Little Mix display the results of their intense fitness regimes as they bare their taut tummies in a new fitness shoot

They work hard to keep fit for their high-impact, perfectly choreographed dance routines on stage - and it seems that the Little Mix ladies are reaping the rewards of their gruelling fitness regimes. 

Perrie Edwards, Jade Thirlwall, Leigh-Anne Pinnock and Jesy Nelson display their taut tums and toned legs as they model the new USA Pro range. 

The former X factor winners are so enthused by fitness that they're even getting set to design their own sportswear range with the brand, which will go on sale this winter.
