So you would like to get some work done while walking on your treadmill? The Walk with Me treadmill attachment can help. It has a 32″ x 11″ x 1/2″ top to hold any laptop, tablet, or phone. You can attach/detach boards in a flash thanks to industrial grade velcro.
You don’t have to remove the whole thing to start running. Just lift the top board, and you are set. A Phillips screwdriver is all you need to install this.
