Cliff Eggink is a 70-year-old former CEO known around the world as the Iron Geezer.

By his own admission, he was once a couch potato. But when he was 60 years old, he says something motivated him to change.

He tells Growing Bolder he didn’t just decide to get in shape, he decided to tackle an Ironman Triathlon. And he says he’s been joined in his athletic adventures by his wife, Tatjana, the Iron Gazelle.

He’s still redefining aging and has developed a Web site that shares exercise and nutrition tips. Click here to check it out.
