The really strong guy at the gym has probably figured out the importance of rest. If you just watched him dead lift a ton of weight, odds are very good that he didn't dead lift the day before, even if he was at the gym working on something else. He also probably takes an entire week of active rest after every 6-8 weeks of heavy lifting. He's working his ass off, but he's also being smart about it.

Agreed. And I'm not literally running a marathon every day. A more accurate analogy might have been a triathlon or decathlon. I just wanted to paint the picture of somebody who's achieved success in something, but if you looked at them at the point end of having just done something exhausting... big surprise, they'd look exhausted.
