I try to find micro-moments throughout the day at work, either sitting at my desk, alone in an elevator, in the bathroom, etc. Nothing serious, but a bit to regain focus & center during turbulent days.
I used to do yoga in my office (have a private office with no windows) for a bit. I loved it but occasionally when someone knocked on the door things were awkward. If you can pull it off in a way where you won’t be interrupted I’d say go for it.
