Truth: Not ready to conquer a marathon? No problem. You can get many of the benefits of long-distance running without ever passing the five-mile mark. 

Running fast and hard for just five to 10 minutes a day can provide some of the same health outcomes as running for hours can. In fact, people who run for less than an hour a week — as long as they get in those few minutes each day — see similar benefits in terms of heart health compared to those who run more than three hours per week.

Plus, years of recent research suggest that short bursts of intense exercise can provide some of the same health benefits as long, endurance-style workouts — and they also tend to be more fun.
