I have a couple that lives above my apartment and the guy regularly workouts in his apartment. His workouts happen 4-5 times a week sometimes twice a day. Weekdays he'll do a workout 630am and play electronic music at the same time. Sometimes he'll workout again 530pm.

I know the sound I'm hearing are the result of dumbells/barbells bouncing on the floor because he's doing 6 reps and dropping the weights on the last one. He will do a few sets. Workouts last anywhere from 30 minutes to an hour.

I've tried getting the attention of building management but they don't seem to want to get involved. When I initially complained, they reached out via email to my neighbor and he responded that he was away on vacation.

As retaliation, for the past week I started blasting music all day (we both work from home) right when he starts he workout. I can hear him scrambling trying to find a way to soundproof the floors. Him and his girlfriend can't get into bed until I turn off the music. So far I haven't had any of the other neighbors complain about the music (I hardly see them). I stopped for a couple days to see if he would stop working out, but he was back at it again and I immediately turned on the music again.

For the record, I've never seen/met him in person.
