TUCSON (KGUN9-TV)-- Running can be as easy as putting one foot in front of the other. We know it's good for us, but new research shows you don't need to be a marathoner to make it work for you. Researchers from across the country found that runners cut their risk of dying from heart disease nearly in half, and were 30 percent less likely to die from all causes. Even more surprising-- it didn't matter if you ran 5 minutes a day or 30 minutes a day. One small step or light jog at a time can bring significant changes to your mind, body, and soul. Experts say you should talk to your doctor before starting a new fitness regimen. And even once you get the green light, listen to your body. Back off if you're in pain or injured.
