I've been a member of Roots since moving to Boulder in 2012. In my biased opinion (and isn't that…read morewhat 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.

My wife and I have participated in CrossFit since 2007. We have visited boxes all across the…read morecountry 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.

Park and his staff are knowledgeable and caring, and they carefully cultivate a gym culture where everyone feels like part of the same team. I'd never done any olympic lifting before, and I initially thought it was really intimidating, but they are so great about teaching safe and proper form, and not pressuring you to throw more weight on the bar than you are ready for. In any workout they are able to give you options for modifying a movement if you have an injury, or maybe just aren't advanced enough to do the "Rx" version (me). I can't recommend them highly enough!

Upon arrival we were greeted by the friendly and knowledgeable GM Candice. Her passion for the brand and offerings was palpable. She herself was a member for over a year before she took the position. Together we reviewed the cool gear, lotions, supplements, amenities as well as all the different studies (cycling, rowers, yoga, etc.). Classes refresh about once a month ensuring you don't get bored. Class sizes are limited to 3 to ensure you have enough space to safely and enjoyable enjoy your workout. Before class started we were acquainted with the infrared sauna our class would air in (on tv built into the wall). We learned how to turn off the lights, increase the volume and most importantly adjust the heat to suit our preferences (heat was set to 125 which we lowered down to about 105). Our yoga mats as well as foam roller and towels were all nicely set up for us. The class itself was ok. With the tv so high up on the wall it was a little challenging to keep an eye on the instructor without craning our necks. While we felt like we had a decent workout (each tv aired class features different people displaying different levels of difficultly) we really missed hearing music and the fun it provides - tho we were told we could bring our own in via phone or little speaker. Overall this is a super clean place with friendly staff and great membership options. Since you can come in anytime (you get special access via your phone once you become a member) it's super convenient. There's also the added fun of challenges (there were cute handmade goodie bags for past participants at the front - showing the care Candice has for her members). Definitely check this place out if you are looking for a new gym with lots of flexibility and many class options.

There's a reason every person here wrote a 5 star review…read more I came to EDX on the recommendation of two friends to talk to Angelo about individual training. I was coming off a knee injury, had a handful of other aches and pains, and felt like my training (which I had been doing consistently for years), had started to plateau. Working with Angelo has been a game changer, and the depth of his fitness and coaching knowledge is absurd. Simply put, I've made measurable, significant gains in every area of my fitness. While I don't work directly with the other coaches or attend the classes (I use the open gym for the individual training plan Angelo writes for me) everyone on staff is friendly, helpful, and most importantly incredibly knowledgeable. There's no attitude here, just the expectation that you'll show up and work hard. Additionally - I've had multiple sessions with Liliana at EDX Bodyworks (the attached sports therapy clinic) - and she's a wizard, it's a great resource to have on hand for when tweaks and injuries pop up. I've been a member of probably 6 or 7 gyms, this is the best one yet, my membership will end when Angelo and Liliana decide to retire. No matter your fitness level, if you're serious about getting in shape do yourself a favor and give the EDX community a shot.
