This year’s Olympics will, for the first time, feature breaking – a style of street dance that originated in 1970s New York City. It’s characterised by acrobatic movements, speedy footwork and a hip-hop soundtrack. More than 30 breakers from all over the world will compete.

Rachael Gunn, known as Raygun, from Australia, is one of them. Raygun explains the rules and tells us what she loves about the sport, and why it’s so physically demanding. William Lee Adams from the What in the World team chats about the sport's history. And BBC Sport Africa reporter Isaiah Akinremi explains what else to look out for this year — including an Opening Ceremony on the River Seine.
