Fantastic experience: Dropped in while we were setting my son up for CU. The best vibe and group of people. Jeremy and Pat were very nice and helpful. Definitely recommend.

Ralston Creek CrossFit

Thanks for the review Christina! We are glad you had a good time while you were visiting and can't wait to see you the next time you are in town!

Fantastic experience: Hands down the best CrossFit gym I've ever been to. The space is great, coaching incredible and the members/community is even better. They offer different class options so if you're not in to CrossFit you can do their Lift class which is more weight lifting focused and not as CrossFit focused. The coaches really care about you and want to make sure your technique is on point in a friendly way and want you to get better. They'll push you but are also aware if you have any injuries or need to scale anything and are very helpful with suggesting different movements when needed. They put on probably 6-10 events per year outside of the gym which really helps give it a community feel which is what I was looking for. 10/10!!

Ralston Creek CrossFit

Thanks Curtis! We love having you as a part of our community!

Tina Meinhardt 1 year ago

Fantastic experience: Ralston Creek CrossFit has become my new favorite place to spend my time! My fiancé and I joined 1.5 years ago after MANY years of me wanting to join a box but never committing to it; and him saying he “doesn’t like lifting weights, but rather prefers manual labor to build strength.” Well, now we are both a bit obsessed! I am a mountain biker and operate a women’s club and coaching business, which requires a lot of fitness and stamina to constantly be on the bike. I was worried that I would be too sore or tired if I added CrossFit to my daily exercise, which was totally not the case! Instead, I lost fat, gained lean muscle and have become a stronger and more powerful rider! Having dropped in to a few CrossFit gyms recently, I can say proudly that ours is the BEST! The coaches are great and they always spend time reviewing movements, and even offer tips outside of class time if needed. We have loved getting to know the amazing RCCF community and love coming to class! We don’t ever plan to leave and hope to continue making gainz !

Ralston Creek CrossFit

Thank you Tina! We love having you as a part of our community!

Fantastic experience: Honestly, this gym has the best coaching I've ever experienced at a Crossfit gym. Every coach that works here is so knowledgable and extremely good at breaking down the movements to help you warm up properly and ensure you're doing the movements correctly. All the members are friendly, welcoming and very inclusive

Thank you Lauren! Love having you as a part of our community!

Fantastic experience: Amazing coaches, amazing community. Immediately felt welcomed and at home when I first joined the gym, the programming is top tier, and it’s not just CrossFit metcons; anything from Guts and Butts bodybuilding workouts, gymnastics skills classes, and long exposure grit workouts there is something here for anyone at any level of fitness. Couldn’t recommend more.

Ralston Creek CrossFit

Thank you Wyatt! We love what we do, and we love having you as a member!

Scott Keller 2 years ago

Fantastic experience: The saying goes, "..not all boxes are the same." How true it is and I am glad I am part of the MBS II CrossFit community. The focus is on you as an athlete and how to become a more healthier and happier person. Every WOD includes individual attention, coaching and instruction on how to improve your workout and your health - including flexibility, mobility, proper warm-up, nutritional guidance and warm-down/stretching. It is never about beating a clock or fellow CrossFitter, it's about getting better so you can live a long healthy lifestyle. Never have I experienced entire classes enjoy working out together including staying after and warming down/stretching together. At 55 years old, I have never felt better and free of pain - thank you MBS CrossFit II coaches, and I mean all of you!!!!! Scott

Dan Mester 2 years ago

Fantastic experience: I have been a member of MBS CrossFit II in Arvada for the last 6 months and have nothing but good things to say. Whether you are completely new to CrossFit, or a seasoned veteran, the coaching staff will tailor each workout and movement to your needs with safety as the number one concern. The facility is top notch with a wide variety of excellent equipment and also room outside allowing for some fresh air.

Sean Best 2 years ago

Fantastic experience: Wanted to pass along some good news and special thanks to the coaching staff of MBS Crossfit, I receive my blood work results today after 6 months of no prescription or OTC treatments for Reflux or cholesterol levels and I'm in an "ideal range" according to my PCP. This was all a result of just some diet management and good old hard work every week at MBS CrossFit. First time in 13 years I've been completely off of any pill form of health treatment. Thanks to all the MBS family for encouragement and outstanding instruction along the way!

Debbie Swanson 2 years ago

Fantastic experience: I am so impressed with our community at MBS II. From the experienced and well trained coaches who inspire, instruct, and encourage, to the mix of people and ages, MBS II has made my first Crossfit experience most positive. I am also impressed me with the inclusive atmosphere. Being one the older members, the encouragement, the high-fives, and overall positive culture of our MBS Crossfit coaches and members make the class challenging and just plain fun. Well done Crossfit MBS Arvada!!

Alex Ashworth 4 years ago

Fantastic experience: I’m a Doctor of Physical Therapy and I’m here to tell you that RCCF and their coaches are going to keep people OUT of my clinic. They are all knowledgeable about how your body moves and what modifications you might need if something isn’t moving right. The detailed instructions help to meet you where you are in your fitness journey. I came to the gym with some hesitancy about squatting and deadlifting because of a pesky low back issue. I’m now moving better, feeling better, getting stronger and doing it all safely. I can’t tell you how much this gym has changed me in just a few months. I’m so thankful for the team they have in place.

Fantastic experience: RCCF I awesome! All the coaches are incredible; professional, knowledgeable and always willing to work with any questions, issues or change you may need. The space is huge and well equipped and Jeremy (owner) is doing some great things to make it even better - more weights, more usable space, outdoor workout, upgraded equipment etc. There are tons of sessions each day so it's never an issue to find something that works for you. And the crew there is great!! Everyone is crazy welcoming and always pushing each other to be better and get fitter. 100% recommend!!

sally higgins 5 years ago

Fantastic experience: This place is amazing! The owner and coaches are professional, knowledgeable, encouraging, supportive - and fun! They emphasize correct form and are great about assisting with modifications to the workouts as necessary to make sure each person can accomplish their goals. I've had numerous shoulder injuries and have been pleasantly surprised at just how much my mobility and strength have increased in just a few months. As a 58 year old woman, I wasn't sure what the vibe would be like, but the members run the gamut in age and experience and all are super friendly, encouraging and supportive - just like the coaches - making it a great place to be. I'm proud to be part of the RCCF family! Come check it out with a free week - you'll be glad you did!

Ralston Creek CrossFit

Sally, We love having you at RCCF! Your energy is contagious. Keep up the good work. See you in the gym!

makayla keith 5 years ago

Fantastic experience: I don’t think a short paragraph review does justice for this gym! Literally one of the BEST communities I have ever been apart of. Everyone tries to make sure you feel welcome, included in the group, and confident about being there. I have been doing CrossFit for 6 years and recently joined RCCF last year, and let me tell you the coaching is spot on. Each time I go in, the coaches do such a great job breaking down each movement and really emphasizing the importance of good form. The owners, Jeremy and Heather are angels; they are the nicest people who truly care about each individual that walks into the gym. If you are looking for a fabulous gym in the area, I HIGHLY recommend Ralston Creek to everyone of all walks of life!

Thank you Makayla!

Fantastic experience: RCCF is absolutely AMAZING! The coaches are excellent and the environment is so supportive and friendly! I learned more at RCCF in 2 months than I had in 2 years doing Crossfit. I'm so glad my friend got me to switch gyms. Everyone cheers you on and is so supportive of your achievements and goals no matter your fitness level. I have been so inspired and motivated that I can't wait to go to the gym each day! This is the most fun gym EVER but they also get after it and work hard!!

Valerie Limbert 5 years ago

Fantastic experience: RCCF is the best crossfit gym! The community is great! I started here as a member and interned and am now a coach. They had the best coaches to mentor me while I was interning. So glad to call RCCF my home!

Thanks Val!

Val VA 5 years ago

Fantastic experience: There is no better healthy community in Arvada than Ralston Creek CrossFit. The coaches are experienced, knowledgeable, and most of all friendly. It is a family friendly supportive gym. Unlike other CrossFit gyms I have attended, RCCF focuses on safety. All athletes warm up and cool down together led by a coach! The coaches break down EVERY movement before EVERY WOD. They don't simply put a warm up/cool down/WOD on the board and tell you to start. I can't emphasize enough the quality of this gym!!! It's AMAZING!!!

Ralston Creek CrossFit

Thanks Val!

Fantastic experience: Ralston Creek Cross Fit (RCCF) has an incredible coaching staff. I watch younger, fit people continually improving and reaching new goals with the coach’s help. I wasn’t sure what I was getting into when I signed up for a 6 week challenge. I was a bit nervous at working out with others that are physically fit, but everyone that attends are welcoming and encouraging. I joined because my doctor recommended strengthening the muscles around my bad knees and hip to help push off surgery. The coaches adjust my workouts/movements to help me meet this goal while still challenging me. While I still have pain in my hip, my knees rarely bother me anymore. I’m stronger than I’ve ever been. No matter what shape you are in now, RCCF can help you become a better “you”.

Jenna Firstbrook 5 years ago

Fantastic experience: Wow talking about a great community. Ralston Creek Crossfit is a great place to be. Don't let the word Crossfit scare you away. The coaches are very knowledgeable and will teach you to build up your strength and form to make sure you learn it the correct and fun way. The gym also has a Yoga studio called Flow, where you can relax and find your inner self after a great workout. Everybody is very supportive and it will make you feel good being part of this family. Definitely worth to check out.

Fantastic experience: At the Ralston Creek Cross Fit gym it is obvious they care about you! The owners have created a welcoming and positive environment, it is a place I look forward to coming to every day.

Whether you’re a veteran Cross fit athlete or new to the scene you will enjoy your experience at this awesome gym!

Sandy Zapata 5 years ago

Fantastic experience: I love this community! They feel like family and the coaches are very knowledgeable, they know what they are doing. Being injured, the coaches always find a way to adjust the exercises and make you succeed. They motivate you so you do not give up. I have been going constantly since September 2018. I have lost a lot of fat, 3 sizes down, and I can tell my muscles are building up. I never feel weak or unable to lift heavy objects (or kids :-) ). RCCF is very enjoyable because it is a lifestyle... it's not some exercises you do one hour a day, they teach you to live a better life for you and those who surround you. RCCF ROCKS IT!

Jessica Elizabeth 5 years ago

Fantastic experience: RCCF is the best! My husband and I have been members for almost 2 years and absolutely love it. The atmosphere is welcoming whether you're a beginner or advanced athlete. The coaches are fun, knowledgeable, and helpful. Not only are the staff members great, but it truly is a warm and welcoming community of people. I've been through injuries, pregnancy, and postpartum and RCCF has been able to support and accommodate every level of fitness!

Lindsey Westley 5 years ago

Fantastic experience: Ralston Creek CrossFit has welcomed my entire family with open arms. We’ve taken advantage of traditional classes, personal training, teen classes, kids classes and nutrition counseling. You name it we’ve done it at RCCF. The coaches have all been amazing at meeting us where we are at and helping us to reach our goals. What we love most about the RCCF community is being able to fitness as a family while showing our kids that fitness is fun and lifelong. It’s really something special to watch your kids hit new goals and build confidence. We know we owe a lot of that growth to RCCF and the supportive community our kids are surrounded by. We have super hectic schedules but somehow always find time to meet as a family at RCCF - we don’t have to leave our kids at home which is a huge bonus! You will often find our entire family at the gym cheering on each other and encouraging all the other members. You might even spot my husband and son having a little friendly competition. We love the RCCF community and encourage you to take a chance with us!

Micah Roehr 5 years ago

Fantastic experience: After moving to the area and trying out other crossfit gyms, RCCF was the community we knew we wanted to be a part of. The coaching is AMAZING, even helping me modify movements at 9 months pregnant as well as helping me safely return to working out post baby. ‘The Creek’ is super inviting and welcoming, and we’ve made so many lifelong friends. Joining was one of the best decisions we made. DO IT!

Bobbi Kennedy 5 years ago

Fantastic experience: After being out of crossfit for a while due to a bad accident, I was reluctant to return. To say I was self conscious for a gazillion reasons is an understatement. This warm community of all the diverse levels & ages of members and coaches, and their friendly & supportive natures immediately make you feel welcome and proud of your individual accomplishments. They offer many programs to enhance your overall health and lifestyle choices. This in turn encourages you to strive and thrive in your wellness goals.

Fantastic experience: Voy a RCCF desde Otoño 2018 y me encanta el grupo de entrenadores que tienen así como la diversidad de atletas (madres, padres, jóvenes mayores). Te hacen sentir bienvenido desde el principio. Mi opinion sobre Crosfit es que es un ejercicio súper completo y para todos los públicos y RCCF es el sitio perfecto para hacerlo de forma segura y divertida!

David Acosta 5 years ago

Fantastic experience: I am not a fan of gyms, I have never been. I’ve tried a few over the years, working out by myself, getting a personal trainer; it just isn’t my thing. My wife had told me to join RCCF, but you know when you wife tells you something, you do the opposite thing :-) so I did not join. My mantra was: I rather do exercise outside, bike, play tennis, ski. However a good friend of mine “gifted” me a 1month subscription to RCCF, not sure if she was trying to be subtle about something….anyway, so I tried it. And…let me tell you, it is not what I expected. I actually enjoy it! Workouts are different, if you are tired, busy or feel like not want to do the exercise one day, you skip it, no biggie. The next day there would be something different to try. I’ve lost 20lbs in 3 months, being honest not just from going to RCCF, but also eating better (cutting on delicious carbs a lot). But RCCF has helped not just be a slob loosing weight, I feel much better. I am usually pretty energetic person, but since going to RCCF I have even more energy. I sleep better too. I can see results on the bike as well, I feel a lot stronger, being able to do longer rides, more climbs and being faster. Skiing has improved a lot too, stronger legs, stronger core, let’s me not get sloppy on my form and enjoy a full day without getting tired. I haven't played tennis this season, but I hope the fitness allows me to play better too. The crew at RCCF is great, they are all great athletes and in awesome shape, but they are not intimidating at all, everyone is very approachable, Jeremy, Val, Amy, Matt; they want you to do your best regardless of what other people do. There is a certain level of competition to encourage you to always improve yourself, but never too much where you feel bad. My fellow Cross-fitters are all nice, they motivate you, make you want to do one more rep, and come back the next day. RCCF is a great place to get healthier/stronger while having fun. I highly recommend it.

Ralston Creek CrossFit

So glad you are a part of RCCF!

Anna Weyeneth 5 years ago

Fantastic experience: I’d have to say the first thing I’d like to comment on are the Coaches at Ralston Creek CrossFit. I’ve learned and improved from each of their coaching tips in the last 10 months since I joined. This box has always got something extra going on. We just finished a 6 week challenge as a gym included food nutrition, the importance of sleep, giving back to our community, supplements, meditation and self-care. Four Physicians were brought in to talk with us about the importance of self care and nutrition. I’m changed from what I’ve learned the last 6 weeks. And my lifts are better with the help of the coaches. And I’ve got a solid group of people who I want to hang out with outside the gym. I’d say this place helps me win at life. Go Team! I Love this place!

Jill DiGrappa 5 years ago

J. Reid Thomas 5 years ago

Fantastic experience: Ralston Creek Crossfit's coaching, programming and community really separates itself from the other crossfit gyms I've visited. I'm now coming up on completing my 3rd year and couldn't be more thankful for the personal growth, functional fitness and friendships I've built since starting. I was bored spinning my tires with gym workouts. RCCF has been a fun, competitive and challenging way to break free of mundane training and see greater results. Excited to keep at it!

Ralston Creek CrossFit

You the man Reid!

Dell H. Chappell 6 years ago

Fantastic experience: RCCF was such an amazing experience, the trainers are extremely knowledgeable and helpful with all styles of workouts. It was my fiance and my first time doing crossfit and we felt amazing, the trainers even had nutritional tips for after the workout was done. If you are interested in fitness while having a good time go check this place out...

Kate Beyer 6 years ago

Fantastic experience: I’ve been going to RCCF (formerly MBS) for a year now and it’s changed my life. I’m so glad my husband finally pushed me to walk through the door last summer. I still have so far to go with goals I want to achieve for myself , but I make slow and steady progress each week thanks to the amazing coaches and community that RCCF has created. I’ve tried other Crossfit gyms while traveling and they just aren’t the same and it makes me appreciate RCCF so much more when I return. Jeremy and Sam are great coaches and will help out no matter what level you’re at and no matter how hard you THINK the WOD is. The coaches and RCCF members have always made me feel included and welcome from the day I started. The WODs at RCCF are super fun and challenging at the same time. It’s also true what the coaches say - your nutrition is extremely important too! Once I started focusing on what I ate + Crossfit at RCCF, then I started to get stronger! Thanks RCCF!

Jodi King 6 years ago

Fantastic experience: If you are looking for a place to CF this is the best! They work with every level teaching you to be safe, gain strength, and have fun. I was new to crossfit and totally intimidated, but the coaches and the members here made it easy and fun. The support and encouragement from the coaches and the members is like nothing I have experienced. RCCF is not only the best gym but my forever Gym.

Norma Black 6 years ago

Fantastic experience: I first came to MBS as a way to spend time with my son. But before long, I realized I was getting stronger and more confident. For those leery of CrossFit, I encourage you to try MBS. You won't be disappointed. It is the most efficient and effective way to become functionally fit. The coaching staff truly cares for every member and is invested in caring for them through quality training for their Mind Body and Soul.

Shelley Rio 6 years ago

Fantastic experience: MBS Crossfit is the best! I am new to Crossfit and was scared to death, but found the coaches and staff to be so nice and welcoming. The coaches are great at scaling the workouts to your ability and they make sure that you are safe, have fun, and of course get a great workout. I have been to both locations and have found that to be true for both of them. I have been there a few months and have already noticed a big difference in my strength and endurance. Highly recommended!!

Anna Rose Bain 6 years ago

Fantastic experience: I've been doing Crossfit for just over a year and started with RCCF (formerly MBS Crossfit II) last summer. The whole environment is amazing - I love how supportive they are as a gym community, and the fact that they are so family friendly! The coaches are incredibly experienced and have helped me continue doing Crossfit throughout my pregnancy with all the proper modifications. This gym makes me want to keep coming back every single day.

Daniel Goodman 6 years ago

Fantastic experience: I started at RCC when it was MBS and I have loved it since day one. I started out in the "New You" Program and transitioned to the more advanced classes after a couple of months. It has been nearly a year and a half and I haven't even come close to getting bored or disinterested, in all actuality, I look forward to coming here and getting the "bang for the buck" that this Crossfit box offers. I have learned a lot from all of the coaches, staff, and the community of athletes. Everyone has been incredible throughout this journey and I only intend to learn more and become stronger. I would like to thank the RCC staff for making this a safe and FUN place to expel some stress, workout with a great team and make me feel a part of a great community. Couldn't ask for more.

Morgan Minser 6 years ago

Fantastic experience: We tried a lot of crossfit gyms in the area before committing to RCCF, and we're so happy that we did! The staff are what really make this place great. Not only are they super supportive for someone brand new to crossfit, but they make every workout challenging and fun!

Rebeca White 7 years ago

Fantastic experience: MBS CrossFit... totally an awesome place to work out. All the coaches have such great personalities, fun & outgoing. They are serious in helping you to achieve your goals. Just finished a 12 week workout program going for another six. I feel so much stronger than I did 12 weeks ago it's amazing how far I've come in everything we do. Thanks to all of you at MBS CrossFit you're amazing.

Kyle Moschetto 7 years ago

Fantastic experience: When my wife and I moved to Colorado, finding a great CrossFit gym was high on our priority list. MBS is owned by Pat Burke, a multi-time CrossFit Games athlete. MBS II is run by the amazing Heather Young and you will not find a more friendly and caring coach. We've been CrossFitters for over a decade and knew we were looking for a great community of good people and caring coaches. This place is everything you could want in a fitness community. Their beginner programs are inclusive and paced perfectly, the daily classes are challenging and constantly varied, and if you are a fire-breather you will find a great group of competitive athletes. We bought our house to be close to MBS and have never looked back. Try a class here - you will be very glad you did.

Fantastic experience: I love MBS CrossFit! It is such a fun place to work out. The coaches are amazing they help with technique and assist to scale if needed. They are awesome motivators! Not only do they have great coaches, the community altogether are like a big family who support and encourage you to do your best! It's just an awesome place to go for a great workout and to feel better about yourself.

Fantastic experience: MBS Crossfit II is a fantastic gym! The coaches are educated, patient and really focus on safety and form. I was a little nervous to start as I wasn't in good shape, but everyone made me feel welcome and the team is so incredibly supportive. If you have been thinking about crossfit and just haven't taken the plunge, NOW is the time and MBS II is the place.

Fantastic experience: My experience at MBS ll has been nothing short of exceptional; coaches, members, equiptment, and programming included. I have been a member of the MBS family for two years now, and find myself always surprised by the diverse programming. It never gets easier! I appreciate being consistently challenged both with physical attributes and diet, but also by the (family) members of the gym. I have had opportunities over the years to visit crossfit boxes across the country, but truly none compare to my home gym, MBS. What they are offering is not a one sided look in health, but a multi dimensional learning opportunity to overall wellness. In addition to incomparable crossfit programming, I am also able to attend Flow yoga at the conjoined studio, seek out further mobility with a licensed chiropractor, and participate in diet challenges that teach different facets of training. If you are looking for a gym that lends you no friendships and anything short of amazing results, this is not the gym for you. I encourage you to stop by and see what all the fuss is about, I'll be there !

Fantastic experience: I joined MBS almost 2 months ago and it has been GREAT. I came in at a VERY beginner level meaning I was out of shape and new nothing about CrossFit. Their on-boarding program with Coach Heather is amazing...she gets you all the basics and makes sure you are comfortable before transitioning you into the classes. The people have been so welcoming and supportive and it is truly making a difference in my life. I would highly recommend MBS to anyone at ANY fitness level.

Fantastic experience: This is what Crossfit IS! Felt welcomed and like I was a part of their community from the second I walked in the door! The coaching and programming is topnotch! You can tell right away that each coach truly cares about helping everyone become a better crossfit athlete, not just giving them a workout to complete. I feel challenged and pushed in every WOD, but never intimidated. Such a fun community of great athletes! I have personally been to most of the crossfit gyms in Arvada, and MBS is just a level above all the others!

Fantastic experience: Overall I can't be more pleased with MBS CrossFit. I previously tried another CrossFit gym which I thought was good ... but now that experience doesn't even compare. The biggest difference to me is the orientation / on-ramping of new gym members. The first gym I went to was a bit all-in, learn as you go, with just a week of on-ramp classes. MBS on the other hand, provides a full month (3 days a week) of on-ramp classes for newbies. That's a pretty helpful confidence booster if you're new to the sport or not in a gym environment much. And you can transition over to the standard class early if you're ready. Outside of that, all the coaches are incredibly helpful, friendly, and encouraging. Highly recommended.

Fantastic experience: I've been a cross fitter for a few years and have tried a few box's. Plus I travel and hit gyms on the road. MBS is at the top! The coaching is great, the programming is tough and the community is the best. I would highly recommend it if you are looking for a new gym or dropping in while traveling.

Hannah Leeth 7 years ago

Fantastic experience: Just, wow! Joining the CrossFit Arvada community was the best choice I could have made. I feel so welcomed and supported by every member. It's so empowering to be surrounded by a group of people who all want the same thing, and that is to be the best version of themselves possible! The coaches are phenomenal and don't allow you to give up on yourself, they push you through each workout with such motivation. Each coach and member are all so encouraging, and the atmosphere is totally uplifting. They truly represent what CrossFit is all about. I hands down recommend coming in and working yourself with literally the best people around!

Negative experience: I had an appointment at this location for the new you 6 week challenge on Friday the 21st at 12:45 once I arrived at the location no one was there. I drove a very far distance to make it to this appointment was very upset that no one was there never received a call to reschedule or anything.

Fantastic experience: Amazing trainers and atmosphere in every class. Anyone can do this because of all the experienced coaches around and helping and teaching! Great gym!

E Syms 7 years ago

Negative experience: I had an appointment to interview for the new you six week challenge for April 21st at 12:45pm. When I showed up no one was there. Never receive a call back from Heather or anybody. I usually don't do reviews but was very angry I drove a very long distance to make it there.

Kristen Freiboth 7 years ago

Fantastic experience: I am going on my 8th week at MBS. So motivational and the coaches are amazing. Really teach you the right and wrong way to do things. I feel great and love going. Not what you would usually here me saying about a workout!

Aimee Charlton 7 years ago

Fantastic experience: I have always struggled with my weight. Add that to bad knees and asthma and you have a recipe for feeling constant failure when it comes to fitness and working out. That has changed at MBS Crossfit II. I began the New You (6-week) Challenge 10 weeks ago. After two weeks I was hooked. Day one I could not do a single squat below parallel, I couldn't do a lunge without gripping a bar for support and I couldn't do a single full sit up. 10 weeks later and I just completed the Crossfit Open accomplishing more than I ever though I could. I have accomplished 150 ft of walking lunges carrying 40 lbs in a single workout. I can do 50 sit ups in a workout. and just this morning I hit a personal record of 195 lbs on a back squat. And yes, I was below parallel. :-) Though my weight loss will still continue to be a journey, my body is getting stronger every day and I am losing inches. Most importantly, I have an emotional support system that constantly encourages me to be the best I can be including diet and life in general while always celebrating wins and encouraging me when I am challenged. In fact, Heather (co-owner) even checked in with me recently remembering that I had set a goal at the beginning to put myself first when it comes to health and wellness. Something I have long struggled with. I thought it was amazing that not only did she remember what that personal goal was, but she also took the time to reach out to me and see how I was doing towards it. I have to say, with everyone's help at MBS Crossfit, I am well on my way towards that goal. I haven't pulled off a pull up yet. But I know I will and I know I'll have many there to cheer me on when I do.

Fantastic experience: My first experience of MBS was on Memorial Day of 2017. I was invited to participate in one of CrossFit’s most anticipated workouts, Murph. At first step into the gym, I was welcomed into the family and then quickly joined the MBS community as a member after that day. I have had experience with two CrossFit gyms other than MBS. Both of these gyms’ focus was on packing weight and being “stronger” individuals. As a result, I injured my shoulder during a power clean. I was very discouraged and disappointed that I was pressured into packing an unreasonable amount of weight onto the bar without proper technique. My time at MBS was filled with excellent coaching and community support. MBS is not about hitting the “RX” or “getting jacked”. MBS CrossFit is about quality coaching and instruction on how to move efficiently and safely. With these factors into play, I was able to touch up my technique and grow in strength. Within three months, my backsquat PR grew by 40lbs and my clean PR grew by 60lbs. What I learned from the MBS community is that our bodies are able to push, pull, jump, run, lift, throw, and squat in any possible combination. I learned that quality is superior to quantity. I learned that muscle-ups aren’t hard with the assistance of False Grip technology. I learned that fitness is easy to achieve with the right approach. I am grateful to the coaching staff for pushing me to be a highly functional individual. I feel much stronger and a more holistic athlete after a short time. If you’re looking for a place to help you get to the CrossFit Games, a place to help you be a better athlete, a place to help you recover from an injury, a place to help you be healthier, a place to help you push your twins in the stroller, or a place to enhance your community experience, MBS is the place for you. MBS is a place of community, safety, nutrition, and strength. We are made to move, go to MBS, and get MOVING! Thank you, Jeremy, Rich, Heather, and Kyle for everything you have done for me and the community! Forever, Mind. Body. Soul. Daniel B.

Fantastic experience: This place is AMAZE-BALLS! I've been going for the last 13 weeks, and I can't believe the progress I've made. The coaches here are top notch and scale everything to meet your individual goals/needs. I participated in the 6 weeks challenge, and just never stopped going. If you're looking for a laid-back, no judgement place to get your sweat on, this should be the first place on your list!

Marissa Lee 8 years ago

Fantastic experience: I cannot say enough positive things about MBS. I whole heartedly believe they deserve 10 stars!! Honestly, I was pretty intimidated to try Crossfit mostly worrying that I wouldn't fit in and I wouldn't be able to do the workouts. Well, I was wrong and now I regret not starting sooner! MBS made me feel at home from day 1. There was no awkward newbie transition. I joined a class my first day and never looked back! Reasons to try Crossfit at MBS-II 1. Coaches - Knowledgable, friendly, supportive, motivating. I have worked mostly with Rich, Jeremy, and Amanda. All top notch! They take the extra time and go the extra mile. I have learned a lot from each of them. And, if you have little ones, the kids coaches and class is awesome too! 2. FUN!!! - Should workout out be fun?? YES!!! This is the main reason I love this place. Is it challenging? Do I get an awesome, sweat dripping work out? YES and YES, but its fun! Camaraderie, supportiveness, cheering, high fives!! It's great to be surrounded by others with a common goal. 3. Progress - I've noticed an improvement in my mobility and endurance. And, best of all my strength. Having a coach that provides the correct instruction, helps to correct my form, and pushes me to keep going is why I NEEDED Crossfit in my life. I was going nowhere on my own. 4. Scalability - Can't do a pull up? No problem. Push up? No Problem. Don't feel you are strong enough? Doesn't matter. Everything can be scaled to your level. All fitness levels can find a home here. Stop driving by and try it out!!

Fantastic experience: I have been member at MBS CrossFit in Arvada for a year now and I’m amazed at how far I’ve come. The coaching staff is amazing! They are incredibly knowledgeable and help you work toward your goals. I love how they really work on form and the progressions working up to skills. The MBS community is wonderful! Everyone is so friendly and helpful. This box is the best!

Jen N 8 years ago

Fantastic experience: MBS II Arvada has been an amazing experience and addition to my fitness journey! Fitness is a partnership and MBS nails it-- collaborative, encouraging, inspiring and scalable. It's simple: you work on being the best version of you. I can do a little more today than what I could do yesterday...and that, combined with the awesome group of people surrounding you, is what keeps me coming back. Kudos to this humble box and it's contribution to the wellness movement, in Mind Body & Soul.

Andrew Taylor 8 years ago

Fantastic experience: From the moment I walked in I knew that this gym was the place for me! This gym is very community based and does lots of events together. The coaches are very professional, led by the 6 times games athlete Patrick Burke. Safety is key here and the coaches ensure that everyone within the class is performing the movements correctly and safely. Wonderful space and lots of parking. Great equipment and very clean! Whether you are just dropping in or looking for a new "home" MBS II is a great choice!

Nate R 8 years ago

Fantastic experience: My wife and I have been to other CrossFit gyms and have never felt like we belonged. At MBS CrossFit II, everyone greets you, encourages you during workouts and pushes you to do your very best. The coaching is absolutely amazing. Whether you have been doing CrossFit for a long time or just beginning you are always treated like a true athlete.

Erin Wulforst 8 years ago

Fantastic experience: I've been doing CrossFit for over 3 years and have been to different CF boxes during that time. By far, MBS stands out above all the others. The coaching staff is top notch; you can tell how passionate they are and they truly want EVERYONE to succeed- not just the elite athletes. Every wod focuses on proper technique and no matter what the workout is, it is scalable for anyone. MBS has several highly qualified coaches that rotate in the weekly schedule. Because of that, you'll never experience that coach burnout like other CF gyms that have the same person coaching every class day after day. Our community is the best-- you feel welcomed, included and supported. I look forward to coming to the gym and for me the hardest decision each day isn't "should I do CF today?" it's "which class should I go to?" !! Look no further --- MBS is the place to be!!

Joseph Cassara 8 years ago

Fantastic experience: Had a great experience here. I've driven past this place on way home for years and wish I stopped in sooner....Did 1 month on-ramp and then signed up for membership. The coaches and members are simply great. People are motivated to get a great work out and supportive with an understanding everyone has different levels of fitness; we're all there to improve and challenge ourselves. Nice camaraderie . Can't say enough about the coaches, they really make the experience. I've mostly worked with Heather, Rich, Jeremy and Amanda. All knowledgeable and incredibly helpful. All like to have fun. All like to see you challenge yourself to get to your fitness goals. Don't keep driving by...

jamie johnson 8 years ago

Fantastic experience: If you're looking for a safe and fun place to Crossfit then MBS is where you want to be! The coaches are great, very friendly and eager to share the knowledge to keep you safe while working out. They are great motivators! The programming will push you but is safe and effective, it just makes sense. All the workouts are offered at three different levels so even a beginner can participate. People here are nice to each other and encourage you to do and be your best. I've been a member for a little over a month and have never been disappointed!

Jaime Kostelnik 8 years ago

Fantastic experience: I can't say enough good things about MBS - I was extremely skeptical of crossfit after a previous experience, but I am so glad that I decided to give MBS a chance. The coaches, community, and atmosphere are awesome. Coaches spend time instructing and encouraging athletes of EVERY ability. If you have been intimidated to try crossfit or have had a not so great experience somewhere else give MBS a chance to change your mind. Extensive knee injuries/surgeries left me feeling pretty down and out physically, but after only 6 months of my MBS membership I feel like a totally different person. If you want to look and feel stronger, happier, and healthier give it a chance!

Scott Chiesa 8 years ago

Fantastic experience: MBS Crossfit II has a great community of like minded people who just want to be better at life. You can finish first or you can finish last but you'll have people cheering you on 'til the end! It's an excellent group setting that still feels like you have your own personal trainer. Sure, you can go and join a globo-gym and end up sitting on your ass after a few visits of walking on a treadmill whilst reading a Good Housekeeping magazine -OR- you can join up at MBS and actually SEE results while having fun working out. It's not just exercise - it's bettering yourself whether it's through nutrition to working past your mental humps to just plain watching your clothes fit better. Just give it a shot for a week - you won't be disappointed!!

cathy dachel 8 years ago

Fantastic experience: Always greeted with a hello and a high five for your work, MBS creates an environment where everyone feels at home. The coaches are fun and motivating and not only lead but instruct on proper form. I recently took the summer boot camp and had the best time. Where else would you look forward to going knowing you would be doing burpees and sled pulls? Thank you for such an awesome experience!

Andrew Yeh 8 years ago

Fantastic experience: MBS Crossfit did a great job with introducing me to Crossfit. I had never been to a session before and the opportunity came up where I could do the on-ramp course. I enjoy every minute of it, and it was an awesome experience!

Brittany Tangsrud 8 years ago

Fantastic experience: Great gym with an amazing community. The coaches are highly skilled and make sure you're being safe as you workout. Since joining this gym last August, I've had amazing results!
