I have no clue what it was originally, but I'd guess that R might be "rows" and O could be "overhead press".
U has me completely stumped, though ... "upside-down" or "underhand" something, maybe?
And most of these work the shoulders, back and/or chest as well as the upper arms -- which is a good thing, but it means it's not just an "upper arm workout."
