“Everything about this gym is special - the classes, instructors, staff, and studio are all absolutely amazing. I could not recommend a gym more. Kondition has provided me an amazing community that I love so dearly and reignited my passion for fitness. THE BEST!!!”
“Our family was in Boulder on vacation and I just dropped in to CrossFit Sanitas randomly. They were incredibly welcoming and let me know all the things needed before the workout started. Dwight was so knowledgeable and Tyler was very thorough, dedicated to the class schedule, and above all else encouraging and quick to point out correct form and technique.
I would highly recommend CrossFit Sanitas to anyone!”

“I love love love this pilates studio. The instructors, music, vibe, class variety (cardio, pilates, and combo!) are all wonderful! I look forward to these classes every time. The studio is always clean, they have a shower and towels and snacks/drinks for purchase. They've really thought of everything for creating an amazing space forMy one issue is the stringent policies and archaic way of booking/lack of rollover and limited flexibility around it makes it really difficult to understand how many classes you've paid for and when you can book out (I think it is 2 weeks out), to the point that I've dropped my membership due to work travel and inability to come as consistently. I say archaic because you dont have access to see on the Mecha Studio app what classes you have leftover, but need to use the mindbody app instead. The mindbody app isn't great (and this isn't mechas fault!) but needing to use two apps to be on top of rollover is another step and leads to confusion and frustration when, at the end of june, you're sitting on classes you paid for but aren't able to use.They roll over classes up until June and then again December, which is definitely more than some of the other local studios. Anything you still have left you aren't able to use up (aka, lose it) What is bothersome is are not able to see this on the mecha app, but instead need to go into the mind body app to have an idea of whats still available.You aren't able to freeze your membership and use the classes either, so the policy is strict, and there doesn't seem to be any wiggle room at all. The staff have communicated that this is manual, which I can imagine is quite frustrating for them. If that is the case, is it possible to make exceptions or send out comms around this in the future (Friendly reminder to check Mindbody for any classes as any unused will not roll over as of June 30?) For it to be manual for the staff and for the guests, perhaps considering an email reminder to everyone about this.I would love for the studio to reconsider this policy for continual rollover, or update your own app so that this is more transparent and you can book and see availability in one spot and you do not need to go back and forth with someone via email.”
“Congratulations to CrossFit Roots on 17 years!
I've been a member for over three years now, and it has genuinely changed my life. The persistent back and knee pain I dealt with for years is virtually gone, and I'm stronger than I've ever been.
I still remember my first day walking into Roots. I was incredibly intimidated, and many of the movements seemed impossible. But with great coaching, patience, and consistency, I've learned, developed, and accomplished things I never thought I could.
Most importantly, this gym is truly for everyone. Every age, every fitness level, and every body type. The coaches meet you where you are and help you become a better version of yourself.
I'm incredibly grateful to be part of this community.
Congratulations on 17 years, and thank you for the positive impact you've had on my life.”
“Great staff. Full racks. Barbells. Hex barbell and lift platform for DLs. The only glaring issue with this place is the number of people who workout and walk around the entire time barefoot or in socks! Barefoot at a rack or on lifting platform makes sense, but barefoot on a cable machine? Yiiiiikes!”

I love the community that Connie has built and I look forward to seeing everyone each time I go. I started going for shoulder rehab and general injury prevention and it made a huge difference in my recovery. I have never been a gym person but I do love going to the ATC!”

All coaches are great and coach Courtney is the absolute best.
I highly recommend Orange Theory to everyone.”

“I've been training at this gym for just over three years. In that time the facility has continually improved and adapted to the changing needs of its members. The coaching staff is incredibly professional and knowledgeable, helping me to secure a national championship in my sport while improving my overall health and performance. I've been to just about every strongman gym in Colorado and Gym 5 is by far the nicest, with just about everything you'd ever need for comp prep.”

“Great programs for all ages!Our twin toddlers thrived in the structure and had so much fun working with the coaches. They got to experience all of the equipment and became excited about the sport.”
“Great place for dog walks, picnics, and sunsets! You can see far into the flatirons and the reflection across the lakes are spectacular! Winter is a great time to explore with the colors you can see. The pond scum comes a bit more in the summer but beautiful nonetheless. I've seen people fishing and kayaking there though I'm not sure either are allowed. I love being here for the nature! They have tennis courts and lots of walking trails. This is a great south boulder park that everyone should visit!”

“Body Balance is the best gym in Boulder. Jason has created a community of trainers and clients that is incredibly positive and synergistic. Everyone is encouraging and kind to one another, and the quality of fitness professionals there is the best Boulder has to offer. All of this said without even mentioning how clean and equipped the gym is. They consistently maintain a sanitary environment, and have every piece equipment you'd need for a quality training program. If you want to improve your health and fitness, I highly suggest Body Balance.”

“We spent the day here for a craft fair. We were one of 100 booths for a Christmas arts and crafts event. The place seemed to be clean, the bathrooms were clean and kept up. It seems as if the place was going through a renovation period… I’m not sure ?If I lived in Boulder or close by I would probably go back and use the facilities.”

“Good gym. Bouldering grades seem kind of soft. Having a blast on ropes. Parking is notably bad, but honestly I’ve never had problems finding a spot so far, and I was told there are nearby options in case the lot is full which means you have to walk, but that’s ok.Generally dislike movement due to their business practices, but for the money, they offer a good experience overall between ALL of the gyms.”

“Instead of squeezing in to open gym times at pricey CrossFit boxes to deadlift and squat, have a look at CNE. It's never too crowded, has all the equipment you will ever need, and has 24hr access. Loads of trainers work here too if you need programming or coaching.”
