Look, I've been saying that - *sitting is death* - for a while now....but since nobody listens to me, perhaps they'll listen to Tim Ferriss?
He's got a blog post up (laced with very high-priced affiliate links!) that pretty much corroborates my own independent assertion.
The opening line is a haymaker:
If you’re a white-collar worker, hacking your body isn’t limited to the gym. In fact, what you do outside of the gym might be more important that what you do inside the gym.
Recent research suggests that those who sit from 9-5 (more than 6 hours daily) and exercise regularly are more likely to have heart disease than those who sit less than 3 hours per day and don’t "exercise" at all.
Did you catch that???
Sitting all day MORE THAN OFFSETS exercise. Yeah, it's that bad.
And it explains why those European women can eat so much food and still stay thin...
THEY DON'T WORK - at least not at desks all day.
It's just too easy to sit, to drive, or ride the subway/train. None of our daily needs demand any exercise to be fulfilled.
You sort of have to manufacture situations of physical hardship. For example, nowadays I always walk and carry my own bag when golfing - as intentional exercise.
And yesterday when we got off the train at Penn Station I made my kids walk 2.9 miles through Manhattan to get to their art fair - not to save a subway/cab fare, but rather because they don't get near enough exercise naturally in my estimation.
