Answer: Walking, running, swimming, biking, weight training and yoga are all excellent exercises for heart health. Regular exercise will make your heart stronger as well as burn calories, lower blood pressure, and improve your cholesterol. The US Department of Health and Human Services recommends at least 150 minutes per week of moderate activity or 75 minutes a week of vigorous activity. Even if you are healthy, but have not exercised in a long time, you may need to talk to your doctor to make sure that you are in good physical condition to exercise.
