#7 Ronda Rousey

Tough as nails, Ronda Rousey is best known for her UFC career, where she was a Bantamweight Champion.
But before her UFC career began, she was a highly skilled Judoka. Rousey won a spot on the 2008 USA Olympic Judo team and competed in the Summer Olympics.
Rousey managed to capture the Bronze medal in Judo at the Olympic games, cementing her status as one of the world's elite athletes.
A lot of doubters nay sayed her UFC career before it had even begun, but Rousey silenced her critics with dominating performances and a title run. Rousey often finished her opponents with an armbar submission, which is quite a feat since her opponents were trained specifically to avoid the move.
Then Rousey, a life-long wrestling fan, joined the WWE. After an impressive debut at WrestleMania 34, she captured the Raw Women's title. Rousey is taking a break from wrestling, but it seems likely she will return to the WWE at some point.
Rousey's decision to join the WWE was part of the Divas revolution setup that helped legitimize the company's women's division.
