Bradford teacher Nikki Yellop is the unseen talent behind Britain’s Got Talent winners Spelbound.

The 36-year-old PE and performing arts instructor at Tong High School is the top acrobatic troupe’s choreographer.

The mind-blowing stunt routines (right) that catapulted the gymnasts to TV success is all down to Nikki who will be joining them on the show’s national tour starting this week.

She said: “School’s been great giving me time off, although I won’t be away on tour all the time. Spelbound is quite a talking point!

“I keep telling the students these gymnasts aren’t superhumans, they just work hard and are dedicated to what they do. It’s a good lesson to learn.”

“When we got on the show all we wanted to do was get our kind of acrobatic gymnastics noticed. We want it to be an Olympic sport – now there’s even talk of us being part of the London 2012 Olympics opening ceremony.

“We weren’t sure what kind of response we’d get from the public when we went on the show but it’s been phenomenal.”

And she said Spelbound had been inundated with calls from gym clubs around the country who are suddenly getting more members – especially boys – signing up.

“It’s fabulous it’s becoming so popular and cool. It’s a fantastic response,” said Nikki who retired from acrobatics when she was 24 to become a choreographer at the Heathrow Gymnastics Club where she trained and was home to Spelbound.

“I’ve got to admit when I watch them out there I’m wishing I was with them. It’s an amazing opportunity and they deserve everything it brings them. They train 20 or more hours a week and fund it all themselves.

“There’s no money for acrobatic gymnastics, so even those who represent their country in the world championships have to pay for it all, even down to their Great Britain tracksuits!

“We’d love it if acrobatic gymnastics became an official Olympic sport and if we could say we helped make it possible. It’s not just beams and bars.”
