They make it easy to go to a class as you don't have to sign up for a class prior to attending. You can just show up and they can accommodate you. My choose this gym because it convenient from my work and I can walk here after work. The only thing is that they make you purchase their shirt as part of their "uniform" policy if you go and are there for their Groupon. Shirts are $13 each which is not bad, but just beware and know this beforehand.

My girlfriends and I have been talking about getting together for a work out class for the past…read morecouple of months. When one of them found a Groupon for Empower: 5 group kickboxing classes for $19 (according to Groupon, originally $200), we decided to go for it. Our first class was on Wednesday, August 10th at 5:30pm. Johnny taught our class and he was awesome! Would make sure our technique was correct without making us feel like we were doing it completely wrong. Great in a class atmosphere if you get a little shy in group classes. We started off with jumping jacks as part of our warm up. Then we paired up and he taught us boxing combos. We would take turns punching and blocking/receiving. Great way to get out aggression. Most of the class was spend doing this. Then we went into their version of burpees, running in place, and some kind of crab/bear/spider crawl. When I was giving up during my crawl, Johnny kept cheering me on. We ended with crunches (which luckily for me, weren't too bad) and of course high fives to finish up the class. This isn't in the fine print for the Groupon, but it's only valid for their Monday or Wednesday class at 5:30pm, so keep that in mind before purchasing. For those who get off at 5:30pm or later, I wouldn't suggest getting this as you can't apply it to any other classes. Great first class. I haven't worked out in over a year, so it was nice breaking a sweat and punching out some pented frustration. Looking forward to my second class!

It can be scary being so new - I've…read moretried many gyms in the city and this was the first as a beginner I felt like I learned the most and retained the most. This was because of a combo of: 1. Clear visuals about what the different positions are 2. Moves that are outlined - you try the move, and then repeat it over and over again in speed/resistance 3. Then you have the opportunity to try it in sparring, which lets you really remember it! Definitely recommend and will be back - folks were super nice and welcoming!

Bay Jiu Jitsu is, by far, the best jiu jitsu gym I've ever trained at. I learned more in the nine…read moremonths I spent with them than I had in the previous five years, training elsewhere. They've ruined other gyms for me. Since leaving SF, I've traveled around CA, but haven't been able to find any gyms of a similar quality. Bay Jiu Jitsu is a special community with a level of elite instruction that's genuinely hard to find elsewhere, especially one that's welcoming literally to anyone, beginner or otherwise. Very few BJJ gyms offer any instruction in takedowns-be it wrestling or judo. A huge amount of gyms train nearly entirely on their butts or from their knees. Every instructor at Bay knows high-level takedowns and defense. We all grapple standing and are training takedowns constantly. The instructors here are incredible. All of them compete and their records in tournaments, to my knowledge, is excellent. Bay Jiu Jitsu is also the only gym I've ever trained at that constantly surveys the class for questions. Unlike the general, "Any questions?" at the end of a complex technique, they literally go around the room asking "what questions do you have?" It's such a simple thing, but very indicative that the gym is just operating at a much different level. The instructors actually help you to improve your game and learn the sport. You're not just mindlessly doing moves out of context that you may never use. Here, we work techniques and positions, and map out how to see them, what successful principles for passing open guard are, for example. So, you're constantly learning in a deeper and more meaningful way. Rather than an individual technique, you're learning how to think for yourself, how to figure out large-scale, applicable, perspectives/rules to operate under when faced with fundamental positions of the sport. All the instructors are talented and can actually teach. When they break down ankle locks, it's not just showing you one version of the submission three times and having everybody go and drill it incorrectly. The instructors will break things down, incrementally, and in-detail. Then we regularly attempt it with coaches going around the room, making adjustments, and then doing additional demonstrations and instructions. I don't think they ever just go through the motions with moves here. Everything we do has a point or reason to it. Bay Jiu Jitsu is the only gym I've been to (and this is dope) but it's the only gym where instructors ask individuals from the class, what do you want to work on? What's something you're struggling with or curious about? And we'll actually do it. Instructors here give a damn about you as a person. They track your success, watch you during sparring, and hold you accountable to reach your potential with feedback, advice, and encouragement. They have no uniform requirement. You're not forced to buy a gym rash guard or spend hundreds of dollars on their gis. They don't charge you for promotions. They teach you how to actually train smart. So many gyms don't do this and it's ridiculous, but here, they teach you how to avoid preventable knee injuries during takedowns/positions, how to fall correctly, etc. When there's sparring, there's pretty much always a person walking around, keeping individuals from falling into a teammate-blowing out their ACL or kicking them in the head needlessly. I could ramble on for ages about the gym. You'll train with loads of rad, high-level people here. Nobody has an ego. We're all willing to help out. You don't deal with people cranking your jaw to get a submission. Everybody's cool and will train hard, at times, but in a safe way. The gym does movie nights, goes out to bars, goes dancing, and has bonfires throughout the year too. If you're looking for it, you can make friends. I love the gym and the people here. If you have the chance to train at Bay Jiu Jitsu, you absolutely must.

You have people from all walks of life and different ages training together, and after spending some time here, you quickly realize how much knowledge and experience is in the room. Joel and the team focus on practical, real-world self-defense. The training is challenging, welcoming, and very different from a lot of martial arts schools that focus more on looking impressive than being effective. What really impressed me was seeing how skilled everyone is. There are a lot of experienced people training here, and it's a reminder that experience, technique, and good instruction matter far more than appearances. If you're thinking about learning self-defense, come visit, watch a class, and talk to the people here. You'll quickly see why so many students stay for years. Highly recommend. These guys are the real deal.

Before working with RJ, I felt intimidated by strength training, especially in a gym that often…read morefelt like a male-dominated space. Despite being an active person (practicing yoga, pilates, dance, biking, climbing) I had never properly learned how to lift. I tried group strength classes at various studios, including Equinox, but I was never sure if my form was correct or if I was targeting the right muscles. Movements like squats, bench presses, deadlifts, pull-ups, and hip thrusts all felt unfamiliar. RJ completely changed that. He made strength training approachable by breaking down techniques in a way that made sense and reshaped how I thought about training and eating. Growing up I was told women should focus on cardio and "toning" rather than lifting heavy, and because of that I never understood the benefits of progressive overload or proper fueling. RJ helped me unlearn those outdated ideas and showed me that lifting heavy wouldn't make me bulky--it would make me stronger, more capable, and help me achieve the physique I actually wanted. He gave me the confidence to lift heavier and push toward my goals (especially glute growth) and I loved seeing my progress! I also went from zero pull-ups to three in a row. The physical gains were exciting, but the biggest transformation was in my mindset. Now, I walk into the gym knowing exactly what to do. If you want a trainer who truly knows their stuff and will help you feel stronger and confident in the gym, RJ is the one!

I cannot recommend training with RJ enough!! I've been training with RJ and my best friend since…read morethe beginning of the Pandemic (first virtually and now in person) and it has been the absolute highlight of my fitness journey. When I first started I had absolutely 0 experience weight lifting or even going to the gym for anything other than cardio but training with RJ has helped me fall in love with weight training. In a few years I went from using my flip flop for Turkish Get Ups to regularly hip thrusting 205lbs, PRing deadlifts at 205lbs, and 185lbs in squats!! (It would have been a shorter journey without Pandemic restrictions, but I'm still very excited to only get stronger from here ) RJ is such an incredibly well rounded and informed physical trainer that I've never felt anything but 100% confident in every exercise, he really focuses on form and injury prevention and helps you think about your body and it's positioning in ways I've never given much mind to, he really makes sense of physical training in a way I've never experienced before! He's also well versed in mobility and stretching which was really important when recovering from grade II ankle sprain last summer. I absolutely adore RJ as a trainer and now friend, he's such a wonderful person to spend time with that I come out of every session with him rejuvenated and confident, if you're looking for a trainer please do yourself a favor and book a session with RJ ASAP!! If I could I'd give him 500 stars/5!

Like his father before him, Ralston puts a lot of emphasis on the solid fundamentals of jiu jitsu to ensure that no matter your belt level, you always have a very strong core foundation. And like his brother Clark, Ralston has some really cool tricks up his sleeve too, such as a solid armbar clinic similar to his brother's omoplata series. Before every class, we always have a 20-30 minute warmup that consists of the usual drills plus a good chunk of yoga stretches, which I've come to value as it not only helps my game, but also my old age lol
