Every year, the Reebok CrossFit Games claim to crown the Fittest Man and Woman on Earth—a bold statement, to say the least. But it’s hard to imagine a more comprehensive test of strength, conditioning, and mental fortitude than the four-day, 14-event slugfest that kicked off on Thursday, August 2 and ended Sunday, August 5.
