The song was co-written by singer-songwriter Lucie Silvas, Charlie Russell and Mike Peden.
It was showcased during Liberty X's sold-out arena tour in early 2003, quickly becoming a fan favourite.
[1] "Jumpin'" was one of the first songs to be recorded by Liberty X following the release of their debut studio album, Thinking It Over.
Tony Lundon told Newsround: "Jumpin' we chose as a single because it just worked well on the tour and it's the kind of song we want to sing.
The music video for the track was filmed in an underground arena, depicting the band held in cages, and dancing on a circular platform.
