I recently returned to a desk job after a few months on extended holiday. During my vacation, I ate and drank pretty much what I wanted but didn't gain any weight because I walked everywhere (easily 3 hours a day). Things changed though, as soon as I got back to work where I sit in front of a computer all day. Without modifying my diet, I've managed to put on more than a few pounds, as my only exercise is typing.

It can be really difficult though to find the time to fit in exercise when you work 8 hours a day, especially if there are no gym facilities in or near your office. I think this is a shame because I find that daily exercise makes me feel more alert and awake throughout the work day.

So I was pretty excited to find this page that has a series of tips and links to sourches which teach you how to do yoga at your desk. Stretches can be done through 2, 15-minute breaks or over a half-hour at lunch. Yoga poses will help you stretch and relax, and work out the stiffness that can result after hours at a desk. The only catch? Many moves are done at your desk, so make sure to let your boss and co-workers know what you're up to so that you don't weird them out.
