Our bodies become so accustomed to sitting all day long, it becomes an ingrained habit. But you can start to break your inactive habit by swapping out a little of your sit-down time with some get-up-and-move time. Turn half of your lunch hour into a 30-minute walk or workout. If you take the elevator, opt for the stairs, instead. Swap out 30 minutes of TV time with a brisk walk or bike ride. If you drive to the corner market, walk or bike, instead. Once you get moving, you may find that being more active becomes an ingrained habit, instead of sitting.
