I think the way you are doing it is actually really natural and should benefit you well.
I recently got a standing desk. It will take some time to get used to.
I also moved to a new office that is further away from things on campus and also 3 flights up. So I do a lot of walking. Plus the ladies restroom is on another floor so I do a lot of stair climbing. I think even the longer walk to my parking space has made a little difference.
