Heart disease is America’s Number 1 killer. To improve overall heart health, the American Heart Association suggests:
At least 30 minutes of moderate-intensity aerobic activity at least five days per week for a total of 150 minutes
At least 25 minutes of vigorous aerobic activity at least 3 days per week for a total of 75 minutes; or a combination of moderate- and vigorous-intensity aerobic activity
Moderate- to high-intensity muscle-strengthening activity at least 2 days per week for additional health benefits.
Aerobic exercises include walking, jogging, swimming, biking, climbing stairs and many sports. Strength and stretching exercises are best for overall stamina and flexibility.
The simplest positive change you can make to effectively improve your heart health is to start walking. It's enjoyable, free and it can be social. If you don't think you'll make it for 30 minutes, set a reachable initial goal and increase your goals gradually. Some exercise is always better than none!
