intensity or 75 minutes a week of vigorous–intensity aerobic physical activity per week. For additional health benefits, they recommend that adults increase this amount to 300 minutes of moderate–intensity or 150 minutes a week of vigorous–intensity per week.
Your exercise program should include:
In aerobic exercise, you continually move large muscles in the legs and buttocks. This action causes you to breathe more deeply and your heart to work harder to pump blood, thereby strengthening your heart and lungs.
Examples include: WalkingJoggingRunningAerobic danceBicyclingSwimmingHikingPlaying sports that involve running, such as basketball and soccer
