Are there different benefits between moderate and vigorous activity?  In 1986 a study took 44,551 men, ages 40-75 years old and over the course of 22 years examined “the relationship between vigorous-intensity physical activity, compared with moderate-intensity activity.” Their study found that the men who performed moderate-intensity physical activities had fewer cases of chronic diseases, such as cancer, as well as cardiovascular diseases. That’s great news that if you amp up your workouts, you set yourself up for greater health in the long run.
