This location is owned by the same owners as GB Upland. If your goal is just to do jiu-jitsu for…read morefitness, this school may work fine. The main issue is the curriculum. It's very basic, standardized, and repeated year-round. This appears intentional. Regular classes teach only the minimum, while techniques outside the posted curriculum are pushed into paid private lessons. Because of this, most students are trained as hobbyists. Extra instruction or advanced opportunities often depend on personal relationships rather than a structured development path. The curriculum is designed for retention, not depth, and this model is consistent across Gracie Barra schools. The gap becomes clear when students compete or train outside the Gracie Barra environment. While internal GB tournaments create an even playing field, they can give a false sense of progress. When students compete outside of GB or train at another academy against the same rank the difference in technical depth, adaptability, and exposure is often very noticeable. Even the instructors don't train the same curriculum as regular students, which speaks to how limited it is. Compared to other academies that teach more as part of regular training (without extra fees), this approach leaves students less prepared overall.

*BUYER BEWARE* be ready to pay double if you cancel!!!…read more You have to remember one thing, even though this is about your "kids" this is really a business and never forget that they are here to make money at the end of the day. My wife and I are coming into some financial issues and we asked for a cancellation, I came in person to cancel they told us that we had to email in order to do a cancellation before our next billing cycle when I asked for a cancellation in person. The response we got we have to wait 60 days two months in order to cancel our membership. That doesn't sound reasonable at all not even apartments make you wait that long. "Fair" business practices is no more than 30 days notice? But 60?!? That's a money grab and a shady business practice in my opinion. Originally I wanted to put us on hold for a few months but now I know we will never be back again. It's all about the principal. At the end of the day again it's a business and they're here to make money, not change lives. MONEY IS KING!!!!! I would highly reconsider taking your child or anyone you know elsewhere my biggest regret is signing up with them in the first place. Shame on you for shady business practices!

I am a newer member to Javi's gym (November, 2019), but not to jiujitsu or martial arts. I have had…read morethe privilege to learn and train under world class instructors, which is the reason I sought out Javi in the first place, as his lineage, fighting experience, personality, and teaching style, exhibit the marks of such instruction. His brand of "Strike-Based" Jiujitsu, by name alone drew me to seek him out over all other jiujitsu schools in the Inland Empire, as it emphasizes that jiujitsu is first and formost a Self-Defense art. With respect to his academy, I am pleased that there is a respectful attitude amongst his students exhibited to eachother and extended to new sign-ups like myself, there are virtually no ego's displayed or felt during live rolls, and the mats and facilities are up kept and cleaned daily. I am excited to see how my growth in jiujitsu under Javi's instruction will blossom, and although I am relatively still new to his academy, based on what I have experienced and observed thus far, I recommend his academy to anyone looking to learn, develope, and expand their knowledge of Self-Defense offered through his jiujitsu instruction.
