Welcome to ONE Boulder Fitness, Downtown Boulder’s favorite health and fitness club. Here, you matter most.

Since 2005, OBF has been serving the community as secret gem hidden in downtown Boulder. Members come for the location, and stay for the community. Where front desk staff know your name, squat racks rarely have a “weight” time, and lifelong friendships have been born simply from seeing the same friendly faces every day, we pride ourselves most on the creation of close, tight-knit feeling in the heart of bustling Downtown Boulder.

Everything you need, nothing that you don’t.

We are proud to offer you a versatile weight room, a Boulderite-friendly cardio room, a multi-purpose studio, loaded locker rooms with showers and full towel service, and our fan-favorite co-ed spa area with a hot tub, steam room, and sauna. With flexible membership options to choose from and ZERO contracts, we can be your home gym for the day or a lifetime. Feeling unsure? Try us out with a complimentary visit.
