Airbnb CEO and co-founder Brian Chesky has made a surprising revelation about his personal health routine. He now uses artificial intelligence chatbots to analyze his bloodwork and determine which nutritional supplements he needs.
AI Steps Into Personal Nutrition
During a recent livestream on the "TBPN" platform, Chesky explained his unconventional approach. He uploads PDF files of his bloodwork results directly to an AI chatbot. The AI then reviews the data and provides him with specific recommendations.
The analysis recently identified a Vitamin D deficiency. Based on the AI's findings, Chesky immediately began taking supplements to address the shortfall. While he employs a former Mr. Universe as his personal trainer for physical workouts, he reserves AI specifically for guidance on nutrition and supplementation.
A Shift in Silicon Valley Culture
The 44-year-old entrepreneur's comments emerged during a broader conversation about the tech community's growing embrace of fitness. Chesky admitted this shift genuinely surprised him. It contrasts sharply with the culture he encountered when he first arrived in Silicon Valley in the late 2000s.
"When I came to Silicon Valley, I felt slightly self-conscious about wearing long-sleeve shirts," Chesky told the hosts. "I thought if I wore a short-sleeve shirt, people would assume I was a meathead and therefore not very intelligent. People simply did not lift weights back in 2007 and 2008."
Chesky's Fitness Background and Routine
The discussion on fitness began after co-host John Coogan mentioned viewers were eager to hear about Chesky's arm workout. Chesky, dressed in a fitted black short-sleeve shirt, responded with detail.
"Genetically, I have better arms than shoulders or chest," he noted. He does not dedicate a separate day to arm training. Instead, he incorporates arm exercises into his shoulder workouts.
His typical routine involves two bicep and two tricep exercises. He prefers combining a compound free weight movement with a machine exercise. For biceps, this might mean dumbbell curls followed by a Hammer Strength cable exercise using a rope or V bar. His tricep workout often includes cable pushdowns and sometimes skull crushers.
From Bodybuilding to Business Leadership
Long before founding Airbnb, Chesky played hockey in college. An injury led him to physical therapy, which sparked a deep interest in bodybuilding. This passion made him stand out when he entered the tech world, though not always positively at the time.
He expressed genuine pleasure at seeing more people in tech now prioritizing fitness and following scientific principles for nutrition and weightlifting. Chesky also draws direct parallels between his bodybuilding discipline and his work in Silicon Valley.
"You don't get in shape from one workout. It's about improving one percent each day," he explained. "The same principle applies in Silicon Valley. Success isn't about a single brilliant idea. It's about grinding consistently, day after day, year after year. What people call overnight successes usually take thousands of days of effort."
The Growing Tech-Fitness Nexus
Far from being an outlier, Chesky's story highlights a strengthening bond between technology and personal wellness. Major AI firms are expanding into healthcare domains. Tech billionaires are making significant investments in longevity research. The intersection is becoming a major trend.
During the same livestream event, Chesky also addressed company news. He discussed Airbnb's recent appointment of Ahmad Al-Dahle as its new Chief Technology Officer. Al-Dahle previously led Meta's generative AI team. This move aligns with Chesky's stated vision of transforming Airbnb into an AI-first application.
The CEO's personal use of AI for health underscores a practical, everyday application of the technology. It moves beyond abstract concepts into tangible lifestyle management. This story reflects how Silicon Valley's leaders are personally integrating advanced tools into their daily lives for better health and performance.
