Health benefits of exercise in short burst or longer bouts similar, new study finds

It turns out you don’t need to spend an hour sweating it out at a gym.  A new study proves it doesn't matter whether you exercise in long blocks or short bursts throughout the day, both will actually help you to live longer. Researchers at Duke University in North Carolina tracked almost 5,000 middle-aged adults for four years. They debunked the idea that your workouts need to be lengthy in order to ward off illnesses like heart disease and diabetes.
