The INSIDER Summary:

• Anthony Bourdain showed off his toned body while on vacation in Italy with his girlfriend Asia Argento. 
• Bourdain revealed his secret to staying in shape is Brazilian jiu-jitsu.
• The celebrity chef and TV host trains everyday, no matter where he is in the world.

Last week, the traveling TV host was photographed with girlfriend Asia Argento in Italy, heading to the hotel pool in swim trunks. Although Bourdain has been photographed without a shirt before (even once alongside Iggy Pop), these most recent shots are a reminder of the 61-year-old’s current passion: jiu-jitsu.

In an interview with Nuvo magazine last year, Bourdain spoke at length about his fitness regimen. “I train every day, wherever I am in the world,” he told the magazine. “When I’m in New York, I train at the Renzo Gracie Academy, an hour private and then an hour and a half general population. That’s basically Fight Club.”

Since beginning his Brazilian jiu-jitsu practice in 2014, Bourdain won a competition and earned his blue belt (the second level for adult practice). However, when speaking with Men’s Journal last year, he called himself a “blue belt who doesn’t suspect he will ever make it to black belt in this lifetime.”

In addition to the physical benefits, Bourdain also enjoys the mental impact of jiu-jitsu, mainly the "incremental tiny satisfactions of being a little less awful at something every day,” he told Charlie Rose.

Of course to reach the 61-year-old’s physicality, diet is equally as important as exercise. Although he’s been known to duck out in the middle of the night for fast food macaroni and cheese, the former chef maintains a thorough understanding of what he puts in his body. He told Travel + Leisure that he doesn’t even eat on the airplane as he knows his body will not digest the food.
