COLLECT - Olivia McCuish - Age 6 - 2019 - Junior World Champion. An eight-year-old girl has won THREE world titles in taekwondo and set her sights on Olympic gold after taking up the sport to help calm her rage. See SWNS story SWSCchamp. Olivia McCuish started taekwondo aged just three and flew up the ranks - training alongside adults by the time she was five. Proud mum Emma, 42, said Olivia would use her stepbrother Kristopher, 17, as a punching bag growing up. Health and safety manager Emma stared taking Olivia to taekwondo classes after she became frustrated with the lack of conversation with the kids in her nursery. The youngster has worked her way up to a red belt in the sport - just one step below a black belt. Olivia used lockdown to focus on her taekwondo, training every single day in the spare room which her parents turned into a gym.
