Five stars isn't a high enough ranking for MBS Crossfit--I cannot say enough good things about this gym. I've been a member there since July 2008 and joining was easily the best health decision I've ever made. What really makes MBS stand out from other gyms is the fantastic leadership provided by Pat and Janelle, the owners and head coaches. They provide training for everyone, whether you're just getting started or working towards a personal record strength goal. They'll creatively scale workouts to everyone's fitness levels or to work around an injury. They make sure you're doing movements properly to prevent new injuries (which was a problem I experienced a lot before joining MBS). And they are great at motivating and pushing you to your limits during workouts. On top of the amazing, high-intensity workouts which alone are well worth the membership price, they also offer a slew of extra information like olympic weightlifting training, stretching and martial arts classes, and nutrion seminars that are available to all members. They organize groups within the gym to help us set and meet goals as well as challenges with other CrossFit gyms in the area to help build camaraderie between the people you're working out with. I love MBS because they offer a total approach to fitness, and take the time and personal attention to help you reach your weight loss, strength gain, or speed increase goals. I'm completely hooked and can't imagine working out anywhere else. read more

I LOVE THIS GYM! First - the location. It's in a huge airplane hanger large enough to accommodate the large class offering of WOD, CF1, Oly, and Cardio-flex. The view is spectacular - open the hangar door and there is a gorgeous view of the front range, and it is not uncommon to see F-18s taking off on the runway just outside the hangar. Second, the schedule - as I listed there are a number of classes to choose from. There is something for everyone and plenty of classes to meet the needs of pretty much anyone. Third, the perks! Unlimited membership gets you four free yoga classes, they have a massage therapist and Rossiter practioner on-site (at additional cost) to help manage mobility, address nagging aches and pains and help with injury prevention. And last, but MOST IMPORTANT, the staff!!! The coaches are top notch! Pat Burke is not only a world class athlete, he is dedicated to coaching his athletes (and every single person at MBS is his athlete regardless of athletic abilities or condition) to be their best. His programming is written so that it can be modified to accommodate beginner to serious competitor and his coaches make sure it is properly modified to prevent injury. He holds his coaches to high standards and they coach every movement and monitor form of every athlete. I can't say enough good things about MBS. I love this place and the people there. There is something for everyone, they welcome and serve all levels. Go check it out! read more

This isn't your fly by night Crossfit gym. The owners and coaches are ligit. They make sure you know how to properly do movements before increasing weight. Having been hurt at a gym before, that was very important to me. There are also many high level athletes that work out in this gym. These are not the meatheads that carry around a gallon of water and look at themselves in the mirror. These other high level athletes are working out next to you, encouraging you, motivating you, and often watching your form. Several times a year, there are nutrition challenges which are very helpful to keep your diet on track. As a lifelong endurance athlete, I thought I was eating healthy. That got turned on its head when I did my first diet challenge here. Since then, I've ditched the cholesterol meds (at my doctors recommendation). The facility is cool too. Lots of room to workout, plenty of equipment for each member. And classes almost all day. There are other gyms that are closer to my house, but MBS would have to change an awful lot before I'd change gyms. read more

MBS is the BEST!!! My husband and I started doing Crossfit because I was a person who got burned out on every workout routine I started. My husband thought the variation Crossfit provided would prevent me from getting bored with yet another workout routine. He was right!!! It was perfect for an extreme athlete as my husband was and someone who just likes working out as I do. Not only are the workouts great at MBS, the community Janelle and Pat have created is extraordinary. After my husband's spinal cord injury in January 2014 MBS and the members went above and beyond to help our family in any way possible. Now that my husband has gained more function back, Pat makes time in his busy schedule to modify workouts and works one on one with him for a couple hours twice a week. If you are looking to try Crossfit or looking for a new gym, MBS is the place for you!! read more

MBS Crossfit has knowledgeable, helpful, friendly, and fun coaches who focus on teaching you all the lifts, movements, and techniques. They help you on form, mobility, and even nutrition. The athletes are fun, strong, witty, smart, and encouraging people who are always willing to cheer you on in a WOD or lend a listening ear. Located in a renovated airplane hangar, the box itself has amazing views of the Flatirons and it's always treat to see fighter jets taking off and landing at the Jefferson County Airport. Unlike other Crossfit gyms, the philosophy at MBS is to be the best YOU can be. I do not stress out or worry about scaling a WOD or not being as good or as fast at a movement as another athlete at the gym. Instead, I am encouraged to better myself and celebrate my successes no matter how small. MBS is a community that I am proud to be a part of! read more

This place is awesome! Stop reading this review and go to MBS! All the coaches are great, the people are great, and the location is great too. When I first started my fitness level was about a 1 out of 10, and everyone has always been patient and helpful, always taking the time to make sure I fully understand a movement. I was a little intimidated when I first started but quickly got over that once I realized the environment was quite friendly and accepting. The onboarding process was very smooth too which made joining that much easier. All in all, I can't recommend this place enough. There's a reason it's ranked the #1 Crossfit gym in Denver. read more

Totally new to Crossfit (at the ripe old age of 39) I recently started working out at MBS and am so grateful for the AMAZING coaches who have helped me so much on my journey. They have a great CF1 program to teach newbies the basics and then they set you on your way. Every WOD is full all types of athletes, with the coaches still offering great instruction. However, the atmosphere here never feels intimidating, but rather, is totally inspiring and encouraging. No matter how hard a particular workout is, I guarantee you will always have fun working out with so many great people. Like the other reviewers state, this gym truly offers it ALL. read more

I love being at MBS CrossFit in Arvada. Since joining a month ago I have learned a lot of new exercises and Olympic lifts I've never done in my 30 years of lifting. I've lost several pounds but more importantly, I'm getting stronger. The thing I'm most excited about is the improvement in my recovery time between sets or 'work". I feel better than I have felt in years and I truly value the quality of instruction I receive from the instructors. Each of the instructors I've had have a different style but they all take the time I need to help me improve in my form. I highly recommend MBS CrossFit!!! Chris Tolar Boulder, CO read more

I love MBS!! I checked out 4 gyms in the area before I chose MBS and I have not regretted the decision. There is plenty of space and equipment, so you never feel cramped during a workout. The coaches are knowledgeable and actually take the time to help you improve form and technique. The programming is diverse and there is even a partnership with core power for yoga. The 5:15am crew is consistent...there is tons of support and we share a lot of laughs. And you really can't beat the location especially when we open the hangar door and the sunrise illuminates the flatirons! read more

Started midsummer and haven't regretted it for a second. Incredible coaching, high attention to detail and an environment that's not going to push you to the point of injury for the sake of pushing big weight. You'll start out in a crossfit light class that is way more comprehensive than most gyms and be able to show proficiency in each major movement before moving on. Fellow crossfitters range from high school on up and the demographic should allow anyone to feel comfortable. If you're looking for a new box, or a box for the first time, don't overlook these guys. read more

While it seems there is now a Cross Fit gym on every corner, Cross Fit gyms are not the same! I have now tried four of them in Colorado searching for my Cross Fit home. MBS is that home. MBS is hands down the best Cross Fit gym that I have been too. The level and quality of the coaches far exceeds others. At MBS you train with the Elite of Cross Fit Trainers and Athletes. The community at MBS is more like a family where everyone is welcome and encouraged. If you are new to Cross Fit or an elite Cross Fit athlete, MBS is the place for you. read more

I am a member at the Arvada location and I am new to CrossFit. I started my CrossFit experience at a low level of fitness and MBS and their members has made me feel so welcome to their community. Being new the coaches have taken the time to show me the correct way to to do the movements and I have over the last couple months seen great progress in losing weight and gaining endurance to do the workout. I am so happy that I have the opportunity to work with trainers of this caliber! I would highly recommend MBS to all fitness levels. read more

MBS is the best crossfit gym you will ever experience. They have mastered not only the community of crossfit but also the sense of family. The coaches are all amazing. The facility has breathtaking views. The owners, Pat and Janelle are extremely passionate about everyone's individual goals. Whether it's to compete, to lose unwanted pounds, or to have a healthier lifestyle. If you looking to check out crossfit, look no further! MBS is waiting for you! ;) read more

Can't say enough good things about MBS CrossFit, both Broomfield and Arvada. The coaches are experienced and patient in coaching all age levels - kiddos, teens, adults, and masters - as well as all skill levels, total newbies to the elite athlete. The community makes even the most brutal WODs fun, and the facilities are great. BTW, Broomfield's location has magnificent views. I enthusiastically recommend and am grateful for MBS CrossFit. read more

Great Coaches Friendly members World class facility If you're looking for a little competition, or just want to move and get a good workout, MBS is the place for you. I've worked out here through a competitive season, pregnant & postpartum, and through injury, and MBS has been able to meet all my needs through all different seasons of training with great coaching, support, and awesome resources (chiro/rehab in house)! Highly recommended read more

I have been attending MBS for about two years, and have found it to be a challenging and enjoyable community of instructors and participants. When you leave the box after a workout, you are an improved version of yourself. The instructors are attentive and always stress form and safety over all else. The setting - an airplane hangar on the airport tarmac, with a killer view - adds to the experience. read more

I had a great time in the New You Challenge class at the Broomfield location. Jessi especially was so knowledgeable about cross fit as well as nutrition and went the extra mile to educate us. I was so nervous about taking this class but Jessi's kind and patient demeanor as well as challenging me to work harder. I am so grateful to MBS Crossfit and especially Jessi! read more

MBS CrossFit is fantastic! Top notch coaches and lots of great energy. It's in an airplane hangar and the hangar door opens to the tarmac. If you've ever thought of trying crossfit... you should definitely stop by and check out MBS CrossFit. Even if you haven't really considered crossfit, you should take a look at MBS. Such a great community of folks. read more

Great gym for the experienced & newbies alike! They certainly made me feel welcome when I first stared crossfit. The location is breathtaking. The coaches are seasoned and very knowledgeable about physiology & form (versus just pushing intensity I've seen other places). The people are friendly & encouraging. Check it out, you won't be disappointed. read more
