What's inside
“One Boulder has been the favorite gym for our company based on accessibility of equipment and classes, and the proximity to the downtown area.”
“Only thing for me is there is no hot tub, but there is a sauna, steam room, and “cold plunge”.”
What climbers say again and again

From the reviews
This is absolutely the gym I recommend when passing through Boulder. You can truly tell the owners love fitness and health. The facility is well kept and the front desk staff are always very professional. The locker rooms are well stocked and clean, the weights are arranged well, and there is ample equipment.
Absolutely fantastic gym! Clean and well maintained equipment at a convenient location. Most notably, the staff are helpfully knowledgable and genuinely friendly!
One Boulder Fitness is a relatively small gym but that is what makes it fabulous, from my first tour through the facility I felt welcome. The gym is never crowded and you can always find a treadmill and weight machines. The small group classes are amazing, especially the Sculpt It! Yoga classes.
I travel around the world and hit a LOT of gyms. This one is outstanding. I use free weights and they have plenty of equipment. The staff is friendly, helpful, and there’s an overall excellent vibe to the place.
