“So far, it's only been 2 weeks since I started going to Colfax Strong. I have met Sean, Roman, Esther, and Nick - and they have all been awesome! I was somewhat nervous about trying something new, but it felt right to me -- and I am glad I didn't second-guess myself. It's great gym - close to home, right in the middle of a fantastic community. I wanted to challenge myself to do something new ("if you want something you've never had, you have to try something you've never done" ...), and each time I go to Colfax Strong, II know a little more, and I feel stronger and more confident. On the business side, they have been amazing - reasonably priced with excellent communication. Plus, they are as invested in the fitness journey as I could hope. Feeling pretty great about this decision!”

“This gym is great! Everyone is so welcoming and helpful. The classes are challenging but adaptable for any level. As someone who is often intimidated by group fitness, I’m so thankful to have found a gym that is comfortable, challenging, and convenient.”

“I’ve been going to Duality on/off for about two years. After my prior gym never got its regular scheduling back after 2020/21, it took me a long time to find a new workout space I loved. Duality is truly the best. The programming is excellent, the trainers are all fun, encouraging, and make sure everyone is lifting safely, and the facility is well-managed, clean, and inviting. It’s also super fun that the owners opened a coffee shop/cocktail bar next door (Side Pony) which has helped me meet people and is very convenient for after class! This isn’t just another workout- it is carefully created programming that is always a little different so always engaging. I prefer Circuit classes with Katy who has been so welcoming- always saying hi to everyone and engaging regulars and new members in every class. She has been patient with me through an injury and helped me find ways to still get in a great workout!! ResCon is an amazing low impact workout, too. I have always been particular with the types of workouts I do and balance with other forms of exercise, and Duality is something I look forward to every week!! Thank you guys!!”

“I loved AIR! I wish they would move one to Texas because it was the absolute best. I went to two classes and both instructors were great. I like how they teach one new pose a week.”

“Best place to train in Denver! 5 stars doesn’t do enough to describe how much love I have for this place. They have an excellent training environment whether you want to compete or just do martial arts for fun/get into amazing shape. I’ve been training with them for 5 years and throughout my time here I’ve always had so much support and guidance. I especially love how there is zero tolerance for ego maniacs that try to go 1000% on their training partners. Try out this gym and I promise you’ll be hooked!”

“Best gym I have ever been apart of. They have absolutely everything that you would need, even a sled and tires that you will never find at any other gym. I am very happy being a member at RMFF, and I plan on staying that way throughout my time in Denver. The only recommendation that I would have would to be to shut off the music, or at least turn the volume down. Everyone already has their own music playing regardless, and sometimes it is even too loud to hear through your own headphones. Just food for thought!”

“I’m dropping in from Singapore and never felt more welcome at CrossFit Eminence. Everyone was so kind and amazing! The facility is also really spacious and the equipment is great. I’m really happy to have found this place where I can continue to train happily and safely even while overseas!!”

“Jason is incredibly knowledgeable and friendly. He is extremely enthusiastic and always willing to lend a helping hand and share amazing ideas. His passion for what he does and how he helps people always shines through. I 10/10 recommend Jason and his gym, Icelandic Fitness, for your health and wellness goals. His gym has the best personal trainers and the best Hyperbaric Oxygen Therapy (HBOT) in Denver, CO!”

“Absolutely thrilled with my experience at Crossfit South Denver!I've been attending regularly for over two years, and I can't say enough good things. The coaching from Kyle and Steve is top-notch—they bring an incredible blend of expertise and friendliness that makes each session both challenging and enjoyable. You're not just lifting weights here. You're building an understanding of holistic movement that contributes to your overall well-being.But what truly sets this gym apart is the preventative approach to fitness. There's a distinct emphasis on avoiding injuries, which is a massive selling point for anyone serious about creating a sustainable fitness routine. The programming is intelligent and considers not just strength and agility, but also long-term mobility and health.This isn't your run-of-the-mill gym. It's a place that prioritizes quality over quantity. If you're looking to build a robust, sustainable fitness habit, I couldn't recommend Crossfit South Denver more highly.”

“I absolutely love this gym. I was away from CrossFit (and frankly most resistance exercise) for a few years and was a bit nervous to find a new gym. Lucky for me Cuspis is in my neighborhood, but I can't imagine a better introduction to CrossFit wherever you live in Denver. IMO if you're the sort of person trying to stay fit or get fitter (or even get fit for the first time in your life!) but are nervous about what you might have read about CrossFit in general, give the free workout a shot. The coaches and the other members are both beginner-friendly and you won't feel like you're walking into a grunting meathead factory like at some other spots. People work hard in class, which is part of what makes the place fun & good for you, but nobody's going to make you feel bad for finishing last or using lighter weights.”

“My first class was a free outdoor holiday workout and the next day signed up for their two week trial. Before it was over, I was looking up class packages options and signed up! When I mentioned that I was coming up on my 6 month anniversary to Natalie, she immediately asked “do you feel stronger?” and that is why I love FitCo. The messaging from all of the instructors is not about “earning next meal” or that you can “treat yourself later.” It is about feeling strong in your body, finding your edge and showing up for yourself and the community that Nat and all of the instructors have cultivated. I am excited to see what the next 6 months bring! Thank you FitCo for making going to the gym enjoyable again.”

“StrechLab has been a great addition to my routine. Staying limber is key to balancing athletic/inactive times and avoiding injuries/aches between. Having a trained professional lead the stretching is so much more effective than attempting to stretch on your own. Definitely would recommend StretchLab to anyone that is considering it.”

All of the trainers do such a great job. Janice’s classes have such great energy. Neil really pushes me to improve on technique. I love Monica’s classes and Stephan has such great variety in movements and class formats. Highly recommend joining this gym!”

“My favorite workout in Denver! The team encourages me and I always leave feeling accomplished. A great workout that helps you push yourself past your workout goals, but also makes you feel comfortable modifying as needed. Would highly recommend!”

“This is an equally great place for those with lots of experience and those with no experience! I joined more so for the muay Thai option, but learning KravMaga and jiu jitsu has made a very well rounded and real world application of all the skills being learned. The space is welcoming and I learn something new every class. Also the schedule of class offerings is very flexible and accommodating so it’s easy to go each week. Very happy to have found this place!”

“Lions Den is such a great combination of things. First and foremost the people. Tristan and the team are so knowledgeable and welcoming. The equipment and facility are top shelf. I used to hate them, but the steel maces are becoming a favorite. The programming is second to none.They put proper mechanics at the forefront, and build off of that solid foundation.Look no further wherever you are on your fitness journey. Lions Den SMP is the place to be.”

“This gym has been one of my favorite CrossFit gyms I’ve been to. The coaches are very knowledgeable, know how to modify movements, and are inclusive to athletes of all levels. The warm ups are very extensive to help avoid injuries, and going through the burgener warm ups are so helpful to understand the mechanics of each movement. Definitely a gym I recommend to anyone!”

“Excellent first class. Used to be really into CrossFit, but as I've gotten older, I've slowed down a bit and the CrossFit regimen and intensity didn't get along with my body. This programming seems to capture the quality of workout from CrossFit, without all the uncomfortable competition. Loved it!”
