Fun fact: Laura Zeng became the first U.S. rhythmic gymnast to win a medal at the Youth Olympic Games when she nabbed an all-around bronze in 2014. The U.S. has never medaled at the Olympics in rhythmic gymnastics, but Zeng, a 2016 Olympian, hopes to change that this year. She's off to a good start: Zeng was part of the team that secured two Olympic rhythmic gymnastics spots for Team USA, the first time that's happened since 1992.
