[ YOUR COACH ]

HEY, I'M KARYN

My passion started on the soccer field and the cross country course at East Carolina University, where I earned my degree in Exercise Physiology and Nutrition. I've tried it all: CrossFit, bodybuilding, running, obstacle racing. Now I'm a hybrid athlete.

In 2015 I was diagnosed with Crohn's disease and refused to accept it as my new normal. Nutrition and training got me back to a strong, pain-free life, and that's what I build for every athlete I coach.

ATHLETE EXPERIENCES

“Training with Karyn has made such a noticeable difference for me. A 7:30 pace used to feel like an all-out sprint, and now it’s my threshold pace. I also placed 5th in Women’s Pro in my first HYROX Pro Doubles race, which really showed me how much my fitness has progressed.

What I love about Karyn’s coaching is that it feels personal. She doesn’t just give everyone the same program—she adjusts my training based on my goals and what I need to work on. Her app is also really easy to use and navigate, so I always know exactly what I’m doing.

I’ve gotten faster, stronger, and more confident in what my body can do. I’m really excited to keep building from here.”

“Karyn is the absolute best! I look forward to my workouts, not just to stay active but to give my mind a break and have fun.”
