The rock climbing is only bouldering for exercise on a climbing wall. The falling works about the same, though, except that there is padding.
I wouldn't say I'm so strict or lenient at hiking. How about lackadaisical? And don't forget the biking, the caving, the sailing, the rafting, and whatever activity comes along. One thing I have noted is I prefer duration over intensity. Biking for a few hours is exercise, and I may or may not do that. Biking for a thousand miles....well, that was fun. I'd do something like that again, but I'm kind of booked with some hikes for the next few years.
