I dropped in from out of town for Thanksgiving and was immediately greeted and welcomed. The box is extremely clean, organized, and spacious. Josh, the owner, was professional, friendly, and brought effortless energy to the class while making me feel right at home. The workout was great, the community was solid, and I’m really glad I stopped by. I’ll definitely be back the next time I’m in town!

I dropped in while traveling, and it was an absolutely fantastic experience. The coaching was top-notch! clear, attentive, and genuinely focused on helping everyone move better and get the most out of the workout. The facility itself is spotless and organized, with plenty of space and all the equipment you could need.
What really stood out was the crew. From the second I walked in, everyone was incredibly welcoming and fun. The energy in the room was contagious, and it felt like I’d been part of the community for months, not minutes. If you’re looking for a place with serious coaching, great vibes, and a super supportive environment, this is the spot. Can’t wait to drop in again!

Joined CrossFit Millstone at the end of June 2025 after taking quite some time off of CrossFit. I am SO happy I enjoyed CrossFit Millstone because the gym, coaches, workouts and building have helped me find my love for CrossFit again! The community is so welcoming , and filled with people of all ages and levels of fitness! Instantly I could tell that community means ALOT to the owners and members , & that’s so special and rare , and very important for a gym!! The coaches do a great job helping you push yourself when you need a push or modify when you need to modify! The building is big, clean, organized! Love that it is family owned by husband and wife! Highly recommend CrossFit Millstone

Long time member here, but was reminded once again this morning as to why this gym is so amazing! My daughter and I attend class almost daily, but she showed up today limping due to an extremely tight and painful calf muscle. Coach Josh recognized her issue immediately and curated a specific workout targeted to her injury. He then spent 1:1 time with her, even personally rolling out her calf to try and provide her some relief from her pain. She ended up walking out with no limp and a significant reduction in her discomfort. This personal attention to her situation just proves how much the coaches truly care about the well-being of all of the members at CrossFit Millstone and I am so appreciative of their commitment to our health and fitness!

I’m new to CrossFit and dropping in while traveling. I’m so glad I came to this gym! Josh was incredibly welcoming and made me feel comfortable even with my limited CrossFit experience.

What stood out to me was how supportive the environment was. There were people of all experience levels. Everyone was friendly and encouraging — which really helped push me through those last few seconds of rowing.

Josh took the time to check in with me and make sure my form was solid. One day was front squats. Another day was push press. I appreciate how attentive he was making sure I was doing things safely and effectively. His energy and motivation definitely helped drive the whole class.

The facility itself is super clean and I loved the open garage doors — it gave the space an awesome vibe! Overall, such a welcoming and positive experience. Whether you’re brand new or experienced this feels like a place anyone could feel comfortable and challenged. Thanks for making my drop-in week so great!!

Large gym, all the good equipment, great staff are all big things for this place but I also love the flexibility of full membership down to pay on the spot drop in sessions and punch cards for those that sometimes can't commit to the fulltime.

I was in town for my son’s baseball tournament and had a couple of great workouts this past weekend. The husband-wife team that runs CrossFit Millstone were extremely welcoming and seem to have a true passion for fitness. The gym was spacious, clean and well organized. I’d highly recommend CF Millstone!

I joined Millstone recently after my previous gym closed and I have been so warmly welcomed by all at Millstone and challenged in a positive manner since days one. The equipment is of high quality and the gym is very well maintained. Whether you are looking for a full Crossfit community or just a place to be fit, Millstone is a great place to be.

CrossFit Millstone was overly welcoming. They welcomed me after my current gym closed down and was looking for a new gym. They made the transition so easy and made me feel like home. I owe them so much for making this transition as easy as possible.

Before joining Millstone, we hadn’t been a member of a gym in a very long time. I craved feeling stronger and challenging myself and my body in new ways again and I knew I was going to have a hard time getting there without some form of support. In 2024, after carefully considering lots of different options, I finally called Amber U, signed up and I’m so glad that I did. It’s such a welcoming space. There is no toxic fitness culture vibe at all. All of the trainers and the other members are so welcoming, encouraging, and supportive. They will truly meet you where you are at, offering endless modifications to make sure you can safely engage with the exercise, while also challenging you to reach your potential.

We are beginners and one of my initial worries about group training was not being able to keep up. But that’s not an issue at all. I’ve never felt rushed or like an inconvenience if my pace was slower than those around me. That continuous positive encouragement from Josh C, Amber U and all other coaches and members is helping us to achieve more every day.
There is so much variety in the training, and you’ll never do the same workout twice! I really love this aspect of the experience. I’m so glad to be part of this community.

CrossFit Millstone has changed the way I view CrossFit. When I first started, I was extremely intimidated and nervous, but the coaches showed me it was possible to start slow. The community is very supportive and friendly. I look forward to each class, knowing that I am able to work at my own pace. Overall the perfect gym for beginners and experienced athletes.

Best gym out there in the Quad Cities area! Super accommodating to people just starting to learn CrossFit and the lifting moves. The coaches mentally keep track of your individual progress to make sure you’re getting a challenging workout in. They are incredibly kind, clean, and kid friendly. More recently, they have gone above and beyond with my pregnancy journey swapping out workouts that work with my growing bump, work with me to make sure I’m comfortable, still getting a challenging workout in and still allowing me to feel included in the class with everyone else.

The coaches and other members genuinely make you feel welcomed. Great atmosphere no matter where you’re at in your crossfit journey they will push you to be better all while building you up.

5 out of 5 stars. ⭐️⭐️⭐️⭐️⭐️

an amazing gym! i have been to multiple gyms, including other CrossFit gyms and none are comparable. Millstone is always clean and tidy. All of the machines work, and all of the equipment is in excellent condition. and the FLOORS, the floors are always clean, which is a huge plus when you’re face down doing burpees. Not to mention all the coaches and other gym members are super helpful and friendly.

Did a drop in class at the gym, and this is a fantastic upcoming Crossfit location! The facility itself is very nice and has been updated well, stocked with top of the line fitness equipment and has a great environment.

Even more important, they've got great coaches who really care about their members, and are well on their way to building a great new CrossFit community! Definitely worth your time to stop in and try them out!
