What Is 'Couch Potatoes'?

— -- "Couch Potatoes" is a twice-weekly program on ABC News Now that looks at a range of physical activities and health trends, including sailing, baseball and weight training, yoga, tap dancing and massage therapies -- just about everything to motivate you to get off your couch and into a healthier lifestyle.

"Couch Potatoes" also delves into diets and nutrition. Personal trainer Jim Karas' energy and enthusiasm drive the program, and he is willing to try anything -- once, at least. Karas makes it fun to get moving.
