With all the recent hype about "lift heavy," I am unable to do that with my legs. I have a machine for upper body along with elastics. Maybe I am too worried about "Over Doing it at The Gym," as this thread is titled. Unfounded concern?
Your unfounded concern isn't unfounded at all, it is perfectly legitimate so don't worry about it. Just continue doing what works for you. You don't need to train like a powerlifter in order to maintain bone density. Yes it's true that bones respond to mechanical loading and stress just like muscles respond to mechanical loading but that doesn't mean you have to train like a powerlifter and lift extremely weights in order to maintain bone density and maintain muscle function. As long as your exercise routine and activities which you do create some level of fatigue and stress on your body then that's all that is necessary.
