When I did my bushings a couple years ago it was a real battle. I think it depends on how much exposure your car has had to the elements/salt. But there was no way mine were going going to come out with a hammer. It took all 20 tons of a 20 ton press to get them out.
There is another method where you cut/burn all the rubber out and then slice the metal sleeve with a hacksaw and then you can just peel it out.
