I count walking. The question didn’t specify VO2max or heartrate, etc. Deep, full-torso no-pause breathing is exercise, too, and might be a good fit for anyone bored by exercise that isn’t for travel (I feel same as you; if I’m not going somewhere I tend not to exercise unless to stretch like other mammals do), in part because it gives the body more oxygen, which I find helps me decide what to do next.
