During our visit to the area, my teenage son and I had a fantastic time at CrossFit 904, where we were welcomed by friendly staff, attentive coach, and well-structured workout made us feel welcomed and motivated, leaving us excited for our next visit!

Super friendly and welcoming place. I had so much fun doing one of their partner classes! Definitely was sore the next day!

Great gym, but please be careful bringing your husbands to this CrossFit gym. They sell shirts seasonally, and my husband refuses to take it off/retire it. He got this shirt probably in 2021.
To the owners, please for the love of god and CrossFit, tell me where you got these shirts so I can finally get him a new one.

I’ve been going to this gym for a year now, i started with no CrossFit experience. Immediately the coaches and members were so knowledgeable, welcoming and encouraging! I’ve gained strength and confidence and a wonderful community of amazing humans.

Crossfit 904 made the hunt for a new gym super simple. One class was all it took and the need to look elsewhere disappeared. I’ve been attending for a couple of months now and I can honestly say the coaches, community, and workouts are awesome.

I’ve been to a few CrossFit gyms, none have been like CrossFit 904. The coaching and members are amazing!

I joined 4 months ago and it has been great! The coaches here are amazing and really care about you moving safely and improving day by day. They take their time going over all the movements. Everyone is so welcoming at this box!

I feel like I can give some unique insight into Crossfit 904 as a company given my relationship with the gym. I work out of Crossfit 904 as a physical therapist so I get to experience the day to day differently than an employee or an athlete. This gives me the opportunity to see all the things that make the gym great that most will not get to see. Michael and Erin have a true passion for building the best Crossfit Gym in Jacksonville. Every decision they make is based on serving their community and building a gym most clients call home. It is amazing getting to see all the time and effort making renovations, effort they put into creating great coaches through deliberate hands on coaches throwdowns, and all the work that goes into putting on an amazing Friday Night lights. If you are looking to join a Crossfit gym in the Jacksonville area, I think it is a no brainer!

I started at crossfit 904 over 6 months ago. I have never tried crossfit and wanted a positive community experience at a new gym. 904 hit all the marks! The coaches and owners take so much time to teach all levels of each skill and progress you only when you're ready. The members are all so encouraging and will cheer for you, and build you up, when you need it the most. An amazing experience so far and I'm excited to see what the new year brings!

CrossFit 904 is by far the best CrossFit gym in Jacksonville! From the community to the programming, no gym compares to this box!

Awesome CrossFit community! Dropped in with the super-convenient weekly pass and was immediately embraced by the friendly CrossFit 904 community. The community here is extremely friendly to newcomers and is both warm and welcoming. Erin and Michael do a great job- highly recommend!

Just joined about a month ago and already feel like I’m part of a family as well as getting the best workouts I’ve ever experienced. Coaches/owners/staff are absolutely incredible and so intent on each individual person in the gym and their goals. So happy I joined!!

My wife and I have been going here for 2 months and it has been great. We both had no experience with CrossFit, but the coaches have been extremely helpful in their instructions and guidance. The community there is great and as scary and intense as Crossfitters seem, here they are friendly and encouraging!
