There are many walking desks out there for people looking to move while they work, but check out the TreadDesk. This one can be built into your floor allowing you to roll your chair over it, which makes this walking desk seem less like a gym and more like your office. The desk's height is adjustable, so you can sit at this workstation or raise the desk and stand, stretch, or turn on the treadmill and walk.

The tread itself costs $695, and you can lay it on top of your present floor, but if you want it to be part of the floor, they offer laminate-flooring options. It costs about $4 to $12 per square foot, depending on the style you choose. The desk comes in six sizes, but if you need a different size, it can be custom built. What's great about these is the little button underneath that allows you to raise the desk so you can stand. These range in price from $900 to $1500. The whole system isn't cheap, but I think it's definitely worth the moolah since most people can spend over seven hours sitting at their desk. Why sit when you can burn calories walking instead?
