I got plenty of exercise going around the whole thing all the time. My longarm is on wheels so I could put it against a wall and move to the other side when I wanted to change from front to back or the reverse. I never had to do that and would avoid it as it is just more work to deal with. Once you know how much room you'll need for a longarm you can add to the space to create your full sewing room.
