From the reviews

So I been doing Jiu jitsu for already 5 plus years now except during the time covid hit. I took off the entire 2020 and early 2021. I was giving the ok to start training at end of 2021 so I was in search of a new school . I went on Yelp and found this place.

★★★★★ — Vinny, Feb 2022

I love training at San Lorenzo BJJ. The mats are clean and training partners are friendly. Manny teaches high level technique with game-changing details that I'm able to implement in rolls instantly. He cares about making an impact to the community, his students, and creating a healthy environment at all costs.

★★★★★ — Andrew, Jul 2021

San Lorenzo BJJ (SLZBJJ) is a very warm and welcoming jiu jitsu school. The students are very respectful to each other and guests. They make sure to acknowledge everyone who comes through the door, which can be a huge relief when you’re doing drop ins or trial classes because you instantly feel like you belong there.

★★★★★ — Stephen, Aug 2023

I’ve know Manny the owner since we were both white belts. Manny is one of most well mannered and respectful person I’ve meet when it come to teaching and running a jiu jitsu gym. I had a chance to come visit him for his open mat on Sunday and was amazed of how welcoming he was.

New to BJJ? Start at San Lorenzo Brazilian Jiu Jitsu

San Lorenzo Brazilian Jiu Jitsu comes up as a beginner-friendly gym, going by their listing and members’ reviews. If you've never rolled or set foot on a mat, that's exactly who a good beginners program is for. A few things worth knowing before your first week. First, you don't need to be fit or flexible to start — you get in shape by training, not before it, and coaches scale the intensity to you. Second, you won't be thrown into hard rolling — reputable gyms build fundamentals (positions, escapes, and basic submissions) for weeks, live rolling eases in gradually, and tapping early keeps every roll safe. Third, all levels really are welcome — ask about a dedicated beginners or fundamentals class time so your first session is alongside others who are also starting out, and leave your ego at the door. Most gyms are happy to let you watch or try a class first, so reach out before you commit.

Your first BJJ class at San Lorenzo Brazilian Jiu Jitsu

Nervous about walking into a BJJ gym for the first time? Almost everyone is, and good coaches expect beginners to come through the door. Here's what to know. What to expect: a typical first class is a warm-up, then drilling basic positions and escapes with a partner — not hard sparring. Rest whenever you need to; no one will bat an eye. What to wear: athletic wear you can move in (or a gi if you have one); you'll train barefoot on the mats. What to bring: water and a mouthguard if you have one — many gyms lend a loaner gi for a first class, so it's worth asking. As you keep training you'll add your own gi (or a rashguard and shorts for no-gi) and a mouthguard. Live rolling eases in gradually, once your fundamentals are solid. Arrive 10–15 minutes early to sign a waiver and meet the coach. It gets easier fast — most people feel far more at home by their third class.

BJJ is a contact sport. Ease in, tap early and often, listen to your coaches, and if you have any injuries or health concerns, mention them before class and check with a doctor if you're unsure.
