Given their first try? I'd say 75~80 lbs. Given a LITTLE practice and a few helpful pointers (or letting them use a Nautilus)? About 100~125 lbs. Free weights take a bit of technique... and some getting used to.
I know technique played a huge difference in my "max" weight when I was in high school bulking up to play offensive line. It had nothing to do with "strength"... but when I had some better instruction, my "max" went up in virtually every lift by varying amounts (some as little as 10%, some as much as 30%).
