Let's start with the best thing this box has going for it and work down. PROGRAMING: KOA does an outstanding job here. They program in cycles, each cycle focusing on either strength, gymnastics, olympic lifts, or conditioning... Hell there are even a powerlifting and CF competitors programs for members who compete in such events. You can always expect a metcon as part of your wod though, but depending on the cycle KOA is in, the work before the metcon will vary. This has allowed KOA to produce strong, conditioned athletes. COACHING: KOA's coaches know their stuff! You only need to watch a member move to see how obvious this is. Great coaching produces great movers. Additionally, each coach takes the time to prepare your body for the wod ahead with specific mobility drills and or warm-ups. FACILITY: by far one of the better equipped boxes in the area. They have everything from lifting platforms, to lifting blocks, axle bars, oly bars, rowers, assault airbikes, ghd's, sleds, rigs, rings, ropes, dumbbells, kbs, slam balls, medballs, and much much more. KOA also occupies a storefront and it's storage warehouse, so there is plenty of square footage. CLASSES: You want classes, KOA has got classes! As I mentioned earlier KOA occupies a storefront and its warehouse which are connected but separated enough that KOA is able to run 2 classes at the same time. What this means is that from 5:15pm to 8:15pm (there are early morning and mid day classes as well) KOA starts a class every 45 minutes, one in the front and another in the back. KOA also offers a gymnastics and competitors programs free of charge to members. There's also an oly club that participates in competitions (also open to members but requires a lifting singlet to join). COMMUNITY: KOA has a lot of members, because of this it is impossible to have that small box feel where everyone knows one another. However, KOA is not without a strong sense of community. Members throw parties and invite everyone, KOA has plenty of in-box events, and they are very active in supporting the CF community by participating and or hosting friendly box vs box throwdowns and charity events. In the end I recommend you drop in at several of the few surrounding boxes so you can make an informed decision about which box is best for you. But I do feel that KOA offers the best package in the area. As for addressing the comments below, I've been a member of KOA for over 6 months now and I can tell you with 100% confidence that the negative reviews this place has received on yelp don't hold up. I've never been pushed any products, although a few of the athletes do use the same brand, but they do so because they feel it works for them and I've never seen them push it to other members. Like Miguel said, nothing but positive life changing experiences here. And yes, Miguel did leave, but he did so to become a coach at ECC. read more

Aside from being an amazing place to reach new heights physically, KOA's best quality is that is strives to create a positive atmosphere for all of its members. There are no egos, and everyone (coaches and fellow athletes included) are as happy for you as they are for themselves. There is a special bond that forms from doing workouts together, that I wouldn't of ever thought was possible. Whether you're a former athlete trying to get back into it, an elite athlete trying to reach the next level, a casual gym goer, or an athletic novice like I was, this is the place for you. Koa will push you to be the best you can, and this is not only physically. They teach you to be mentally tough and to keep striving to improve. There is a mental toughness, determination, and aggression that you need to be able to lift a bar over your head. I found myself unknowingly taking the same confidence into other every day things in my life. You learn that things you never thought were possible, are very possible if you put a plan together and execute it. When I started, I could barely lift the bar over my head, couldn't do a pullup, and was out of breath doing burpees within seconds. However, the community never let me feel down, and kept encouraging me. It would of been very easy to stop, but KOA has an atmosphere where you want to keep getting better, even when you are struggling... I really felt awful physically, but emotionally the support I got far outweighed it.. This pushed me, and others to keep going. I stayed with it, and It's amazing how 3 years later to see how far I've come. I've gone from not even knowing how to squat to squatting nearly 400lbs. I couldn't do a pullup, but now can grab the rings and pull off some muscle ups... Somehow I can even throw up over 150% of my bodyweight over my head... The program just works! If there is a negative, it's that this place has somehow created a magic atmosphere and unbelievable positive energy that makes you think you can do anything if you put a plan together and execute it.. The  confidence I gained from KOA made me believe that I could run the NYC Marathon, and a 70.3 Ironman Race... And somehow I did them both... If not for everything KOA has taught me, then I don't think any of these would of even been thoughts in my wildest dreams... The constant motivation to get better never ends no matter where you are... Right now,  I'm  signed up for a 140.6 Mile Ironman Race in July, and because of KOA I'm crazy enough to know I can do it... Join, and never look back! read more

All of the coaches at KOA are extremely knowledgeable, helpful, caring and motivating. They truly go above and beyond to ensure that we all do the best we possibly can and push ourselves to new limits. KOA is more than a place to workout. There is a great community atmosphere and friendly people who have become some of my best friends. Thank you to everyone at KOA (coaches and peers) for motivating me and making working out fun! read more

I called several times and emailed and never received a response. Guess they don't want new business. read more

I dropped in to Crossfit KOA with my fiancé and Josh, the coaches, and the athletes at this facility couldn't have been better. Although Crossfit prides itself on having welcoming, professional, small gyms, some boxes do not deliver on that expectation (especially for our-of-towners); however, the KOA community was extremely warm and welcoming. The facility has plenty of space and equipment- Eleiko and Pendalay barbells, bumper plates, boxes, rowers, etc. The bathrooms are large (and very clean!) and parking is in one of the public paid lots but very easy. I can't wait to drop in again the next time we're back in the area! read more

I've never been athletic...actually, I discovered exercise in my early 40's all due to KOA. I went to a class on a whim and was shocked. It's not fancy...but it's effective. I was exhausted with the warm up. Bear in mind that I was 30+ pounds overweight and previous exercise consisted of walking and elliptical. The coaches and KOA members could not have been more supportive. Everything is modifiable...everything! The coaches stop you if they see you need a change on a movement...they want you to push yourself, succeed and not get hurt in the process. The members are like a family...you want to go and see everyone work hard...the encouragement is unbelievable. This year I ran a half marathon with the support of my KOA family and am planning another one later in the year. I could not recommend this facility enough...they changed my life!! read more

I've been to numerous boxes but no place made me feel as welcome from the first day on as Crossfit KOA. From the owners to trainers to members, the overwhelming sense of community was apparent. Feeling welcome is important but programming, scheduling and knowledge of the coaches is even more vital. The main coaches, John & Josh, are extremely knowledgeable while doing a great job of balancing between being supportive/caring and pushing you to improve/exceed each and every day. I am a loyal 5amer now but when I have a day off there are numerous classes throughout the day and night I can attend and at least one class on each weekend day. The programming is varied and always keeps you working on different things, even things I hate doing :( Great gym, great people, super fun and it keeps me from getting too fat - thank you KOA!!!! read more

I am a 58 year old woman who spent years as a runner and doing traditional workouts at a local gym. While my workouts provided good exercise I felt like they were becoming repetitious and boring. I was looking for more of a challenge and decided to give Crossfit KOA in Cranford a try. My first trial workout was a shock. I was introduced to exercise movements I had never experienced. I thought I was in good shape but was exhausted after just seven minutes. I became hooked. The coaches at KOA are awesome. They have guided me through the unknown and motivated me to accomplish things I never thought I could. People of all ages, sizes, skill levels and backgrounds train at KOA. KOA provides a family feeling where everyone encourages and pushes each other. KOA definitely provided the challenge I was looking for. I am stronger than I have ever been. KOA has become an addiction, but a healthy one! read more

Not very friendly and was given a hard sell on some type of supplement program. I left after a 30 day trial groupon.

CrossFit KOA has sincerely been a game changer for me. I have ALWAYS hated exercising. I am naturally very muscular and stayed as far away from weight training as I possibly could for fear that I would bulk up instead of getting lean like I wanted to. I was also very intimidated by the gym and, more specifically, the lifting sections of my regular gym. However, Josh and his team of incredible coaches have completely turned around my viewpoint. I came in for a trial class terrified that I would embarrass or hurt myself. By the end of that class, I felt so confident that my coach and my peers had my back. Through my foundations training, I also learned the proper techniques for lifting, etc. so that I do not hurt myself. The coaches also continue to keep an eye out during the regular classes to ensure everyone is on their game. I feel motivated everyday to become the best version of myself and I keep coming back for more because of this wonderful atmosphere. The gym itself is always clean and has plenty of room for me to feel comfortable in my own space. They have a lot of class options and even open gym time so that I can make sure to fit my self-care into my schedule. The exercises are always different and keep my body guessing. There are also lots of opportunities for interesting activities like a Kettlebell Kitchen tasting, FaithRx, holiday challenges, weight loss/body fat % loss competitions and more. I can't wait to continue to see what CrossFit KOA has in store for me. read more
