We miss the community, the people, and the incredible efforts that Jason, Seth, Emily, and all of the coaches here put in to make this such a special gem of a community and fitness house. The coaching team here is exceptional in ensuring the safety of each member, while encouraging everyone to do what is best for their workoit each day. Tim & I have found a new gym that reminds us of Arsenal, but there will never be another. I look forward to coming back whenever we can for a drop-in class or for one of their many bbq's. Thank you for creating such a special, inviting, beautifully strong space, Jason. Less

Very happy so far

CrossFit Arsenal is a great place! They are professional, friendly and they support each individual independently of their level. I have always felt like they cared about me and my goals. I recommend it to all my friends.

Had a wonderful experience here in Emily's "baby and me" class. The workouts were really tailored to postpartum recovery and fitness. Emily is amazing, holding fussy babies and inspiring moms to get a great workout in. Bonus is meeting other moms in the area! Cannot recommend this enough if you just had a baby and want to get back into some semblance of a fitness routine.

Awesome place Definitely recommend it

Love this gym. Having trained bjj at a few different gyms, I can honestly say that this gym has been the best. Jason is very knowledgeable not just in bjj, but in other disciplines as well. Everyone is very friendly and helpful. The pace of the instruction part of the classes are balanced and easy to follow (even with complex sequences).

Welcoming community and knowledgeable coaches. The programming is thoughtful, challenging, and modified for all fitness levels and goals. Plenty of options for class times and/or open gym. All you have to do is show up and hop on the fitness assembly line. You’ll leave feeling pumped up and better than when you came in. Guaranteed.

Great fitness community

Down to earth coaching stuff, and good mix of workouts. I did the 6 week challenge and recommend others to try it as well who haven’t don’t CrossFit before.

I started in June and have been pretty regular. Love how the workouts are set throughout the week. Any day you go in you won’t feel you haven’t worked out because some days there are shorter AMRAPS and some days there are longer like 30 or 40 min AMRAPs.

It’s always a little nerve wracking walking into a new place but everyone there made me feel so welcomed and comfortable. Jason and Seth are supportive and knowledgeable coaches who push you to be better while also providing any scaling you need. They always make sure I have movements down and that I’m challenging myself (no matter what that looks like). They meet everyone where they are and after a month, I am already noticing myself getting stronger. I look forward to my workouts and it’s one of my favorite places to be. I would recommend them to anyone! Less

Awesome people and amazing staff! If you’re hesitant to try CrossFit, give this place a try and see for yourself. You won’t be able to wait for the next class!

Great place to build and maintain a consistent fitness routine. The workouts are thoughtfully programmed with many options for scaling and adapting movements to your skill level.

TLDR: Highly recommend the CrossFit Arsenal for its well-curated full body workouts and great coaches/community! Less

Was nervous getting back into a gym after COVID. Let alone a CrossFit gym because of fear of injury and not being able to fit in. But joining CrossFit Arsenal was one of the best decisions I could make. Super friendly and inclusive gym and one of the best workouts you can get!

Awesome gym for anyone in the Watertown / Cambridge / Belmont area and beyond. Nice mix of beginner, intermediate and advanced people doing well-structured 1hr workouts.

Great space that never feels too tight even with lots of people; and if you’re the only one in class they’ll still do it 1v1. Easy to book at short notice via Wodify app — 7 slots per weekday (morning, noon, afternoon) — worked super well with my shifting schedule. Saturday partner workouts also offer something different. The $200+ monthly fee felt expensive when I signed up, but when you realize it’s like having a personal trainer 15-20 a month, it’s totally worth it! Less

Best CrossFit gym in the greater Boston area. Excellent coaching and close community. No frills, just fitness.

I moved away to Framingham a few years back, but I absolutely loved CrossFit Arsenal when I went there! Jason was an unbelievable coach and owner- so thorough, so helpful, and super fun! My favorite time of the day was going for a workout. Great atmosphere, great community, and great fitness!!

It’s a great place for CrossFit. I recently joined and would highly recommended it for someone looking for CrossFit.

I decided to try out CrossFit to help me improve my running.

For my last marathon training cycle I topped out at 61 miles/week and felt like I was not improving - even regressing- despite all my hard work, which left me feeling pretty frustrated and demoralized. My SIL suggested CrossFit and I can already tell a difference and see improvements in my running after going just 3 times a week for a month and running significantly less miles per week. The exercises are far out of my wheelhouse (I can’t do a real push-up), but the coaches are really welcoming and make you feel supported regardless of fitness level. They will scale back the exercises to a level that’s appropriately challenging for you. I would recommend this gym for all levels - people brand new to CrossFit to experienced CrossFitters. Less

The coaches here are simply amazing – they're not only super knowledgeable but also incredibly friendly. Whenever I needed help with a movement or had questions about my technique, they were always there, ready to give me personalized advice and encouragement. What I love the most about CrossFit Arsenal is the sense of community. It's like being part of a big fitness family. No matter your skill level, everyone is welcomed with open arms. I've made so many friends here, and we all cheer each other on during workouts. Whether you're a seasoned CrossFitter or just starting out, you'll find plenty of support and motivation to keep pushing yourself. The variety of athletes here is impressive. You'll see folks of all backgrounds and abilities, and it's amazing to witness the progress we all make together. I never feel judged or intimidated – it's all about personal growth and celebrating each other's achievements. The facility itself is top-notch, with excellent equipment and a clean, well-maintained space. And they offer flexible class schedules, so it's easy to find a time that fits my busy life. I honestly look forward to every workout at CrossFit Arsenal, knowing I'll have a great time and challenge myself in a supportive environment. If you're searching for a gym that feels like home, where you can work hard, have fun, and be part of an incredible community, I can't recommend CrossFit Arsenal enough. It's been a game-changer for me, and I'm sure it'll be the same for you! Less

Parking is not bad and there is a park parking lot nearby if there are no spaces right next to the gym. It's literally next door so it's a 30-second walk for those wondering. I would highly recommend checking it out and seeing if the vibe is your cup of tea. Less

CF Arsenal offers top quality coaching, programming, and a great community of athletes and CF enthusiasts. Either dropping in or becoming a member, you will get the true CF experience here!

Arsenal is one of the most welcoming and supportive CrossFit gyms I’ve had the pleasure of working out in! Jason and his team of coaches are top notch and every workout is thoughtfully planned out for athletes of all levels. I’ve never walked away from a workout unsatisfied or feeling like I didn’t do enough that day!

Welcoming environment; and will help you regardless of what level you are.

Best CrossFit gym in Boston! Very friendly staffs and tons of awesome people 😱

I initially joined thinking that I'd only do the 6-week challenge as a kickstart to my fitness journey, but by the third week? I was hooked and knew I'd be in it for the long haul! In general, some workouts leave me feeling amazing, while others have me (almost) throwing up mid-workout. But either way, I love the sense of accomplishment I feel every morning, especially knowing that I gave it my all for that one hour! Highly recommend to anyone looking for a fun way to get mentally and physically healthier. :) Less

This is my first CrossFit experience and I have to say that CrossFit Arsenal has me hooked. The coaches are encouraging and knowledgeable, the programming is on point, and the members are welcoming as well as motivating.

Amazing atmosphere were they make you feel like you are at home! Ego checked and left at the door, coachs are willing to help no matter what level you are at! Gym is clean and a solid place to better yourself physically and mentally!

So thankful for the personal training referral to Jason a few months ago. He’s helped me meet my initial goal (deadlift my 75lb goldendoodle) even though I whine about at least half of the exercises EVERY session. He’s patient, knowledgeable, and a GREAT person to have in your fitness journey. Looking forward to more ninja training !

Amazing gym with amazing people

Been a member for a couple of weeks and have had a great experience so far. Looking forward to that hour of fitness daily.

Best Crossfit community I have ever seen. Programs are awesome ! The coaches are super friendly and there for you.

However, 7 years later, I can honestly say that joining CrossFit Arsenal has literally been one of the best decisions of my life. The encouragement of the other members has been consistent, genuine, and motivational beyond words. Many of them have become my friends, and the community aspect of the facility is second to none. The coaches are welcoming, knowledgeable, and positive. They maintain a constant focus on each individual athlete's form during the classes and their overall goals outside of the class environment. I can't say enough about the people and the facility here. It is a program for all ages and abilities. Whether you're a couch potato or a seasoned athlete (or anywhere in between), if you live or work in the area and are looking to make some changes in your health habits, I strongly suggest you do your future self a favor give them a call or drop by to try them out.

Easily my favorite part about living in Watertown/Boston area! Less

The best atmosphere from a beginner to an elite .. just get in there and extend your dash!! Tell Seth I sent you!!!

This gym is very welcoming and open to all skill levels of athletes, from crossfit competitors to complete newbies. The coaches ensure good form and provide thoughtful workouts that are challenging but doable for everyone. I highly recommend it to everyone.

Great crew, great coaches. Felt really welcomed.

Dropped in from out of town for two days. The owners and coaches were amazing and made me feel welcome. Their facilities were clean/organized, and they have everything you could ask for in a CF gym. Great community vibes from this place. Highly recommend. I'm definitely stopping by again the next time I'm in town.

Jason, the owner, and the rest of the skilled trainers cultivate a welcoming environment where anyone from a seasoned, competitive athlete to someone new to fitness can and will get a great workout, learn something new and build friendships along the way. A few years ago, a fire burned down the building which prompted the community and its members to rally and restore the space they love. The new space has expanded from CrossFit and Weightlifting to include Brazilian JiuJitsu, which I love. Whatever your fitness goals are, CrossFit Arsenal is an ideal place to pursue them. Less

I’ve been a member for a few weeks now at Arsenal. Have been to few CFs and this one definitely has that easygoing and team comradery feeling that you hope a box to have. The culture that Jason and his coaches (Seth and Emily) have created is a positive one that definitely helps with improving and pushing yourself in a balanced way. Looking forward to continuing my fitness goals here!

This gym is more than a gym. It’s a community. The workouts are versatile and programming is thoughtful. I know coming in everyday I am going to have a great workout. Having the option to work out more before or after class is also a bonus. Jason the owner is awesome! Highly recommend!

I cannot say enough good things about CFArsenal coaches and fitness friends. Since joining this gym I have become a New England Strong Woman Champion, Masters National Olympic Weightlifting Champion and Masters World Olympic Weightlifting Champion. I did not have much prior athletic experience so you really never know until you try. Without a doubt best gym in Watertown!

Great gym run by great people. I've been a member for about seven years now and have never regretted it. The coaches are very knowledgeable and attuned to individuals' skill levels. Great vibe without any pushiness other gyms possess. I can't recommend this gym enough.

CrossFit Arsenal offers quality coaching and programming. The coaches are knowledgeable, attentive, and really take the time to ensure you’re performing movements correctly and safely. The programming is a great mix of strength training, cardio, and skill work. If you want to be challenged each workout and build strength and stamina, try out a class!

Love this gym! I’ve been a member for about two years: outstanding community, super professional and welcoming coaches, works for any fitness level, great experience.

Been going to this gym since we moved to Watertown a couple of years ago. Great atmosphere and coaches are very encouraging for all skill levels. The community is awesome and they offer different options for group classes including Crossfit, Weightlifting, Rowing (on and off the water!), Jiu-Jitsu etc. Highly recommend to anyone in looking for a place to get there fitness on!

Hands down, best choice I’ve made training at CrossFit Arsenal. VERY friendly coaches and members, who make me actually want to go. I look forward to walking through the doors and always feel amazing when I leave.

I've been going to this gym for a little over two years, and can honestly say that it is one of the most positive and grounding communities I've been a part of. A few things have consistently stood out to me since joining: 1.) Body and gender inclusivity: This gym has a wide range body shape, size, and composition diversity. Every person that uses this gym truly has some difference in skill, and there is a high percentage of female, queer, and POC. 2.) Expert coaches: Each coach at this gym has a solid understanding of how each movement works, why we do it, and how to modify it to meet any athlete where they are at. They know how to help each athlete move with great technique and get stronger. Seth is the hottest. 3.) Solid community building: Everyone at this gym is very positive, and we love watching each other succeed. I know I have formed some great friendships, and there is a strong sense of comradery among each athlete. Less

Truly a wonderful group of people and a great gym! The classes are very accessible regardless of fitness level and the instructors are incredibly knowledgeable and helpful. Would highly recommend!

I have visited many CrossFit gyms in my life and Arsenal is the best! Amazing combination of high-quality coaching, real care and attention to safety, and warm community. Go here if you have a brain!

One of the best parts of my day on a consistent basis. Perfect combination of laughter and challenge. Thanks Jason and Seth

Great gym - Great Community - Great workout!!!

Amazing place where friends turn into family with the added bonus of helping you get strong and healthy. Member since 2017.

This gym is such a big part of my life I don’t know what I would do without it . I’ve been a member for about 6 years now. Really adaptive to all athletes who want to learn more about fitness regardless of your experience. Jason, Seth and all of the coaches all do a great job working with you wherever you are. I was so scared to come into the gym the first time to get back into shape after a long hiatus 6 years ago and Jason was so great he showed up to make sure i was comfortable even though he wasn’t coaching . It was also 6 am. Can’t say there could be any personal touch better than that. Less

Great coaching and programming for all levels of fitness. Whether you're brand new, coming off a break, or at the top of your competitive fitness game, Jason and his team will push you every day to be the best version of yourself. The community is top notch- welcoming, supportive, fun, and always ready to work hard and make each other better. Can't recommend this place highly enough.

First time I stepped foot at the gym I was very intimidated because I felt crossfit was intimidating, but the coaches were supportive and open! The gym environment is positive and motivating. Best thing I ever did !!! Also everyone is fun and nice. Love this place. HIGHLY recommend.

CF Arsenal was my second home when I was living in MA. Great workouts and community! ❤️ Highly recommended!

Diverse and welcoming community. Coaches are knowledgeable and engaging. I enjoy the programming and the availability of open gym hours which were some of the initial reasons I switched over to this gym. Programming is challenging while still accessible for beginners, and well planned out from a longer term view (week by week/month by month).

I am writing this review not as a member but as a former employee. I've worked in the field of strength and conditioning for 12 years, and spent 5 years working at CrossFit Arsenal- longer than I've ever spent working anywhere else.

I am writing this review not as a member but as a former employee. I've worked in the field of strength and conditioning for 12 years, and spent 5 years working at CrossFit Arsenal- longer than I've ever spent working anywhere else. During my time there I always felt respected and was given a tremendous amount of support and freedom in developing my skills in the field. I no longer work there because I've moved out of state and opened my own gym, something I wouldn't have ever been able to do without the encouragement and backing of the members and staff of CrossFit Arsenal. To anyone interested in employment- I highly recommend working at CFA, I've worked at many, many gyms in the Boston area, and working at Arsenal was one of the most fulfilling experiences I've had. To anyone interested in finding a gym- I highly recommend you find a gym that takes care of and respects its employees, that will make a bigger difference in your experience more than anything else. In those regards (among many others), CFA is absolutely top notch. Less

I joined Arsenal about 8 years ago. In that time I have got into the best shape of my life and made some (hopefully) life long friends! It is a great community and program! There is Crossfit, Weightlifting, Rowing and BJJ. Everyone is helpful and welcoming.

Great gym (convenient to my house! :) ), with a VERY flexible class time schedule from 5am to 7pm, ton of open gym time for members! Over the last 6 years Crossfit has transformed my health and fitness and evened out many chronic injuries from decades of rowing (repetitive stress) and other sports.

Great gym (convenient to my house! :) ), with a VERY flexible class time schedule from 5am to 7pm, ton of open gym time for members! Over the last 6 years Crossfit has transformed my health and fitness and evened out many chronic injuries from decades of rowing (repetitive stress) and other sports. All due to the variety and balance of movements involving the entire body, with the skill and flexibility required. Another favorite feature is small class sizes, access to performing the workouts outside, and the inevitable sense of community and supportive atmosphere this brings to the workouts and the gym in general! Less

CrossFit Arsenal has a great setup, dedicated weightlifting area, generous open gym time, and fabulous programming. Coaches here at top notch, and there's a strong community vibe that makes the gym feel like an extension of home. 5/5 would recommend.

Best gym ever! Knowledgeable and supportive coaches, fun and welcoming community, and engaging and thoughtful programming. Everyone/anyone has a place here, whether you’re new to CrossFit or have been at it for years. Can’t recomend it enough!

CFA has everything you would want in a gym and is a very balanced experience.

CFA has everything you would want in a gym and is a very balanced experience. It initially was attractive because of the welcoming attitude of Jason and the rest of the coaches, but I stayed for years there (before moving out of state) because of the excellent coaching, communal vibe, and the overall positive experience. It offers a huge mix of CrossFit, weightlifting, rowing, martial arts that is accessible for beginners and advanced for people that want to compete. The coaches are experienced at both ends of that spectrum. Most classes are a mix of some form of strength and some type of metcon that leaves you feeling satisfied with just an hour’s work. The gym has an incredibly resilient attitude and spirit that is basically: “we’ll be here and we’ll have a workout no matter what.” Expect Jason and company to have great programming and to be open for business rain or shine. Less

Welcoming environment with a nice variety of specialty classes!

I was one of the first members at CrossFit Arsenal. I just wish I lived closer and could still attend classes there. The community Jason has created is something hard to find. Jason is a great coach and motivator. I would recommend this gym to anyone looking to find a community and great fitness. Thank you!!

I’ve been coming to this gym since 2016, so in my 7th year of working out at arsenal. When I first walked into this gym, I was newbie to CrossFit. And I used to be intimidated by CrossFit..

Jason made me feel completely at ease. Over the years, I got better at doing many things, which I’d have not done otherwise. All the coaches at this gym are great and make the workout very accessible or challenging. The programming follows a nice pattern and trains strength, short workouts, long workouts… endurance and stamina building. I’ve made some great friends at this gym. The community is excellent and everyone is made to feel welcome. In addition to the CrossFit classes, arsenal also offers rowing competition practice, and jiu-jitsu. I would totally recommend this gym if you want to workout, develop fitness skills, meet great people and just hang with a cool community. Less

Been a member for 3 years and can’t say enough good things about CFA. As someone with zero CrossFit experience before joining the coaches and community were very welcoming and helped me get ramped up quickly. Classes and programming are accessible for all capability/experience levels. Coaches are fantastic!

I was lucky enough to be able to make this gym my home for a little over a year. The coaches are friendly, encouraging and most important extremely knowledgeable.

Love this gym! Great community and great workouts. Coaches are supportive and knowledgeable. Lots of flexibility for open gym as well.

I started coming to this gym just before the pandemic in January of 2020. I had pretty significant fitness goals I needed to accomplish, which I can honestly say I met and exceeded thanks to Jason, Seth and all of the coaches.

I started coming to this gym just before the pandemic in January of 2020. I had pretty significant fitness goals I needed to accomplish, which I can honestly say I met and exceeded thanks to Jason, Seth and all of the coaches. Having something to look forward to (even if it was on Zoom) every day while everything was shut down kept me sane and kept me on track with my fitness and nutrition goals. I would highly recommend this gym to anyone. They even went out of their way to help me train for a physical agility test that involved a dummy drag using a sled and straps. I also wasn't a strong runner and needed to be, so they pushed me in different ways to improve my endurance and speed. The coaches are amazing and the community cannot be beat. I've been to other gyms as a visitor or on vacation and the vibe was not the same. I've never felt unwelcome or that I didn't belong. There are members from all walks of life, all ages and fitness levels. I've made friends and connections here that I'm sure I'll have for life. I highly recommend checking out the gym. Come in for a trial and you'll be hooked. Less

I was new to CrossFit, and CFA made what seemed complex…fun. The staff is so friendly and makes everyone feel welcomed. Highly recommended to all in the Boston area!!

Place is the best! The staff is great, and the programming is awesome. Highly recommend for anyone of all fitness levels!

We've been here twice, as drop ins. Great experience both times! Seth, the head trainer was great with helpful tips and coaching. Jason, the owner, was delightful, friendly and inviting. Everyone we've met there was also very nice! Also, my daughter loves the gym dog, Finn! We'll be visiting again next time we're nearby!

CrossFit Arsenal is over the top awesome. Jason and the team are funny and personable. The community they foster during Saturday morning partner workouts is just right. Don’t miss out!

I have been going to CrossFit Arsenal and performance for over 5 years now. Before joining arsenal, I had not done CrossFit or any kind of active fitness. In 5 years, I’ve improved a lot and this gym feels like home. There are many offerings: rowing, jiu-jitsu and traditional CrossFit. I typically do the CrossFit and rowing classes and both have worked out very well for me. We row on the water once a year to apply our indoor rowing skills on the water. The coaches are great— very understanding and they really know their stuff. You can make the workouts as challenging as you want, or scale as you see fit— the coaches always provide very good scaling options that allow for a good workout as well as improving on skills. The community events are a lot of fun (and this is the place to be for the year end holiday party!). Definitely encourage CFA if you want to workout at a fun place that provides a great community and many class offerings for everyone. Less

Visiting from out of town. Great people and good Sunday workout. Hero WOD was programmed. Jason was as nice as could be. Will def be back next time I’m in Boston!

As a new dad I’m Always on the lookout for great people and communities. Arsenal is the best! I can’t wait till my little guy is big enough to train with me here. The coaches are amazing and the programming is epic.

Not every gym is worth a return visit, but Crossfit Arsenal is the real deal. If I still lived in the area, I'd be a regular here.

I have loved working at at CFA and the owner, Jason, is amazing!

best gym. no frills, the trainers are great, great community, lots of training/class options.

This is by far the best CrossFit gym I’ve been to. The culture is really great, really nice people and coaches make up this community. I also really enjoy the Jiu Jitsu class. Jason is a great coach and is very knowledgeable about self defense and is really accommodating to all skill levels. Highly recommend coming here and trying it out.

Great local gym! I’ve been a member for almost 7 years. Jason and his staff are well trained, they understand that everyone’s fitness goals are unique and the programming is tailored to each individual.

Dropped in for a workout while visiting my sister and they couldn’t have been more welcoming. I’m 8 weeks into a CrossFit practice, sixty years old and not yet especially strong or skilled in the technical aspects of some of the lifts. Coach Seth and the other athletes took care of me like it was my home gym. Felt great.

I am a drop in that travels across the country for work. I have been to over 20 gyms and this is one of the best! Nice group of people and challenging classes with good scaling as needed.

I absolutely loved this gym! The community is so welcoming and friendly and the coaches are great.

I absolutely loved this gym! The community is so welcoming and friendly and the coaches are great. The programming was really well done and I always loved the workouts. I'd defintiely recommend to anyone in the area looking to start CrossFit or looking for a new gym.

Been going to this gym since 2016. The building literally burned down, the place kept going. Covid happened, we kept going (at home). If you are looking for a low key place to work out and make friends come by.

I've been training at CF Arsenal for a year and love it! The gym has a fun, laid-back atmosphere but programs seriously effective workouts. All of the coaches are great, and the community is welcoming to all fitness levels. I look forward to class at Arsenal every day!

My husband and I have been going to Arsenal for about a year and love it. When we first started, the owner, Jason, let us try out a few classes for free to check it out. The community and programming are what sold us. The coaches are great and we always get a solid workout.

My home away from home! Come for the #gainz, stay for the community and the cute dogs. I’ve been coming here for almost 2 years. Great coaching and great people 😍 I didn’t work out at all during COVID and was very easily able to get back in shape after joining CrossFit Arsenal

I’ve been coming here for about 7 months now. From day one I’ve been met with acceptance, kindness, and grueling workouts. I’m definitely not the “fittest person” but each class I feel encouraged like I’m an athlete with a coach and team encouraging me to be the best version of myself.

I’m definitely not the “fittest person” but each class I feel encouraged like I’m an athlete with a coach and team encouraging me to be the best version of myself. Classes are always fun and welcoming. Don’t know how to do a movement? The coach is going over it? Think you are doing something wrong? A coach is around to help you out. Or just practice the movement. Are you doing something wrong? A coach will stop you and help you scale. It’s not about how fast or how much you lift but are you challenging yourself. I’d recommend anyone to come give it a shot. Even if you haven’t worked out in decades, you’ll feel at home here. Less

The community and coaches at CrossFit Arsenal are top notch. Great atmosphere and tremendous workouts that fit all skill levels. Would recommend to anyone that is interested in CrossFit.

10/10 experience!! First gym I tried in MA and I LOVED it! The coaches are very knowledgeable and helped me improve each day. I’ve been a member of 5 other CrossFit gyms, and CrossFit Arsenal had the best programming by far. On top of PR’ing all of my lifts, I’ve made lifelong pals along the way!

What a great place to get fit! Great community, awesome coaches, fantastic athletes, friendly environment, overall 10/10! You cant go wrong with signing up at CFA! The coaches make it very fun to be there and also challenge you to be your best self everyday! Highly recommended! SIGN UP TODAY!

I joined CrossFit Arsenal a couple of months ago and have been enjoying it so much! I’m restarting my fitness journey after a few years and couldn’t be happier to be doing it at this gym. Great coaches, great energy, awesome community. Best part of my day!

CrossFit Arsenal & Performance is a down-to-earth, welcoming fitness community. The programming is challenging yet approachable and the coaches are knowledgable and supportive. Whether you’re looking for CrossFit, weightlifting, rowing, or Brazilian Jiu-Jitsu, Arsenal is the place to be.

Great coaching, programming, and overall atmosphere! Coaching staff takes the time to ensure everyone understands the workout and can do a variation that best suits their ability. The programming is thoughtfully curated unlike other boxes in the area that I've experienced. Best reason to get a great workout in at 6am.

One of the best, most personable CrossFits I’ve been to. Hometown vibe and great community. Been here multiple times and Jason the owner curates a great vibe. Highly recommend!!

At 50 years old and 10 plus years removed from doing anything athletic, to say walking into a cross fit gym was out of my comfort zone would be an understatement.

Saturday Competition Class was awesome! Coach/athletes were all extremely welcoming, personable and made me feel right at home! Very competitive but very fun at the same time! If you are looking for a place to get a good sweat in and meet some amazing people this is the place to be!

Amazing place. I was never a gym kind of person but once I found this place I have been going there for over 3 years now. Great fitness programs. I have seen a big difference in my body and my mental health. All coaches are great and It’s like a family there.

Love this place! The environment, the workouts, and the coaches. The coaching staff and the culture they’ve created is what makes this gym so unique. I’m so glad i found this gym and community. I’d give it 10 stars if I could!

This staff and gym helped me lose 20 pounds in just over 9 weeks. 10/10 I would recommend this gym.

I had originally been going to CrossFit Arsenal to get ready and fit for my incoming rugby season. I enjoyed it so much that I kept going back. They offer a lot of different programs, the coaches are great and supportive and the members are nice to train with.

They are amazing! They really care about your needs! Thank you! I Highly recommend!

I only have great things to say about CrossFit Arsenal. I've been to many gyms, but this one is by far the best! Everyone is incredibly friendly and welcoming, the coaching is excellent, the space is fantastic, and there is a wide variety of classes and workouts available, from weightlifting to jiu jitsu to rowing. If you're looking for a gym, you should definitely stop by and check it out!

I can't recommend Crossfit Arsenal highly enough! My wife and I joined the CFA community this spring and have been welcomed with open arms. Jason and his coaches are top quality and make sure that everyone is welcomed and supported. Give it a try!

The gym has incredible coaches and an atmosphere that helps you feel at ease and ready to do your best. Everyone there is supportive and want to see you improve and succeed.

Jason has been a tremendous help (trainer and business rep). He’s very helpful, calm and the perfect temperament for someone (myself) to get introduced to cross fit. I can’t wait to start!!

He has the heart of a lion and knows how to inspire. His programing is always fresh and innovative. He’s very creative and he’s always bringing something new, whether it be variations to warm-ups, recovery methods, or contests/social activities at the gym. He’s got a great sense of humor, too, and manages to impart a lot of knowledge about fitness while keeping you entertained. -The other coaches are phenomenal as well: Jamie is a maestro with incredible skills and depth of knowledge. Seth and Adam are phenomenal athletes and great motivators. Christine is tremendously positive, kind, and encouraging. I also found Julie’s weightlifting/Olympic class on Saturdays highly beneficial. The “All Fitness, All the Time” mentality: - CFA lets nothing stand in the way of the daily pursuit of gains. CFA stays open through every blizzard, nor’easter, etc. In the middle of one blizzard, I trudged my way to a noon class and was the only client there. I did part of the warm-up on the ski erg in front of a window with heavy snow falling outside! Jamie led me through the rest of the warm-up and WOD the same as if he were leading a full class. I was impressed with that. Now CFA faces a bigger challenge, to respond to the damage from the recent fire, but I have no doubt that they will respond with gusto and that the fitness will go on. Community: -The size of the box is cozy and there’s a great energy. Class sizes are small. -Great atmosphere for events like Murph and the Open. -Smart, motivated people who support you and help you to get better. In short, of the boxes I have utilized in Florida, Pennsylvania, Peru, this one is very special, and I don’t know if I’ll find another that can match it. Less

I’ve been at this box for about a month now and couldn’t be happier. The workouts are designed to be scalable and logical in that if I choose to come every day, I may be sore, but I’m not overworking the same major muscle groups/the same movement on consecutive days. This has allowed me to be much more consistent with my training. The coaches are terrific, encouraging, and supportive. And the com... More

I couldn’t recommend it more! Less

CFA is an amazing gym and community. The coaches are very knowledgeable and the people there are very friendly! The classes are fun and challenging, but can be scaled for beginners or experts! Tons of equipment and always a fun time. Highly recommended!

From the first day I walked into CFA over two years ago, it felt like home. The coaches and the members are some of the most caring people I’ve ever gotten to be around. CFA really finds that sweet spot of pushing you to your limits, but just because they know what you are truly capable of. Can’t recommend enough!

I can’t say enough good things about this place. I’ve been doing CrossFit for over seven years and have belonged to five gyms over that time span and Arsenal is exceptional. I’m nowhere near the fastest or strongest person in the gym, and I’m probably not the person you picture when you think of “CrossFit,” but I always felt appropriately challenged, very well coached, and totally welcome at Arse...

I’m nowhere near the fastest or strongest person in the gym, and I’m probably not the person you picture when you think of “CrossFit,” but I always felt appropriately challenged, very well coached, and totally welcome at Arsenal. The coaches are knowledgeable and friendly, the programming is excellent, and all the folks who come to the gym every day always felt like an extension of my friend group. Whatever your fitness level, whatever you think of CrossFit, give this place a shot. Less

Nice

Great coaches, awesome tight knit community, fun unique events!

Amazing box with an amazing owner... Jason is the man. Very inclusive environment and community!

Been over 2 1/2yrs since I stopped cross fit. I came cack and i am on day 5 working out! I wish I joined earlier. Great owner/coach that cares for his athletes from beginner to experienced. Great coaches who all bring amazing personalities and a lot to the table. Very friendly, and family base atmosphere!

excellent. Very cozy atmosphere. Very receptive teachers. The Workouts have intensity and great volume. Vida Longa CFA.

I love this place

Great coaches and community! From beginners to pros, there's big support coming your way all the time. Definitely the best CrossFit gym in town.

So glad I joined crossfit arsenal. Got tired of usual gym routine and not seeing any improvements. The coaches here are very attentive and want you to get stronger. Very fun group and definitely has a community feel. Look no where!

No better box. After doing CrossFit continuously for 11 (eleven) years, in 7 cities, I have not found any better box. High quality equipment. Coaches with high levels of knowledge coupled with the ability to motivate. A small-gym atmosphere. At times relaxed, at times intense. Want gains? Don't miss CrosssFit Arsenal.

Awesome group of people! Very welcoming and instantly felt at home. Coaches are very accommodating, too. Great spot for visitors looking for a drop-in. Would recommend to anyone and hope to come back 💪💪

love this place!! the workouts are amazing, and the trainers are some of the best Ive had the pleasure of working with.

An amazing place where I began my Crossfit journey! Jason and the staff are always attentive and helpful. The programming is excellent and never boring.

I'll miss CFA, but will continue with Crossfit as I return to DC. Between the supportive community, the challenging workouts and the outside events organized through CFA and its members, you cannot go wrong checking out this place! Less

I've been a member of Crossfit Arsenal since January 2016. I have worked out/exercised since I was a teenager but felt the need for a change. From the first class I took, I was hooked. Jason, the owner, has created a tremendous environment at his gym in which I feel challenged every time I'm there while at the same time supported by the entire community. Jason has a tremendous amount of personal knowledge and is a great teacher. His staff of coaches are also talented, attentive, smart, and encouraging. The programming of the classes is well thought out and provides me with an awesome workout every time I go. This is the best gym that I have ever been to, and I have tried a lot. I highly recommend that you come to Crossfit Arsenal. The results are undeniable. Less

I absolutely love this gym! The owner is very experienced in the art of fitness and does a great job with the programming. I had been doing CF for about 1.5yrs before taking a 6 month break due to an injury, and I started working out at CFA after my rehab. Since then, I've PRd all of my lifts by almost 10%, which is huge for a 6 month period. Jason also does a great job with people that are new t... More

Since then, I've PRd all of my lifts by almost 10%, which is huge for a 6 month period. Jason also does a great job with people that are new to CF. He is excellent at communicating with his clients, and you really get to learn a lot when you take his classes. On top of all this, theres a great sense of community here. Every helps each other get better and we try to do social events fairly frequently. Overall, CFA is a great gym, and I recomend it to anyone who wants to start CF, or just get in better shape. Less

I started CrossFit about 2 years ago at another gym (AKA Box) but, I switched to CF Arsenal about a year ago. It has been a very different experience. First, I did not come from a fitness background. Second, I’m a little older (40ish) than what I perceive to be the average CF age. Lastly, I'm not super great at making friends.

I started CrossFit about 2 years ago at another gym (AKA Box) but, I switched to CF Arsenal about a year ago. It has been a very different experience. First, I did not come from a fitness background. Second, I’m a little older (40ish) than what I perceive to be the average CF age. Lastly, I'm not super great at making friends. At Arsenal, I found the smaller gym size and classes to be a perfect fit for me and my personality. The people here range from great athletes, to folks just trying to get a sweat on. All of them have been very friendly and zero ego. To top all of this off, Jason is an attentive coach and genuinely cares about the members. He is always trying to make Arsenal a better place for us. The other coaches all follow his lead in the same spirit. Community is often mentioned with CrossFit. Arsenal’s community is real and positive. If you’re on the fence, get off it, and come by. Less

CrossFit Arsenal is everything that I've ever wanted in a gym because of its coaching staff and community. I was one of those people who swore that they would never do CrossFit. I joined in December 2015 because I was missing something in my workout routine. My only regret is not joining sooner. The head coach and owner, Jason, is absolutely fantastic.

CrossFit Arsenal is everything that I've ever wanted in a gym because of its coaching staff and community. I was one of those people who swore that they would never do CrossFit. I joined in December 2015 because I was missing something in my workout routine. My only regret is not joining sooner. The head coach and owner, Jason, is absolutely fantastic. He is extremely knowledgeable and his programming drives results. Jason's entire staff of coaches is equally as amazing. I was most nervous joining CrossFit because I had heard/read about all the injuries people get because form is forgotten. This could not be further from the truth at CrossFit Arsenal. Every class begins with a warm up and then skills portion of the workout where every movement in the WOD is reviewed. CrossFit Arsenal really shines not only because of its excellent coaching staff, but also because of it's member community. I have never met a more supportive group of people in a gym setting. The community immediately welcomes new members. I cannot say enough good things about this gym and highly recommend it. Whether you are a seasoned CrossFitter or completely new- this is the place for you. Less

I've been to a few xfits and this is my favorite so far. It 100% comes down to the quality of the coaches and everyone here is top notch. Besides being experienced and knowledgeable, I genuinely like everyone of them and would consider them my friends in and outside the gym.

Great fitness community here, with most people coming at least a couple of days a weeks so you get to know everybody. Mostly young professionals working in the area.

Great fitness community here, with most people coming at least a couple of days a weeks so you get to know everybody. Mostly young professionals working in the area. The owner of the company, Jason, did a great job of helping customize my own workouts during classes before I was ready to step up my workouts with the rest of the class, so don't worry about your own fitness level. The actual facility is on a nondescript little side street and it's easy to miss, but it's certainly worth looking for. This is my first CrossFit ever, and I'm really happy with it. Initially it seemed a tad pricey for a gym, BUT really you get so much more than a normal gym where no one knows anyone else and where you can give up early and no one will know about it. At CrossFit, people cheer each other on and no one gives up. I highly recommend this! Update: Certainly one of the greatest decisions I've made in a long time has been joining CrossFit Arsenal. The people are really amazing and so are the results! I'm certainly in the best shape since my college days, if not better. I'm still learning new techniques every week and being encouraged to work harder (still working toward the free-standing hand-stand pushups but getting close!). Thanks, Crossfit Arsenal! Less

The coaching here is simply the best. The coaches are always giving out pointers and tips to help you improve your form and your performance in an incredibly positive way. The emphasis here on form first is one of my favorite things about the gym and coaching philosophy. And there are always improvements being made to the space! Gains for everyone!

Amazing coaches, owner, and community. I'm a former athlete, in the best shape of my life, and I've never had more fun working out

Great facilities, friendly members and highly competent coach!

Great place, community and coaches.

I am the person who said she'd never try Crossfit. I religiously made fun of my friends who whined about the WOD and spent hours talking about Cleans and Snatches. The truth is, I was stuck in a boring fitness pattern and decided to try a free session of Crossfit to get me out of a rut.

The truth is, I was stuck in a boring fitness pattern and decided to try a free session of Crossfit to get me out of a rut. After going to a few CF gyms in the Boston area I found CF Arsenal and was hooked. Jason is an amazing coach and trainer who is patient, kind and devoted to helping you become the best version of yourself. He will challenge you while still making sure every rep is done with proper form. The CF Arsenal community is very welcoming and will cheer you on even when they're out of breath. I honestly can't recommend Crossfit Arsenal enough. Less

Jason and CrossFit Arsenal were truly transformational. I had little experience of CrossFit and was sceptical at first but Jason was patient, kind and within a few weeks I was doing things I didn't think possible. Now I absolutely love it. Would recommend to anyone and everyone to get involved.

Jason Gee has cultivated Crossfit Arsenal to be a fun, challengingly effective, and safe gym welcoming to all levels of athletes. I wake up every morning excited to go!

Great great Crossfit gym with an owner and coaches who really know their stuff. The facility has all of the equipment you'll ever need and There's so much parking.

Jason is the man!! Really smart coach and all around great person. Challenging programming, wonderful people, and great facility. Highly recommended to everyone and anyone.

Great Gym! I had trained under Jason when he was working at another local CF Gym previous to him opening this spot.

Jason is one of the best CrossFit coaches I've ever worked with. He has a gift for explaining and then re-explaining (when needed) to make sure that the athlete really masters the movement. The quality of a CrossFit gym depends heavily on the coach, and Jason really makes CFA worth it. I have rarely seen someone work as hard as Jason does to make the member experience truly special.

Awesome CrossFit gym! CF gyms are only as good as their coaches and Jason is one of the best. Highly recommended for beginners and experts alike.

Great community, attentive coaching, convenient location. What more could you want out of a crossfit gym!

Jason and CrossFit Arsenal are amazing! He is an excellent coach with a great eye for movement, and truly cares about every person who walks through his door. The gym has a really friendly community and everything you need, whether you're a new or experienced CrossFitter. Go check it out!

Great
