Walking at a treadmill desk, on the other hand, could wipe out more than seven hundred calories a day. Just moving at a snail’s pace at about one mile per hour, people burn an extra two calories a minute over sitting.3194 That means you could erase more than one hundred extra calories an hour while you work or two hundred extra calories at 3 mph.3195 (My treadmill desk is currently set at 1.8 mph.)
