For some, the news seems to be the best walking companion. Another option that works for some people is renting a movie and watching it in workout-sized segments. Just as a good novel can draw you like a magnet to a cozy corner, a good movie may get you to the treadmill to snatch a few minutes of the plot. Go faster, stronger, longer. There's nothing like a treadmill to force you into an interval training session, whether your goal is to get faster, burn more fat or increase your endurance.
Most treadmills have at least a timer.
Some have elaborate settings to create your own programs. Try creating a program as you go along, listening to your body as you push and then kick back. Listen to your favorite tunes. Sometimes, when you're listening to the right music, your walk can feel like a powerful dance. Listening on headphones makes the music seem to filter right into your bones.
