Ben Greenfield was raised in rural North Idaho and homeschooled from grades K-12. He was a complete nerd. He was president of the chess club, played violin for 13 years, wrote fantasy fiction and spent most of his childhood years with his nose in a book. Ben graduated at 15. He began college at 16, playing singles and doubles for the men’s tennis team.
For four years, Ben studied anatomy, physiology, biomechanics, pharmaceuticals, microbiology, biochemistry and nutrition, eventually rising to the top of his class, completing an internship at Duke University and the National Football League. He then graduated in 2004 at 20 years old as the top senior in his class at University of Idaho – all while working as a bartender, personal trainer, lab assistant, nutritionist, spinning instructor, athletic trainer and strength and conditioning coach. While attaining a 4.0 GPA in his advanced science courses, he competed as president of the triathlon club, middle for the men’s volleyball team, hole set for the water polo team and was a muscle-bound bodybuilder at 215 pounds and 3% body fat.
Ben was then accepted into six medical schools, but opted to instead attain a master’s degree in exercise physiology and biomechanics. Afterwards, in 2005, he leapt into the fitness world, partnering with physicians and opening a series of personal training studios, gyms and physiology and biomechanics labs across North Idaho and Eastern Washington. In 2008, he was voted America’s top personal trainer.
While building his empire in the brick-and-mortar fitness industry, Ben competed as one of the top ranked amateur triathletes in the world. He completed over 120 races and 12 Ironman triathlons and raced for the elite Team Timex multisport team, winning a gold medal for the USA in long course triathlon. He also led squads of swim, bike and run enthusiasts in guided adventures through Hawaii, Thailand, Japan and other countries.
Eventually, Ben became the father of twin sons and pivoted into media, writing, speaking and consulting. He launched one of the world’s first fitness podcasts, became a New York Times bestselling author of “Beyond Training” and 13 books, designed and created the Christian Gratitude Journal, and started a blog that now reaches over a million rabid fans each month. During this time, while making a name for himself as a relentless self-experimenter and biohacker, Ben became a professional obstacle course racer, completing the coveted Spartan Delta, training with the Navy SEALs, competing across the globe in open water swims, mountain runs and adventure races, winning multiple USA bowhunting competitions, and appearing on the planet's toughest reality TV shows.
In 2013 and 2014, Ben was named as one of the world’s top 100 most influential people in health and fitness, and by 2015, Ben was coaching the world’s top CEOs, chefs, biohackers, poker players, tennis players, motocross and endurance competitors, and professional athletes from the UFC, NHL, NBA, NFL and beyond – all while advising and investing in top companies in the health, fitness and nutrition industry.
