Fitness Bombshell Katelyn Runck Nearly Spills Out Of Workout Bra In Sultry Update

Fitness bombshell Katelyn Runk put her curves on display Tuesday with a sultry Instagram update. For the post, she wore a workout bra that could hardly contain her assets.

The beauty's green workout bra looked similar to a bikini top in that it featured a triangle design and straps that crisscrossed across her chest. The skimpy number drew attention to her ample chest, which looked as though it was about to fall out of the ensemble. Katelyn paired the top with matching leggings that highlighted her curvy bottom. She also sported a pair of black-and-white trainers.

The busty brunette's update contained three photos and a video of her standing outside in various poses in the outfit. In the first photo, Katelyn was posing in a squat position with her legs slightly spread apart with both hands on her knees. The pose put her chest and chiseled abs on display as she pouted for the camera.

The second snap captured Katelyn from behind as she struck a pose. With one hand on her hip, she looked off to the side as she flaunted her shapely back and hourglass shape.

Another photo showed Katelyn leaning against a wall, while giving her followers a nice look at her toned legs as well as the rest of her fit physique. Her hair was pulled up in a messy bun as she looked at something off in the distance.

The video showed the stunner flaunting her curves in several positions from the front and back, zooming in on her muscular back.

Katelyn wore a light application of makeup that included dark brows and a nude lip color. She also painted a white color on her nails.

In the caption, the fitness model asked her fans if they preferred the front or back view, while mentioning that the active wear was from the brand Ignite.

Katelyn's seemed to love both views.

"You are a beautiful buff toned beast, just breathtaking. DAMN," one admirer said.

"It's absolutely stunning from front to back," a second fan wrote.

"You look amazing in anything," commented a third follower.

"Well... its finally happened... I've now seen the perfect woman," quipped a fourth fan.

The beauty has a body made for figure-hugging workout clothing and skimpy bikinis. That being said, she also knows how to rock all kinds of looks, including sexy dresses. She likes to keep her 1.5 million followers guessing at what she will post next, but they can almost always bet that whatever she decides to put on her body will look fabulous.
