For the third year in a row, 26-year-old Rich Froning took home the title of Fittest Man on Earth by putting together another dominant performance in the grueling three-day Reebok CrossFit Games. He put out an especially top-notch performance on Day 3, in which he showed his stamina by winning all three of the day's events, which incorporated everything from deadlifts to muscle-ups to handstand pushups. Froning's mastery of the sport has been incredible, especially considering the unprecedented growth in CrossFit Games participation. More than 138,000 athletes signed up for the event in 2013, compared with 26,000 in the event's debut in 2011. The Games mirrored the growth of CrossFit as a whole, as it continued to grow rapidly in '13, surging past 5,000 worldwide affiliates since it started in the mid-2000s.
