Although it isn't very difficult to actually work on a Treadmill
Desk, there are certain tools that will make the transition more efficient and enjoyable.
Desktop real estate is very precious. I use a mini-sized keyboard to save space. Check eBay or Google "small or mini-size keyboards".
Sometimes it can be challenging to use a mouse to highlight a website link while walking. I use a standard wireless mouse, but some Treadmill Desk walkers love their trackball mouse.
Positioning your computer monitor is very important for the Treadmill Desk to work well. Without a doubt, the best purchase I made was for two monitor arms (I have two monitors) that attach to the wall. My monitor arms extend up to 24" from the wall and pivot to every possible position.
Good Choice: Ergotron
I bought the Ergotron LX Wall Mount LCD Arm and I love them!
But to install this model (wall mount) you need to attach to a wood wall stud. I spent several hours learning how to do this.
Step 1: To locate where the wood studs are hiding behind the drywall, use a "rare earth" magnet to locate where the drywall screws are attached to the wood stud.
Step 2: Then once you know where the stud is, use a very small nail (8 d or 8 penny) and actually pound it into the wall to determine the exact location of the two edges of the wood stud.
The less cords and cables the better. Therefore, buy a cordless telephone and keep the base unit elsewhere in the room. Just keep the handset on your desk.
This device allows you to split the VGA video coming out of your computer to two monitors. The same image is seen on both monitors. Therefore, you can have one monitor at your Treadmill Desk and a second monitor on your "normal" desk. That way you can switch back and forth between your Treadmill and normal desk without having to move your monitor.
The difference between the following two choices is that the Aluratek provides a split signal all of the time, whereas the 2-1 HD15 only provides an output to the monitor you choose via the manual switch. The 2-1 HD15 works great and it's only $10!
Aluratek AVS02 2-Port VGA Video Splitter $34
My Choice: 2-1 HD15 VGA Manual Switch Box
Two Mice and/or Two Keyboards
It's been my experience that if you're using a USB mouse and/or USB keyboard (either wired or wireless) then you may have two of each plugged in at the same time with no ill effects. That is, you can have one set of mouse and keyboard for your normal desk and one set for your treadmill desk. This is a great configuration so you may easily go back and forth between the two desks.
