My daughter in law has a standing desk at work, and a walking treadmill under it. It’s worked well for her and has not affected her work (she’s a marketing assistant).
On a different note, my son got me a pedometer because he didn’t think I was walking enough. I wore it a few weeks and logged 8-10,000 steps per day, lol. Between housework, farm work and gardening, I keep pretty busy!
I love that our kids think we don’t get our exercise in! Do they think these chores get done on their own?
