Fitness Hottie Katelyn Runck Gets Steamy In A Colorful String Bikini: 'Back In Paradise'

In her latest Instagram post, Katelyn Runck gave fans some major fitness motivation while sporting a colorful bikini ensemble. On Tuesday morning, the model took to the popular social media app to share a three-photo update that flaunted her toned figure.

In the racy snaps, Katelyn rocked a skimpy string bikini that boasted a blue, orange, and red color scheme. The tiny two-piece left very little to the imagination, showcasing the brunette bombshell's toned arms, massive cleavage, flat tummy, rock-hard abs, tiny waist, curvy hips and booty, and long legs.

In the first snap, Katelyn posed with her hands above her head while leaning against a stone wall. She stood with one hip pushed out, giving the camera a sultry stare. The second shot was very similar, but it was zoomed out a bit to capture more of the stunner's body and surrounding scenery. She also shared a video from the photoshoot, which showed the model running her fingers through her hair while posing in a variety of positions.

Katelyn wore her long, dark brown hair in a deep side part and styled in voluminous strands, which cascaded down her back and over her right shoulder.

She also rocked a full face of makeup for the occasion. The glam look consisted of defined eyebrows, thick lashes, black eyeliner, and pink eyeshadow. She completed the application with a coral-colored blush on her cheeks, a shimmering highlighter on her face, and light pink lipgloss.

In the caption of the post, Katelyn apologized to her fans for the "endless" bikini photos. She revealed that she was back in "paradise," tagging her location as Indian Rocks Beach, Florida.

Of course, the model's 2.1 million-plus Instagram followers instantly fell in love with the sexy snaps. Within 20 minutes of being published to Katelyn's feed, the post received more than 5,500 likes and upwards of 380 comments.
