The legend goes that Khabib Nurmagomedov grew up wrestling wild bears in the mountains of his native land of Dagestan, overseen by his martial arts mentor, his father. Except, it isn’t just a legend. It is real, and we have footage of it. He had a pet bear -- still does, apparently -- and wrestled the bear throughout his childhood, building the wrestling skills, stamina and legendary toughness for which his countrymen are famous in the wrestling world. He also went on to become a two-time Combat Sambo world champion before transitioning to professional mixed martial arts (MMA).
