It depends. Like Muddy said, 10,000 is the base but my sister gets over 20,000 a day because she works at a GM plant. My other sister barely gets 7,000 a day because she stands behind her desk but doesn't walk muchI put one of those dumb step counters on my phone about a hour after getting to work this morning.
We'll see how that goes. How many steps is a productive day?
