I started coming here around 2013. I moved away for a while, but found myself back at Sanitas and it's still a great gym. Staff and coaching are awesome! Lots of space for classes, and makes it easy to find space for open gym times. Facilities are also top notch.

I have been going to CrossFit Sanitas for the past 6 months. All the coaches are great at what they do. The WODs are well-designed and their individual attention towards every member in group classes helps a lot with learning new movements and improving on basic ones. Crossfit has become a new health staple for me and will be a part of my life for a long time. Thanks to all the fun workouts and people I've met here.

These amazing coaches can lead a class of 3 or 30 with the same level of expertise and attention. They are intentional about getting to know you as a person and also tailoring every movement to your unique ability and fitness level. The approachable programming is perfect for beginners, everyday folks, and if you're an elite athlete, have fun going up against some of the fittest in the area in any given class.

Would give 6 starts if I could. This gym has the highest level coaches around who make the workouts safe and fun. A truly special community who helps you grow both inside and outside of the gym. 100% would recommended!

I have been going to Crossfit Sanitas for the past 9 months and it has been- by far- the best gym I have visited in my 10 year history of going to crossfit. The gym space is clean, huge, open and inviting. Not only is the space great, but the community, coaches and workouts are fantastic- As a physical therapist, I am extra sensitive to proper form, coaching, and emphasis of intensity. This gym excells in everything. I would not hesistate to refer my patients over here for continued strengthening.

At 52, I've never felt stronger or more motivated to continuously increase my strength and fitness. What keeps me coming back to CrossFit Sanitas are the knowledgeable and skillful coaches, a supportive community and a holistic approach to health and wellness. During the COVID-19 pandemic, being able to workout safely five days a week with other people has made all the difference in elevating my mental, physical, and emotional well being.

The coaches at Crossfit Sanitas are amazing. They find a way to give all the members individual attention no matter how full the classes are. The programming at Sanitas has always been intentional and scalable for all ability levels. I love that they offer special Strength and Endurance classes in addition to the daily WODs. I highly recommend checking out Crossfit Sanitas no matter where you are in your athletic journey.

I've tried CrossFit boxes all around the world and Sanitas is hands-down the best I've experienced! The gym itself is spacious and clean, other athletes are friendly and encouraging, but most of all, the coaches are top-notch, prioritizing technique and safety, while ensuring everyone gets a great workout

Had a membership for about 6 months before moving to Denver. It is a great facility that is super clean and also has a great community! The staff are always friendly and welcoming too.

I am late to come for comments, but I am here now! This is definitely a five-star crossfit gym!!! All the coaches are world-class and super nice!!

This is an awesome box! I follow my own programming and found their open gym policy very accommodating. Coaches and members super friendly as well!

Amazing CrossFit gym! The coaches were awesome and focused on getting results in a safe and effective way. I’m only leaving because I’m moving states, but would highly suggest to anyone looking to start or continue CrossFit!

I've been doing CrossFit for a while but was nervous to drop in to a new gym, but both coaches and the members were super welcoming, even at 5am. The coaches made sure I was doing unfamiliar movements correctly and everyone was pushing me through the altitude which I severely underestimated. Can't wait to visit again when I'm in Boulder.

My family and I were in Boulder for 3 days on vacation. I happened upon CrossFit Sanitas, as it was the closest box to where we were staying. The experience was fantastic. Coaches were knowledgeable, the gym is well equipped, the schedule is very accommodating, even allowing for open gym time for your individual programming. They have showers, locker rooms, and plenty of space. The members were inclusive and friendly. The programming was solid. I will definitely return.

Amazing CrossFit gym. The community around Sanitas is strong and friendly. I had no issue connecting with other members and coaches, making the gym experience more enjoyable. I loved the programming, which I thought brought attention to a wide variety of different skills. The coaches are the best around, and are always looking to improve the gym experience for everyone.

This gym is fantastic! The people are friendly, it isn't overcrowded and the majority of people wipe down the equipment so it doesn't feel like a petrie dish.

Their equipment, classes, and set up is great and the overall vibe is perfect for anyone wanting to get a good workout in. Trainers and employees are always helpful and I have had nothing but good experiences!

Throughly enjoyed our time at CF Sanitas whilst living in Boulder. Great space (for kids and dogs too) and equipment. Knowledgeable, qualified, competitive coaches that always have motivating comments. 🏋️💪

Recently finished the on-boarding process for people that are new to CrossFit that goes over a lot of the fundamentals movements with Josh Lee and it was an amazing experience. The first time I met with him he really put me at ease that CrossFit didn’t have to be something scary or really intimidating. I now feel very empowered within that space to continue to grow and become the best kind of CrossFit athlete I can be. I couldn’t recommend CrossFit Sanitas highly enough. For anyone that feels like CrossFit could be intimidating or too much for you, you should totally come to these guys. It’s going to be the best place for you to start.
