I've used ClassPass to visit CORE Strong Fitness and I've loved them. It's a great facility, offers challenging workouts, and motivational coaches. If you are in the KC area I would recommend checking them out! Adding to my review to share how great the new facility is - I've been attending in person classes for the past year. Walking into the atmosphere at Core Strong KC is unlike any other. It's super clean, organized, and designed so you can get right to business with your workout. I went from attending classes once weekly via ClassPass to becoming a full member and working out with CORE Strong KC daily. The new gym space really puts them over the edge.

I had such a positive experience getting great workouts at Core Strong KC. Mark and crew create a clean welcoming environment. It feels like you’re with family when you’re there. You will be pushed and encouraged without judgement. There is no doubt you will leave sweaty with a smile having made new friends and feeling stronger than when you arrived. Thanks again.

Mark is an amazing instructor and he is supportive in your personal journey to living a happy and healthy life. Everyone in class is friendly and encouraging. Each class is different, challenging and fun. So glad to be part of the CORE Strong Family!

True TRX classes with exceptional coaches and the friendliest, most motivating community in KC. You’ll get results without ever getting bored!

Just attended my first class at CORE Strong Fitness and I'll definitely be back! The atmosphere was so welcoming, and the workout was killer (in a good way!). You can easily modify the movements for your personal skill level, which means people of any fitness level can enjoy the classes. Thanks for the great class!

Mark helped me get strong and fit for a climb to Mt Rainier in the state of Washington. Mark will motivate you and push you to become stronger and will give you the BEST advice on form and posture. The CORE strong family is also very awesome and welcoming!

I have been going to Core Strong for a couple of months now. The classes are challenging and never routine. The coaches will suggest modifications if needed and push you when you need that too! Going to a new gym can be intimidating, but I can honestly say that I have felt welcome from day one. I really enjoy the comradery of the coaches and members. It may sound cliche but this is a gym family, they truly care about one another, not only at the gym but outside the gym as well. Everyone is encouraging and the accountability keeps me going back. My original goals were to get stronger and improve my balance and I’m proud of the progress I’m making.

Queue the theme to “Cheers” cuz sometimes you wanna go “Where Everybody Knows your name!” Like Cheers there is a real sense of community at this gym. I have been attending 3 to 5 times a week since they opened the new facility last year and my transformation both physically and mentally is unmatched from previous regimens. The professional coaching and training I’ve received plus the new friends I’ve made keeps me coming back every week!!

This is legitimately the best gym I have ever visited. The classes, people, and instruction are top notch. As soon as you walk through the door into this inviting and inspiring space, you can feel Mark's attention to detail, care for his customers and dedication to his craft in everything he does. It is truly a community while offering an incredible workout at the same time.

First time going to a TRX class and it was amazing!!! The instruction was spot on, the environment was light and fun, and I got to work at my own pace. Everyone was friendly, I’d definitely recommend and go again! 😁

Very friendly, upbeat environment! Class was hard, but in the best way. You can easily adapt the workout to your level and pace and still enjoy and keep up with the class. 10/10!!!

Nice People. Great workout. I feel like you could bring any skill level and have a good time.

Loved the space and atmosphere! Coach Donte was very engaging and made the workout fun.

Elyse was great! She kept an eye on me to ensure I was always positioned correctly. I appreciated her looking out as it was my first class.

Get your sweat on with Mark, Elyse, or Becca. Everyone is caring, everyone is committed!

I had a great time learning from Mark, and others in the group! It was by far the most exciting and energetic group I have seen yet! If I’m going through Kansas City Missouri again, I will make it a priority to invest in a group TRX exercise. Thanks again for inviting me down there!

Core Strong is the perfect place to get hard, but fun sweat filled workout. I feel comfortable in the huge open air gym space which is nice right now. The coaches are knowledge and offer good variety and encouragement. I highly recommend.

Love this so much!! TRX Straps have taught me so much and improved my overall wellness. I love every class I've taken. Mark and Elyse have been wonderful 👏 . I hope more people find you.

Classes are great -- challenging, customizable, filled with variety, and effective. And the membership is a fantastic value, especially the more classes you attend of course. Finally, Mark does a great job not only leading and educating, but he provides individualized attention, tips, and alternatives. That makes a big difference for me and I'm grateful for it and the results. Can't wait to get another month under my belt!

I’m new to TRX training, but with Mark Campbell’s guidance, I’m getting a good foundation. I’ve attended three TRX/Kettlebell workouts that were killer! Hated and loved every minute of them!

This gym is different then the rest of the gyms I’ve tried going to to get in shape. They have a strong fit family that is caring, motivating and understanding of all goals, fitness levels, and even personal lives. What I love most about core strong is the fit fam that I have there, we’ll hang out outside of the gym and actually build friendships. It really feels like a second home and it makes living a healthy lifestyle and being in shape that much easier! I highly recommend at least trying CoreStrong Fitness at least once!

This place is incredible! The coaches are so knowledgeable, classes are challenging but can be adjusted for all levels, and everyone there is super supportive of each other. Great atmosphere and results!

My experience was great. Mark was a fun, encouraging, and interactive coach. The class was tough but I never felt like I had to push myself harder than I should and was even encouraged to take a break if I needed to several times. Definitely want to go back!

Hands down best gym in KC. The variety of classes throughout the day give you all kinds of options to come in and get your workout. Coaches are all amazing and do a great job not only pushing you but also making sure you are correctly doing the exercise to prevent injury. I’ve been coming here for three years and I have never felt burnt out, always something new you can do to challenge your ability. Facility is clean and very well maintained. Great lighting and a fun filled atmosphere. You come in as an individual and you leave feeling like part of a family.
