Have exactly same issue. I use a stopwatch on my watch, set it for 45 minutes, and every time it goes off, I force myself to do some short useful activity. This may be: - a short stretch, - a short light weight lifting session, - making a coffee, - cleaning up a small part of the house, - doing a small step of any other physical chore. Those can take 10 seconds or 5-10 minutes, depending on the activity. Usually there will be 1-2 longer breaks of this kind, and the rest are the shorter ones. I especially like how some house chores goes away thanks to this!
