To elaborate on strength being relative,
As long as you're gaining strength, that's what is important.
My 85 pound overhead press won't win me any StrongMan competitions, but I'll tell you that I couldn't imagine doing that with the same sandbag just a very short time ago.
And next year I'll look back and say "wow, that 85 was heavy to me but now it is a warm-up weight"
And that's how it goes.
As long as you're getting stronger, you're doing it right, it doesn't really matter what the poundages are.
It's about YOU, about each person gaining strength and health.
