“I was always addicted to strength,” admits 73-year-old power lifter Bill McFayden. Though he’s old enough to be a great-grandfather, this ripped Scotsman is as enthusiastic as a schoolboy when discussing his love of pushing punishingly heavy weights into the air while looking like someone you would never, ever want make a Highlander joke about.

Still, had Mel Gibson been as cut as McFayden, Braveheart would have ended differently.
