I'm 5'4, fairly fit, and moderately active, and mine's at 320. I hit it easily pretty much every day unless I have an especially sedentary day where I do nothing at all. I've only missed it 4 days this month, most of those being related to having been asleep for 12+ hours of that day.
495 is the highest I've hit so far, though, so I guess my level of daily activity generally falls in a fairly narrow range. I'm going to have to up my game since I really want that damn Double Move award-- I was so annoyed when I discovered there was no award for lapping yourself on the Exercise circle the way there is for Move...! 🙄
