Fit couple: Tamra and husband Eddie Judge got cozy as they posed for a photo shoot earlier this week

Yesterday, the Bravo star shared a behind-the-scenes image of her and Eddie getting cozy for a fitness photo shoot. The pair own their own gym, CUT fitness.

'Fitness shoot with the hubs,' she wrote, flashing her toned figure in skimpy pink shorts and a blue sports bra.

Tamra has focused on an intense fitness regime as she works to fulfill her dream of competing in a bodybuilding contest.

Last week, she shared a snap of her toned legs as she teetered in sky-high, clear plastic heels.

Sky high: 'Don't be jealous of my fancy shoes,' she wrote as she practiced walking in heels ahead of Muscle Mania on Sunday

'Don't be jealous of my fancy shoes,' she wrote.

'Practicing my walk .... 5 days,' and added hashtags ''#musclemania' and '#fitmom.'

Two weeks ago, Tamra also shared a snap as she posed next to surfboard and got ready to strut her stuff onstage with the help of bodybuilding coach Mia Finnegan.

'Caught you looking at my curves!' she wrote.

'Posing class with @mia_finnegan. Wait until you see what's happening with this surfboard on May 28.'

Her trainer Mia, a former bodybuilding world champion, told Bravo's The Daily Dish that Tamra had been 'skinny fat' before they began whipping her body into competition shape.

'When we started she was skinny fat. And she knows it,' Mia said.

Strike a pose: Tamra's body has undergone an amazing transformation as she prepares to fulfill a lifelong dream and compete in a bodybuilding contest

'She's small, tiny. But not a lot of muscle. There was muscle under there, but she had quite a bit of body fat on top.'

'Just to watch the transformation, even today, she has a crazy schedule. She's a mom of four and to watch her be so dedicated and so disciplined to her nutrition, her supplements, her family obligations, her work obligations, her gym obligations, and she's doing it.

And Tamra gave an update on her progress last month, saying her workouts had been 'brutal.'

'Down 11 pounds of fat - up 11 pound lean body mass,' Tamra revealed. '18% body fat. Less than 5 weeks to go. Gotta lower that body fat... @mia_finnegan gonna be a brutal 4 weeks stay away from me if your smart (sic).'

Sharing a bikini photo two weeks ago, the 48-year-old admitted she didn't feel ready.

'Less than 3 weeks away and I feel far from ready. It's crunch time baby,' she wrote.
