It’s not glamorous by any means, but I fashioned a comfortable treadmill desk and moved my Mac laptop down to use on it in our basement. I can now do research and keep in touch online while walking on the treadmill. And… I can still remote into the Mac from upstairs, so I don’t have to drag the computer up and down the stairs, which I know that I am less likely to do.
No, it’s not at a fast pace, but it sure beats sitting at my desk on the couch. One step for health!
