Discovery has internal centrifuges, there are no rotating seals because the space beween the outside of the centrifuge and the inside of the non-rotating hull can be pressurizzed. For two counter-rotating internal centrifuges you either have two of those cylindrical interior spaces or put them next to each other. You'd need to go to the center, non rotating part of the ship to enter the other centrifuge.

It isn't like the centrifuges need to spin very fast if you're only going for moon gravity at Discovery's size. Plus if you run on the track you can exceed earth's gravity during your excercise.

As for depressurization and airlock location. You put an airlock at the entry-exit to the centrifuge area and on the rotating centrifuges themselves. You'd also want to plan for how you're getting an astronaut or repair drone to the interior of the pressurized hull (outside the centrifuge.)

I drew a picture, talking about the yellow volume. It could be wasted space or you could partially fill it with supplies.
