In abs-olutely great shape! Audrina Patridge flaunts her toned figure as she jogs in nothing more than a workout bra

Very few women would dare to step out wearing just a jogging bra, but Audrina Patridge clearly isn't shy about showing off her body.

The 26-year-old reality star seemed to have forgotten her top as she went for a run today in the South Bay area of Los Angeles.

She flaunted her tanned and toned abs in brightly coloured orange, black and orange Puma workout gear.

Hot bod! Audrina Patridge shows off her toned tummy while running in Los Angeles today

A pair of glamorous oversized sunglasses completed the Hills starlet's athletic look.

She made her way to the beach, where she took a few moments to stretch and gaze out at the ocean.

Her trainer, Jarrett DelBene, recently shared his tricks for keeping the Dancing with the Stars alum fit with Shape magazine.

She does a routine he calls 'body box' two to three times a week.

Really, Audrina? The Hills alum is so attached to her phone that she even jogs with it!

'We alternate rounds of boxing combinations that include punches and kicks with circuits of body weight-only strength moves,' he said.

'It's high intensity, so you burn lots of calories while you're firming up. And because the exercises don't use any gear, [Audrina] can stick to them whether she's on the road or at home.'

One person who appreciates the rewards of Patridge's hard work is BMX biker Corey Bohan.

The couple is gearing up for Valentine's Day, though Audrina at least knows that every day with her boyfriend feels like the holiday of love.

She tweeted to her man last night: 'I spoil you everyday!!!...but vday is extra special :)'.
