Morgan leads with confidence and creativity. Her classes are high-energy but grounded, and she knows exactly how to get the most out of you. Whether you’re sculpting or stretching, she’s your girl.


"Hi, I’m Morgan Winkel! I’ve loved health and fitness since high school, where I was a four-sport athlete. Through college and beyond, I stuck with at-home workouts—but I joined CKS for a change of pace, and instantly fell in love with the energy, people, and atmosphere. Every workout made me feel stronger and prouder. Becoming a group fitness instructor was never in the plan, but it’s been one of the best decisions I’ve made. I love helping others believe in themselves and realize they can do hard things. At CKS, there’s no competition—just community and support. A fun fact: I just got married in June 2025! My husband Brandon and I have a red lab named Axe."

I’m married to my husband, Robby. We have three children, Haley, Cael, Bree and a son in-law Damon. "

Calm, centered, and deeply intentional. Kate’s yoga classes are your space to breathe, soften, and realign. She brings peace, power, and grounding to every session.


"Hey, I’m Kate and I teach traditional yoga at CKS. I started teaching in order to better treat and advise clients on gentle stretches/relaxation after their massage appointments. Of all the fitness modalities I’ve tried, yoga is the one I come back to. Discovering the mind body connection and being able to achieve peace and calm while exerting energy is truly transformative. I enjoy seeing the yogis who attend, experience their own form of harmony in this safe and supportive environment."

The queen of the burn. If you love a challenge, Renee’s classes are where it’s at. Her combos will light your core up — in the best way possible.


"Hello, my name is Renee Bork. Fitness has always been a huge part of my life—from playing sports throughout school, serving in the Army Reserves, to running a couple of half marathons. What I enjoy most about instructing and being involved in fitness is how it makes both myself and others feel—not just physically, but mentally as well. I love that no matter what class I teach or join, there’s always an incredible mix of support and sweat! A unique detail about me: I was born six weeks premature and weighed just 4 pounds, 6 ounces."

Erica brings unmatched energy to every session. Expect a fun, focused workout that challenges you to level up and leaves you feeling unstoppable.

"Hey there, my name is Erica Koedam. I have been a group fitness instructor for almost five years. I recently moved to Sheldon from Rock Valley and live with my boyfriend, Heath, and between the two of us, we have five wonderful kids, Kellen, Evie, Brea, Islie and Memphis. To me, group fitness is more than just a workout. Working out with others at CKS creates a shared energy that motivates and inspires everyone in the room. Knowing I get to create that space where people can reconnect with themselves and feel supported by others is the most meaningful part for me as an instructor. I am so grateful for each and every member at CKS!"
