UnCharted CrossFit®: Opinions
Fantastic experience: I have been doing CrossFit a long time. This facility is by far the best in the area. Huge space, great equipment and enough equipment to allow for large class numbers as compared to other gyms in the area and the best group of people of all abilities, cultures, ethnicities, ages. Family friendly. Great supportive coaching staff. Having been a member at other gyms in the area this is by far the best place to be!
Fantastic experience: Absolutely love training here. Lynette and Chris are both great coaches who coach you up during classes making sure you’re safe but also getting the most out of your workout. They have a great warm-up sequence before the class to make sure you’re prepared for the workout that is scheduled that day. All the members and community are super nice and welcoming and make sure you feel included especially if you’re new to the gym or even just dropping into a class. The vibe is awesome with music choice, gym setup, cleanliness, and a huge amount of space. Highly recommend for all skill levels whether you’re just starting CrossFit or a high level competitor.
Fantastic experience: I visited UnCharted CrossFit with some friends for a drop in class and my experience was great! This is the best box I’ve visited since starting CrossFit almost a decade ago. The members of the class were all very friendly and the coach Darren let me jump right in to their routine based on my experience level. As someone who normally works out at home this place made me change my mind and buy day passes to be part of a community and have access to a fantastic facility.
Fantastic experience: Came by to try it out, had a great time. Coach Darin is awesome, I left feeling great and look forward to going back!

Fantastic experience: This team of coaches and athletes are incredible. Love my crossfit team. I'm working to get healthy again and have found such a sweet community at uncharted. They cheer me on, have been changing my mindset from "lose weight" to "get healthy", and have helped me figure out how to scale workouts to meet me where I'm at physically (while also pushing me to get stronger).
Alyssa, we are so proud of your accomplishments at the gym! We are very blessed to have you at UnCharted and look forward to getting to witness your continued personal growth.

Fantastic experience: Dropping in at UnCharted CrossFit was a blast! The owner, Lynette, welcomed me right away when I walked in and introduced me to the other athletes in class. The community was also extremely welcoming and friendly! The gym is really nice with clean, organized equipment and plenty of space. Lynette’s coaching was top notch, ensuring the class understood all of the movements and scaling options. I will absolutely attend another class at UnCharted CrossFit during my next visit to St. Louis! Thank you Lynette and the UnCharted CF community for having me.
JC, thank you for the review and kind words. Please come back and visit us!
Fantastic experience: The coaches here are so nice and want whats best for you! The receptionists are nice too! I'm glad i started my fitness journey with them.
Fantastic experience: Did a quick drop-in when I traveled to St. Louis for work. The coach and members were super welcoming and accommodating. The programming was great (similar to what my home gym does) and the large facility had all the equipment and space you could need! Would definitely drop-in again if I'm in town!
Fantastic experience: When I lived in Maryland Heights for 6 months this was my first gym to try out in the area. Went to one class and signed up the very next class. Loved my time there and the coaches who cared about your progress and health. Would highly recommend!
Carson! Thank you for the review, we miss you here buddy and hope your doing well.

Thank you for the review Colleen! Your awesome !
Fantastic experience: Great people, great coaches, great equipment.
Thank you Grant! Your one of those great people :)!
Fantastic experience: I dropped in a few times over the two weeks that I was there for training. They were more than welcoming. I have had issues finding a gym recently and they have sparked my passion and interest in CrossFit again. I made new friends almost instantly, was invited to dinner and one of their in house events. They are the epitome of community and I WILL be going back.
Alex this is awesome. Thank you for the review and we can’t wait to have you back!
Fantastic experience: Started CF about 3 yrs ago. I was overweight and thinking I was strong from being a globo gym life member. I immediately had a “come to Jesus” that I had no mobility and my lifts were not proper and even light in comparison. I took a humble pill and gutted through Lynette’s programming all the while she helped my through my journey. More often she made me do much less weight than scaled. I knew I could go heavier but I could have hurt myself and would have hinderd my overall progression. I’ve never been more challenged here second to organized team sports when I was in school. 3 years later I’m stronger, faster, lighter and more mobile than ever before. I’ve went from being intimidated to even judge fellow athletes in the open to competing and eventually taking 2nd in a Festivus games and participating in multiple scaled comps and even getting an Rx comp under my belt. I’ve got a long way to go but in this sport there is no finish line of personal gains. This place has top notch coaches, members and phenomenal space and equipment. I’ve seen many people excel and go past their limits and achieve things they never thought of. A gyms success is not based on how many Rx athletes there are or how many medals are brought home, it’s personal goals and gains. Which I can attest happens here.
Thank you for the review Will. We are so lucky to have you at UnCharted. This is what we strive for. Thank you for being part of our community.
Fantastic experience: Love this place, I have been a member for just over 3 years, and there is no way I ever would have started, or stuck with it this long if not for Lynette and her incredible family at Uncharted. Every week I am challenged to do something new and different and even after 3 years, just this weekend was able to complete a new movement I was never able to do in the past. There is always a variety of workouts and programming which is great because I never get stuck in a rut and I am always able to improve on a weakness. Facility is second to none, coaches are some of the best people I have ever known, community will be my friends for life, and programming keeps me improving. Love this place, thanks Lynette!
Fantastic experience: I started here in February and it has reignited my passion for getting after it! Love the space, coaches, and workouts. I am learning new skills and doing technical movements at higher volumes like hspu, walks, ghd sit ups, pull ups! Just a great environment!
Fantastic experience: Everyone is great here. Prepare yourself for a work out! They even let me try my first class for free.
Thanks for the review Shawn! You are doing great, keep it up!
Fantastic experience: Awesome facility! Tons of space and great equipment! The coaching staff is knowledgeable, welcoming, and encouraging. I would highly recommend Uncharted Crossfit to new and experienced crossfitters.

Fantastic experience: Knowledgeable, caring, World-class staff who genuinely care about their members. You won’t find another gym like this is the area. The members and staff make everyone feel like family. They cheer each other on and push one another to succeed. If you’re looking for results and an amazing atmosphere, look no further.
Fantastic experience: I have been a member of the UnCharted family since day one. I have had many life changes, but STILL COME BACK HERE!! This is my place. The reason? The OWNERS, COACHES, PROGRAMMING, and ZERO JUDGEMENT!! I am pushed EVERYTIME!!! I am greeted with excitmeent, all my questions are aswered, and I have one on one support!! Also, UCCF still beleives in MOBILITY!! Also, the programming!! It is amazing!! REALLY!!! UCCF not only provides CF classes, but SOOOO MUCH MORE!!! We are a family!
Fantastic experience: I can not say enough about how at "home" I feel here. It is not about your size, the amount of weight on the bars, or who you keep up with . . . UNCHARTED is about family and building each other up!!! Coaches ROCK TOO!!!
Fantastic experience: Great coaches and staff!!! Not a nicer facility out there.
Fantastic experience: Very knowledgable staff that helps their athletes work towards their goals. A very large clean facility with a vast array of equipment, whether you join or just are in town for a drop in you won't be disappointed.
