  • "Great coaching! Excellent community! Could not ask for a better crossfit experience."
    Todd Hicks
  • "I feel blessed in many ways to have found this box. I was pretty intimidated by things I had heard about CF, that is until I started my training and actually spoke to the coaches and saw first hand what a great group of people workout here. It is by far the best of the best that anyone at any level could ever hope for. CFU coaches are all excellent and very helpful in all realms of life!"

  • "I could not have been more scared to start crossfit 8 months ago... and I never thought I'd be able to stick with it. CF Undeniable changed all that for me! I am so grateful to have found such a wonderful gym. The coaches are AMAZING - everyone truly cares about your performance, your form, and you! On top of that, the community is one I never dreamed of. This is definitely my "home" gym and I look forward to going for years to come. Thank you Zac and Karly for your commitment to this wonderful gym, this is the first time in my life that working out is an enjoyable part of my life and not a chore. =D"

  • "This is a quick "thank you" for letting me drop in, unannounced, to workout with my daughter yesterday. Great workout and adjustments for my limitations. Glad she now has a box family of her own!"
