Is exercise the solution? Suppose you do 100 sit-ups every morning. Can you safely sit back and rest on your laurels the rest of the day? Research says no. Despite the good it does for you in many ways, exercise is not a vaccine against the ills of sitting. Once you burn a bunch of calories, they're gone, of course. But it doesn't take long for some of the other beneficial effects of exercise to wear off and the detrimental effects of sitting to set in. For instance, lipase production can go down by 90% within hours, a 2008 study in the journal Diabetes found.
Is there any hope? There are ways of outwitting our penchant for sitting. Levine has a treadmill at his desk that he strolls on all day long. He made his own, but many models are commercially available. Indeed, whole lines of furniture have been developed to facilitate what David Kahl calls "active sitting."
It can take a while for people to adjust to this new way of sitting, says Kahl, who owns the Ergo Depot in Portland, Ore. "But in the end I haven't had anybody say, 'I can't do it.'"
There are simpler steps to take too — e.g., merely increasing the number of steps you take during the day. But can such small things really make a difference? A study published last year in Diabetes Care showed you can improve your glucose metabolism with a two-minute walk every 20 minutes.
Considerable anecdotal evidence points in the same direction. True, many — perhaps including you yourself — have done some of their best work while sitting at their desks. "That's where I shine," the late writer Robert Benchley once said. But many others have achieved remarkable success while standing up on the job, including Winston Churchill, Charles Dickens, Benjamin Franklin, Ernest Hemingway and Mark Twain.
