Testimonials
Real Reviews from Watertown
Liz SoutterGreat coaching and lovey members. Thanks for welcoming me during a drop in class!Sarah HigginsI 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.CatarinaCrossFit 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.Denis TiteFamily!Elise RessaHad 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.Aleksandr NatovAwesome place Definitely recommend itDennis TeeterLove 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). The rolls are competitive, yet slow enough to practice techniques. A true family atmosphere.Jesse BeaganWelcoming 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.Will JenkinsAwesome 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!
