It's really all in the title...
I'm looking for ways to incorporate a bit more exercise into a desk-worker's life, and I recently stumbled over the idea of building a treadmill desk.
A Treadmill Desk is a working desk built around a treadmill. A person using the treadmill desk walks slowly on the treadmill while continuing to perform office tasks at the desk. [...]
The aim of a treadmill desk is to integrate movement and gentle exercise into the working day of an otherwise sedentary office worker. Rather than sitting all day in a chair, a treadmill desk allows desk-based workers to stand and take a slow walk while working.
A treadmill desk is not typically used for a cardio workout, as most users find walking at a speed of 1.0 - 2.0 mph the ideal range. At slower walking speeds, most able-bodied people can undertake desk-based tasks such as typing or talking on the telephone. However, even at these slower speeds, a person may burn 100 - 150 calories per hour, which may result in increased fitness and weight loss.
Being able to walk for a substancial portion of one's workday sounds promising, but I'm wondering if there are any downsides with the use of treadmill desks in general, or maybe things to look out for.
