One Foot in Front of the Other

What may be the first scientific conference devoted to the health benefits of walking is taking place on the UI campus. The three-day "Walking for Health" conference builds on years of research showing that moderate exercise like walking can be as beneficial as more strenuous exercise. AM 580's Jim Meadows took a walk with one of the organizers of the conference. Kinesiology professor Weimo Zhu (left) says there are still plenty of things that walking researchers want to know.
