Power walking?

The partner of a friend of my wife (the one whose daughter finds werewolves cute and think I have the eyes of her cat) told me once that he saw me walking to the train station on my commute to work and that I was not merely walking, but more like power walking. Well, I don't know, I do walk fast, especially when I want to get done with something. Or simply when I don't want to miss the train. I used to arrive just on time to catch the train, just before it left the station. Now I have minutes to spare. It is less stressful. Maybe I leave earlier, maybe I walk faster. Power walking is supposed to be healthy, it may be useful to burn some calories, I mean more than merely walking. But I find the look kind of ridiculous, or certainly unaesthetic. So I don't want to look like I'm power walking.
