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

Feels like just yesterday that I was scrolling through Yelp looking at workout studio reviews! I had never boxed before 9round, and I love it! It feels so great to just punch a bag after a stressful day at work. You feel so powerful! I also love the way that the workouts are structured. I can just pop in at any time and be in and out in 30 mins. I don't need to think about what moves to do for the day. And I always leave super sweaty and accomplished. What really stands out to me about the 9round in Emeryville in particular is the owner Charise! I knew when I was first searching for workout classes that I wanted a badass woman trainer and Charise is just that! She is amazing - super friendly and motivating! She is great at demoing different moves for noobs like me who can never remember the names of different moves. She also takes the time to chat with and get to know everyone!
