According to a new study published in the Journal of the American College of Cardiology, running 5 minutes per day can reduce an individual's risk of premature death by about 3 years. Researchers found that people who ran less than an hour per week also saw an increase in lifespan, not just a decrease in risk of premature death. The study took place over the course of 15 years, testing participants ranging in age from 18-100.
Separate research found that running more than 20 miles per week could take years off an individual's life, providing further evidence that less can be more with regard to exercise. According to that research, individuals who exhibit consistent but moderate workout patterns are likely to live the longest.
