Right. Robert Heinlein wrote a story (perhaps it is Waldo --1942) in which one character wears a lead coat to protect against the risks of power distributed by radio. What I recall is that this character is still strong and energetic while others are weaker, though carrying around a significant weight would be a form of strength-training, I'd think.
