The Best Gym In Watertown

CrossFit Arsenal - More Than Just a Gym, It's Family! ⭐⭐⭐⭐⭐ From the moment I arrived in the US, joining CrossFit Arsenal in Watertown was one of the best decisions I made. It instantly became my home away from home, and I've thoroughly enjoyed every single aspect of my time here. The classes are well-coached and engaging, pushing me to new limits while always ensuring proper form and safety. Beyond the daily WODs, the specialized seminars offered invaluable opportunities to deepen skills and knowledge. CrossFit Arsenal is so much more than just fitness. The parties and social events were always a blast, a testament to the incredible community here. The crowd is genuinely fantastic – supportive, encouraging, and full of wonderful people from all walks of life. This isn't just a gym; it's an Arsenal family, and I'll carry a piece of it with me always. Highly, highly recommend!

Arsenal has been an awesome place for fitness and camaraderie. Solid facility, friendly and knowledgeable coaches, and a great community. Highly recommend if you’re looking for place to check out or continue on your CrossFit or Jiu Jitsu journey!

Dropping in from out of town. It’s a really solid gym and has everything I needed. Jason is awesome and very welcoming. Will definitely be back!

When I was looking to join a new gym nearby, I relied heavily on Google reviews to learn about this place. Now, after a year of training here, I can absolutely confirm what everyone said - the community here is incredible! The coaches are knowledgeable and supportive, the space is well-equipped, and they regularly host events that bring everyone together. I've joined their BJJ classes too, which maintain that same amazing community vibe. Would recommend to anyone looking to start their fitness journey. P. S. This photo is from a recent weightlifting seminar!

CrossFit Arsenal has been home gym for close to a decade now. I lost a bit of weight here while getting stronger, faster, and more importantly, healthier. It’s a great place to be if that is also your goal. This gym is set up with multiple CrossFit classes if you don’t what to do with programming or workout. A lot of people do come in to do their own workout too. Pictures included a picture of us learning about Olympic Weight Lifting.

Great coaching and lovey members. Thanks for welcoming me during a drop in class!

I will ALWAYS love Arsenal. This was my gym from 2014 to 2023, and I miss it every day. My husband and I moved from the city, and the ONLY hard part about leaving was needing to leave this gym. 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.

Very happy so far

Arsenal is one of my favorite places on earth, and is an incredible community of inviting and motivated people! Attending classes at Arsenal guarantees you will have at least one great hour every day, and will provide you with an opportunity for personal growth across multiple facets of your life. The staff at the gym are top notch people who will always go out of their way to make sure your experience is positive, and according to my parents the owner Jason was “a very charming man” when they saw him on local news. Going to the gym is a great way to get out of your comfort zone, meet new friends and make small improvements every day!

I love coming here! I came to drop 10lbs to fit in my wedding dress to zip. I did that and i stayed for the community. The music is great the workouts are tough. Emily, Seth and Jason are great coaches that really watch and to the best of their ability make sure you don’t get hurt. I still manage to walk into walls … I really like how they push you even though i find it rude that Jason told me i had to actually bend my elbows to do a push up

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. They provide great instruction prior to the skill/workout and work with you to find the appropriate modifications for your skill level. There are many class offerings throughout the day, in addition to class on both Saturday and Sunday. Lastly, gym members were welcoming and helpful. Glad i was able to call this gym home and will miss this wonderful community.

If you’re a parent juggling between family and work life, like me, don’t forget to invest in yourself too. I went from couch to CrossFit Arsenal about two weeks ago and already know it’s the best decision I’ve made in a while. The coaches demonstrate movements at the beginning of class then proactively provide guidance during the workout of the day. The members are down-to-earth, kind people. I am excited about losing weight, taking time for myself, building the strength/energy to keep up with my boys, and reclaiming long term health here. TLDR: Highly recommend the CrossFit Arsenal for its well-curated full body workouts and great coaches/community!
