My son is in the little warriors program. At first I was worried because there were so many children in a class, but class size doesn’t matter for these amazing instructors who teach not only martial arts techniques but also children’s leadership skills, confidence, as well as physical strength. Shortly after joining, my son’s behavior in school started improving by leaps and bounds. Now we are in the midst of covid19 and the instructors have done an AMAZING job of moving programs online through live and recorded classes. The additional fun events like the “kids night in” and challenges really make my son feel like part of a social community. This is one of the best organizations we have ever seen for children. I cannot give Pentagon MMA enough positive remarks. Well done and THANK YOU for everything you do to strengthen our kids bodies and minds. This is not just a class, but a community. Thank you.

I joined Pentagon MMA almost a three years ago. I watched my body transform into the best shape of my life. Who would have know that comes at the age of 35?! Well with Muay Thai, it does! This school has some of the best instructors in the game. Kru Vivek, Kru Chon, and all of the staff give this boutique gym a family feel, one that is active in the community just as they keep you active on the mats. When the pandemic hit, the gym immediately pivoted to online distance learning for the few months they were shut down. I have never seen a business take it on the chin so well (pun intended) and make this kind of a tremendous pivot. It must have cost them lots of money and certainly lots of work. But they did it, and it kept me sane during the worst of quarantine. When they reopened, they made sure people are training in a safe environment where social distancing is heavily implemented and online classes are still offered for those unable to come in. I highly recommend this gym. Anyone, regardless of age or gender or fitness level or experience should try a class out. Keep it up Pentagon MMA and thanks for getting me (and keeping me) in shape during these tough times!

Pentagon MMA is an absolutely fantastic gym! I’ve been a member of their Muay Thai program for over four years and I don’t know what I would do without it. When the gym closed because of COVID-19 they shifted effortlessly online, holding live classes almost every day and posting recorded classes on their website. In this way, they never lost the incredible community feeling that has always been present in the gym. Since they reopened recently, they quickly re-adapted once more, finding a way to hold in-person and online classes while complying with all the COVID-19 requirements for gyms. I feel completely comfortable taking their in-person classes. Even with the required modifications, the workouts as just as challenging as they were before. I have recommended Pentagon MMA to countless friends and family members. It doesn’t get any better than this gym!

I can honestly say that I’ve never learned so much so quickly. The instructors are experienced and really know how to bring your martial arts potential, whether your goals are just to get fit or your an experienced martial artist looking to compete, there’s a spot here for everyone and everyone gets better together. I personally take Muay Thai can measurably see my improvement in skill and fitness every time I go. All in all this place is awesome.

We enrolled our five-year old in Pentagon MMA's Little Warriors program. Our only regret is that we didn't enroll him earlier. Reluctant to participate and shy at first, he not only learned the fundamentals of jiu-jitsu and self-defense, but also developed self-confidence, self-respect, focus, and respect for others. Highly encouraged for all children.

This is my first ever martial arts gym that I ever attended and will probably be the only gym I ever go to from here on out. Staff is super friendly and the gym has some amazing coaches. I have only ever attended the BJJ classes but I'm sure their Muay Thai classes are just as excellent. Unfortunately due to the Covid pandemic I had to cancel my membership. However they are also offering live classes thru video chat I believe, which is awesome for those of you who want to learn martial arts thru the comfort of your home. Once this pandemic is over I will for sure be returning. Would give 6 stars if possible.

Best thing about Pentagon MMA is that time and time again they have proven that their relationship with the students is more than just a transaction/monthly payment .... they are super dedicated and provide individual attention whether in person ... or virtually! Which is why the standard of training is incredible! One of the best I have ever seen..... sorry covid-19, you cant get between me and Muay Thai ... thank you Kru Vivek Nakarmi for everything you do!

My daughter and I have been using the online classes and are so very grateful for their existence!! Still feel strange watching that first one with that old lady (me!) in it!!! Thanks Master Vivek and all the other staff for staying the course.

I wanted to thank you again for the online classes and everything you're doing! I haven't been able to take a live class but the replays are fantastic! we have a heavy bag up and try to use it with every class! thanks again! y'all are awesome! having the workouts and the videos to follow have helped my sanity and are keeping me positive!

I cannot say enough positive things about Pentagon MMA. I moved to VA without knowing anyone and I quickly made life long friends here. In addition to these connections, I learned not only Muay Thai, but the ART of Muay Thai. I cannot stress how rare this is. Pentagon MMA is not just a cardio kickboxing class. You will learn proper technique, the art of Muay Thai and its origins, and boost your self-confidence. Vivek was the best teacher I have ever had in Muay Thai, and I have yet to find a school that even comes close to PMMA now that I have moved north for work. Best Muay Thai school around!

I am a complete newbie when it comes to Muay Thai. I have grappled with some friends with jiujitsu and always wanted to get back into some sort of martial art but as a female, I always felt intimidated as usually these places are male-dominated. I did not have to worry about that here! The instructors have always been informative, patient, and kind. It must rub off onto the people to as they have been super nice as well. I'm glad I signed up! Will continue this until I move out of the area but I definitely have a better appreciation for Muay Thai now thanks to Pentagon MMA.

Awesome place. I love training here. Have been learning Muay Thai for over a year. The trainers are excellent and the community outstanding. The facility is always clean and all the staff is very friendly. I would recommend this gym to anyone: Beginners and advanced. Master Chon keeps the lessons interesting so that you will learn something new.

My son is in summer camp at Pentagon MMA in Arlington. It's fantastic -- he's really happy and they have a very organized and well-run program. In addition to martial arts, they take several field trips (and even had a back-up field trip set up for a rainy day), and do a lot of activities with character-building elements. When I picked him up a few minutes early at the end of his first day, he asked me if he could stay longer and keep playing with his new friends. I'm very impressed with the staff and coaches, and I definitely plan to sign him up again next summer.

My son went to Spring Camp here. We had not seen the facility before we dropped him off the first day so he was a bit nervous (as was I), but within minutes the welcoming staff made us feel comfortable and gave clear directions on how we could jump into the fun. When I picked him up that first afternoon, he said "Mom, you know what I liked about camp? EVERYTHING". He wanted to tell me about his day every day of camp, when I am normally prying it out of him. Huge hit and we will definitely be back.

Pentagon MMA is excellent!!! My 4-year-old son started with the aim of learning self-defence, but he has learnt so much more! His confidence, listening and responsiveness, and focus and concentration have all improved!!! Thanks Pentagon MMA.

My older kid started coming here a few months after I did (she's 4). It's been amazing - from the facility itself (clean, open spaces) to the staff (professional, welcoming). There is an air of humility and hard work that permeates and is contagious -- and you can see it stems from the leadership of owner Kru Vivek.

I cannot explain how much this has helped my four-year-old daughter. Your head would explode if you heard her shouting "yes sir" and "yes ma'am" around the house for chores. She has taken to the discipline very well and it's helped in her academics and in her social life, not to mention that she is learning to defend herself with some solid foundations.

Mike K

My kids studied at Pentagon MMA for several years each. Vivek and the other instructors taught them how to defend themselves, how to defuse tense situations, how to stick up for kids being bullied, how to conduct themselves with maturity and respect for others, and how to be mentally and physically tough. All of these lessons transferred to their lives outside of MMA. They are respectful, confident, and mature young people now. In addition to being proficient at MMA, the mental and physical rigor and determination they learned at Pentagon has been critical in one of them transitioning to collegiate athletics and the other on the way to doing so. The discipline and focus have also led to high GPAs and a drive to succeed. I can't recommend Pentagon MMA highly enough. It's been central to the successful development of my kids.

I’m new to learning Brazilian Jiu Jitsu, and I wanted to learn the art from a gym that would push me to be great but also accept me as part of a family/team. I’m happy to say that Pentagon MMA is just the place, where I have found both and more. I’m still very new to the sport and the gym but I feel confident that I will be training at the gym for a while even though I live a decent distance away. Pentagon MMA has exceptional customer service, great instructors, and welcoming members! I highly recommend this gym to new and experienced martial artist OSU!

I highly recommend Pentagon MMA. I've been taking the women's kickboxing classes since November. Staff members are warm, welcoming, and immediately made me feel comfortable. I love the instructors (Belinda and Patti are particularly fantastic) and the challenging and supportive environment. If you're on the fence, try a free class or two. I think you'll love it.

I’ve been coming here for several months and I love it. I started coming because I felt bored with my usual workouts. Kickboxing is like no other and will kick your butt. The gym is so welcoming and there are people of all fitness levels and ages. The classes are tough but manageable and I’m getting in the best shape of my life. Highly recommend.

Pentagon MMA has a range of different programs unlike many other gyms. It is wonderful for those who want to get fit and it's serious enough for those who want to fight. They have an amazing kids program as well

Amazing place. The staff is beyond friendly and create a truly welcoming environment. At no point do you feel like an outsider. The training is top notch. Master Chon is a true professional and makes sure you're learning step by step. Walking into Pentagon MMA has been one of the best decisions of my life.

Pentagon MMA is an excellent place to train! Vivek is an outstanding Muay Thai coach and their BJJ instructor, Sugi, is not only a BJJ Black belt but also a 2x Olympic Judoka. They are both friendly, welcoming, and great at what they do! If you are looking to start training in the Arlington area, this is definitely the place to go!

I have seen, from far away, how Pentagon MMA has grown from its beginnings to what it has become today. Vivek, the owner, introduced me to Muay Thai a few years ago and ever since I can’t seem to stop. Vivek showed me the basics to this beautiful art, back then he would tell me about his dream of opening a gym where he could share his knowledge with everyone else. After a few years, I finally went to visit his accomplished dream, his own gym, I was truly impressed. Pentagon MMA is a true Muay Thai school, where people are learning how to perfect their moves. I haven’t yet seen anyone who is there to show off or to put anyone down, everyone is focused and is there to learn. Thank you Vivek for Muay Thai is now part of my life. Thank you Kru Chon for never letting me quit!

I couldn't ask for a better place to train and call my second home! Pentagon MMA has hands down the best instructors. Master Chon and Master Vivek run an awesome Muay Thai program that keeps you fit and always learning more techniques. The gym has a "family vibe" atmosphere and everyone in the community is supportive of your fitness goals. I've already lost 20lbs thanks to PMMA's fight team, training, and encouragement. If you're looking to train with the best, you should definitely check out this gym.
