Watch Fittest on Earth: Next Gen Online Free on GOKU

Every new generation of champions, from Rich Froning and Annie Thorisdottir to Mat Fraser and Tia-Clair Toomey, has been supported by giants, so if they are able to see farther than their predecessors, it is because they have done so. Fraser opened the door to a fresh round of competitors when he said he will stop competing after the 2020 campaign. The 15th edition of the Games was celebrated in 2021 by both inexperienced and seasoned athletes in 15 competitions meant to test the limits of human potential and determine who is truly the fittest. As she broke records and cemented her spot as the most unbreakable athlete in CrossFit Games history, Toomey persevered calmly and consistently among the shocks, upsets, and breathtaking displays of unmatched athleticism. We saw some of the sport's all-time greats make a comeback at the 2021 Games, as well as the ascent of the newcomers-those who will take on the mantle of the Fittest on Earth for the following generation.
