Absolutely right, although I cannot lift the amounts you list. For me, weight lifting has nothing to do with "power lifting"..

I have a weight-machine and a few barbells in my house, and use them 2-3 times a week, sometimes more, sometimes less. I am older, I have no six-pack, I am not particularly muscular. It's not about that. It's about keeping what you have, and keeping what you have reasonably fit.

Muscles support your joints. Weight training also strengthens the ligaments and tendons that hold everything together. If you do it as "circuit training" (only a few seconds between different exercises), it also serves as cardiovascular exercise. All of this is important for everyone, especially as you get older...
