    What do people say about us?

    • I was member of Crucible Crossfit while living in Jacksonville and cannot speak highly enough about box. It is the perfect combination of a box that pushes you to be your best, has the full range of wrap around services (physical therapy, nutritional education, and specialty coaching), expert coaches, and welcoming environment. You can only go right with this team.

    • Every one there was really welcoming and awesome! Colleen is so knowledgeable and helpful. I wish we had more time to spend there and lift and play with all their equipment. Super fun box , really nice people, all around great experience! Definitely would return if ever in the area again!

    • I dropped in for a busy Friday 3:30 class, Colleen and Lance were more than accommodating and welcoming. Lance was patient with me, and helped improve my form on several exercises. I look forward to coming back the next time I am in Jacksonville!

      Marco Martino
    • I love dropping in here when I visit my friends in Jacksonville. I joke often with my wife that we should to Jacksonville just to be able to go to CrossFit Crucible. The coaching is always impeccable and the people are kind and fun to exercise with. It is one of my favorite CrossFit gyms I’ve ever been to!
