  • "I've worked out at a lot of gyms over the years, but I've never found a better fitness experience than CFU creates! Different every single day, CrossFit works out your entire body and builds your strength, fitness, and confidence faster than you would believe. No matter your current fitness level, the CFU coaching staff works incredibly hard to make the experience fun, safe, and challenging! Don't start tomorrow...come in today!"

  • "Great gym, and even better people to run it. I would recommend this gym to anyone and everyone."
    Lewis Turner
  • "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!"

  • "The coaching staff are awesome! As a drop in I felt very welcome and comfortable working out in a new environment! Loved how encouraging everyone was! Definitely know where to visit when I'm in Colorado."

  • "After moving to Westminster 4 months ago I was nervous to start at a new crossfit gym but everyone here was extremely welcoming. I have definitely come to love the group of people here. The coaches have already made me stronger and are always pushing me to go further. CrossFit Undeniable is great!"
