So what are the options for those of us who work at a desk for hours and hours?
Consumer Reports tested what could be the desk of the future - a treadmill desk. Some people have already made the switch.
Like many of us, Chris Brown felt sitting at a desk all day drained his energy.
So he made a change. For the past six weeks, Chris has been working - and walking - at his new treadmill desk.
It's not really for exercise, but to keep your metabolism above a resting rate.
The recommended speed while working is less than two miles per hour.
"I can do pretty much anything at the treadmill desk that I can do sitting down behind a desk."
Consumer Reports tested two treadmill desks, using a panel of 12 staffers.
"We had them read and type on the computer, we had them talk on the phone, and we had them surf the internet."
The workfit 1030 by Exerpeutic is less expensive at 750 dollars, but for some it wasn't comfortable.
"It's not an ideal height for a short person. Because as you can see my shoulders are hunched up, and if you type for any length of time, it's just, it's not doable."
And several panelists complained their feet kept hitting the motor casing.
"Ergonomically it was just easier to walk and work on the lifespan."
This lifespan TR1200 DT5 costs twice as much - 15-hundred dollars - but most panelists preferred it.
"The overall stability of this machine is very sound."
As for Chris Brown, he says switching to a treadmill desk is worth it.
"I just feel better about myself both physically and psychologically."
