Earlier in the day the Burlesque star spent time with a personal trainer as part of her daily work-out regimen that has seen her running, boxing and doing step training in a effort to get her body in perfect shape ready for the start of filming.

On this particular day Julianne and her trainer cycled bikes down the Miami beach board-walk.

In the film, which begins shooting in Miami next week, Julianne plays Sherrie, a small-town girl who moves to Hollywood in pursuit of a glittering acting career but ends up working at a bar owned by Dennis Dupree, played by Alec Baldwin.

Movie highlights are set to include Julianne’s scenes with ’bad boy rocker’, Stacee Jaxx, played by Tom Cruise, who her character has an affair with.

Rock of Ages will be the second movie that Julianne will star in after completing work on the new version of Eighties classic, Footloose.

Julianne Hough still found time to fit in a session with her personal trainer who took her on a bike ride down the beach

Footloose was her first lead role in a movie, reprising the role made famous by Lori Singer in the the 1984 classic, which propelled its star Kevin Bacon into the limelight.

Julianne, who made her big screen debut in last year’s Burlesque, says fans will get to see a new side of her.

’People are going to see my performance rather than the glitz,’ she told USA Today.

’This is hometown-girl hot. I’m definitely wearing some tight jeans in this movie.’

But whether the remake can match up to the magic of the original - which launched the career of Kevin Bacon - remains to be seen.

The update of the iconic 1984 dance flick will open in October with a new cast including professional dancer Kenny Wormald, who takes over Bacon’s role of Rem MacCormack.
