The first judo school dates back to 1882 in Tokyo. Traditionally a Japanese practice, it has gradually spread across the planet and established itself as one of the world's most popular combat sports.

Literally meaning "gentle way," judo techniques harness an opponent's force to your own advantage by throwing and pinning them to the ground.

Judo was first seen at the Olympics in Tokyo in 1964, and a women's competition was added at the Barcelona Games in 1992.

No judoka has more world championships gold medals than Teddy Riner. In September 2017, the legendary Frenchman won his ninth title, before hitting double figures at an open weight competition in Marrakech.

"It is a sport that demands an irreproachable lifestyle," Riner tells CNN, "a sport that demands rigor."

On the women's side, Ryoko Tani's record stands out. The Japanese Judoka has seven world titles, and upon her retirement was hailed as the "best female judoka ever."
