10. Richard Sandrak
Richard is a young man now, but he once was one of the strongest kids in the world. A son of a world martial arts champion, Richard was born in Ukraine in April 1992, but his family moved to the United States when he was two years old. He also started working out at the age of 2, and by the age of 6, Richard could easily lift a grown man. Nicknamed “Little Hercules,” Richard was able to lift over three times his body weight just two years later which made him the strongest kid in the world at the time.
