Exercising to Protect the Heart
For the physically fit, vigorous exercise seems to offer more protection against heart disease than low-intensity exercise. But for people who do not exercise regularly and are out of shape, engaging in moderate exercise also can provide protection, according to the American Heart Association (AHA). The more vigorously you think that you exercise, regardless of whether that activity level meets exercise recommendations, the lower your risk for heart disease, an AHA study says. Health experts recommend 30 minutes of moderate to vigorous physical activity five to seven days a week. Be sure to check with your doctor before beginning any new exercise program.
