I've been a member of Roots since moving to Boulder in 2012. In my biased opinion (and isn't that what Yelp is all about?), Roots is the best CrossFit gym in all of Boulder ... and the country, far as I've seen - and I've dropped into my fair share. Let me explain: * The size of the gym is spacious, not cramped, and always clean and organized. Total win. * There's a mindful flow to class structure with a group warm-up and WOD intro that is guided - it's never a free-for-all. And the class waits to break their sh*t down until everyone is finished WODing. * The coaches are the best, most skilled IMO. They care about form and foundational movements and technique. They keep class sizes small so you get the attention you need, whether you want to admit it or not, to get better and, more importantly, move safely. * They have four dedicated Oly platforms, where is where I now spend the majority of my time. I love that. I got my own space to work on my Oly lifts or pull out a rack to back/front squat, without having to fight for space, barbells, or plates. * They have ample Open Shop time that I utilize for shizzle. No other gym in/around town is going to let you treat their shop like your own personal gym, but Roots does with near-daily Open Shop times that let you come in and do your own thing, catch up on a WOD you might've missed, or work on technique and gymnastics. * There's always a coach onsite. If you need a spot, some advice, or general pep talk, you don't have to look far to get the support you need as an athlete. I love that. Sometimes, you may even get advice from a coach without asking - that's how much they care. Okay, here comes the WARNING: If you join Roots - or even try it for a few days and classes, be ready to FEEL SPOILED. To feel like no other gym will ever meet your expectations, because that's exactly what will happen. Roots is the best, worth every cent, and very accomodating for all athletes of all ages (they have a kids program and a seniors program), as well as community-minded and welcoming. To be honest, when I moved to Boulder without knowing ANYONE, I got through that first awkward couple of years (you know, trying to meet friends and trying to feel at home) because of Roots. I started in their Women's Only program and made fast friends with the ladies, before I self-graduated myself into the standard track after doing the 2014 Open. If you're a member of Roots, I think you can agree with me - you feel like you're part of something special, something important, something worth preserving at all costs. It's not the cult-mindset (ha, like that even exists in CrossFit); it's the Roots Family outlook. When you're in, you're in. read more

My wife and I have participated in CrossFit since 2007. We have visited boxes all across the country and paid drop in fees or been invited to join a workout at no cost. This week at CrossFit roots after participating in a multi-day gymnastics seminar coached by Shane my wife was invited by her classmates to participate in the daily wod. When she attempted to walk into the group coach Shane asked her "what are you doing". My wife made her wishes known and was coolly informed she is not a member of that box and may not participate. Even when another athlete offered immediately to invite my wife as her guest coach Shane remained adamant that joining the wod was for some reason against the rules. This is a disappointing experience to have at such a well-established box. CrossFit Roots is known to be the home of several well-known CrossFit athletes, good coaching and unfortunately also a somewhat callous management. If you are looking to join a box in Boulder I cannot recommend CrossFit roots. read more

Always one to give the latest fitness fads a whirl I thought I would check out what everyone I know in Boulder seemed to be talking about: Crossfit. Turns out it's not really a fad at all, but more like an addiction. It's one hour a day, as many times a week as you can handle of hard core sweat it out work. An emphasis on total body strength includes a lot more weight work than I'm used to (but have totally grown to love) as well as lots of quick work to get your heart pumping. The instructors are awesome, and the workout changes daily (my fave part). Plus I'm closer than I have ever been to doing a pull up (psyched!) Check it out and I doubt you will look back! read more

I have been to many gyms around the country and CrossFit Roots has, hands down, the best CrossFit coaching you can find. The staff is committed to furthering their craft and becoming the best they can be, as evidenced by the number of Level 3 and Level 4 CrossFit Trainers and the gym's internal professional development. Roots has 5 out of the 75 Level 3's and 1 out of the 6 Level 4's in the state of Colorado. The coaches also are committed to developing and including athletes of all levels , so whether you are on a competitive level, are new to athletics, are a teen, a senior, or anything in between, you will be supported and welcomed at Roots. (Disclosure: I am related to the owners.) read more

I trained at CF Roots while in Boulder for work, and the experience was fantastic. I would I could make this my everyday gym! The staff was accommodating, and the members were very welcoming. If you need a place to sweat while in town, this is it! read more

Only three reviews? Well here is number four. This is one of the finest Crossfit experiences I've been around. I was lucky that this was my first gym thanks to some local friends that suggested it. It's now my home court but I also am lucky to see many other gyms in the US and Canada. This place is special. Not just the facility (large and well equipped) not just the other members (welcoming and chill but still competitive), not just the location (central) .... But the coaching. The coaching here is world class, personal, and every one of them is top notch. Nicole (owner) is on Crossfit staff so the gym stays true to programming from HQ, but always with safety in mind. Nicole and the team take personal interest in your progress and it works. Visiting Crossfitters look no further and those wanting to start make this your first stop in Boulder. read more

After moving to Boulder recently I made it a personal goal to get back in shape. Ten years of desk-work had really taken its toll...even with fairly regular weight-lifting workouts. My body tends to respond really well to more dynamic workouts so the Crossfit model felt like a good fit for me. Before I started my career in high-tech I worked as a personal trainer and NSCA certified strength and conditioning coach. In that time I worked with top athletes (NBA,, Division 1, Olympic) and coaches in very elite training programs. Given my past experience in the field I came into this program expecting to be underwhelmed by the coaching. I'm pleased to say I was totally wrong. The owners at Roots have made a point to invest in hiring really solid talent. The coaches here are exceptional. They're educated, smart, and very well trained. They're also very attentive (you won't get away with cheating on your workout here... believe me I try all the time!). It's a bit of tough love mixed with a fun, friendly, and communal workout atmosphere. My only criticism of Crossfit in general is that the group programming is sort of a blunt instrument for getting in shape. If you have very sport-specific needs or need a workout tailored to certain physical limitations, then you may need to consider working with the training staff on more of a 1:1 basis. If you're like me and just want to cut fat off and look and feel better, then the group programming is a great way to get the job done. I've lost 10lbs in the first month and feel like I'm building a solid foundation to really accelerate towards my personal fitness goals! read more

Excellent gym. Fantastic instructors! The owners are attentive, kind, and really love what they do and it shows. Felt apart of the community right away. The attention to detail and correct form is honorable. I would highly recommend this gym to anyone and I do! If you want to see what it's all about attend one of the free introduction classes. You will be glad you did! read more

CrossFit Roots is a great gym with a strong community, focused on fitness and giving back. Apart from talented coaches and a welcoming environment for athletes of all abilities they also find ways to contribute to causes beyond CrossFit - most recently sponsoring disabled athletes who are part of Achilles Boulder run club at this years Bolder Boulder 10k. Good business run by great people. read more

I am obsessed with CrossFit!!!! I'm making my way through all the gyms in town & this is a great place to train. The coaches rock!!!

Definitely the best CrossFit gym you will find in Boulder! Great space with fantastic views of the Flatirons, friendly, caring - coaching staff. Amazing website with interesting content, events above and beyond classes such as happy hours, fund raisers, educational talks - this is not just a gym but an amazing community. If you are in town this is a don't miss opportunity! read more

Been going here for four years now, top notch box. It's interesting to do drop-ins at other boxes when traveling, I'm always grateful to come back to roots. Top ranked coaches and trainers in the US, if not globally. Great athletes to workout with. Great location. Great box. Highly recommended. read more

When I started at Crossfit Roots six months ago, I had no idea how much of an impact it would have on my life. The coaching staff is very knowledgeable, supportive, and professional. They have been so helpful as I am learning more about Crossfit and functional fitness. I never thought I would be capable of doing half the movements but quickly learned with proper instruction that I am. Seriously, a wonderful facility with an awesome community of athletes and coaches! read more

Without a doubt THE BOX IN BOULDER!!! When you go to a workout at ROOTS you get to the root of exercise, the root of the movement, the root of the workout, the root of proper form, the root of a great coaching experience, the root of friendship, the root of support and the root of community. It really is all about finding your base at Roots. The coaches are phenomenal. They want you there, 100% present engaged and focused on the WOD but they also want you there for the next WOD and the next and the WOD 10 years from now. They are committed to helping you with form, functionality, movement standards and most importantly keeping you safe and healthy so you can keep crossfitting for years. Crossfit has a reputation to go hard and don't stop but not at Roots, you can go as hard as you want - if you are safe! The coaches are potently skilled at watching you and offering corrections - and aghast!! - will tell you take down weight, even use a PVC pipe if the weight is to much. That is why I keep coming back - I trust my coaches inherently and completely. And I love that they keep wanting to better themselves.They all keep testing levels up! No stopping them. The community is truly one of a kind - being a Root is something special. You make friendships that last - maybe because you see each other in such stages of disrepair that it makes friendships easy. All athletes hold each other in the highest respect. They always cheer each other on and help pick up after the WOD. And Roots has lots of social events that allow you to see each other not in workout gear. So many times I've dragged myself to a WOD against my will because I know when I get there I'll see friendly supportive faces. The facility is exactly what a box should be. All the right equipment for any WOD you need or to explore any crossfit exercise during open shop. No frills - a shower and bathrooms, changing rooms and cubbies to store clothes. It is just perfect for what a true Root needs. Nothing fancy as our focus is on the workout. Classes!!! oh hell yeah - Roots offers teen classes, over 55 classes, endurance classes, oly classes, track WODs, - really any thing that you crave, Roots will meet and surpass your desires. Really - you have got to give Roots a try. I mean where else can you do GHD sit ups while looking at the world famous Flatirons. read more

When I moved to Boulder, I went to Roots before I even bought a bed on recommendation on a two people I met in CA. Best decision ever. The community is wonderful. We have a great time and I'm stronger than ever. Roots is one main reason we may never leave Boulder. read more

Obsessed!! This place has the best instructors and athletes in Boulder!! If you are looking for a community of good people this is your place!! read more

CrossFit Roots is hands down the best place to work out in Boulder. The level of coaching is beyond anything I've ever experienced. Each coach is eager to help their athletes reach their goals and the community has changed my life. I love this place and everyone at Roots! read more

This is by far the best Crossfit box in Colorado. The level of coaching is far superior than any other boxes I have ever been too. Most of the coaches of Level 3 and 4 certified and have the unique ability to pull out the best from all their athletes. The warmups are thorough and coach led to prepare for the wod! The community is welcoming and embraces every visitor and new member to the fullest. All level of Athletes go to classes and push each other whether you are new or experienced. Nicole and Eric constantly hold events to foster the community environment. Crossfit Roots is more than just a crossfit box it is a community! read more
