Guerrilla Fitness CrossFit Montclair

Fantastic experience: Great Coaches, Great Atmosphere....Love this place!!!

Fantastic experience: Awesome community and super helpful coaches. One of the best gyms I've ever been to.

Fantastic experience: Who needs a gym membership? After all, you could run, do sit ups, pushups and squats on your own time, with your favorite music, at home, for free. But we all know it's hard to get (and stay!) motivated, making results hard to come by. Every Guerrilla Coach is certified, engaged, involved and invested in your health, safety, growth and individual success. They are trained, accredited professionals; they are cool; they are funny; they are smart; they are strong, understanding and helpful; and, they are special. Both Coaches and Members keep you accountable and most importantly, inspired. Many regularly comment that the hour spent at the gym is the happiest part of their day; and, it’s true. Nobody can make you go to the gym, but come to ours and be truly embraced by a community that shares “core” values and takes pride in being an integral part of a supportive, all-inclusive family. We love getting dirty in our meticulously clean, well-equipped and surprisingly spacious space. Guerrilla is a gym with programming and people like no other. Safety, technique and prudent, incremental gains are all part of the philosophy that keep you healthy, strong, flexible and on a path to improvement. Try it - you'll be greeted with a "Hi!" and leave with a "High 5!"

Fantastic experience: Love this place. Fantastic coaches and programming, huge and well-maintained facility, great community, active and involved ownership -- what more can you ask for?

Fantastic experience: Amazing coaches and team atmosphere.

Fantastic experience: Joining Guerrilla fitness has been life changing: The workouts are challenging but fun which is motivating. The coaches emphasize proper form so Ive grown stronger without injuries. The community is supportive so I feel at home. I’m grateful to be a member.

Fantastic experience: When you walk into Guerrilla CrossFit, there’s a certain feeling in the room. There is so many different people in different stages of life. Some come to get fit, some come to de stress. For me, I come to prove to myself that no matter if I’m a beginner or more advanced, I can do this. Guerrilla has been helping me with life’s ups and downs, both personal goals and achievements. The coaches and staff are wonderful to work with. They help and advise me on how to approach my goals and conquer my fears. It’s more than just a class, it’s more than just a workout. When I’m here, it’s home, it’s my second family. Stronger together. Thank you Guerrilla Fitness. Always the best! Jessica Perez Member since 2020

Fantastic experience: A place I like to call a second home. The coaches are incredible, friendly, and very knowledgeable. I am someone who enjoys being pushed to my absolute limit, and the coaches can see the potential within every single person. Whether beginner or advanced their constant motivation, support, and attention to athletes forms and performance is what makes this place a one of a kind. The community at Guerilla Fitness is very supportive, welcoming, and just all around great people.I have been at Guerilla for about 2 years now and my growth and performance as an athlete has exceeded anything I could have ever imagined for myself. This is all thanks to the amazing coaches and the incredible community that helps me get better each and everyday. I personally as an athlete, love good healthy competition as it shows me which areas I can improve in and this community never fails to put my strength and athleticism to the test! I love this place and highly recommend trying out CrossFit at Guerilla Fitness no matter what level of fitness you may currently be in, I can guarantee you the coaches and community will help you reach your goals in the most encouraging and enjoyable way possible!

Fantastic experience: Great box and an awesome gym with solid programming based on my 1 year plus of experience. Real sense of community and suitable for all age groups and fitness levels. Gregg the owner and one of the coaches is an awesome human being all around!

Fantastic experience: This gym has become my second home. I didn’t know whether CrossFit was for me, but this gym is very safe and has a very friendly atmosphere. It is super obvious that ALL are welcome which was important to me. No matter where you are in your fitness journey or where you are in life, this is the place for you. Give it a try and see for yourself!

Fantastic experience: Love Guerilla! The coaches are amazing. My kids also go to train during their sports offseason! It’s a great place for the whole family!

Fantastic experience: All of the coaches are very professional and knowledgable. The environment is very welcoming and its always a fun time. The workouts are always intense but great! I always look forward to going to the gym here at Guerrilla Fitness.

Fantastic experience: I so love it here and highly recommend this place! If you’re looking for a supportive environment to be challenged as you work towards your fitness goals, this is it. Although the classes are in a group format, you’ll get one to one coaching to ensure you’re doing the exercises properly. The coaches focus heavily on your form when you first join so that you have all the basics down pat and they really help you get stronger.

Fantastic experience: I'm so happy I found Guerrilla. I recently moved to the area and was looking for a Crossfit gym with a strong sense of community, and no ego or judgment -- and I found it here. The trainers are all really knowledgeable and work with you to improve form and maximize your ability, and I've found both the trainers and other members really supportive and friendly. All experience levels and body types are welcomed into this small family.

Fantastic experience: Love my community and coaches and GFCF Montclair.

Fantastic experience: Amazing gym, gorgeous facility, awesome and very involved and honest owner, great staff, great community. Socially distanced and safe. This gym has kept me sane throughout this pandemic. Such a supportive and upbeat environment that makes me grin from ear to ear leaving every day. They push you but are also so understanding of any limitations and very helpful with modifying the workout to your ability! Can’t say enough good things. Go check it out.

Fantastic experience: Took a trial class. Awesome! Aaron is a great coach!

Fantastic experience: Super friendly and helpful coaches! Good gym with good people!

Fantastic experience: Amazing gym. I come for the great fitness program and the people, but I stay for the music ;)

Fantastic experience: This is CrossFit at it's best. Excellent coaching. Excellent programming.

Fantastic experience: Always have a great experience. Staff are super friendly! The bartenders are the absolutely best. Love their lemon drops and food!

Fantastic experience: Amazing owner, staff and community. Spotless and following all safety guidelines during this pandemic!

Fantastic experience: I’ve been here for over three years now. Hands down the best physical fitness experience in terms of results and community. I’m healthier and physically stronger now (as a Black woman of a certain age) than I was in my 20s. Can’t wait to see what the next 3+ years bring!

Fantastic experience: Guerilla Fitness is a great CrossFit Gym! Greg and his team of coaches do a wonderful job of creating a friendly and safe environment for all the members. Each class gives me a great challenge and gets me ready for my day. All the coaches are particular in watching me and other members make sure we complete movements with correct positioning and monitoring our exertion. I feel very fortunate to have found such a great place where I can feel like an athlete and perform well even though I've never felt athletic my whole life. I look forward to my workouts there and watching myself surpass what I thought I could do a few weeks earlier. If you are looking for a Cross Fit Gym, I highly recommend coming here!

Fantastic experience: Guerrilla Fitness is truly a fantastic place to become a better version of yourself. The head coach Ayo gives amazing individual attention and is a top notch teacher and an even better person. Highly recommend!

Fantastic experience: I've been a part of the Guerrilla family since October 2008 and there's no turning back. For some, CF might not be their cup of tea, but my cup runneth over and then some! Guerrilla Fitness is THE place to not only get in shape but to push your limits / compete against yourself and maybe the guy or gal next to you. The programming is amazing ( I really wonder how they do it) and the coaches are top notch!

Fantastic experience: Never thought I would do crossfit. 4 years later still a member here. Great coaching, great atmosphere. Highly recommended.

Fantastic experience: I've been a part of the Guerrilla family since November 2008 and it has an awesome community. Guerrilla Fitness has great coaches and the programming is challenging.

Fantastic experience: I’ve been going for over 10 years now and it has just become part of my daily routine. The programming keeps it new and challenging and I trust the coaches as they always focus on form and function first. Overall, excellent gym and community

Fantastic experience: Life Changer. I am grateful for our gym and all of the awesome people in it. Especially Ayo—he is the greatest coach and mentor and has helped me learn and grow in ways I didn’t think possible! I have been a member for about four years, joining guerrilla was one of the best decisions I have made!

Fantastic experience: This gym has quality coaches that are committed to good form and take feedback on their playlists. The classes have always had great energy (big ups to the early morning crew) and a diverse welcoming membership.

Fantastic experience: I love all my coaches Ayo and April along with everything else about this gym. It is amazing.

Fantastic experience: After 18 months, I am so pleased with my experiences at Guerrilla. It is more than just going to the gym, the Guerrilla team have helped me achieve so many of the goals I had set for myself and achieve other milestones I never planned on. The best part is that after 18 months, I don't get bored or feel I have to change up a routine. The Guerrilla team are always looking for new ways to challenge us.

Fantastic experience: Awesome gym! Great coaches and people.

Fantastic experience: This place is more than a gym...it is a family. I have been a part of this gym for just over 2 years and I love it. Every skill level is welcome here. The coaches make every effort to get to know you and encourage you on your fitness journey. There is no need to feel intimidated by the workouts-- you can always scale them down. (Believe me..I know). If you want to meet new friends and family, and challenge yourself with workouts..you should definitely check this place out.

Fantastic experience: I joined Guerrilla almost one year ago at the suggestion of my friend. I wanted to add weight lifting to my exercise routine but found lifting at a regular gym on my own was boring and I didn’t know what I was doing. My friend said I would love Montclair Guerrilla. She is a longtime CrossFitter at another gym who knew of Montclair because it had a reputation for being the best. I was hesitant to do CrossFit because I wasn’t sure I could do it....I had no idea what a snatch or clean was or what AMRAP or EMOM could possibly mean. But I decided to give it a try because I wanted to learn and grow, I wanted to get stronger and the workouts looked awesome, especially with the inclusion of gymnastics moves. From the first day I walked into Guerrilla, I loved it. I loved how the gym was set-up and all the equipment available, I loved the atmosphere - the coaches are awesome, form is the most important thing to them, and they encourage me to believe in myself and my abilities. The workouts are different every single day, so there is no way to get bored at Guerrilla. There is always another level to work towards. The coaches create such a great supportive environment that all of us in class follow their lead and are supportive of each other. Together we are better! There is no end in sight for the goals I can achieve at Guerrilla and my personal growth along the journey.

Fantastic experience: As a gym, Guerrilla Fitness serves in an exceptional capacity; it checks all the boxes off: great environment, phenomenal coaching and programming, welcoming to people from ALL walks of life and varying levels of fitness, incredible energy brought day in, and day out. They make it an outstanding experience for everybody. But, to end it there would be a great disservice, as Guerrilla Fitness is so much more than a gym to SO many, including myself. Over 9 years, it has become family to me. The passion, and care, and personal touch that their team puts out on a daily basis to make sure each member receives the very best experience is nothing short of remarkable. No matter where you come from, I encourage you to give them a shot! You will not be sorry!

Fantastic experience: I’ve been a member for 10 years, and it keeps getting better every day! Superior coaching, superior programming, and an outstanding community. All CrossFit gyms are not built the same, I’m proud to belong to the best. We are Guerrilla Fitness, we are #BetterTogether.

Fantastic experience: If you like to challenge yourself and be motivated by others, then this is the place for you. I have been a member for 6+ years, far longer than at any other gym I've ever attended. At traditional gyms, I had a hard time pushing through the motions of doing the same exercises week by week and would eventually stop going due to disinterest. At Guerrilla Fitness, I religiously go five days per week and my day does not feel the same without it. I am capable of doing exercises and lifting weights that I didn't think were possible before. The coaching is second to none, everyone knows one another, and everyone pushes each other to be better by the time you walk out than you were when you walked in. I can't imagine myself at any other gym.

Fantastic experience: Best gym in the area! The coaches are second to none, so knowledgeable and so encouraging. I’ve been through many stages with Guerrilla as my home gym; working out here post knee surgery, while pregnant, postpartum, AND while training for the Brazilian jiu jitsu IBJJF Masters World Championship. You cannot get that quality from just anywhere. Not only are they of the highest quality, they’re also just really nice people.

Fantastic experience: A great gym. I've been a member for over four years and I can't speak highly enough of the head trainer Ayo Falae. He has tailored a work out program for me that has enabled me to maintain the active lifestyle I've always led into my 60's.

Fantastic experience: This place is life changing! The coaches, the members, the facility!!! Everyone needs to join Guerrilla! It’s worth every single penny! It’s my favorite place to be, my home away from home The coaches are so supportive and so friendly, they truly want you to be better. The owner Gregg, he’s wonderful! Such a positive community that I’m so proud to be apart of!

Fantastic experience: Coaches are friendly, knowledgeable and offer personal attention and the members are welcoming and encouraging. Head coach Ayo is extremely knowledgeable and detail oriented. He provides programming that is effective and challenging with enough variety that has members looking forward to coming to each class. Ayo provides a safe, fun environment while ensuring that each client’s best interests and goals remain the priority. Following his program you will definitely progress and see the results you hope for.

Fantastic experience: Guerrilla Fitness has been my good to me this past year and a half. Not only have I learn so much from my coaches and peers, I learned a lot about myself and capabilities. Spirit week , was one of my favorite community event(s) . It was a great week where all the members got together as a community to do fun activities , such as bowling, running a mile , and even preparing healthy dishes to support a great cause for the gym . Even though it was a competition , Guerrilla Fitness made it into a fun, friendly and family event, and that is exactly what Guerrilla Fitness represent . August will make it my two year anniversary here and I don't see myself going anywhere many years to come.

Fantastic experience: I’ve whatched the gym grow in many ways than I could possibly share. Terrific place with great people.

Fantastic experience: I was always intrigued at the prospect of joining a crossfit gym and when I moved a few blocks away from Guerrilla, I knew I had no more excuses. I was no stranger to a gym but really had no idea how much of a game changer to my overall fitness crossfit would be. But you hear rumors sometimes about gyms and people getting hurt. Well that is far from the case at Guerrilla where the coaches observe everyone and makes sure that your technique and form is superb and encourages you to be a better version of yourself. There's never any pressure and it's a very family friendly environment. Come one come all!

Fantastic experience: As the first Crossfit gym in NJ, this place continues to improve it's facilities, coaches, workouts and services. All without really raising the cost. An added plus, is it's attracted some really cool people of all ages, shapes and sizes to work out with which creates a phenomenal culture and community.

Fantastic experience: Great gym, great community.

Fantastic experience: The staff here are top notch. They know what they are talking about and are always looking to improve.

Fantastic experience: This isn't just a gym. It's home. This space bleeds authenticity; from the physical look that gives it that gritty feel, to the people that make you excited to get back and work on getting #BetterTogether, to the programming that literally makes that happen, the people that call Guerrilla Fitness home know it to be more than JUST a Crossfit box.

Fantastic experience: The best OG Crossfit gym in NJ
