I used to worry about that when I lived in an apartment too. I just tried my best to do it when I knew they weren't home or not awake. Not exactly a solution, but I know that you CAN hear someone above you disco dancing all around the living room, so just try to pay attention to schedules. The worst thing that could happen is just that they ask you to stop the racket and then you could ask when is a good time for you to do your exercising instead?
HTH!
