basically you are right. That’s why I was looking for a device that covers most things, so I don’t have to add much.
Flat bench, incline bench, Olympic barbell + plates, dumbbells, bedroom bar, various cable handles, hyperextension
Except for the hyperextension, the device offers everything and does not require any additional space.
But yes, maybe a more space-saving version of individual devices makes more sense. For example, there are cable machines to screw onto the wall that require no space except for the user. I have also considered a cable crossover from one side of the room to the other that you can walk under, which also looks less bulky.
I also find something like this very interesting, which with a shallow depth of 70cm and a suitable width of 280 can be nicely placed against the wall opposite the double windows or the front side of the room. Unfortunately without a smith machine. It depends on what I want, of course.
