About Ben Greenfield

Ben Greenfield is a longevity and biohacking expert, human performance coach, and New York Times bestselling author of 17 books, including Boundless and Beyond Training. Ben hosts the Boundless Life Podcast, one of the most listened-to health optimization podcasts in the world, and is a keynote speaker on longevity, fitness, and human performance.

Raised in rural North Idaho, Ben was homeschooled from kindergarten through twelfth grade. He was a complete nerd—president of the chess club, a violinist for 13 years, an avid fantasy writer, and a lifelong bookworm.

Graduating high school at 15 and starting college at 16, he studied anatomy, physiology, biomechanics, pharmaceuticals, microbiology, biochemistry, and nutrition—graduating at age 20 as the top senior at the University of Idaho. He completed internships at Duke University and in the NFL while working as a bartender, trainer, nutritionist, and coach. During college, Ben also served as president of the triathlon club, played for the men’s tennis and volleyball teams, competed in water polo, and was a 215-pound bodybuilder at 3% body fat.

Ben was accepted into six medical schools but chose instead to pursue a master’s degree in exercise physiology and biomechanics. In 2005, he dove headfirst into the fitness world, partnering with physicians to open a series of personal training studios, gyms, and physiology labs across northern Idaho and eastern Washington. In 2008, he was voted America’s top personal trainer.

While building his brick-and-mortar fitness business, Ben competed as one of the top-ranked amateur triathletes in the world, completing more than 120 races and 13 Ironman triathlons. He raced for the elite Team Timex multisport team, won a gold medal for the USA in long-course triathlon, and led squads of swim, bike, and run enthusiasts on guided adventures through Hawaii, Thailand, Japan, and beyond.

After becoming the father of twin sons, Ben shifted his focus toward writing, speaking, and consulting. He launched one of the world’s first fitness podcasts (Boundless Life), became a New York Times bestselling author of Beyond Training and over a dozen other books, and started a blog that now reaches over a million readers each month. 

While making a name for himself as a relentless self-experimenter and biohacker, Ben became a professional obstacle course racer; completed the coveted Spartan Delta; trained with the Navy SEALs; competed across the globe in open-water swims, mountain runs, and adventure races; won multiple USA bowhunting competitions; and appeared on some of the planet’s toughest reality TV shows.

In 2013 and 2014, Ben was named one of the world’s top 100 most influential people in health and fitness. By 2015, he was coaching top CEOs, chefs, biohackers, poker players, and elite athletes from the UFC, NHL, NBA, and NFL—all while advising and investing in leading companies in the health, fitness, and nutrition industries. In 2016, he joined Spartan SGX as a certified coach.

Ben’s expertise in functional fitness, nutrition, and balanced performance has helped thousands—from CEOs and professional athletes to everyday individuals—optimize their health and quality of life. He is passionate about inspiring others to fully experience and joyfully savor God’s creation while pursuing peak physical well-being.

Ben is also a co-founder of multiple leading companies in the health and fitness industry. Among them is Kion, an elite nutritional supplement brand that blends time-honored superfoods with modern science to help people achieve peak performance, defy aging, and live adventurous, fulfilling, and limitless lives. Along with esteemed tech executive Caleb Applegate, he recently launched LIFE Network—a next-generation wellness platform and community that connects members with world-class experts, group coaching at an accessible price, curated health content, and a global network designed to empower transformation across mind, body, spirit, and community.

He also works with corporations and teams on body and brain performance enhancement, specializing in productivity, faith, family, fat loss, digestion, brain health, sleep, hormones, anti-aging, parenting, relationships, mental performance, and overall wellness to achieve an optimized life.

The expertise Ben has spent decades building at the frontier of human performance has made him a sought-after advisor and board member to some of the most respected companies in the global wellness space, including the luxurious St. Haven Clubs by Gurner Group, Next Health, Agentis Longevity, MuseCell Innovations, and Vesalius Longevity Labs.

In addition to multiple daytime and reality TV competitions, he has appeared in and contributed to Forbes, Men’s Health, Huffington Post, Fox News, Triathlete Magazine, LAVA Magazine, and Endurance Planet, and has been featured in WebMD, Prevention, Shape, Men’s Fitness, Women’s Running, Inside Triathlon, NBC, Fox, Entheos Academy, CreativeLIVE, MindBodyGreen, Udemy, Veria Live TV, CBS Sports, MindValley University, and Outside Magazine.
