On Friday, personal trainer Katelyn Runck provided her 1.4 million Instagram followers with some fitness inspiration.

The photos show the fitness model standing on a beautiful outdoor patio surrounded by green foliage. In the first image, Katelyn posed with her shoulders back, as she gazed seductively into the camera. For the following picture, the beauty showed off her sculpted arm muscles by putting her hands on her head and leaning against a door frame.

Throughout the photoshoot, the stunner sizzled in a white, asymmetrical sports bra and matching skintight leggings from the clothing company, Elisabetta Rogiani. Katelyn flaunted her fit physique in the revealing workout gear that put her incredible curves and washboard abs on full display.

The brunette bombshell styled her highlighted hair in tousled waves. She enhanced her gorgeous features by wearing a full face of makeup, an application that included glowing highlighter, nude lip gloss, and voluminous lashes. Her long nails were also perfectly manicured and painted a soft pink.

In the post’s caption, the social media influencer announced the launch of her fitness app, On the Go. She noted that those who download the app will be given instructions for numerous workouts. In addition, the model went on to explain that focusing on fitness has positively impacted her life. Katelyn revealed when she worked as a runway model she weighed only 90 pounds, standing at 5 feet, 10 inches. Eventually, however, she was able to work on both her mental and physical health through exercising.
