CrossFit® CM2: Opinions
Fantastic experience: I've recently moved here and love the place already. The coaches are amazing and the members so welcoming. I've learnt so much already that I thought would take months.
Fantastic experience: Fantastic owners, and superb coaches, age or ability never a problem, programmes bespoke to both i highly recommend a visit
Fantastic experience: Great atmosphere at this gym, all the members are so friendly and I was made very welcome. Coaching is of a very high standard. Thank you Coach Cath!
Fantastic experience: 8 months ago, I was anxious about having to find a new gym and CrossFit never sounded like something I could ever be part of. I am not in the typical demographic and I was worried about not being strong enough, fit enough or even just “looking right”. How wrong was I? I have found the most supportive, encouraging, and coaching from all of the brilliant coaches at CrossFit. I love the fundamental aspects of CrossFit, the continuously changing programme, the scaling options and the range of activities and goals. I can honestly say there are no egos at CM2, what everyone has in common is enthusiasm for fitness and a friendly and supportive attitude, it’s a brilliant community to be a part of. Any regrets? Only that I didn’t start my CrossFit journey sooner!
Fantastic experience: When I first joined CrossFit CM2, I hadn’t worked out in a long time. However, the experience has been amazing – our coaches are friendly, supportive, they got great expertise and the community they’ve built around CrossFit is exceptional. The coaching team is excellent, and the classes are carefully planned to support each member. It’s all about personal growth and competing with yourself. Now, after three months, I feel guilty when I miss a day! I 100% recommend CrossFit CM2 to anyone looking for a welcoming environment, amazing coaching, and a supportive community to help us to reach our goals.
Fantastic experience: Amazing place to train and great community! Highly recommend for anyone including complete beginners! Fantastic supportive and highly experienced coaches.
Fantastic experience: WHAT A PLACE!! It’s basically my second home - the members are great, the coaches are super supportive the atmosphere is like no other.
Fantastic experience: Top Cross fit Gym, great Coaches and great atmosphere!
Fantastic experience: Amazing CrossFit box full of great people. They cater for all people and levels with expert coaches who really know their stuff. The community around CM2 is incredible!
Fantastic experience: Great CrossFit gym! Very supportive and a great community- The coaches are all wonderful and push you to help reach your goals. I’ve been coming here for about 7 months now and started as a complete beginner with very little strength or fitness. From day one I was encouraged and shown how to build on my strength through various classes and am pleased with the progress I’m making. I was nervous about starting to begin with and worried that I’d be rubbish compared to others but quickly realised that none of that mattered; there are members here of all abilities here and everyone is friendly and happy to help show you the way. This gym quickly becomes addictive as you keep making progress and setting PBs! I’m constantly realising that I can do things I thought I couldn’t and that wouldn’t happen without all of the encouragement and support of the coaches here. Can’t recommend CrossFit CM2 enough :)
Fantastic experience: Great gym, great people, great vibes Doesn’t matter your age or fitness level, the coaches will scale all workouts and motivate you to achieve your best. Always learning new exercises and techniques keeps it fresh! Would recommend
Fantastic experience: The community is what makes the CM2 so special! Coaches have real passion for sport and focus is always on personal development of the box members, every class has got the feel of personal PT session!
Fantastic experience: Brilliant CrossFit box. Top owners, coaches, facilities, programming and atmosphere. Best in the area by far. Chris Ellis also has the best funky footwear
Fantastic experience: Amazing CrossFit gym with a brilliant community. The coaches really take the time with everyone at all levels to make improvements from beginners to elites. Loving it here
Fantastic experience: CrossFit CM2 is amazing! I’ve been going here for nearly a year and I love it. The coaches are amazing and so encouraging and I’m challenged every time I’m there!
Fantastic experience: I joined CrossFit CM2 after having a difficult experience at another CrossFit Box. I have been with them for just over 6 months now and I couldn’t recommend this place enough. Not only have I learnt and developed so much from the quality of coaching, I have been accepted, supported and never ever been made to feel like an outcast. There are no machos here, if you aren’t experienced then you will learn, everybody has to start from the beginning. There are no mirrors, there are no expectations, if you want to join an atmosphere that feels like a family, build confidence, attend socials, be included, not experience judgement, be part of friendly teams when you feel ready, get fit, change your life, mind and body .. this is the gym to join!!
Fantastic experience: I joined CM2 July 23 as a complete beginner to CrossFit & I am now addicted to this place - the coaches all want you to be your best and are always happy to scale and explain anything! The ethos of this gym is workout hard, but also have fun & be a part of a community. All the members are so nice - no egos. ⭐️⭐️⭐️⭐️⭐️
Fantastic experience: I've been coming to CM2 for just over 2 years and it's the most consistent I've ever been with strength and fitness. I put that down to how social the gym is, alongside the drive to want to learn new skills, which CM2 encourages. They offer a variety of skill based classes, which often cost extra at other gyms, which is awesome to see!
Fantastic experience: I’ve been a member at CM2 for about 5 months now and have had the best time! Started a complete beginner and a little bit nervous but the coaches and rest of the members made me feel so welcome. Workouts are fun and challenging and the coaches are great. Can’t recommend enough!
Fantastic experience: CrossFit CM2 has transformed how I view fitness. With scalable workouts suitable for beginners like me, it keeps sessions engaging and fatigue-free, unlike traditional gym routines. Now, aiming for goals like achieving a handstand push-up feels within reach. CM2 isn't just a gym; it's a doorway to a life filled with movement, sport, and adventure.
Fantastic experience: I've just started my third month. I've been made to feel so welcome, the classes are amazing and I leave feeling great every time. I've had several years out so my workouts are scaled. Everything is possible and there is so much to aim for. If you're goal oriented and love challenging yourself and seeing how far you can take yourself this is the place to be! There are no contracts because the experience and community feeling brings you back. That alone is testament to how good it feels to be part of this place!
Fantastic experience: I joined Crossfit CM2 a few weeks ago, and its been a fantastic experience! The community in the gym is brilliant, full of supportive and friendly people, and the coaches are all incredibly knowledgable and helpful. Im very new to Crossfit, but have been made to feel super welcome, and am already hooked! Would recommend to anyone!
Fantastic experience: I’ve been to 10+ CrossFit boxes & functional gyms across 3 continents & I have to say… CM2 is hands-down the BEST! Amazing, kind trainers; challenging yet progressive programmes; range of classes - it’s clear everything they do is about making your customer experience better & better! Shout out to owners and all the trainers - you have been fantastic!!
Fantastic experience: This is a great gym, if you are into CrossFit or not, Just go check it out. I am in my mid forties and I can honestly say I am in the best shape of my life. Coaches/Members are always super friendly. Just give it a go, you wont regret it.
Fantastic experience: Honestly, CrossFit is not something I ever thought I'd be into with kids and work seemingly taking over my life, and my fitness taking a hit. My husband suggested I give it a try and I wouldn't be without it now. The sense of achievement, cameraderie and atmosphere is fantastic. Thank you CM2 Team!
Fantastic experience: Totally awesome box!!! I love dropping in when I am back in essex for a partner workout on a Saturday. The classes are buzzing and the atmosphere is the best!!
Fantastic experience: Been going for nearly 6 months now and I can honestly say I won't ever be signing up to a regular gym again. I encourage everyone to get into Crossfit . The coaches at CM2 are all brilliant and always on hand to help with techinique and answer any questions and all the members are friendly and welcoming. Good social events throughout the year. Workouts are scaled to your ability so don't be put off thinking it looks too difficult.
Fantastic experience: I was quite nervous before starting at CrossFit as I thought I needed to be mega fit and strong to join, despite already having a reasonable level of fitness. I have been here for a few months now and am surprised at just how much I enjoy it. Everyone is very welcoming and the coaches are so supportive and help those who haven't been lifting weights for long to scale accordingly. It is great to be able to just turn up and know you will be able to get a great workout without even having to think about it. I definitely recommend CrossFit CM2!
Thanks for the review Lizzie! You are killing it, keep up the good work!!

Fantastic experience: Great gym, very friendly and knowledgeable trainers. Highly recomended
Fantastic experience: Brilliant CrossFit gym in Chelmsford! A must visit!
Fantastic experience: I've been attending this CrossFit gym for 4 years. The coaching is excellent and the community is second to none. Friendly, challenging, fun. Not only do they offer standard CrossFit exercise classes they offer occasional outdoor events, social events, competition events. Plus you get to meet inspirational people from all backgrounds and ages. It's great!
Fantastic experience: I’ve been a member for over 10 years. Prior to that I was a fairly regular gym goer and mountain biker (still am) but I never got the results in terms of strength, skill and general fitness that I have achieved at CrossFit CM2. As a bonus though, the members are great and I’ve made some superb friends there. My only warning - be careful it doesn’t take over your life!! I introduced my wife (back when she was fit but not into weights or pull ups) and now she’s a coach and shows me up with her gymnastic awesomeness! ❤️
Fantastic experience: The BEST! I could go on and on forever about why you should trial at CM2, just book up and see for yourself. You will be greeted by the best coaches and the most amazing people who will support you, help you and give you the push you might need during that workout! I am a mum of a 2 and this place is for ALL abilities! GET INVOLVED IN SOMETHING YOU WILL NOT REGRET! :-D
Fantastic experience: Cannot recommend highly enough! Not only is it a great gym with fab classes, varied but progressive programming and superb coaches they also have a level of care for their members like none other in the industry! A real breath of fresh air in a saturated market. Will not be going anywhere else any time soon!! Stop searching for other gyms and book a free trial here!!
Fantastic experience: I’ve been a member at CM2 for a year and a half now and absolutely love it. The coaches are brilliant, the atmosphere is relaxed and it really is for everyone, no matter your ability. There’s lots of different classes to choose from and you’ll never struggle to get a spot. Would recommend to anybody who’s thinking about trying it!
Fantastic experience: Absolutely love CM2! Been a member for a couple of months now and I can’t get enough! Such a friendly place to train with brilliant coaches and programming alike - no matter your ability, the sessions cater for all and the vibes are always banging! ✌❤️
Fantastic experience: I recently just started at CrossFit CM2 after having recently moved to Chelmsford. Rob the head coach messaged me personally welcoming me to the area and made me feel really welcome to the gym answering any questions. On my first session I was made to feel really welcome everyone introduced themselves and the workout program looks great, stuff for all people of all abilities. The facilities are awesome and the staff/ coaches are really friendly. The head coach Rob is extremely knowledgeable and you can see he has a real passion for what he does and this comes across in the class If you are looking to give CrossFit a go - what a good place to give it a try!
Fantastic experience: Great coaches and a real focus on form and improving!
Fantastic experience: Friendly atmosphere, great place.
Fantastic experience: It's awesome!
Fantastic experience: I've been a member here for about 6 months now, and out of all the gyms I have tried in the past, I can honestly say this one I have felt most at home in. The coaches at Crossfit CM2 are knowledgeable, friendly and patient, spending time with each person to ensure technique and form is correct. They also are always happy to offer scaled variations of workouts for those who are struggling, or more challenging options for the more advanced. Most of all though, they offer a lot of support and encouragement that often wills me to push myself further than I ever would do so personally. One of the best things about CM2 is just how friendly it is. There are no egos, nobody laughing at or judging you, and nobody asking you when you will be finished with a piece of equipment! Over the past 6 months, everybody I have met here has been friendly and a pleasure to workout with. There is always a familiar face to greet you, and have a chat with before or after class, and new members are always made to feel welcome. Because of all this, it really does feel like you are part of a community rather than just a member of a gym.
Fantastic experience: Was a bit daunted at the thought of joining a Crossfit Gym, as let's face it, they have bad reputations for being cliquey and valuing speed and reps over form and function. Happy to admit I was totally wrong in the case of CM2. Can't say I enjoyed myself at the tester session (hard work!) but all of the coaches at cm2 are brilliant and spend a lot of time helping everyone to ensure good form; with rehabilitating injuries, and obviously encourage you to reach goals. It is a really nice friendly community at the gym, and there is always a face to say hi to whatever time of the day I manage to get in the gym. They also have great week on week programming and offer Olympic lifting, strength and gymnastics sessions as well as the normal WODs. If you're thinking about joining or coming down for a session, just take the plunge! It's great!
Fantastic experience: Primarily a class based format, specialising in functional fitness - Olympic lifting, gymnastic strength and various formats for metabolic conditioning. The coaching and programming is first class, couple that with the friendly group format, it never get's boring and there are constantly new goals to work to. Suitable for all abilities, you'll be tested appropriately whether you are a novice or seasoned athlete. A fantastic place to learn new things and get in the best shape of your life! I'm loving it!
Fantastic experience: CM2 is like my second home, the members and coaches are friendly and approachable and always there to help and encourage you. They welcome all new faces and immediately make you feel at home and not at like the 'newby'. The coaches really care about your training goals, they build on the basics so you're not rushing into movements too advanced for your level. There's a cross section of athletes at CM2 so no matter your ability you never feel left out and your personal achievements will be a big deal to everyone! If you want to work hard and have fun, CM2 is the place to go!
