Get a treadmill desk with a seat that will sit on top of it - barstool type seat - so you can switch back and forth. Super helpful to get 10k steps per day.
10k steps a day might help OP initially, but I found after getting a full size treadmill 10k steps for the day was usually done after one episode of any TV show if I left my house for any reason that day, even if it's just a walk around a couple blocks for air.
Bathroom breaks, walking around to stretch, doing a load of laundry will easily get you 4k to 6k steps. 10k ends up being a very low goal once you make any attempt.
