I have been taking Muay Thai class with coach Matheus and I was surprised at how great he is at teaching. I've learned so much that was never explored at my old gym.

Two great coaches in their disciplines that one can learn a lot from.

It has definitely been a life changing experience for me, and I hope to continue to journey. Thanks to all the coaches and students.

They create such a great learning environment for kids. The instructors teach excellent techniques in a way that is engaging, supportive, and age-appropriate, while also maintaining high standards. The school does a wonderful job of making it both safe and fun, and it is filled with so many great kids. The owners are clearly highly invested in making it a great school, and that really shows in every aspect of the experience. The space is always clean, it is well priced, and it truly feels like a worthwhile investment in our children's self-discipline, self-defense, and confidence. We are so grateful to have found Old School Martial Arts and would highly recommend it to any family looking for a positive, supportive, and empowering place for their kids.

They understand the importance of fundamentals that so often get overlooked at other gyms. This place has helped me a lot in so many ways, even during one of the most challenging times in my life.

I've trained at quite a few Muay Thai gyms over the years. Like a lot of people who move around,…read moreI've bounced from city to city and tried different spots. Most of them were solid. Good people, good workouts. But Jay's Training Grounds was the first place where things actually clicked for me. What stood out immediately was the way Coach Jay teaches. Instead of just drilling combinations, he breaks down the fundamentals and the reason behind every movement. Footwork, balance, timing, defense, how punches connect with kicks, when to check, when to counter. You start to understand the system instead of just memorizing techniques. That made a huge difference in how fast I improved. The atmosphere is also very genuine. No ego, no intimidation. Just people who want to train hard and get better. Beginners get clear guidance, and more experienced fighters still get technical details that sharpen their game. It feels like an authentic Muay Thai training environment, not a cardio kickboxing class. If you're in the Bay Area and looking for a place to train seriously while still feeling welcome, Jay's Training Grounds is worth checking out. Drop in for a class, talk to the coaches, and see it for yourself. You'll know pretty quickly why so many people stick around.

My Muay Thai journey started back in 2014, and from 2014-2018 I was fully committed to training…read moreuntil life hit me with school, work, and relationships that forced me to step away. During that time, I gained a lot of weight and felt like I lost a big part of myself. When I tried to come back, I found that the gym where I originally started had closed due to rising rent costs. I checked out a few gyms in Oakland, but none of them had that same community vibe where people truly enjoyed Muay Thai for the art and what it represents, I didn't feel welcomed Honestly, I felt lost and thought I'd never find that feeling again. I even considered driving far just to train because I missed Muay Thai so much. That all changed when I came across Coach Jay's bio and saw that he had trained under the same coaches I had when I first started. I looked at the photos, saw the location, and instantly felt the same vibe I'd been searching for. From day one, Coach Jay was welcoming, helped me get my technique back, and I immediately felt the support from the entire team. Since rejoining, I've gone from 260lbs to 210lbs, building muscle along the way thanks to the strength and conditioning classes (something I never had access to before). On top of that, I've been training in boxing, improving and learning a lot, while of course continuing with Muay Thai. I've even competed in a PKB and plan to keep competing in the near future. For me, Muay Thai and boxing here have not only helped me get in shape but also pushed me to grow mentally, physically, and spiritually. The training is tough but motivating, and the team always makes you feel supported like family. Everyone trains hard, but there's also real camaraderie and respect. This gym has given me opportunities to challenge myself in ways I never imagined, from sharpening my technique to stepping into the ring. It's more than just a gym, it's a community that keeps you accountable and pushes you to become the best version of yourself. I'm incredibly grateful to Coach Jay and the gym for helping me return to what I love and for improving my health. If you're serious about training or even just curious to try something new, I can't recommend Jay's Training Grounds enough. - Manny

Fantastic gym! Owner and Coach Ignacio is a Muaythai champion with lots of experience training…read morestudents. I've been coming here ever since they opened. KO1 Roundhouse uses a combination of Muay Thai techniques, cardio, circuit, weights, and strength training. You get a little bit of everything. The gym is setup where it's super convenient to drop in anytime you want during their opening hours. I love that I don't have a set time I need to be there because my work schedule fluctuates. Once you arrive, you start in the first round with jump rope to warm up. You then progress to some weights, and then get to box on the bags. Every day the workout changes so you aren't doing the same thing over and over. You get a personal trainer to guide you through each exercise and they will also hold pads for you for an extra workout. You can finish the training in 33 minutes or even stay longer. Their hours of operation are also really generous and I find I can always find a time slot within their opening hours to drop in. The facility is brand new and super clean. The staff cleans after each round so I feel I don't have to worry about someone else's sweat on the bags. The equipment is high quality and brand name. Cool gear too for purchase with shirts, sweatshirts, and boxing gloves. I'd highly recommend you give KO1 a try, they are great for all levels. New members can try a class for free before committing. Monthly membership fees are affordable and so worth it! P.S. They also do Muay Thai classes that you need to preschedule in advance but I haven't had time to check it out yet.

He was very understanding of my situation and helped ease me in, providing a very safe training environment and allowing me to go at my own pace. The attention to safe training is always priority for Chris. After a time I was even able to return to training BJJ. The level of teaching is high. the head coach (Chris) is very experienced, as are assistant coaches who are active fighter. They regularly bring in world class veteran Thai fighters for seminars. The gym is very welcoming to newcomers and all types of people. It is always clean and the mats are disinfected multiply times a day and always before BJJ class which I appreciate. Overall I think this gym is great place to learn and train Muay Thai and BJJ for self defense and enjoyment. It is more of a community vibe than a hardcore competition gym, although there are a number of active fighters who train there so if you want to take it more seriously you can.
