Frank Grillo Shares His Secret, How He Maintains 5% Body Fat At Age 52

Captain America’s incredibly fit actor offers up his advice for staying lean on ‘The Tonight Show With Conan O’Brien’.

Frank Grillo maintains an astounding only 5% body fat at the age of 52-years-old. That’s a body fat percentage that most teenagers in peak physical condition would never even be able to reach but Frank Grillo is crushing it at an age where 18-22% is considered ‘healthy’ and 22-28% is still below the ‘obese’ mark.

What’s the secret to his fitness success? The familiar, reliable one-two punch of exercise and diet—but not just any exercise and diet. The actor, who played “Crossbones” in Captain America: Civil War and Captain America: The Winter Soldier, admits that he’s been training like a professional fighter and maintaining a Paleo diet for years.

But Paleo works, and if you want to get trim then it’s certainly a viable option to achieving that goal. Personally, I love food too much to ever eat like a caveman so I’ll just embrace my climbing body fat percentage.
