Ronda Rousey started her fighting career at age 11 when she enrolled in Judo lessons. She became the first American female to earn an Olympic medal in Judo at the 2008 Summer Olympics. In 2012, she became the first female fighter to join the UFC. Did we mention she’s currently undefeated, winning her last match in 14 seconds – the fastest time in UFC history – thanks to her signature armbar move. She had her breakthrough motion picture role in 2014’s The Expendables and also appeared in Furious 7, where she goes punch-for-punch in a high-action fight sequence with Michelle Rodriguez.
