Walk! Get up off the couch and go for a walk. Call a friend and go for a walk together. Walk in the woods, on the beach, around the store. Walk. It's simple. No equipment needed, no special training necessary. Take the dog, too, and you'll both feel healthier.

Bicycling counts too. Paddle a canoe or a kayak, toss a ball, run, skip, play basketball, baseball, golf -- it all counts toward your weekly miles.

Each booklet contains an activity conversion chart to help you determine how much exercise your chosen activity creates. The skies the limit.
