Boulder's Only Cold Plunge


Personal Training:

Come to the WODs every week and you’ll be a CrossFit star in no time. But if you’re looking for more one-on-one attention to focus on particular movements, or ramp up your training for a race or competition, our CrossFit coaches are here to help at your convenience.

Contrast Immersion Therapy, Showers, Locker Rooms

CrossFit Sanitas is the first gym in Boulder to offer a Cold Plunge Pool and accompanying hot rain shower, the perfect antidote to sore muscles. Contrast Immersion Therapy, alternating cold and hot water following a workout, can reduce soreness and improve recovery times by 20% or more. The cold pool and hot rain shower are available to our members at no charge.

We also have full shower facilities and lockers available.


We understand athletes! Weekend warriors to professional athletes can expect our massage therapists to provide more than a typical Sports Massage. We’ll customize your sports massage treatment plan, educate you on your imbalances and demonstrate stretches & strengthening routines. Visit our Massage page for more details or to book an appointment online.


Nutrition is the foundation of any effective fitness program, and is an equal partner to workouts, recovery and sleep in CrossFit’s equation for optimal fitness.

We carry a variety of healthy food options on location including local, grass-fed meat from Locavore Delivery, Alaskan wild-caught salmon, local eggs, paleo snacks and pre-made Paleo meals.
