Great facilities. Excellent coaches. So many classes to choose from (even on Sunday mornings).

For me this is the best fit CF gym in Boulder. It's the biggest, the most convenient class schedule (earliest and latest, and nearly every hour), and the best variety (strength-, flexibility-, teen-, women- and endurance-focused). Unlike other Boulder gyms, they have "open gym" as long as the facility is open. It's more relaxed than other places (your "score" doesn't go up on a board), and the coaches are there to give you constructive criticism, not yell at you and provide your motivation for you. If you want an ultra-competitive gym, to feel like you're working out in a warehouse, or an intimate 6-person class, this isn't it.

Dropped in for a workout while out in Boulder for work. I have done CrossFit several times but tend to stick to my orange theory and pure barre workouts where they don't make me sling around heavy weights ;) so I was a little rusty.
The staff here was so friendly and very welcoming - asking me about myself and continuously giving me pointers on form. They were genuinely invested in my workout. And the workout itself was really fun and definitely a great workout. I highly recommend this gym. I imagine being a full time member is awesome

This gym is totally phenomenal. The coaches go out of their way to help anyone regardless of where they are at with their physical fitness.

Dropped in here and I gotta say really great coaching with patience and attention to details. Went thru everything thoroughly from start to cooldown. Will come again!

I'm new to CrossFit and am a way out-of-shape, overweight, 40+ something. Despite this, I have received nothing but support and encouragement from the staff here. Granted, I may not make the time goals for a workout session, but I still get thru them. Does anyone mind? NO!
They give nothing but support and will tailor your workout to meet your needs, yet challenge you to get better at the same time. If you are an overweight, out-of-shape 40+ person like I am... this is the place to go to, to make your life healthier!
I've already noticed a difference after my first week here! Nobody at Sanitas judges you either. There's people here of all ages, fitness levels, shapes & sizes. If you want a positive and supportive place to make your health and body better... this is the place to go! :) I wish I would have found this place sooner.

Great CrossFit gym with excellent coaches. Huge locale with lots of equipment. Does not feel crowded even with 20+ people joining a class. Centrally located in boulder. Easy to park.

The whole vibe is positive, fun and motivational. The workout is intense more than I'd ever do on my own. and very effective. The staff is so friendly and welcoming.

The coaches are some of the best in the nation and most of them compete at the regional level. They coach focusing on form/technique, improving while not getting hurt and and having fun. The facility is one of the nicest and cleanest you'll ever see and it's 10,000 DW. Ft. It's also one of the cleanest gyms I've ever been to.

Top that off with really great friendly members and you know why they are a top 5 gym in he nation.

Sanitas is unique. Instructors are knowable. Members are consistent with very low attrition. The owners understand the importance of the customer, and by the enthusiastic atmosphere and approach to classes the employees are treated right. Sanitas is a fun place to workout and hangout.

A CrossFit box is only as good as its coaches, and Crossfit Sanitas is really spoiled when it comes to coaching and programming. Our coaches are friendly, focused, supportive, and deeply knowledgable. The vibe of the gym is laid-back. We have some very fit athletes, but the environment isn't intimidating. It's welcoming to members, newcomers, drop-ins and CF vets alike. But when the bell rings and the work starts, we get after it. Sanitas has created a culture of encouragement and support among the athletes and coaches. We work hard, but we have fun. At Sanitas, we're as happy for the PRs and improvements and victories, large and small, of others as we are of my own.

Second time trying cross fit and this place made it enjoyable. The instructor walks you through the movements which was great. I've noticed people don't really wear shirts here.

This gym has some of the most knowledgable and patient coaches I have ever encountered. Beautiful gym with wonderful people in it!!!!

Sanitas is an outstanding box in all aspects. The coaches (instructors) are knowledgeable, supportive and technical experts. The facility is the nicest, cleanest CrossFit you'll ever set foot in. Management actively solicits member feedback and promptly acts on suggestions. There's a wealth of nutrition, lifestyle and wellness information provided weekly (including frequent seminars with world class physicians and authors). There are multiple class tracks for those interested in specific focuses (strength, endurance, mobility, etc.). And the community of members are inspirational and quick to embrace new athletes. You won't find a better place anywhere to workout than Sanitas.

Friendly & knowledgeable coaches. Lots of variety in workouts. Tons of open gym time. Members become friends outside the gym. Classes all day long. A very supportive community.

Second time trying cross fit and this place made it enjoyable. The instructor walks you through the movements which was great. My only complaint was that people need to learn what a shirt is.

I'm really loving my membership at Sanitas. The staff is smart, friendly and enthusiastic. I've taken classes/been coached/been worked on by Dwight, Tom, Jake, Mike, Laura, Antonio and Elisa directly and have had positive experiences with all of them. Something I really enjoy is the community and camaraderie built through the group workouts. The only ego in the gym is your own. Check it at the door and work out as hard as YOU can and you will see results.
