I thought a very low and compact version of a bench to do floor presses would exist but I have never found one, maybe I'm not using the right keywords. Just a short, narrow sturdy piece of equipment to lay on to get my back off the floor just enough to get some range of motion.
I was in the middle of replying how that would be perfect "if only it were more narrow like a balance beam." Looked up floor balance beams and they exist. Thanks for the assist.
