Don’t sit all day at your desk and come home to plop in front of the TV. It is not going to help you burn any calories if you lead an almost comatose life. Every hour get up from your desk and walk up the stairs to a water cooler on another floor. Try to take the stairs whenever possible. Get off the elevator a couple of floors away from your destination floor and take the stairs. Instead of sitting down at watching TV set up an exercise machine like treadmill or bicycle. Walk or cycle away to your favorite movie. Instead of sitting down pick up a duster and clean the cupboards and shelves in the room while watching TV. Fold laundry or cut vegetables standing up and watching your favorite TV program.
