Having had multiple surgeries and no physical therapy over the years, my body has taken a beating. I'm thrilled with the supportive training at KJ! In a few short weeks, I'm feeling the progress. Kristy is helping me keep my mobility and build to something better.

This place is incredible. I am new-ish to Colorado and new to Hyrox; I learned that KJ offered Hyrox-specific classes and so was able to prep and train for my 1st race, which proved to be invaluable. Em and Tim both taught fantastic classes, and tailored the workouts so that I could practice and improve in the specific Hyrox challenges. It made for an amazing 1st time race for me, in which I felt ready and prepared to meet the challenges head on. So thank you, KJ! Can't wait to come back and continue to train.

I was facing challenges with a heart condition but didn’t want to give up working out. Kristy made it possible for me to keep training safely while my doctors worked on a solution. She expertly modified my programming to ensure I could continue making progress without overstraining my heart. Thanks to her guidance, I hit PRs on nearly all my olympic lifts!

I can’t recommend Kristy and the coaches at KJ Health Collective enough. Their experience, knowledge, and personalized approach allow them to meet you exactly where you are and create a clear path forward. Whether you're navigating an injury, a medical condition, or just looking to improve your fitness, they will help you succeed! Thank you Kristy and the staff at KJ Health Collective!

KJ is an awesome gym. I had never done an crossfit class before and their coaches made sure I understood each exercise and helped me make adjustments to meet me at my level. Every workout is unique and keeps you on your toes. If you are consistent the changes in strength are noticeable and fast. Every coach i’ve trained with has been motivational and educational. Highly recommend 💪🏻💪🏻💪🏻

TL;DR: A great place to begin (or continue) a journey to a better life.

I'm an older guy (50) with typical older guy problems and no history of playing sports or working out -- let alone CrossFit -- before starting at KJ in early 2021.

I started at KJ to support my son as he ramped up for Navy boot camp. It's been over a year now and I'm at KJ four or five days a week, doing CrossFit, StrongFit (strongman/woman stuff), and Olympic Weightlifting. So I came here for somebody else, but stayed for myself.

I'm still that older guy and this is still hard work, though. I scale workouts most days, but the coaches are ready with ideas for how to keep that challenging, and they drive me just as much as they do the amazing athletes that have been here a while.

And that covers the community and the overall experience here -- we push and encourage each other, again and again, until it's over (for that day, at least) and we can't believe what we've accomplished.

This sense of satisfaction started me actively thinking about how to align the rest of my life for better results. This led me to fix my diet and sleep habits, which in turn led to better workouts and opportunities beyond exercise that I couldn't have predicted.

Now I'm in the best shape of my life and I'm not done, and I owe it to the people at KJ and one simple rule -- show up and do your best, whatever that is. If all that sounds like your thing, I recommend you come here and do what I did.

As for my son, he's now a corpsman (medic) in the Navy, on his way to working with the Marines and a career in medicine. My daughter is headed for the Navy in four or five more years and is already joining me at KJ a few days a week.

I can barely keep up with her sometimes, and I don't mind.

I wasn’t sure about doing the CrossFit at first. Everyone at KJ made it a no brainer to stay. In my early 40’s and I’m stronger than I’ve ever been, feeling great. All thanks to the amazing coaching staff and the fantastic people that go to this gym. It’s a great community filled with fantastic people who are passionate about improving themselves, and it’s infectious. I can’t ever go back to a normal gym.

KJ has been such a blessing!
Moving to Colorado I knew it would be tough to find a new gym even comparable to our “home” gym in FL.
But KJ has some of the friendliest people, and coaches that take the time to get to know you.
There’s a variety of classes, 7 days a week.

I was new to CrossFit when I started at this gym and I was super intimated to try the sport. The coaches and community at KJ are amazing. The coaches pay close attention to form and keeping everyone safe. For new movements, they take the time to teach and never made me feel silly for asking questions. Their support continues to push me to achieve new personal records in a fun and safe way. The rest of the community there is supportive, inclusive engaging, and always cheering each other on! Such an amazing time. I have been going for over a year and a half and still LOVE it. It continues to be challenging and I am amazed at the results. Highly recommend!!!

The trainers at KJ Crossfit are some of the best trainers in the industry. They are very knowledgeable and do a great job of coaching/teaching everyone from new beginners to seasoned athletes. The environment is very encouraging and has a fun competitive nature. There is a strong emphasis on doing all lifts/movements correctly and safely, therefore, I have seen very few injuries. The community at KJ is not like any other gym I've seen. The friends you create at KJ are lifelong friends. This is one of the best Crossfit gyms in Colorado!

KJ is not just a great and safe place to learn Olympic weightlifting, gymnastics, and other CrossFit moves - it’s a community. The owners, Jeremy and Kristy, have built a community that cares deeply for each other, supports each other’s goals, and is always there to cheer you on. This is true both inside and outside the gym. The coaching is top notch, the class selection is vast, and the members you’ll get to know will become extended family. All shapes, sizes, and ages are welcome. One of the things I like best about KJ is the overwhelming support to scale a workout to ensure safety and the ability to workout again the next day.

We tried every gym in Boulder County it felt like and Kristy and Jeremy create an amazing environment to get fit. The coaching lineup is top notch! Olympic Weightlifting sessions are fire with several of the coaches having a speciality in those specialty movements. Skills classes are awesome, I always learn something new and am given appropriate drills for my current level. I always feel safe in what’s being asked of me in any workout and am challenged without being shamed for not having any particular skill.

The community is first rate and have felt so welcomed! There are always fun activities and seasonal get togethers and the KJ crew make everything fun!

I also really like that they respect peoples privacy. No crazy data use policies you have to agree to to be a member. If you ask not to be photographed they are really respectful.

Look no further. This is your gym. Sign up here and never look back!

The impact that KJ crossfit has had on my life is unbelievable. I came into the gym as a novice athlete. The coaching and support I have received to grow physically is unmatched compared to any other gym I have ever experienced. Not only are the coaches well-educated and pay special attention to each athletes’ technique, limitations, and adjustments that are needed; but they (and the entire gym community) are also the most supportive people you could have cheering on your accomplishments as you grow in your fitness career. I went from barely being able to handle a barbell to competing in a crossfit and Olympic Lifting competition, and striving to perform my best and grow in my workouts each and every day.

Not only will KJ crossfit provide the space and support for you to be better physically, but you will also find a home here. I am proud to say that this amazing community has become my friends and my family. They have become a central consideration in my life and my days are significantly better when I walk through those doors.

If you are searching for a place with an amazing community, full of genuine hard-working people, that will encourage you to be the best that you can be physically — then please come to KJ crossfit and see what it is all about. It has truly been one of the greatest blessings in my life.

When you walk into KJ, you know the workout will be tough (but can be modified). Expect that the coaching will be on point, and know if something isn't right with a movement, both Kristi and Jeremy will do anything to fine tune it so you can get stronger. The programming is the best around without a doubt. I've witnessed new people walking into the sport, and in a short amount of time, they are killin the workouts, lighting up the board. I've seen such great gains in myself and look forward to my workouts there everyday. I have recommended KJ to everyone and will continue to recommend everyone to join.
