See much you exercise
You want to get up out of the chair more often, but sometimes you need a push. The FitBit Force ($130; on back order as of early November) can make a game out of staying active and doubles as a watch (if you don't mind pressing a button for the time).
Each step adds up. Tells you how many steps you take and even the miles you travel.
Take the stairs. The Force also detects changes in your altitude, which means it can count the number of times you hit the stairs. (It knows if you take the elevator instead.)
Link up wirelessly. Sends your data when you are near your computer or some smartphones, so you can track your progress.
Best new no-sweat advice
Take a break from that chair. Even if short bursts of heart-racing sprints and calisthenics aren't for you, just spend less time sitting.
Recent studies of a large group of over-45 Australians have found that people who sit for prolonged periods each day are at greater risk for chronic disease and earlier death. Find 10 minutes six times a day to stretch your legs and pump your heart, suggests David Nieman, professor of health sciences at Appalachian State University.
