“I moved here about 9 months ago and got a tad out of shape due to how hard it was to breathe at this altitude. In the past, my husband had done CrossFit, but I had only really dropped in because it intimidated me. But I have loved my experience! The workouts are challenging, but I have seen myself get stronger and feel so much better. All the coaches are always checking in and willing to help with anything from fitness to nutrition. The coaches are so great at making all the workouts obtainable (I super appreciate it).
I actually ended up moving and my new apartment is further from the gym, but I will 100% stick with Colfax Strong because of the community and it is my favorite gym I have been to!”

Kathryn Bolt’s story

“Chad and Esther are some of the most incredible gym owners I have ever had the pleasure of working with. They obviously care about their members and tailor their coaching style to each individual. They put in the time and effort to get to know each individual and help them reach whatever goals they have. I have been doing this style of training for 10 years and this is the best facility I have worked with. They choose each coach very carefully and it shows. I am so happy that I joined this community and feel like along with being welcomed into a family, my fitness has increased greatly! The facility is so clean and the equipment is extremely well taken care of. I love Colfax Strong!!!”

Jacob Henston’s story

“I would like to say thank you! Thank you to Chad, Esther and the Colfax Strong team for everything! The warm hearts while entering the gym, to pushing myself to my limits. I will never forget the people who taught me how to do a push-up, pull-up, deadlift, wall balls-the list goes on! I see the world differently because of you! I just want you to know the impact you made in my life! Thank you again!”
