To be clear: I have…read morebeen coming to this gym for over 5 years. When I first arrive, I was an overweight, short, and weak Asian man in his early 30s in need of a healthier life style. This gym help me lose 20lbs in the first year and another 15 the next year. I gotten a lot stronger, faster, and healthier. I'm very thankful for Coach Jason, Seth, and Emily. What I really enjoy about this gym is the members are very encouraging. They push you to finish your work out, not give up, and continue to participated. This isn't the type of gym that's competitive but the one to push better health. I never heard of crossfit when I first walked in the gym Here's what stayed the same: It's still a bit pricey at $197 at a full membership. There is a slight discount for students and first responders. There are drop-in packages if you don't want to commit for a full month. I honestly did just crossfit and it was very effective. There is also a weightlifting class that just restarted. Please contact the gym if you haven't done crossfit before because there is a trial class. Here is what have changed: The gym added rowing and Brazilian JiuJitsu class for the evenings ( I think 6:30 and 7:30 respectively and on certain nights). Brazilian JiuJitsu is really fun. If you are looking for a new gym or just wanted to work out, I highly recommend this gym. I am a person that usually don't know what I am doing but all the coaches really help here.

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!

This CrossFit gym has its pros and cons:…read more Pros: Really nice founders and trainers. Everyone that runs or is employed by the gym has a good attitude and is patient with new people. I really get a good vibe from them! The gym is clean, there are plenty of bars, bumper plates, etc. The workouts are really good. I lost a lot of weight and got stronger for the couple months I went to the gym. They have a good progression and I have used what I learned there to train on my own. I learned a ton about good form in the most important exercises: Squats, deadlifts, etc. Again, everything I've learned I can carry on to where I train now. Also, there are all kinds of fun workouts like rope climbs and sprints that I never would have done on my own. Cons: The trainers vary in quality. There are some that will work with you on your form and others will just yell things out during the workout like 'you got it' or 'nice work'. I prefer the kind of trainers that give me very specific help rather than the generic kind. The people who train at the gym are not very friendly or welcoming to new people. I can't tell you how many times I smiled or said 'hello' to one of the other people in my class and they ignored me. I ran into a group of them having a beer after class once at a bar nearby and I said hello. Once again, ignored. There was another time they were talking about a book club they were having and I asked them what book they were reading. Silence. Not the friendliest CrossFit box if you don't fit in. Very cliquish. Also, many of the students are unnecessarily competitive. I guess that's fine for competition but what's the point in being competitive with some new people who joined to lose some weight and get stronger? In sum, come here for a great workout. I want to reiterate that the people who run the gym are great, but I can't say the same about the people who actually train there. Try all the trainers, pick your favorite and just put your head down and do the work!

Quality coaching, good facilities and location (just across the street from HBS, plentiful parking), but most of all, the members are all wonderful. All inclusive, supportive members who care about your progress and your happiness. Neal is the original founder of CrossFit in New England. His network is expansive, and most gyms that have opened in Boston began as members of his gym. Most other gyms in the Boston area are much larger, many more classes, many more members. The more intimate size of the gym is why I keep coming back. Worth every dollar and minute.

The combination of the recommended diet and personal attention in the workouts are the key to success. Ashley's expertise as a personal trainer is evident. I have been able to increase my flexibility, strength and balance. The workouts are always different and the 30 minutes goes by quickly. Today the studio sponsored a Zumba class at no charge. It was a lot of fun and it was obvious the staff put in a lot of work to make the day a success. I highly recommend GISW.

I've now been to several CRGs and I like this the best. It's by far the largest. And remarkably clean for a chalk-filled gym. I guess the HVAC system works very well. And one cool feature which I've pictured. A ramp. Go to the bottom and climb up. Side routes are softer, while the overhung routes are much more difficult. I've never seen anything like this in a gym. Very nice. Hoping to come back here again next time I'm in town.

Great classes at a no frills gym. Great exercise to add into your mix. And you get to punch a bagread more

Hello, This has been long overdue!…read moreI have had the pleasure of going to Nontantum Boxing Club (NBC) for over two years, and this place changed my life. The club loves teaching others of all shapes, sizes, and ages boxing. The old-school vibe is amazing and the people there are supportive, it has become my second home. The club holds classes with cancer survivors and through this club, I joined the Haymakers for Hope a cancer charity to "Knock out Cancer." The owners are reachable and accessible for questions if need be. I LOVE THIS GYM more than anything, I call it my second home. The monthly rate is more than reasonable compared to other places. They also hold a class for children on Saturday mornings. (It's cute to see the kids' box) The club is open 7 days a week with morning and evening classes. Can't say enough things about this place!!!!!!!!!!!!!!

This review is for "the Remix" class at Sweat Box. It's interesting...wierd-interesting, not…read moreinteresting-good. I bought the Living Social/Groupon thing for 5 classes here. After my first class, I'm not sure if I'll be back. Si Fu K.L. Brown (the instructor) is like a mix of Billy Blanks with his Tae Bo body but a little bit of Charlie with his angels. You start off the class with a bunch of core exercises including 100s of mountain climbers, push-ups, sit-ups, etc. In the middle of these exercises, these "angels" come out and do something like a show & tell to the class, showing off their capoeira or whatever it is that they are doing with Si Fu. It's wierd. At multiple times in the class, the other students and myself are just standing in a circle watching this show & tell. Then at the end of the class, it felt like these "angels" were recruiting for more angels. I felt like I just paid money to listen to a good Rihanna/Madonna remix and watch some girls with sweat bands pretending to fight each other. Hmm....I guess if its pretty amusing after all.

I got introduced to the class when I saw the deal on groupon. I went to all the 5 classes and got…read moreamazing workout from the Woman Basic class. I also checked out the Hip Hop remix class but found that is not my cup of tea. The hip hop class is a little weird where you spent 20mins of core workout, followed by some dances moves which is fun. But then there is ~5mins of just standing and watching the 'angels' performing. I guess I was not so interested in watching and prefer to do the workout myself. The basic class is the one to go to if you are interested in boxing training and get incredible workout. I love it so much and ended up buying more passes from them and will make this part of my weekly training. I almost wish they offer more classes like this during the week instead of once a week.

They do have auto-belays though, which is nice and unusual. Only downsides are that this place is really small. I think maybe 50 routes. And except for one area the walls are very short, maybe 30 feet high at most??? The grades looked slightly soft for all but the higher 11s and 12s. But if you want a simple easy place up to, definitely come here!!!
