You may hear your doctor tell you to “get your heart rate up.” What that means is cardiovascular exercise. The reason they tell you this is that cardiovascular exercise, or cardio as it’s often called, benefits your heart! Cardio is any exercise that raises your heart rate for an extended period and works large muscle groups. Not only will your heart reap the benefits, but the rest of your body will as well. Research suggests having a cardio routine in place can help you live a longer, healthier life.
