Dropped in while visiting KC from Colorado and had an awesome experience. The gym’s in a great spot, super clean, and everyone (especially John) was really welcoming. He even hooked us up with some great BBQ and sightseeing recs! Signing up was easy on their site and they were quick to reply on Instagram for our last-minute drop-in. Definitely recommend CrossFit on 18th Street if you’re in KC!

Did a drop-in here when visiting KC from Belgium. Had a great time with coach John and his Crossfit community. Very welcoming vibe, and an overall great place to get your workout. It was too many burpees, but I'll forgive them for that 😁

Absolutely incredible experience at CrossFit on 18th! From the moment I walked in, I felt welcomed by everyone, the community here is next-level friendly. As someone dropping in from out of town, that made a huge difference.

The coaching staff and ownership are what really set this gym apart. They took the time to go over the entire workout, explained movements clearly, and answered every question without rushing or assuming experience. It’s obvious they care about every athlete in the room, whether it’s your first class or your hundredth.

The gym itself is also top-notch…. air conditioned, spotless, and well-organized. You can tell there’s pride in how it’s run. If you’re local or just visiting, I can’t recommend this place enough. Looking forward to coming back!

I came here for a conference, and found this gym based on walking distance from hotel and positive reviews (including from other visitors). I bought a week visitor’s pass for a very reasonable price, and went to the mid-day classes. John was extremely welcoming, as were the regulars/ members. WODs were fun. If I lived here, I would become a member!

I love this gym and I’m not even from Kansas City! Facility is hands down one of the best CrossFit gyms I’ve been to and the coaches are really knowledgeable.

Since moving to Kansas City in July, joining this gym has been the best decision I’ve made. Working long hours at the hospital, I was eager to find a way to stay active—and this gym has exceeded my expectations in every way. The sense of community, flexible class schedules, and personalized training are unmatched by any other fitness experience I’ve had. Not only have I seen a noticeable improvement in how I look, but I also feel stronger and more energized. This gym is truly top-notch. I highly recommend it—10/10!

This box is truly unique. One of the most incredible places I’ve ever had the pleasure of visiting. The coaches are phenomenal, the facility is gorgeous, and the community of members had me looking forward to each and every workout. The camaraderie within CrossFit is often talked about, but CrossFit on 18th embodies it beautifully. I was only in town for two weeks, and this gym single-handedly made me fall in love with Kansas City. Can’t wait to come back!

I travel quite a bit and get the opportunity to visit many different Crossfit Gyms all over the country. I would rank Crossfit on 18th in the 1% of the 1%. It was super clean.

We dropped in during a visit with our daughter for my birthday weekend. Coach Dana was exceptionally knowledgeable and went out of his way to welcome us and actively coached us through the WOD. He even taught us a few hip opening stretches we had not seen before after the WOD. An athlete in the class ahead of us even stopped to say “hi” on his way out the door. They have outdoor space and great equipment. This has to be the best CrossFit box in KC!

I've dropped into the 11:30am class several times. Fantastic community, coaching, and workouts. Clean showers and bathrooms. Ample equipment and parking. Everyone I met was welcoming and interactive.

I can't say enough good things about this gym. The location was perfect, as there's a coffee spot, a market, and food nearby for post-WOD. The space is amazing and has all the CrossFit equipment you'd ever need. The workout was well-facilitated by the coach- from the warmup to the WOD. There's no doubt CrossFit on 18th has a great community too. I'd particularly like to shout out Dana, who was extraordinarily kind and accommodating. He went out of his way to find a t-shirt for me, even though their stock was basically nonexistent. Absolutely go to this gym if you're ever in KC.

Whether you are interested in getting stronger, losing weight, or making friends, CrossFit on 18th can do it all. Anytime you bring a crew of people together to work ridiculously hard, good things happen. CrossFit on 18th (CF18) workouts often include functional exercises and exercises that mimic movements in my everyday life. Functional movements, such as squats, kettlebell swings, or overhead presses have improved my agility, balance, and flexibility. Did I say I am 5'9" and lost 25lbs right off the bat? Workouts at CF18 have reduced my risk for injury and improved my quality of life. Along the way the friends I am making will be lifelong. We work together, we sweat together, we challenge and push each other to the limit. Of course none of this happens without the incredible dedicated, knowledgeable, and motivating staff that have made our success - their success. Thanks CF18!

This place helps keeps me healthier and happier. The fact that a guy like me with absolutely no athletic background (and 40+ pounds to lose) when I first dropped in has now averaged 4-5 workouts a week here consistently for over 4 years and counting? That says about everything you need to know about the coaching and the community keeping you coming back for more. Coaches John, Brian, Dana, Michael, Kent, Miriam, Cara, Brett, Lauren and Jess -- they're all the absolute best!

Love this gym. I’ve been coming for about a year now and still enjoy it. Before I started coming to the gym, I had always loved cardio, and dreaded lifting. The coaches, especially Brian and John, were fantastic at showing me the correct form for each lift. They are also great about giving you some added encouragement during a tough workout. I’ve gotten more comfortable with lifting, thanks to them. I would highly recommend this gym to anyone. Plus, each class is unique! You will hardly, if ever, do the same workout twice.

Finally decided to make the decision to become serious about working out again, came down to Crossfit on 18th. 56lbs lost and 6 months later I am stronger, healthier, slimmer and happier than ever. Coach Kent, Dana and John have been a massive help. 10/10 recommend to anyone considering.

I joined CF18 about 2 years ago with both bootcamp and CrossFit being totally foreign concepts to me. I think I’ve stuck with it because the classes very seldom repeat, keeping things fresh. I Initially found their jargon and movements to be pretty intimidating, but all the trainers and even other members where eager to help, explain and encourage. The gym has a wide variety of fineness level and aged members. The bootcamp style classes are largely cardio focused and a good starting point. The CrossFit classes are more weight intensive and advanced. Regardless of your starting point. I’d highly recommend you give them a shot for a ever changing workout option.
