What Does MFP Consider a workout

hartk001

I'm redoing some of MFP settings, one of the questions it asks is how many workouts a week do you do. I don't know what that means

I can appreciate time spent in the gym, swimming, football and the like. I'm a pretty fast walker, take the dog for a good longish relaxed walk. Would that kind of activity count as a workout?

Thanks for your advice
