She fell in love with the CrossFit community within Impact and enjoyed her improvements and gains and how much these components helped her triathlons.

Crossfit Athlete
Mother of 3 adult kids and more pets than I care to admit
Lover of red wine and Doritos
I began my endurance journey at 40, and after a decade of distance running, I added in weight training. The results were transformative: my running improved, my mood lifted, and my overall health soared. Noticing a gap at my gym for a beginner's weight training class, I pursued certifications and launched one myself. Now, as a woman over 50, I love nothing more than seeing a gym or box full of women lifting heavy! As an endurance athlete, I’ve experienced firsthand the incredible benefits of combining strength training and mobility work with running, no matter the level.

ANDREA RENDON
Originally from Colombia, Andrea found her first Crossfit gym when she came to the United States in 2011. Coming from a background in a variety of sports (Volleyball, Ultimate Frisbee, Underwater Rugby), she was looking for something fun but that would keep her healthy, active, and competitive. After a short time, Andrea realized Crossfit offered so many challenges in different aspects of fitness that it was exactly what she had been looking for. This realization opened the door for a new found passion of helping others through fitness. For the past 7 years Andrea has worked as a Crossfit and Nutrition coach, both with group classes and tailoring programs to individuals who have more specific goals. The enjoyment she has helping people improve and reach their goals is just as exciting as reaching her own.
When not in the gym Andrea spends most of her time in the water playing and competing in Underwater Rugby and Underwater Hockey.

EMIR DEDIC
CROSSFIT COACH
Emir discovered his passion for fitness later in life, beginning with endurance running—not just marathons, but ultra-distance events that took him all the way to completing 100-mile races. After moving to Colorado and balancing life with kids, he expanded his athletic pursuits into climbing, archery, and other mountain sports that matched his adventurous spirit.
During the COVID lockdown, Emir turned to functional fitness at home and quickly fell in love with both the movements and the methodology. That passion led him to join Coal Creek CrossFit in 2022, where he has continued to grow as both an athlete and a coach. Emir holds a CrossFit Trainer Online Level 1 certification and brings a well-rounded, lifelong approach to fitness.
He lives in Superior with his family and is dedicated to helping others discover their own strength and potential.
