This gym is the best gym I have ever been to in my life so far! I was a complete noob and beginner…read moreto combat sports, specifically Muay Thai, and was shy at first trying to get myself just to walk through the door and ask a question! When I finally did, I was greeted with one of the most welcoming and friendly gym environments! Alex and Kyle have been very kind and helpful with answering my questions since the first day I walked in. The intro class was great and I didn't feel embarrassed at all for being a complete beginner- they teach the basics, have gear to borrow, and make the whole process trying it out very smooth and chill. Since then I have been going to the Muay Thai classes as much as I can. PRS has some of the best coaches, who are legends- so you absolutely get the bang for your buck! Coach Rob and Coach Six have been great coaches, and patient with me as a beginner. I asked for any and all tips, advice, and coaching during class and if they ever see me practicing outside of class, and they've helped me out a ton! I am very bad at hand eye coordination, but with patience and practice I get better every day. Coach Michael and Coach Shallon have been extremely helpful with learning sparring techniques on Wednesdays and more about the gym as well! All the coaches for Muay Thai are great and friendly! I recently been getting into some of the Boxing and jujitsu classes as well and had the same experience- passionate, motivating, and great coaches. Coach Mark teaches the Boxing class and has awesome boxing and strength and conditioning workouts, its very motivating and make me determined to get better. Coach Alex teaches Jujitsu, and has taught me a lot about the sport- its very technical, but he is a patient and motivating coach as well, and has given me great advice and made the sport more digestible to understand as a beginner! As I get more fit, Im hoping to add in more of these classes as well:)! Not only do the coaches help me improve as an athlete, but many of the fellow athletes are kind and welcoming to beginners as well- I usually ask for any tips or comment on my tech and get good helpful feedback. They have gloves, pads, shin guards and head gear available to borrow and use, and keep all their equipment sanitized and clean- including the training floor after each class. There are plenty of bags to train on, including some by the mirrors to watch your tech. They got everything you need in a gym, including an erg, assault bike, plenty of stationary bikes, and treadmills, dumbbells, kettle bells, benches, plates and bars, jump ropes, medicine balls, and rollers for recovery. Theres plenty of space to store your things and its safe to as well, as the locker area is in the back of the gym. They have clean mens and womens bathrooms and shower for after training. They got a really awesome ring and punching bags- basically combat sport heaven is PRS. The gym community is very friendly, welcoming, diverse, and accepting of all backgrounds. Ive met so many great friends so far :)! As a LGBTQ+ individual and woman, I feel safe and accepted at this gym :) 10/10 sanitation/cleanness 10/10 equipment 10/10 Coaching and trainers 10/10 environment, safety, and community 10/10 classes

Old-school boxing gym…read more I read about this place in the 3/23/25 SF Chronicle newspaper and went to buy a t-shirt for a friend who is a long-time boxing aficionado. Located in a short cul de sac next to the frontage road just east of highway 880. Parking was haphazard. Was greeted by Celeste King, who owns and operates the gym now. Inside it's like a scene out of a boxing movie, old school and serious business. There's an elevated ring where two boxers were sparring, guys skipping rope, hitting the heavy & speed bags. Hundreds of posters and photos adorn the walls and ceilings, including ones that proclaim this the home of Andre Ward! I bought a t-shirt with their logo for a very reasonable $20. When my buddy visits me again I'll bring him here, he'll luv it no doubt.

Great spot to compete out of if you're into that (Muay Khao style clinch-heavy gym), but if you're on the more hobbyist, fitness-focused end of the spectrum, Coach Jay runs his program to expertly accommodate that as well. He'll get you absolutely shredding looking as long as you consistently show up. Can't emphasize enough how clean this spot is, both hygenically and instructionally. Just take a one-day trail, walk into the restroom, and you'll be in awe at how clean it is. Then step onto the mat and learn from some very chill people how to defend yourself. Vibes are immaculate. Safe for LGBT folks and class sizes are just right. Shout out Coach Jay, one real dude.

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.

He doesn't just show up to run a class. He truly wants to see you improve, pushes you to your limits, and isn't afraid to call you out when you're not giving your best. I also attended the strength and conditioning classes with Coach Paul, and I highly recommend it. His sessions are well-structured, challenging, and designed to build real, functional strength that complements boxing training perfectly. On top of all that, the front staff is great -- always friendly, welcoming, and super helpful with any questions or scheduling needs. Whether you're just starting out or looking to level up your training, this gym offers everything you need with the right people to back it up.

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!

As someone new to CrossFit, I found James to be a great coach -- patient, attentive, and focused on proper form. He gave helpful adjustments and kept the class moving at a good pace. I'd definitely consider coming back once my wrist heals. I did have a small billing issue that took a little time to sort out, but James ultimately took care of it. It's clear they're a small business doing their best, and I appreciate that. I'm glad to support a local gym that offers solid coaching and a welcoming community.

Pacific Strength is truly something special…read more I am not a lifter and walked in feeling genuinely intimidated by a functional fitness gym environment. That fear disappeared almost immediately. The instructors (Jessica, Zach, Makenna, James, and others!) are kind, attentive, and incredibly good at meeting you exactly where you are -- no ego, no pressure, just thoughtful coaching and encouragement. James, the owner, is a wonderful human. He sets the tone for the entire space: supportive, inclusive, and deeply invested in people's progress and well-being. The community reflects that -- the patrons are welcoming and encouraging, and there's absolutely no judgment. I'm more of a yoga and Pilates person, but I knew I needed to incorporate strength training for long-term health. Since coming here, I've gotten noticeably stronger, improved my range of motion, developed better form, and -- most importantly -- gained confidence with weightlifting. No one cares that I lift a fraction of the weight others do. Everyone is focused on their own progress, and there's always a way to scale or modify. This is an ideal gym even if you're not looking to become an Olympic weightlifter but are looking to maintain muscle, protect bone density, move better, and feel strong -- especially for women who want functional strength without intimidation. Pacific Strength proves that strength training can be empowering, accessible, and genuinely enjoyable. I can't recommend it enough.
