I've been coming here on and off since May 2022, and I LOVE it! This is my first time joining a fitness club/attending classes (outside of 24 fitness) :} and I'm so glad I started at Koa (shout out Cedric!) Joining anything new can be intimidating, especially a fitness class. However, everyone, and I mean EVERYONE is SO nice and welcoming - Koa staff (morning and night), all the different coaches and other people attending the class. Anyone with any level of experience is welcome. You can ask anybody for tips and help, and they will patiently guide you! I usually join Boxing and Muay Thai. I have yet to join Yoga, and I'm trying Jiu-Jitsu for the first time ever tomorrow :) read more

We came in as potential clients for the youth classes and we were shocked how disorganized the classes were. There was no seemingly structure. I think there are too many kids with different status (beginner vs advanced) and age ranges 4-16. When they broke into drills there was an instructor showing the 6 (ish) year olds the drill and then walked over to the older kids with another instructor. I was baffled. How do you leave little ones to do a partnered hitting drill by themselves? There were 5-6 instructors but they seemed to talk amongst themselves and not demonstrate or monitor the kids. Sandy stated they have students completing their degrees, who need hours coaching. So basically, volunteers who don't care. I'll keep my money. They need to reevaluate their business model and hire dedicated coaches. read more

This gym is an absolute gem! The boxing and Muay Thai classes are top notch expert coaches, great technique drills, and good sparring that pushes you to improve every session. Clean facility, supportive vibe, and solid equipment. Highly recommend for anyone serious about striking arts! read more

There are many kick boxing gyms in the Bay Area that are willing to work with people on pricing for a day pass. The coach couldn't even offer us a reasonable fee. We were not asking to train for free just needed to meet us half way and were not willing to negotiate or consider the fact we could not pay $30 each person. It was 3 of us. 2 of my friends have only trained 2x in there life and we were not able to do sparring anyway. Pretty unfortunate and bad first impression. I even explained to him my cousin was just looking to get into a hobby after being incarcerated. Won't be coming back. read more

It's ridiculous to many machines broken for weeks and they don't fix it. ITs ducking dust and paper everywhere, I don't think they have any body to clean up plates everywhere, but they charge for the membership on time. Maybe just cancel my membership soon! read more

KOA Fitness Center has truly been a game changer for me. I joined after being diagnosed with diabetes, knowing I needed to take better care of my health. KOA has supported me every step of the way. From day one, I felt welcomed; not just by the staff, but by the members too. The sense of community here caught me off guard. The coaches are knowledgeable, approachable, and genuinely care about your progress, whether you're a beginner or experienced. The Weekend Boxing was a little hard for my skill level =p. I've tried everything from Muay Thai to to strength training, and I love that all classes are included in my membership; it keeps things fresh, convenient, and accessible. Each class has been filled with welcoming, encouraging people; and I've even made a few friends along the way. The facility is spacious AND clean. Keywords: friendly friendly + supportive. Last Tip, Try the YOGA classes Tuesday & Thursday! read more

Exceptionally clean gym with polite staff. I came in with my friend and they were so accommodating. Their memberships are all-inclusive so we get to take everything together, muay thai, boxing, yoga, etc. read more

Love this gym! Amazing coaches and the front staff are very welcoming and extremely friendly. If you are looking for a good gym to workout, and train or even to start your fitness journey, I highly recommend Koa. read more

Amazing gym! The atmosphere and community is great. I highly recommend the Strength & Conditioning classes. The energy brought by the coaches is engaging. Overall 10/10 love this place read more

I've been training with Anh for around 6 months and he is amazing. Anh is an incredible coach. He pushes you to your limit to make you better while providing positive encouragement. If you want to up your game he is the person to do it. Highly recommend. read more

I was a member here for about 5 years, the membership is definitely worth the price. You get a range of classes for one price, they include boxing, muay thai, bjj, crossfit, and weight training. The instructors all know what they're doing and are nice and supportive to all levels of fighters. The one star reviews here are not a representation of how this place really is, the owner does a good job to make everyone feel like family. There is closeness you get at this gym and its members than you would anywhere else. They have some of the most loyal members because the vibe here is welcoming. They also use to have a yearly bbq before covid which was super fun and awesome to have. They have multiple fighters that have been in real matches and performed very well. I definitely recommend coming here. read more

I used to utilize this facility a few years ago, so I decided to come in to the location to get information regarding rejoining. I ended up being greeting by Craig. I'm not sure if he was the supervisor or the owner however he was not very welcoming. Although he did answer most of my questions, he seemed very uninterested and rude as if he was rushing to get us out of the building. The guy was literally sitting in front of a computer in an empty gym and could've easily have answered all the questions in a more friendly manner instead of continuously telling me to check the website. Craig, you also need to update your discount policy regarding military personnel. Currently you're only offering discounts to active duty only and not veterans, which wouldn't make much sense since theirs not many active duty personnel in the area or will be able to make it to this location. On top of the lack of veteran discount which basically every gym I've signed up for over the years offers, they lack any type of incentives for signing up long term which also doesn't make sense. It's basically $160 a month done deal. There are far better and more affordable options out there instead of this place. AVOID!!! read more

Not only is Koa Fitness a great place to train (whether it be for Muay Thai, Brazilian Jiu Jitsu, Boxing, etc), it's an amazing community for people to thrive in. I've only been training here for a month and already I feel like I've found my home in gym form. The trainers are incredibly polite and well informed- it's obvious they know what they are doing and only want you to excel in whichever craft you decide to pursue. They also offer 2 class trial passes which is very convenient in the event that you want to give it a trial run. All in all, this gym is amazing- the community, trainers, environment and staff. Thank you Koa Fitness! read more

I've been coming into the Crossfit classes since July 2021. The crossfit coach Thomas is super personable and really takes the time to get to know your strengths and areas of growth and recommends the proper modifications or scaling for whatever the workout is that day. The crossfit area is in the back of the gym and there is a good amount of space dedicated to us, although most of the space is dedicated to the fighting sports. The owners have also invested a lot into the crossfit side of things with new equipment being purchased regularly. If you're thinking about starting crossfit or just want to workout in a class setting, you won't find a more welcoming coach an community than here! read more

Paid faithfully & on time every time for YEARS.. My cancelation was 3 days short of a 15 day notice and they charged me an extra month anyway. My daughter hasn't been going for months! They already got free money for months... so rude read more

I really have found a place that not only motivates me to go to the gym, but has helped me build confidence in myself and become an outlet for stress/anxiety. I first joined back in December. I honestly didn't want to try it since I was happy/content at 24. Once I got into the groove of the different classes that they had to offer, I knew I found my new forever gym home. Parking here isn't too bad. Sometimes it can get crowded, but overall, you should be able to find a spot in less than 5 minutes. Once inside, you're greeted by someone at reception, and will log in on an iPad. Ample classes! I personally take CQC (closed quarter combat), Barbell Club, and Muay Thai. They also offer BJJ, self-defense, strength and conditioning, and boxing. Programs are available for children AND adults. If you find yourself not being able to make it to class, they do allow for open gym usage, which is super great if you just want some alone time. Teachers are well-knowledgeable, respectful, and overall great coaches. Even though the gym is on the more expensive side (I pay $160/month on a student all access membership), IT IS TOTALLY WORTH IT! read more

Completely wasted my time coming here. Booked a free class online, to show up to the location and they have no record of the class I signed up for. And apparently it's now only offered on a weekday... when I initially scheduled the class it was on a SATURDAY! I work weekdays so I would never schedule a class during the weekday..they didn't even try to rectify the situation it was like "sorry bye!". Their website is clunky, not really user friendly so I'll be looking for another spot for Muay Thai in the Bay Area. Don't waste your time. read more

If you read nothing else in this review, you should come here and give this a try. :D And stay so I can live vicariously through you. It's an amazing place to learn. If I were not slaving my brains away on the opposite side of the country for most days out of the year, I would very much love to get a membership here. (I want to learn everything. ;_; ) Since the powers that be have made this pretty much impossible, I pester my brother about joining so that he can learn instead and teach me everything he absorbs. :] I purchased a Groupon for 5 classes here (either BJJ, Muay Thai or strength & conditioning) in October so that I'd have a place to work out at while I was home for what I believe to be my last winter break ever. My interactions with everyone here--on the phone or in person--have been great. Everyone I've met there has been super friendly and welcoming, which is always a definite plus when you know they can all beat the crap out of you. D: Strength & Conditioning: I decided to take this first (taught by Anthony!). In theory, it was to ease me back into the world of movement and exercise. (I'm horrendously out of shape due to the fact that I'd been stuffing my face with alarming amounts of food for the past 5 weeks.) With that in mind, I was pretty much gasping for breath within the first 20 minutes of the class. I haven't moved (by that, I mean "gone to the gym") in a pretty long time thanks to the never-ending study-guilt and poor life choices ("But Farrah, there's food to be had and you're also really tired!") I forced myself to push through though. The tire flips are my favorite. :D I was really, really flattered when Anthony asked me where I used to train, since I'd like to think that it means I don't completely suck at life despite the lack of movement. F: Train? Um, pretty much nowhere. A: Really? F: Well, unless you count the fact that I do powerlifting for fun? :O A: Ohh, that explains it. Your form is really good. Score! :D! Brazilian Jiu Jitsu: My experience in BJJ extends to random "Hey, we're actually both free next Wednesday! Can you help me level up my badassery!?" meet-ups. They've occurred once every couple weeks/months in the past 1.5 years, and my friend says I learn quickly and am improving by a lot (I always think he's just being nice, although I would really like to believe that I have the potential to be good if I could, y'know, remember the things I learned). I think what I'm best at, for better or worse, is hanging on like a barnacle. I did not manage to do all 5 classes this week because of holidays, family, prior obligations and the like, but the classes that I did get to go to were super fun and a great workout. As stated before, everyone I met there was super friendly, supportive and encouraging. The teacher was on vacation, but all the other students were very willing to teach/explain things to me. :] I know cost might be a deterrent to some since times are tough, but considering all the different classes they offer and the awesome environment and facilities you get to learn in, it's a really good deal. (This is coming from someone who's drowning in student loans. :O ) NOTE: I was a total fail and read the flier incorrectly. They're currently running a deal where, with a 12-month commitment, it's $99/month. (Usually, it's $149/month.) read more

Still the best place to go for all martial arts and fitness needs. Before the pandemic i was clocking in at around 215 lbs. Today i'm 192. The trainers are the best in the bay, the space is vast and ventilated so you always feel safe training there. Go check it out, right off the 880 stevenson exit. read more

I spent two weeks researching Muay Thai/BJJ/MMA gyms in the Bay Area and after trying out KOA's two day trial I was sold. My big reasons: ‣ As an adult that had no experience whatsoever in any kind of martial arts, I was able to jump right in and get the support and patience of not just the staff, but other gym goers as well. Everyone was so genuine and I immediately felt welcomed into a family. ‣ I definitely feel like I'm getting a workout because I'll be sweating hard (and I usually don't sweat that much so it's saying something). The coaches gave me a lot of one-on-one time, helped me a lot with the fundamentals, and have so much patience for a beginner like me. Which really reinforces my next point ‣ The staff are really friendly and make me feel safe/comfortable when I'm here. They treat everyone with respect and are always supportive no matter what. I feel very free and relaxed when it comes to trying out all their classes. I prefer to do muay thai but I like the BJJ people so much that I have been trying to incorporate those classes in too! ‣ I found a lot of other gyms were too focused on youth sports and didn't really have dedicated schedules for adults who want to train. They have an amazing schedule that's flexible to fit around my busy weekdays and weekends. A lot of the parents who enroll their children here are also train here too! ‣ I used to go to regular gyms like 24HR but I felt like I wasn't accomplishing anything/getting help since it was like the Lord of the Flies in there. Personal trainers/certain classes were also an extra fee on top of my gym dues. KOA's pricing model is a great amount of value for the amount of service and interaction I get. ‣ The facility itself is clean, has a lot of open space, and great equipment. They have bags of all sizes, an MMA cage, and a boxing ring. They provide lockers and cubbies for belongings; which I totally feel comfortable leaving my stuff in (phone/wallet/keys in a duffel). This didn't seem big to me at the time but they have a water fountain and it has nice cold water+can refill bottles. ‣ Location wise, there's ample parking space and it's right off I-880. There's lots of things around the area (New Park Mall, cafes & restaurants, Pacific Commons is 3-4 minutes away); so if you have errands to run or you want to do something after, there's some great stops. read more

Amazing martial arts training and coaching. My home away from home for almost 5 years. Definitely take an authentic Muay Thai class from Coach Narupol or Enn, and BJJ from Professor Mauricio. The conditioning and boxing classes are great as well. If you're really lucky, you may get a class with the epic Daniel Kim. I still train here int, even though I live almost an hour away. Love and respect to all my coaches and training partners. Check out KOA ASAP! Cheers, Chris read more

BIGGEST MEMBERSHIP SCAMS! Do Not Waste your time or money at Koa fitness!! Their managers are unprofessional, unresponsive, and scam people in very expensive memberships by being dishonest, lying, and changing their words AFTER you have committed to a LONG TERM MEMBERSHIP contracts. We are extremely unhappy with what they have locked us into, even though they agree that they had an employee who was giving false information about how their membership worked. There is only 1-2 good coaches, but it's worth the months and months of back and forth about being scammed into the long term contract with no resolution. We have lost hundreds of $$$$ here. read more

I originally came to Koa Newark because the doctor said I needed to lower my blood pressure or take pills for the rest of my life. That was about three years ago (I'm now 46 years old), and since then I've lost 35lbs. (down from 225lbs.) almost exclusively training with Naruepol in Muay Thai. The M, W, F afternoon classes are my favorite because the classes are small, and I am able to ask Naruepol many questions about technique that are virtually impossible to ask during his evening classes. As a result, not only have I gotten stronger physically and become more fit cardiovascularly, but my technique has gotten better very quickly because of all the personal time I get during the afternoon classes. Since Muay Thai is as much an art as a combat form, it takes a while to develop striking techniques which are not only effective but also look good. However once developed, I don't see how anyone cannot but appreciate Muay Thai for both its viciousness and beauty. Koa is blessed to have championship-level native Thai fighters actively teaching their Muay Thai classes! The Koa staff has always been great, and the equipment and pads - though well used - are fairly clean. Three of my four sons are in the kids' Muay Thai program, and two of them participate in boxing and jiu jitsu as well. I appreciate that all classes for adults and kids are available with one membership price, and I especially appreciate that many of the instructors build on their knowledge and experience by currently competing in local and international tournaments. Looking forward to many more years of developing my technique at such a great place! -Jerome H. read more

Never say never. I have been active all my life but I have never been a get up early and go exercise person. I also was out of commission for 5 years after the birth of my son, now 6 years old, and my twins, now 4 years old. The labor and delivery of the twins was quite traumatic, leaving both twins in the NICU, and I was hospitalized for two weeks due to complications. After that, it was survival mode and exercise was the last thing on my mind. Finally in December 2019, I knew I needed something to uplift me, and so I began trying out different exercise spots, not easy during the pandemic! Finally on April 5, 2021, I walked into KOA and found CrossFit and Coach Thomas Wu. The very first day I met Coach Thomas, I knew instantaneously that he was going to be a great coach. By the week's end, he exceeded my expectations. He gives positive reinforcement to every single student in his classes, and as needed provides help and extra support. Every morning he is up at 5AM to coach his one of many classes throughout the day. Not a day goes by where he does not come to class without a smile and an aura that illuminates positivity. He is always encouraging and supportive no matter what level his students are at or how long of a day he has had. He is an exemplary model of what we want every instructor to be like. His heart is always in the right place, and the patience he has to work with all students, but especially those who need extra support, is admirable and inspiring. His authenticity shines through, and when in his classes, every student is supported and checked in on. I never thought I would ever join CrossFit, and now I can't imagine ever going without it. I do my best to come to Coach Thomas' 6AM class Monday - Friday because after every single class, without fail, having the CrossFit work out and an instructor like Coach Thomas guiding and supporting you, I am able to start my mornings feeling amazing, positive, uplifted, energized, and ready for what the day brings. The 9AM Saturday classes are a great way to start your weekend and are always fun when we partner up! CrossFit is not just what I do now; CrossFit is a part of my life. Never say never. read more

10/1 still waiting on my refund 9/12/18 still waiting for refund, have not recieved any response to emails being sent ​ 9/5/18 still waiting on my 220.00 refund I was so excited when I found this gym! The trainers are amazing and help you along the way and they also have a military discount however, the business side is horrible and extremely unprofessional! I joined in April and was called away for overseas service for a few months starting in late May . I went in to cancel and the blonde Asian guy couldn't find the form so he made me hand write the cancellation form assuring everything would be fine I left for my mission. Now anyone in the military knows how stressful it is to just up and go, well it's even worse when you see that your being charged after you've cancelled . Not only did they charge me a $20.00 cancellation fee at the end of May (military is monthly and when I signed up it was stated there was no cancellation fee) but they also charged me for July and August. After the cancellation form was sent in for the second time. And calling in would cost me a fortune, so I'm relying on email traffic. I even had a friend go in for me and said they couldn't help it at all . I was really hoping to continue with this gym when I got back home but this just leaves me with a really bad taste of how this business is conducted. read more

Great fitness programming for all levels of ability and experience. The CrossFit coaches aim at helping each individual succeed at their fitness goals and the community is both welcoming and supportive. read more

TLDR: This isn't just a fighting gym, this is a community with great people who will treat you like family. Don't be afraid, I was intimidated my first day but now I'm damn right hooked! (Get it??) Brace yourselves, it's long but it's worth it. When people think of a fight gym, they probably imagine a bunch of scary, serious, intimidating dudes that just care about knocking you out. Well, they can definitely do that, but they wouldn't**. That's not what it's all about. You don't have to be an angry person to train, you don't have to be in the best shape of your life (that's the point of gyms), and you don't have to be a seasoned fighter to workout at a fight gym! I mean look at me, I'm a rock climber and I do yoga... I'm as peaceful and tree-huggin' as they can get, and I love it here! I've never taken any type of martial arts before ever in my life. Ever. I've always wanted to but my parents thought it was too masculine. But they're wrong! Martial arts is like a dance where balance, technique, and coordination are needed. Strength alone won't get you very far without the rest. And if you're lacking in any of the skills above, Koa is a great place to learn!!! Classes they offer: + Muay Thai + Boxing + Kickboxing + Brazillian Jiu Jitsu + Wrestling + Judo + Strength & Conditioning + Yoga + Dutch Kickboxing + Self-Defense There are also open-gym hours and sparring classes. Every instructor and fellow member that I've met here has been very friendly and helpful. It's a great environment for the inexperienced noobs (like myself) and those with a wide range of experience looking to improve. It's also a killer workout that can really build your self-confidence. Especially good for both adults and younger kids. They have youth programs for kids to stay active, build good discipline, and gain high self-esteem. I've mostly been doing Muay Thai, because that's where most start (been here for a month). I love it! Intro class-- you'll probably work with Jake or Rolando, and they're both great instructors that will patiently help you despite your clumsiness (fell on my a#$ first day). After you take your intro classes you'll move into fundamentals or you're free to roam to other classes outside of Muay Thai. I personally really enjoy Muay Thai; the kicking is a really fun component and adds to the full body work out. I've only had the pleasure of taking John's and Daniel's Muay Thai class. Both are excellent mentors with great personalities that keep the class exciting and entertaining. They also really focus on technique which will build you a good foundation. I've met some of the other instructors and heard good things about others. Definitely interested in taking more no-gi BJJ and self-defense class with Mauricio. Good techniques to know especially for ladies who don't want to feel vulnerable in bad unexpected situations. I've also heard that Germaine (she fights in UFC!) teaches a great class. Legit! Complaints: + Pricing... Maybe... This is probably the biggest turn-away for most people who aren't familiar with martial arts training gyms. BUT lez be honest, look how many different classes they offer... Let me break it down for you. I know for a fact if you took yoga at a studio, membership is ~$50/month at the very least. Granted that the yoga at Koa isn't the same as a studio designed for it, but here you get yoga + a ton of other work out classes. I've never done any martial arts before, but I'm sure Muay Thai alone would cost the same or maybe even more than yoga, and this gym is designed for it. So at Koa it's like you're getting a bunch of $50 memberships for one, much more affordable, package. And this is not a basic gym like 24, here there are actual live people training you actively, which, in my opinion, is so much more fun and effective than staring at a workout chart on the wall. A YouTube video cannot tell you how you're doing and where you need to improve on. So when you think about it the price is actually quite reasonable. And if you're only looking to do one type of class, they may be willing to work it out with you. Just talk to them, all the workers are very friendly! WORTH IT. **You won't get knocked out but you will definitely get your a#$ kicked from the fun and super rewarding workouts! You'll leave class feeling good every time. read more

Koa is an excellent place to train! They offer multiple disciplines with the most experienced instructors, along with a wide range of class times. The gym is immaculate with plenty of equipment and training partners. I've been training here for over a year so far and am glad to have found this place. I mostly train Brazilian jiu-jitsu with Mauricio, but every now and then I train Muay Thai, MMA, and barbell club; these are all great classes and the instructors are outstanding. But don't forget to check out all the other classes they offer! Whether you're looking for a place to have your kids train or for yourself, you won't regret coming here! read more

This place is awesome! period. I am here 4 times a week and 2 of my kids are here as well for their BJJ & muay thai training. After coming here for a few weeks, I can really feel my body condition is greatly improved and as well as my fighting skill ( eventhough I don't think I will ever fight anyone). read more

Top quality martial arts and fitness training. The facility is large, conveniently located, is open 6 days a week, and has a ton of equipment. The space is large enough to have 4 classes running at once and have room left over for solo training. Locker rooms and a small equipment shop, ring, cage, mats, and all sorts of punching bags. But the best feature is the talent of the instructors. Each has that hard to find sometimes combination of high level martial skill (professional fighters) and being genuinely good people. Their martial lineage is impressive, either the students of legends or epic in their own right. In addition to the regular staff, the gym also will bring in, no exaggeration, world class talent, fighters that define a style, for seminars. I would encourage those thinking about joining to look up the instructors fights online - they are the real deal. Feel confident in that you are learning from an expert. For those new to martial arts or the casual participant, you will get definitely get in shape. It is hard work, but there is probably few other activities that could match the cardiovascular benefits of Thai Boxing or the whole body isometric strength developed in Brazilian Jiu-Jitsu. A big thing now is adventure runs - those are easy after learning to sweep a 200 lb man or doing a few hundred round house kicks. Not to mention the mental benefits of stress reduction. Nothing helps after a hard day than walloping a heavy bag! Be persistent and positive and you will get better. It is also important for new members to know this is not a knucklehead gym - it is a family environment. In fact, some of the most amazing competitors in the gym are kids. There are potlucks, fight nights, etc. For those who want to be fighters and competitors, all those resources are there. But the benefits of those resources i.e. the quality of teaching and an environment of high standards helps everyone. For those already training, it is, at least in my opinion, a little slice of heaven. I come in, see my friends, and basically have a ton of fun. Here was my training schedule this week: 3 hours dutch kickboxing, 2 hours jiu-jitsu w uniform, 1 hour no gi jiu-jitsu, 1 hour thai boxing, 1 hour traditional boxing. I haven't made it to strength & conditioning lately but those classes are great as well, all about functional strength and plyometrics. read more

I have been wanting to get back in the gym and get back into shape. Just honestly didn't have the motivation or drive to do it. My good friend that is a regular at KOA Fitness talked me into it by getting a week guest pass. I have done Crossfit for about a year and loved every minute of it until i moved back to the bay area and wanted to find something new. i went into KOA today really nervous and kinda intimidated. I was welcomed in by Natasha. So was so nice and welcoming. Made me feel right at home. Gave me a quick tour of the facility and i was really impressed. Every member was really nice that i came across. I started off with the Intro in Muay Thai. i loved every minute of it. It tested me a lot. The instructors were top notch. I learned so much and was very happy with my first class. I will be finishing every day with this one week guest pass and will be definitely becoming a member. read more

This place has real-deal, legit instructors and amazing facilities. Everything you could want for martial arts and fitness. Super stoked I found them. read more

Just bought a membership and it's going great so far! They have great coaches and classes you can take in order to improve on your preferred skills. read more

Really cool place to train. Very friendly and very inclusive staff. Going to a place like this can be really intimidating for beginners but they do a really good job and helping people feel comfortable. The facility is HUGE so you'll never be cramped for space to train. Instructors are quality and good role models for kids (and adults as well). I'll never forget one conversation I heard between a kid and the BBJ instructor: I: "Why don't you take BJJ?" K (with a smile): "I like punching and kicking better!" I: "Aww well that's ok. I still like you no matter what!" The significance and quality of this conversation is beyond words. It may be a bit pricey, but if you account for the size of the place and the quality of instructors, it's a pretty reasonable price to pay for full access. My only criticism is that they only have two weekday morning classes and so I wasn't able to continue my membership :( read more

Recently moved back to the Bay Area from Los Angeles and wanted to get back in shape. I've been a long-term 24hour Fitness member, but the classes and venue just doesn't do the trick anymore. Nothing there inspired me. A friend recommended KOA Fitness and I've been attending their classes for almost 3 weeks. What keeps me invested in this place is the vibe....all age groups can be found here and the instructors keep classes on-point and challenging. Exactly what I was looking for. KOA fitness has several programs available, but I like the Strength and Conditioning classes + Muay Thai workouts. I'm drenched after every class and happy that I'm inspired once again to get fit. I highly recommend that you give this place a try. read more

This is literally my favorite place in the Fremont area. Staff is super friendly, other members are super nice. I came in as a know-nothing beginner, feeling weird and self conscious, and very quickly felt at ease. Before coming here, I didn't really understand when people said things like "gym family". Koa has taught me the meaning of that. read more

I've always been interested in a MMA style gym and there we're 2 major criteria that was very important: 1)Credibility & 2) Proximity. In my research, a college friend initially referred me to, at the time, Fairtex Newark. Since then, it has changed the name but the credibility and proximity remains the same. Let me tell you something. So far I've been going to the Gi BJJ and Muy Thai classes that they have. The fellow classmates and practitioners are some of the most supportive and competitive lot out there! Not to mention, the success of the students that Koa have produced! Everyone, from front desk to instructors, are so helpful. Bar none, one of the best decisions I've made so far. So glad to be a part of this family! read more

I have been going to Koa for about six months now, and I have to say I've loved every minute of it. Koa itself is very family-oriented and everyone is very helpful and supportive! I mainly joined here to get in better shape, because I wasn't really motivated to go to a normal gym anymore. I had never taken Muay Thai or boxing before. Even though I wasn't intending to get into sparring originally and wanted to go here more for just the workout, I have really loved Muay Thai and started doing the intro sparring class recently. During my time here, I have done Muay Thai and boxing. I enjoy Muay Thai more because it incorporates kicks, knees, and elbows, and just gives me a better workout all around. Daniel is the head Muay Thai trainer and his classes are a lot of fun. He uses a lot of interesting analogies when trying to explain technique and will always make you laugh. I have also taken classes with Lawrence, John, and Jake. I've really found it helpful to train with a variety of trainers, as they each have something to offer and can teach you something new. As for boxing, I have trained with Joe and Johnny. Both are very great and approachable people, with Johnny teaching the majority of the boxing classes. Johnny has been very helpful in every way imaginable. He's a great resource for boxing and nutrition, but also knows Muay Thai too. The gym is very big and I really appreciate the open gym hours. It's definitely hard work, but in my opinion is the most enjoyable and fun workout you can get. I have made some great friends so far and I'm sure I'll continue to meet even more great people. I can't recommend this place enough! read more
