Yorkshire lads Liam Richards and Danny Ball, who made it through to the final show of last year's Britain's Got Talent and were watched by 15 million people, were at Harehills Primary School.

The two performance martial artists were watched by a stunned crowd of kids as they back-flipped, kicked and leapt their way through a breathtaking routine.

Their explosive performance combines different styles of martial arts, acrobatics, gymnastics and dance, all choreographed to music.

And since appearing on TV the lads say they have been getting more involved with spreading the messages of focus and discipline they have learned from martial arts.

Liam said: "We're just trying to motivate and inspire them and give the children something to aim for. Also we want to make them aware that if you out a lot of work into something you can achieve it."

Strike toured with the Britain's Got Talent finalists around 22 venues in the UK following the TV show, performing to thousands each night.

Danny said: "We're loving working with kids and we've been doing it since we were young. Now we've been on TV that's given us a great outlet and made it easier to get the message out there."

Liam added: "We learned martial arts when we were at school and it helped us because it teaches you to focus and discipline – a lot of the things you need in school."

Strike were brought to Harehills by Shaun Weatherhead, who runs personal development enterprise U Can Shine. He met Strike at a local martial arts club and invited them to come to the school.

He said: "This is the first school in the area they have done but we are looking to get them involved in more schools."
