There seems to be a bit of interest in this whole treadmill desk thing, so I thought I'd write a little more about it.
For the treadmill, I used a Phoenix 98516 Easy Up Manual Treadmill. I chose a manual treadmill for a couple of reasons. First, because manuals are cheaper. But second, and maybe more important, I read complaints that running a treadmill all day at low speeds will cause the motor to burn out quickly.
As you can see in the picture, I built a little prototype keyboard and mouse platform, which sits on top of the hand rails. I also have my laptop sitting on a box, about 18 inches above my regular desk.
Yes, I am able to type with both hands. I lean a bit on the cardboard platform for balance. Also, I have a bungie cord attached around my waist, as the speed of the manual belt is not exactly even and it's hard to keep a steady pace otherwise.
Notice I'm smiling as I work. That's because I love my job. Plus I am happy that I found an angle for the picture where my office looks halfway decent.
I walked three miles on Tuesday, and 4 miles on Wednesday. Today was spent in Dallas walking up and down real stairs with boxes in my hand, so I didn't have much left to give when I finally got back home for a few hours of work.
Tomorrow, however, I expect great things.
