Jim and I have been with One Boulder Fitness since its inception. We are big fans of the gym, its trainers and its staff. They work hard, keep things clean and are always helpful. Much thanks to them all, especially Karie, Kyle, Hannah and a big shout out to Andre, who helps with speed and a smile.

Great experience so far. Definitely not an Equinox but has everything you need and is very clean. Weight room is larger than it looks, providing ample room for busy days.

I recently started going to One Boulder Fitness, the amenities were super nice especially the sauna. Sharoon at the front desk was very knowledgeable and helpful. He addressed everyone coming in by name which added a great sense of community. Can’t wait to start coming more often.

great club...have been working out here for a number of years. Started going early post pandemic and the morning staff is great...especially Andre who is always upbeat, friendly, knows my name, asks how I'm doing, and how my workout was.
