General Manager & Owner

Kyle Fittje

Started at this front desk in 2010. Karie’s call brought him back — first to run the club, then to own it with her.

On the floor, daily

Kyle started at the front desk in 2010 — his first-ever gym job. He left in 2018, looking for new opportunities. Then Karie called him. Not because anyone told her to — it was her idea, start to finish — and it was the kind of call he couldn’t say no to. Karie invited him to help manage the gym and build it into their own vision. He came back as general manager. A couple of years later, he bought in.

Ask Kyle why he’s still on the floor most days, and he’ll tell you: “If I’m not at that club, that means I don’t care.” That’s the whole philosophy. He’ll also correct you if you write “One Boulder Fitness” instead of “ONE” — it’s not a typo to him, it’s the point. All for one, one for all. Everyone in the building, part of the same community. Kyle’s dedicated to a work of passion owning and running ONE Boulder Fitness.
