Fantastic experience: Best CrossFit gym and coaches around! As a 5 year CrossFitter, I've been to a fair number of gyms and Boulder CF is the top. I'm also an orthopedic specialist and PT, and the coaches are excellent about cueing for good form and monitoring your activity to ensure success and decrease injury risk. Can't recommend the community and coaches at Boulder CF enough!

Daniel Larremore 8 months ago

Fantastic experience: Really nice culture at this gym. And I love how the coaches bring what you need, whether it's teaching you new movements and safety by breaking things down into steps, giving you corrections to keep improving form, or just shouting your name super loud when you're pushing yourself. I also appreciate the wide range of athletes — made it a lot easier to dive in and get started at 40+.

Craig Jenquin 8 months ago

Fantastic experience: The people were the best part. Great instruction, clean facilities

Emily Ruebelman 9 months ago

Fantastic experience: If you’re visiting like me, just moved to the area, or looking for a new fitness challenge, look no more!! Boulder CrossFit is your top choice. The coaching staff are so welcoming: I was dropping in for a week while traveling, yet I felt like a member of the gym. The facility was clean, the community friendly, and the workouts rockin! Boulder CrossFit I hope to see you soon!

Boulder CrossFit

Thank you so much for this review, Emily! We loved having you in town and we can’t wait to see you the next time you are in Boulder!

Andrew Gomez 9 months ago

Fantastic experience: I've been a member at BCF for about a year now and my biggest regret is not starting earlier. I was pretty intimidated by CrossFit but BCF owner Monique, all the coaches, and every other member have been so incredibly welcoming. Huge emphasis on form and safety at this gym and I've made major gains in my athleticism across the board. If you're looking for an amazing CrossFit experience I can't recommend BCF enough

Boulder CrossFit

Thank you so much Andrew! You have had major gains and we love having you as a part of our Boulder CrossFit family!

Fantastic experience: BCF has exceeded expectations for the 3 years (and counting) that I've been a member! The coaches are attentive and communicative, prioritizing safety for all movements -- always reviewing technique during warmup and providing feedback during workouts. The gym is extremely newcomer-friendly and has a positive, supportive, and socially active community (and is also home to some of the most fit people I've ever met).

Slava Fedorchuk 1 year ago

Fantastic experience: Update 08/08/24: I am still a member and gym is getting better. Space was reorganized a little once again. More CrossFit and classes and clinics are available. Go BCF! Update 10/31/22: I am still a member and gym is getting better. Space was reorganized to accommodate new equipment. More classes are available due to growing athletes numbers :) Go BCF! I am one of the many members of the Boulder CrossFit. I am with this gym since 2018. It is a good place to get fit and find friends. Coaching staff is knowledgeable, friendly, very supportive and attentive. BCF has early morning, noon and evening classes. Gym / class capacity is limited. Walk-ins are allowed, but spot in class is not guaranteed. It is better to call upfront. Usually new participants have a free introductory week. Despite common misperceptions this program is for practically everybody. You come here not because you are great athlete (well, we have them among us!) but rather to get fit and maybe become an athlete. Groups of coworkers and/or friends, families are quite common here. Coaches will always adjust exercises for your abilities and will make sure you stay safe avoiding injuries. Come, try, join! Update on 06/2024: additional classes on Saturday, Sunday and during the week.

Fantastic experience: Hands down the absolute best gym I've had the pleasure of working out in! The owner Monique cultivates a welcoming atmosphere of warmth and positivity. Boulder CrossFit is the perfect gym for athletes of all shapes, sizes, and fitness levels and provides an extraordinary amount of expertise and support whether you are an absolute beginner or seasoned CrossFit veteran. I couldn't imagine working out anywhere else!

Boulder CrossFit

Thank you so much, Seth! We appreciate you, the energy you bring everyday, and this review so much!

Tim Morrissey 1 year ago

Fantastic experience: I have had a great experience with Boulder Crossfit for the past two years. They turned me into a gym person. Highly recommend this gym, especially for someone who might be thinking they are not fit for Crossfit (either physically or mentally). They make it work for everyone and its worth it.

Fantastic experience: If you’re looking for a great CrossFit gym with awesome workouts and a fantastic community, look no further! Since joining Boulder CrossFit my health has improved in so many ways. 10/10 recommend!

Hunter Wills 1 year ago

Fantastic experience: I first moved to Colorado Nov 2022 and was looking for a bar when I found Boulder CrossFit! Sounds absurd but they are all so inviting and welcoming!! They will push you to your limits but not without regard to safety. They are a great group of people who push each other to do better both in the gym and in life. They have outside people come in and teach classes about specific skills and they do workouts at places like red rocks and competitions at other gyms!! Get in there and get your sweat on!

Fantastic experience: I have been to many CF gyms over the last decade. This one is the best. They pack a lot into an hour class, so it's a super efficient use of time. Everyone is so cool and genuinely welcoming. I regret not joining sooner.

Madeline Cohen 4 years ago

Fantastic experience: Boulder CrossFit is amazing. Fun, challenging workouts always with meticulous attention to form and athlete ability to ensure that each of us is progressing steadily without getting injured.The coaches are fun, knowledgeable, supportive, and the community is great. I have a serious visual impairment, and the coaches have been amazing at making sure I can follow what is happening and navigate the gym without ever making me feel disabled. This place and its people are the best.

Waleska Estrada 4 years ago

Fantastic experience: Boulder Crossfit has changed my life for the better, for the last few years I have been looking to unite myself in a gym but I never knew that Crossfit was for me. Ever since the first day that I joined Boulder Crossfit, I felt welcomed and helped me believe in myself. 10 months have passed and the only thing I regret is not having started sooner. Boulder Crossfit has become my home, my happy place, and a place where I can be myself and not be judged and Boulder Crossfit has brought the best out of me. I am super grateful for my coaches for the time and patience they have had for me. I love you guys!!! Crossfit is for everyone. If you keep your mind open you could discover a new passion. But Boulder Crossfit is not just a gym, it's family❤

Fernando Villanea 4 years ago

Fantastic experience: When I moved to Boulder my top priority was finding a Crossfit box that fit two criteria, first I wanted coaches who paid close attention to technique (in particular for new movements) and second I wanted a strong community feeling. Boulder Crossfit stood out immediately to me as the best box in town, the owner and coaches are both friendly and honest, they pay close attention to the needs of their members, and have built a strong community, promoting team workouts and social activities such as outdoor workouts and events. As a 6-year Crossfit participant, I really appreciate that the coaches will still pay attention to details and help me improve, but pay even more attention to new members, focusing on their safety. The equipment is also top-notch, and there's a good selection of non-crossfit gear for accessory workouts during open gym. I cannot recommend this gym enough, 11/10.

Fantastic experience: I’ve been a member of several CrossFit gyms and this is by far my favorite. The coaches are amazing. They really know how to break down complex moves in order to scale and grow. The camaraderie among members is welcoming and fun. The class schedule is really convenient with plenty of options that work with my schedule. I highly recommend Boulder CrossFit!

Fantastic experience: best CrossFit gym in town and best CrossFit gym I've worked out at. Amazing coaches and members make for a fantastic community. Everyone supports each other in their goals, whether you're just starting or been doing CrossFit for years you'll feel at home here. The age and cultural diversity of members makes for an awesome inclusive space for everyone. Also, plenty of space to workout without getting in other people's way.

Fantastic experience: Zach and the team of coaches at Boulder Crossfit are some of the kindest and most supportive people I've met in Boulder. I always heard about how competitive and ruthless the crossfit environment was but when I came to the gym it was totally different. The atmosphere was full of positive energy and everyone pushing each other to be better. Highly recommend.

Jeff Briley 5 years ago

Fantastic experience: Dropped in this afternoon on my way up to Breckenridge and have to say this is a great Crossfit box. From the coaching to the members I felt very welcomed from the time I arrived till I left. I’ve dropped in to boxes all over the states and many in Colorado and have to say this is at the top of my list for places I’ve been. The coaching is great, the facility is nice and all the members I encountered were very friendly. Will for sure be back!!

Fantastic experience: Worked out this week at Boulder CrossFit. Love the huge space and high ceilings. The facility was clean and very organized. Greatly appreciate the friendly hospitality and workout.

Christopher Meyer 6 years ago

Fantastic experience: I was out of any workout routine for nearly 2 years and needed to do something about it. My colleague got us a trial week at Boulder CrossFit and I've been going consistently for about a year now and I can't emphasize how the staff make the difference. I definitely would have dropped off had it not been for Jen and Gary who actually cared that I reached my goals. I'm definitely stronger now than I've been at any point in my past!

Brandi Klaus 7 years ago

Fantastic experience: Love this place! Super clean facility! Everyone I encountered was friendly and encouraging, instructors and students. I strongly dislike working out, but they actually make it fun! I took the 30 minute conditioning class with instructors Dylan, and Park; both were awesome! I highly recommend this gym.

Ash B. 7 years ago

Fantastic experience: We dropped in on our road trip from Philadelphia and Gary and CFB were so welcoming. I sent an email and he called back with in minutes. We had an awesome workout and afterwards he gave us tips on what to see in Boulder. Would definitely drop in again! Highly recommended this place. Thanks Gary!

Patrick McDougle 7 years ago

Fantastic experience: Friendly people, friendly staff. Working out is hard, but the staff make the workout fit you instead of making you fit the workout.

Emma Smith 7 years ago

Fantastic experience: I've tried a few different CrossFit gyms and none of them have been as welcoming and awesome as Boulder CrossFit! The owner, Gary, is so incredibly thoughtful and helpful, he's really worked with us to make sure we're setting realistic goals for ourselves and achieving them. All of the coaches are knowledgeable and approachable. If you like an atmosphere where you're constantly being yelled at drill-sergeant-style, then this place is not for you. But if you're looking for a constructive community that will gently push you to be your best self, you must try Boulder CrossFit!

Amber Wright 8 years ago

Fantastic experience: Boulder CrossFit changed my life! For the first time, I made fitness a priority in my life and it was due to the encouragement and camaraderie of this community. Gary genuinely cares about his members and their success. I for one hated working out in "public" for the fear of being judged. This is absolutely not allowed in this gym. We support each other, we cheer each other on and we ALL celebrate the gains. My transformation would not have happened without the love and support of every person at Boulder Crossfit! I cannot thank them enough!!!!

Sarah Morris 8 years ago

Fantastic experience: GREAT gym! I initially had about 6 months of crossfit under my belt at a different box before I was looking for a change. I tested out every gym in Boulder and knew immediately I had found a home at Boulder Crossfit. The location, coaches, programming, schedule, and class sizes all played a factor in the decision, but it fit the bill for everything! I would highly recommend to anyone regardless of fitness, experience, age, etc.

Alanna Parker 8 years ago

Fantastic experience: BEST GYM IN BOULDER! I have been going to Boulder CrossFit for six months now. It's one of the best decisions I have ever made. I had not done CrossFit before but the environment that has been created at the gym is amazing. This gym is for everyone at all different fitness levels. Both coaches and other members are all extremely supportive. You will not regret going to Boulder Crossfit! VERY HIGHLY RECOMMENDED!

Brittany Free 8 years ago

Fantastic experience: Best. Gym. In. Boulder. We searched for a while to find a local gym in Boulder. Too crowded, too flashy, too judgy... we ran across them all until we found the perfect fit at Boulder CrossFit. This is such a supportive gym where all ages and body types are welcome. It doesn't matter where you are in your fitness journey, you can scale each workout to fit your needs. Highly recommend!

Fantastic experience: Amazing, supportive & knowledgable coaches. Boulder Crossfit is a welcoming community that encourages athletes to have fun & reach their goals. I've been going for almost a year and have lost weight, run at a faster pace, and am so much stronger. It's awesome to see what my personal records were when I started and what I'm at now.

Tom Curren 10 years ago

Fantastic experience: Early one Monday morning two years ago, I made a quick tour of all six Crossfit Gyms in Boulder. I chose Boulder Crosssfit because of the open, airy gym and what seemed to be an exceptional friendly and open community. After two years, I have not been disappointed. There are bigger programs in town, but I love the size of this program. You get a friendly "Hi" from everyone when you enter the gym. The level of support matchs the intensity of the workouts. Everyone does things they formerly thought were impossible. Check it out yourself. Tom C.
