Workout Area in Empty Room Beneath Family Room

So today as I had a lot of time on my hands, I checked out the room beneath the family room, it is just unused, bare concrete, with a lot of junk and dirt in it. Took a couple of hours to clean it up, but I did it, and now all that is left is some excess insulation, about 40 (useful) 2x4s, and a nice space that will be good for weightlifting. Only issue is the height. Some parts are only 82", which is not enough to overhead press a barbell. However, the insulation compresses in the ceiling, so I have about 92" of space if I aim right, so I should be okay.

I have a convenient window that opens and comes out right to the patio that I could use as an easy way to get weight plates and a barbell out to do outside pressing work on a nice day. Otherwise its careful pressing or seating presses, not a big deal.
