• Disney CEO Bob Iger says diet and exercise are critical to doing his job well.
• Iger said he wakes up early and works out because it gets his mind and body ready for the day ahead.
• He said that exercising gives him energy and helps him to motivate others.

Disney may be known for its magic, but there's nothing mystical about one of CEO Bob Iger's tips for excelling as a leader: diet and exercise.

Iger, 73, wakes up early and works out for about an hour "for sanity and vanity purposes," he told a recent episode of the "In Good Company" podcast.

Exercising clears his head and prepares him for the day ahead, Iger said. "Staying in shape, having stamina is critical for me, and that's eating well and exercising and just taking care of my body and my mind. I could not do this job if I were not in some form of physical and mental health."

Disney is one of the biggest US companies with $90 billion-plus in annual revenues and a market value north of $200 billion.

Iger first served as CEO between 2005 and 2020, spearheading the acquisitions of Pixar, Marvel, Lucasfilm, and 21st Century Fox's entertainment assets. He returned to lead the company in late 2022.

He's widely credited with turning Disney into a hitmaking machine that monetizes successes like "Frozen" across movies, TV shows, theme parks, resorts, cruises, toys, clothes, and video games.

Iger, who is known to rise at 4.15 a.m., said that getting up early vitalizes him and "a great leader has to be an energetic leader."

The Disney chief emphasized he's not a machine and doesn't always come bouncing into the office.

"Look, I'm a human being, so if I'm really tired from global travel and long hours and who knows what, I'm not afraid to show that to my people, because I think that's a way of being relatable," he said. "They feel that too — it's human nature. Sometimes you feel overworked and tired."

But Iger said that "for the most part, you've got to bring your energy to your job every moment of the day, meaning every waking hour, because it's motivating," he said. "Energy is motivating."

Iger is far from the only CEO to prioritize health and fitness. Apple's Tim Cook also wakes before dawn to work out for an hour most days, while Meta's Mark Zuckerberg has taken up martial arts in recent years.

On the other hand, Warren Buffett, the 94-year-old CEO of Berkshire Hathaway, famously enjoys Coca-Cola, McDonald's, and other junk food.
