Your whole fitness team, under one roof in downtown Boulder.
ONE Boulder Fitness is a downtown Boulder gym where your workout, your recovery, your physical therapist, and your dietitian all live at one address: 1800 Broadway. Train on the floor, recover in the sauna and cold plunge, rehab with a resident Doctor of Physical Therapy, and fuel with a resident Registered Dietitian — without driving to four places.
Train
An open, non-intimidating floor — free weights, cardio and a functional area — with nine certified personal trainers who program around your life, not a template.
A sauna, a steam room and a cold plunge — included with membership, steps from the floor you just trained on. Almost no other Boulder gym has all three.
A resident Doctor of Physical Therapy practices on-site through Atomic PT — sports rehab, climbing and running injuries, dry needling — down the hall from where you train.
A resident Registered Dietitian practices on-site through ActivEnergy — performance nutrition, healthy aging and body composition, aligned with your training.
Standard membership includes a free consultation with a trainer, physical therapist, or dietitian. It's the easiest way to meet your team and map a plan — no upsell required.
Here's why one roof compounds. You train with a coach who knows your goals. When a niggle shows up, the resident DPT is down the hall — not a six-week referral away. Your dietitian sees the same training load your coach programmed. Recovery isn't a separate errand across town; it's the sauna and cold plunge ten steps from the floor.
Four specialists, one building, all talking to each other. That's the difference between a gym membership and a transformation.
Are the physical therapist and dietitian included in membership?
Your membership includes a free consult with a trainer, PT, or dietitian. Ongoing PT and nutrition services are booked with the resident practices (Atomic PT and ActivEnergy) — we'll connect you directly.
Can I see them without joining the gym?
Yes. The resident physical therapist and dietitian see clients who aren't gym members. Being a member simply makes it seamless — everything's at one address.
Is everything really at one location?
Yes — the gym floor, recovery suite, resident DPT and resident RD are all at 1800 Broadway #190 in downtown Boulder.
