Recover · Contrast Therapy
Contrast therapy in Boulder — hot, cold, repeat, all included.
Contrast therapy means alternating heat and cold — and at ONE Boulder Fitness the sauna and cold plunge sit side by side, so it’s a five-minute habit instead of a logistics project. Warm through, plunge around 50°F, repeat two to three rounds, finish cold. All included with membership, downtown on Broadway.

Sauna beside the cold plunge
A simple protocol
One routine, three rounds.
02
Plunge
1–3 minutes in the cold plunge around 50°F. Breathe slow.
03
Repeat & finish cold
Two to three rounds; finishing cold leaves you alert and clear-headed.
Because the sauna, steam room and cold plunge are one suite ten steps from the floor, contrast therapy is something you’ll actually do — not a plan you mean to get to.
