Take the stairs instead of the elevator. Go for a walk after dinner. Play tag with your kids at the park. New research shows that even small amounts of exercise - about 150 minutes, or 2.5 hours, of moderate activity a week - can reduce the risk of heart disease by about 14%.
The benefits of even more exercise continue to add up. People who reported exercising for 750 minutes a week, or 12.5 hours - had a 25% reduced risk of heart disease. But that's many more hours of working out for only a small additional risk reduction, Sattelmair noted.
