12k steps is about 2 hours. It helps a lot to have a walking pad (basically a mini-treadmill), and possibly standing desk.
I do 45 minutes of Anki per day on the walking pad, and then if walking around the city hasn't gotten the other 1.25 hours, I can fill the rest with watching TV on the walking pad.
