Sauna, steam room & cold plunge — included, steps from the floor.
ONE Boulder Fitness has one of the only full recovery suites inside a Boulder gym — a traditional sauna, a steam room, and a cold plunge, all included with membership. You don't drive across town to recover after training; it's steps from the floor, downtown on Broadway.
Sauna
Traditional dry heat to loosen up after a lift or a long day on the trails.

Humid heat for easy breathing and a full reset — nearly unheard-of in a gym.

Recovery is training too.
For Boulder's runners, cyclists, climbers and skiers, what you do after the effort is what lets you do it again tomorrow. Heat and cold are simple, evidence-informed tools for circulation, stiffness and a clear head.
“Consistent contrast — a warm sauna, then a cold plunge — is one of the easiest recovery habits to actually keep, because here it's ten steps from the floor.— Resident Doctor of Physical Therapy, Atomic PT

Steam room
The one almost no Boulder gym has.
A steam room is a genuine rarity in a Boulder gym. Humid heat is gentler on the airways than dry sauna and a favorite after a hard interval session or a dusty trail day. It's part of the suite — no add-on, no appointment.
Contrast therapy
Hot, cold, repeat — a protocol you can actually keep.
Because the sauna and cold plunge sit side by side, contrast therapy isn't a logistics project — it's a five-minute habit between your workout and the rest of your day.
STEP 01
Warm through
10–15 minutes in the sauna or steam room until you're properly warm.
STEP 02
Plunge
1–3 minutes in the cold plunge around 50°F. Breathe slow; let it settle.
STEP 03
Repeat & finish cold
Two to three rounds. Finishing on cold leaves you alert and clear-headed.
