Transcript for Exercise Study Finds Less Is More
surprising news about exercise. Oh, yeah, we do. Kind of goes against everything else that we learned in -- maybe I could eat like that, doc, after this news. Running on your treadmill may be as beneficial as more time on a treadmill so we got Dr. Richard Besser to tell us, is this true? This is very surprising. They followed 55,000 dulls for 15 years and they found that those who ran were 45% less likely during that period to die from heart disease, 30% less likely to die from all causes but the surprising thing was, it didn't matter whether you ran five minutes a day or 30 minutes every day. What? At a hard speed? It didn't matter. If you were a runner, you got the benefit. For me now I can cut back or actually I need to add five minutes a day to running for myself? We were talking -- we don't like to run but the thing here is at the start of the segment people who run in general, they were healthier, they were less smokers, they were less obese so they're healthier people but the exciting thing here is it's showing that any kind of exercise has some benefit. That you don't have to exercise like you in order to get some health out of this. But just very quickly, to runners out there who are watching this morning, they can cut back a little bit and still have the same benefit. I wouldn't say cut back. The couch potatoes saying I don't have 30 minutes a day get up and do something. Anything. So I haven't wasted all that time pounding the pavement.
