My wife and I have been doing CrossFit since 2012 and found KSCF when we moved here in 2018. We…read morehave been members since and to be quite honest it has become a home away from home, even after moving from Kendall Square to Davis Square where we have closer options available. Kendall Square CrossFit is a great location, a supportive and energetic community, and has great coaches that prioritize safety and range of motion/movement to heavy weights and maxxing out. Everyone is engaged, friendly, and supportive with no big egos or difficult personalities present in the classes no matter the level or how long you have been a member (we get a lot of drop-ins as well). Everyone is there to get better and achieve their goals and there is not a bunch of nonsense and power struggles that I have seen and experienced in other gyms. The equipment is well cared for and maintained and while not everything is present there for a dedicated games-style athlete, there is plenty of equipment to get your typical CrossFit-style workout in (except the assault/echo bike, but those things can stay in the trash where they belong :P). This is all managed despite a smaller space than some other gyms, but the coaches manage it so there is no danger of injury or overcrowding due to space issues. It's essentially two racquetball courts with a wall knocked out to give you an idea of the size of the space. It gives it a cool feeling with the vaulted ceilings but can carry a pretty heavy echo when instruction is going on... which also happens when the music is played which makes it really loud (which I like). Members also get access to the CAC amenities such as the locker rooms, showers, saunas, and other equipment. You seem to get more than you do for the same relative cost at other CrossFit gyms in the area where many don't have showers, saunas, or even lockers. We have been very pleased with our 7ish years at KSCF and despite having changing situations and evaluating options to go elsewhere, we never left or think about leaving. It is truly a pillar in our daily lives and the membership has led to many friendships in (and more importantly outside) the gym. I can't recommend KSCF enough to anyone in the area looking for a way to better themselves and not worry about how they are viewed while beginning or continuing their fitness journey, even if you are new to CrossFit or just want to see what it is all about!

I've been to my share of CrossFit gyms around Cambridge, but nothing quite prepared me for Kendall…read moreSquare CrossFit. Located in the heart of Cambridge's innovation district, this facility seems to have missed the memo on both innovation and basic maintenance. Walking into the gym feels like stepping into a time capsule -- one that's been gathering dust for months. Every piece of equipment wears a visible layer of grime, from the dumbbells to the rowing machines. When I asked staff about the cleanliness standards, I was told, matter-of-factly, "We clean, but dust flies around." It's the kind of response that makes you wonder if management has given up on the concept of deep cleaning entirely. The exercise floor mat tells its own story of neglect. Fraying edges and splintering surfaces turned my hands into pincushions during floor exercises -- a recurring issue that happened in nearly every class I attended. For a sport that demands athletes grab, grip and ground themselves constantly, having equipment that actively wounds participants seems counterproductive. Then there are the towels, which possess all the softness of medium-grit sandpaper. Using them feels less like drying off and more like an aggressive exfoliation treatment. I developed rashes that took days to heal -- hardly the post-workout glow I was seeking. The ventilation system appears to be more theoretical than functional. The air hangs heavy with the accumulated sweat of countless workouts, creating an atmosphere that newcomers will find overwhelming and regulars have simply learned to endure. It's the kind of environment where you find yourself taking deep breaths before entering, knowing fresh air will be in short supply. Space is at such a premium that peak-hour classes become exercises in human Tetris. Athletes regularly collide during movements, and navigating around classmates becomes part of the workout itself. Adding to the puzzling equipment situation: unlike every other CrossFit gym I've visited, this one doesn't provide jump ropes -- forcing members to bring their own or go without. The coaching staff presents the starkest contrasts I've encountered in fitness. Most instructors seem to view their teaching duties as an unfortunate interruption to their day. Jimmy Kuykendall projects such visible disinterest that his lack of enthusiasm becomes contagious in the worst possible way. Meaghan Shea displays a sense of deep apathy that permeates her instruction, making participants feel more like an inconvenience than paying customers. Stavroula Papdopoulos brings energy but delivers instruction that's often incomprehensible, leaving participants to guess at proper form and technique. But then there's Nery Amaya, who stands out like a beacon in this sea of mediocrity. Amaya demonstrates genuine expertise, offers clear instruction, and maintains the kind of motivational energy that makes the difference between a good workout and a great one. His presence raises an obvious question: how does such a skilled coach remain in an environment that seems designed to crush professional spirits? Having sampled other local options like Invictus and CrossFit Somerville, I can confirm that these standards aren't universal to the sport. Those facilities demonstrate that it's entirely possible to maintain clean equipment, breathable air, and engaged coaching staff. Kendall Square CrossFit feels like a missed opportunity in a neighborhood known for innovation and excellence. The gym charges competitive rates for what amounts to a substandard experience, saved from complete failure only by one instructor's determination to maintain professional standards. For potential members weighing their options, I'd suggest visiting during peak hours to experience the space constraints firsthand, and perhaps bringing your own towel -- and jump rope. For anyone with other options in the Cambridge area, I would recommend staying as far away from this facility as possible. Save your money, your health, and your time -- you'll thank yourself later.

The coaches like Brian, Larry and Abby are sticklers for technique, but as a result help you build safer foundations for movements. For example, I hadn't realized that I was basically throwing myself at the wall for handstand pushups when there was a much safer way of getting up on the wall, which then later allowed me to complete hand stand walks!

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!

I was…read moretruly excited to experience the personal attention since they cap their classes at 10 and my crossfit home gym does not have a cap. Conveniently located near the hotel, it was short walk and easy to find. The gym is a the typical box, gritty and the look of a hard workout is about to happen here. I was the first to arrive and immediately greeted by coach Eric. He quickly checked me in and I made them aware of needing modifications on certain movements. He gave me some stretches I can use. The class was composed of warm up/agility, stretching, strength training and finally the WOD. The coach did not assume I knew the movements which I appreciated and he showed us proper form for every movement. We used agility hurdles to warm up with burpee penalty for knocking down the hurdles, which is good practice in discipline. I felt warmed up after the hurdles having to fulfill burpee penalties twice. Then we used foam roller, kettle bell and racquet ball to warm up and shoulder mobility. We spent a good 20 minutes for warm up and mobility which is helpful and much needed. Strength training was another 20 minutes of push press. The coach was helpful in making sure our form was correct and efficient. I felt more accomplished in getting the form right and he made sure of that. Finally, our WOD was a challenging chipper with 3 movements at high reps. It was daunting at first and I was gassed but I got through it with the coach's encouragement. The coach was motivating without being militant. It is obvious the gym does well in providing top notch instuction. Limiting their class size provides the individualized attention needed to avoid poor form and injuries. CFF is great for any fitness level and makes crossfit an attainable activity for anyone.
