Form & Fire was created to be more than just a workout.

It’s a place to move with purpose, build strength, and leave feeling energized, confident, and on fire from within.

I’ve always lived an active life. Fitness has been my outlet, my confidence-builder, and something I’ve returned to through every season.

But one heated workout class changed everything.

The heat. The music. The challenge.
I walked out feeling accomplished, empowered, and completely on fire.

That feeling stuck with me. It sparked a passion that led me to become an instructor, helping others experience that same strength and confidence through movement. When life brought me to La Crosse, I fell in love with the community, but felt a void. There wasn’t a studio that combined heat, intentional movement, and connection in the way I had grown to love.

So I created it.

Form & Fire is my way of bringing that transformative experience to La Crosse. A space where you can show up as you are, work hard, and leave stronger inside and out.

Let’s have fun & workout together!

HEAT IS OUR ELEMENT.

The heat is what sets Form & Fire apart.

Our heated environment helps:

  • Warm up muscles quickly

  • Increase flexibility & mobility

  • Enhance strength & endurance

  • Create a deeper mind–body connection

More than that, the heat creates an energy, a sense of focus, release, and accomplishment. It challenges you in the best way. It leaves you feeling strong, grounded, and more accomplished than ever before.
