So far one of the best crossfit gyms I have been to! Colleen and Lance are very motivating for every workout you do they make sure you understand their technique workout I appreciate you both thanks for having me at your gym.

This is an absolutely fantastic gym the owners are very knowledgeable and have a comprehensive set of skills and certifications that allow them to create top notch programming. The gym members are friendly, and it is structured without being rigid. There is ample equipment to go around.

Ive been working out here 4 months now and am really enjoying it! This is exactly what I needed to have happen for me right now. I couldnt be happier.The programming is hard but manageable. Everyone is friendly. The facilities are nice with several bathrooms and two showers. Theres the main room for class, and a back room for side work and additional equipment. And when its nice out, theres plenty of space outside (& minimal traffic) to spread out!Ive also been dealing with injuries off and on (no, not CrossFit related. Everyone assumes that.), and the coaching staff has no hesitation when offering me another modification. Its hard to find a reason to skip when theyre so accommodating!I highly recommend stopping by and seeing what its all about!

Best box ever! I am a 59 yr old female with no athletic background and receive excellent coaching (very patient!!) Coaches were just as excited about my first 20 in box jump as someone getting their first muscle up! Colleen and Lance are the best and can scale anyone for any issue - So glad I found them! The members are awesome, great group of people - so glad I found them.

Beware of this place they will not cancel your membership and will continue to charge you even after they say they they are going to stop. My husband has asked them numerous times to cancel his membership and they continue to charge us $100 a month even though he hasnt gone since November. I have opened a dispute with my credit card company in hopes that they will stop. Look below, other reviewers have had the same problem.

Phenomenal box! Fantastic coaching. The gym has all types of people. Elite, teenagers, regulars and new crossfitters. Each workout can be modified to your ability. During the entire 3 years that I have been a member, I get as much one on one coaching and attention as the most elite athletes in the box. Lance has been a loyal and positive motivator without judgment. On any given day, he helps us give it all and become better versions of ourselves. Crucible or bust!

Crucible CrossFit is one of the most fundamental expressions of the CrossFit methods you can find in Jacksonville, FL. Crucibles coaching staff is incredibly knowledgeable, humble, and compassionate. The facility is large and well equipped with any piece of strength & conditioning equipment needed. The programming is solid and community is tight. Crucible CrossFit is a fun place to make friends and get stronger -- check it out!

Love working out here. The trainers do a great job of breaking the movements down every do. This is one of the best priced CrossFits i have found in a while. Great people!

This place is hands down the best CF box in town. Great coaches, great atmosphere, and the best programming. Couldn’t recommend more!

I waited for months for this relationship to get better before writing this.The facility: actually pretty good in terms of space and location and was the sole reason I decided to join.The clients: some elite athletes, and certainly some new friends. But it seems everything is geared toward the elite and not necessarily the new people.If the above is what you need/want then you should adjust my rating up, however I will not ever recommend this facility to anyone for the following reasons.The facility: Bathrooms are not clean, and there is clutter everywhereThe Owners/Partners: I wasnt able to attend as much as I would like so I cancelled, after verbal notification, written notification, recorded notification, multiple Facebook conversations and 9 calls to the number on the website (I guess not their number)... I continue to get charged my monthly membership. I have since investigated with my local attorney a way to try and correct this behavior for others and I am leaning toward letting my bank resolve the dispute at his recommendation but part of me wants to make an example out of this gross neglect.My advice if this is the closest, most convenient location (the primary reason people go there) then buyer beware, and keep logs of everything.I have written dozens of stories of locations that are exceptional, and owners who care. This isnt one of those.

Exactly what you would expect when you go to a crossfit box. They have amazing coaches, great athletes and stellar programming. Ive dropped in a few times now and have always left completely gassed. Cant wait to come back to town!

Great box, great people! I had to come back to Jax for the day and wanted to get a good workout in... And I definitely did. Drop in here if youre in the area!

Love this place, the owners and coaches and their programming. Will not find better in Jacksonville. (Or any other place for that matter)

Tired after every workq
