Any amount of exercise appeared to reduce all of these risks. For instance, those who got between 3.5 and 5.9 hours of moderate to vigorous exercise per week were 50% less likely than total couch potatoes to die for any reason. People who exercised 1 to 3.4 hours per week saw their risk fall by 44%. Even those who exercised for less than 1 hour per week were 35% less likely to die of any cause while they were being tracked.
