One of the good things about floor presses is that you have such a stable base for your scapulae; there's no chance of any imbalance, which has got to be good for shoulder stability.
I've been thinking about getting rid of my rack and getting some squat stands instead as they take up much less space and can be moved out of the way easily. It's all because my 6' York bar has bent and I can't find a replacement that's going to be any tougher. If I get a better 7' bar, I don't have enough space to use it safely across the width of the room as the room is only about 7' 6" wide. It's too likely that I'll bash the walls and the bar up. If I turn 90º then 7' 6" doesn't give me enough room to bail out safely should I need to dive out from under a bar.
The other option is that I convert my basement into a gym as that would give me a lot more space; but that will require a lot of work lowering the floor as there isn't enough ceiling height to lift a bar overhead, which sort of defeats the object of weightlifting. I was planning on a funky cinema room but maybe a gym would be better use of the space? Heck, maybe I just need to combine the two? Now there's a thought.
