Shields is one of only four boxers in history, female or male, to hold all four major world titles in boxing—WBA, WBC, IBF and WBO, in two weight classes.
In a decorated amateur career, Shields won gold medals in the women's middleweight division at the 2012 and 2016 Olympics, making her the first American boxer to win consecutive Olympic medals.[8] Shields was the youngest boxer at the February 2012 U.S. Olympic Trials, winning the event in the 165lb (75kg)middleweight division.[9][10][11] In May, she qualified for the 2012 Games, the first year in which women's boxing was an Olympic event,[12] and went on to become the first American woman to win an Olympic gold medal in boxing.[13] In 2018, the Boxing Writers Association of America named her the Female Fighter of the Year.[14]
Shields was born and raised in Flint, Michigan, where she was a high school junior in May 2012.[9][10] She was introduced to boxing by her father, Bo Shields, who had boxed in underground leagues.[10][16] Bo was in prison from the time Shields was two to nine years old. After his release, he talked to her about boxer Laila Ali, piquing her interest in the sport.[17] Bo, however, believed that boxing was a men's sport and refused to allow Shields to pursue it until she was eleven.[10][16][18] At that time she began boxing at Berston Field House in Flint, where she met her coach and trainer, Jason Crutchfield.[16] Shields credits her grandmother with encouraging her to not accept restrictions based on her gender.[10][19]
