Noisy neighbor bangs on my wall…what a twist!

Well, well, well… I lurk for a while and now here I am I need of this glorious community and its input. I have lived in my condo (own it) for 9 years. I always have strived to be a conscientious neighbor as I have a strong sense of justice and not being a jerk. This guy moved in 1-2 years ago sharing my bedroom & bathroom wall. When I tell you this man has impacted my life that’s not the half of it. He “works out” at all hours of the night banging and making noise. He began doing this a few months ago. The neighbors below him are super old and have mentioned to me about how loud he is above them. I have accepted most of this noise because we share a wall and I expect to hear my neighbors, I always have here; and secondly I guess he’s just living his life and I don’t control others. But it has been waking me up in the middle of the night and then again at 5ish am when he slams his front door. I am not aware of a job he has as he is always around so he may work from home but I see him almost daily walking out a massive whatever pack of crappy beer to the recycling bin.

Cut to tonight, I am organizing my bookshelf and moving around paperwork and worksheets at 10:28pm. I was not moving or touching books or hitting any books against the shelf whatsoever, just papers and files that I stack horizontally. I’ve got one earpod in listening to music inside my ear and it’s pin drop quiet in my place sans my two air filters/purifiers/white noise machines so I can try to sleep through his nightly work outs (I still am woken up even with 2 of these in my room). Well boom boom boom he bangs aggressively on the joined wall. I honestly couldn’t believe it.

What would you do? I need to be able to organize my stuff when I have the time and energy to do so and wasn’t even being loud. How would you handle this? Do I bang in the wall when he wakes me up at 2am? What if he is an unwell human being is my worry. We have an HOA. I don’t want this guy to think he can just do this whenever I’m living my life.
