Testimonials

  • "Love the feeling of accomplishment that working with this crew gives me. The members and coaches are super supportive in getting you your ultimate workout and accomplishing more than you thought you could do!"
    Kris Saprano
  • "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!"
    Wendy Stark Foss
  • "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!"
    Rhonda Rasnick
