WHERE SWEAT MEETS STRENGTH & COMMUNITY BECOMES FAMILY

ABOUT CRYSTALLYN KAY'S STUDIO

Founder + Instructor

Hi! I’m Crystallyn — founder of CKS, certified Sculpt and Mat Method instructor, soon-to-be NASM-certified personal trainer, and proof that you don’t have to start out strong to become strong.

For years, fitness felt like a chore. My weight constantly fluctuated, and I never felt fully confident in my skin. I tried everything — but nothing clicked.

That all changed in 2016 when my sister-in-law invited me to a Sculpt class.
It was hot.

Loud. Dark. High-energy.

And for the first time ever… I was excited to move my body.

That one class changed everything.
I started driving to Sioux Falls just to chase that feeling.

Eventually, with a little encouragement from my mom, I got certified to teach Sculpt — just for fun. But the spark grew into something bigger.

In April 2024, I offered my first class in Sheldon. By July, the demand was undeniable — and we made it official: Crystallyn Kay’s Studio was born.

WHY I BUILT THIS STUDIO

CKS isn’t just a place to work out — it’s a place to transform.

I opened this studio because I wanted others to fall in love with fitness the way I finally did — not through pressure or perfection, but through community, confidence, and connection. I wanted people to know they could be strong, powerful, and totally themselves here in Sheldon, Iowa… without having to drive out of town to feel it.

What started as a side hobby quickly became one of the most meaningful parts of my life.

CKS helped me heal. It gave me purpose. And through the support of this community — especially in the hardest moments, like grieving the loss of my mom — it’s become my anchor.
