10 Olympians who have competed in the UFC
#3 Ronda Rousey
Ronda Rousey became an inspiration to thousands even before she made her name as one of MMA's greats. As a child, she suffered a speech impediment because she was born with the umbilical cord wrapped around her neck.
Her father committed suicide when she was 8. "Rowdy" fought through the tribulations and at 17, became the youngest Judoka in the history of the Olympics when she participated in the 2004 Summer Games. Four years later at the Beijing Games, Rousey became the youngest American woman to win an Olympic medal in Judo.
Rousey made her professional MMA debut in 2011 and won all her first eight fights via armbar, including two against Miesha Tate - one to claim the Strikeforce Women's Bantamweight belt and a defence of its UFC equivalent.
Rousey's record for most title defences in women's weight classes still stands today. She also has the most armbar finishes in UFC/Strikeforce/PRIDE/WEC history and the second and third fastest title fight finishes in UFC history.
Rousey won the ESPY for best female athlete consecutively in 2014 and 2015. She married fellow UFC fighter Travis Browne earlier this year, breaking Derrick Lewis' heart in the process.
