The 2016 Reebok CrossFit Games were a grueling five-day, 15-event test to find the fittest man and woman on Earth. "Fittest on Earth: A Decade of Fitness" follows the dramatic story of the top athletes who qualified and competed and offers an inside look at what it takes to be among the world's elite athletes, both in training and on the competition floor. The CrossFit Games challenge competitors to perform intense physical tasks, but the hardest part is sometimes mental. Athletes often learn the details of the events only minutes before they begin, and everyone handles the pressure differently. Which of these fierce competitors will rise to the top and earn the title of Fittest on Earth?

In 2017, the fittest athletes on Earth took on the unknown and unknowable during four of the most intense days of competition in CrossFit Games history. "The Redeemed and the Dominant: Fittest on Earth" captures all the drama as the top athletes resembling chiseled Grecian gods descend on Madison, Wisconsin, to face a series of trials. Hercules faced 12; they take on 13. Emotions run high as a throng of Australian athletes rise to the top. By the end of the competition, some learn tough lessons - that all that glitters isn't gold, or even bronze - and some learn that they're even stronger than they realized. The best among them enter the pantheon of the CrossFit giants and earn the right to call themselves the "Fittest on Earth"

From Rich Froning and Annie Thorisdottir to Mat Fraser and Tia-Clair Toomey - if each new generation of champions sees further than the one before, it's because they stand on the shoulders of giants. When Fraser declared he would retire from competition after the 2020 season, he opened the door to a new wave of challengers. In 2021, new and seasoned competitors marked the 15th year of the Games with 15 events designed to test the limits of human potential and their worthiness to be called the fittest. Amid the surprises, upsets, and staggering displays of incomparable athleticism, Toomey ticked on with consistency and calm like a clock in a thunderstorm, all while shattering records and securing her place as the most unbeatable athlete in CrossFit Games history. At the 2021 Games, we witnessed the return of some of the sport's greats and the rise of the new initiates - those who will carry the mantle of the Fittest on Earth for the next generation.
