- "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"
