One Direction have reportedly taken up Zumba classes to get in shape for their live shows.
The boyband - Louis Tomlinson, Liam Payne, Harry Styles, Zayn Malik and Niall Horan - begin their world tour at London's O2 Arena on February 23 as well as performing at the Brit Awards next week, and so have joined the dance and fitness class in a bid to get fit, The Sun reports.
A source said: "The lads are not natural movers so them dancing to Latin music is a sight to behold. But they know it's good for fitness so they're putting in the graft."
1D won't actually be showing off their dance moves on stage - just their trademark jumping around to their tunes.
But trainers have still added morning spinning classes to their fitness regime.
The boys have also been warned off late night partying, drinking and smoking by their management to ensure they are in peak physical condition for the 100 date global tour, which will last ten months.
