Recently, there was an article in New Scientist about this[1]. Basically, if you sit for more than 6 hours a day, one hour of exercise a day doesn't undo the damage.
The solution is to get up and move around often, i.e. every ~20 minutes or so.
Exercise is still good even if you stand/move around often. And standing all day also has its problems, like others have mentioned.
