Exactly, the type of thinking behind that chart casts doubt and caused me to stop reading. Just getting to standing desks is a big leap for most cultures. And I say this as someone who had their treadputer setup featured on lifehacker 7 years ago.
I'd rather exercise for an hour and burn that amount.
Still, I think we can all agree that burning more calories is good: but I'd rather my company emphasis physical fitness in more 'real' ways than simply giving you a walking desk.
