It's clear that anyone sitting at a desk for full-time work will need to get up and get active in their off-hours to make up for all that sedentary time. It's also clear that many humans cope well with workdays entirely on their feet: laborers, restaurant workers, store clerks. But many of these jobs and roles feature a lot of good exercise: at least there's walking around, lifting, moving objects. So it is natural to assume that these sorts of workers get plenty of exercise on the job, and they can relax during their time off, without needing a lot of gym memberships or home equipment. Now we come to standing desks: so you're on your feet for the workday and you may have a better ergonomic stance. You won't get hemorrhoids or DVT or numbness, or whatever nasty stuff comes from sitting a lot. But neither are you really moving around! You're just standing there supporting your own bodyweight. If you're overweight, this may prove to be a chore in itself. So when a standing-desk professional finishes work, logic indicates that they'll need to also hit the gym, or swimming pool, or do some sort of real exercise, because they were essentially stationary. Yet, they've been on their feet all day! Aren't they fatigued?
