One Directionare preparing for their upcoming 10-month long world tour in a big way. In addition to vocal warmups, rehearsals and sound checks, the band are getting in shape -- and getting some more moves besides "the Joe" to add to their arsenal.

That's right: 1D are taking Zumba lessons!

The Sun (via SugarScape) reports that the adorable Brits, who make no secret that they're not the best dancers on the planet despite being the biggest boy band on the planet, are trying to get fancier footwork for their tour.

“The lads are not natural movers so them dancing to Latin music is a sight to behold," a source said. "But they know it’s good for fitness so they’re putting in the graft.”

In addition to the Latin dance moves they're learning, the band are also taking part in spin classes. They may already be fit and gorgeous -- look at them shirtless, for Heaven's sake! -- but we support their ambition to keep getting better.
