In your garage can you setup for press and squat at the same time?
I ask because I got a second bar to shorten my workout time. I setup press or bench, and also squats. Then superset those resting half as much as I otherwise would.
So maybe get a second bar and start building a set of metal, or thinner bumper plates. That way you can keep what you already have, in case you ever do cleans or snatches.
Just a thought.
