“I just love CrossFit Elm! The coaches are professional and consider your individual needs. The first time I walked in the doors(very scared) it felt like a family! Brandon and Marka have worked hard at creating a welcoming environment in the gym. I have met some fantastic friends along the way.
Come check it out!!!”

“I’ve been to gyms, Orange theory, kickboxing etc., but nothing worked like F45 and kept me as motivated. Tomorrow will be my 100th class and I’m looking forward to more. Thanks for having a great studio, amazing people and a fitness program that sticks!”

“To say I love CrossFit MOB is an understatement. This gym provides such an amazing community full of folks who want to see you grow and succeed in your fitness journey.
The coaches truly care that you move well, and hammer home the fundamentals so that you’re equipped with the building blocks to evolve your fitness.
And all of the people, staff and members alike, are excited to be your biggest cheerleaders and are so inclusive of everyone who bets on themselves by walking through the gym doors.

“These guys have been absolutely fantastic to deal with and be apart of their community. Everyone is passionate and so positive. It’s awesome to be around. My son has been taking classes here for a few months now. All the coaches have been great however a shoutout to Jason is definitely due. He has been so awesome!! How he teaches and interacts is inspiring. The time that is taken to explain things to help insure that the skill being taught is understood and reinforcement along the way. I can’t recommend these guys enough”
“We were looking for a gym closer to home for our son to continue strength, mobility, agility, plyometrics, and speed training between his competitive basketball seasons; thankfully, we found Game Ready Fitness. The classes and instruction, provided by CJ and his coaches, were perfectly geared toward the kids’ abilities and age. The coaches were all very patient and took their time to help the kids when they struggled with correct form; or proper execution of an exercise, and always gave them positive reinforcement. Highly recommend!”
“The community that Mountain Strong has been able to cultivate is wonderful. With many conditioning gyms, it sometimes can feel intimidating but not here. The coaches and owners make you feel part of their family. The members are open, friendly, and the best part, encouraging. The environment here allows your training to feel fun, that's the sweet spot in my opinion. Moving to Colorado and now been here for 2 years, 90% of my friends are from here. The gym always has phenomenal clinics to work on all types of things. From breathing, to climbing knots, to getting your rowing form perfect. They're always getting the community together for fun workouts followed by a relaxing BBQ after. I can write on and one but this place is truly magical. I am so grateful for the connections and life long friends that I have made. This has everything to do with the coaches and owners who have dedicated themselves to creating a place where your health and training can be a happy adventure. Don't get it twisted, they bring it and you will get your pump on but in a fun way.”

“The best Chuze I have been to. I was a part of the morning flow and the staff and fellow gym members were absolutely lovely. Clean and tidy. I constantly saw staff around picking up misplaced equipment, filling wipes and taking out trash. They always did their best to welcome me in and out as well. I moved away but I will always love this Chuze”
“I actually had a great experience at this place. Noah was such a great front desk guy and had great charisma and personality. There's others that I've come across that have been nice or subpar but Noah had a very amazing personality. Very helpful and created great experience!”

“I appreciate the staff enforcing the privacy rules. Fitness content creators should go to a gym with that kind of environment. Not a Planet Fitness that emphasizes no intimidation”

“May 6th 2026 at 5:15 pm I took the STUDIO Flow: Yoga Flow with Shelia. It was intense and I loved it!!! I have bursitis and spinal stenosis. Sheila's class helped me gently work all the muscle groups that my chiropractor recommended I strengthen. I think Sheila's class will help me improve my posture and keep my breathing mindful. I hope this review makes since because I am cooling down from the class before I drive home. My Vasa membership is helping me start my May strong! Thank You!!!! Jodie Buczak”
“I joined this gym recently and have been really impressed with the overall experience. The facility is exceptionally clean and well-maintained, and they have a great range of equipment, so I’m rarely waiting around for what I need to use. The atmosphere is very motivating, and I've found the staff to be incredibly welcoming and helpful whenever I have questions. It’s definitely a solid choice if you're looking for a gym that makes you actually want to show up for your workouts.”
