Any of you have a treadmill desk or tried one? I sit all day and write so I like the concept…though I’m not the most coordinated person. Don’t know if I’d fall off the silly thing. But the idea of walking and clocking a good number of miles each day while working. Well, the healthy part of me stands up and cheers. They are expensive. I know you can make your own but I’m soo not mechanically inclined -grins. Thinking about selling the flat screen to offset the cost. Thoughts?
