In case you're not aware, the SkyLink train is the fastest link between all terminals at DFW (it's about a two-minute ride between terminals A and B). It is clearly marked throughout each terminal, and it has two stops in each terminal. Just keep an eye out for the SkyLink signs, which will direct you toward the escalators and elevators leading up to the stations.
Yes, walking is good if you need the exercise. But, in addition to a new train arriving every two minutes, it takes only nine minutes to go from any SkyLink station to the farthest SkyLink station from it.
