From the reviews

I drive 75 minutes each way to NPI 3X per week SPECIFICALLY so my twin 13 year olds can train under Professor Leandro Hernandez. My kids have been training 7 years. They started with Leandro & after trying several schools? We always end up back with Leandro.

★★★★★ — Bruce, Oct 2025

As a fighter who’s been training my entire life, I’ve finally found a place where I can truly grow and learn. Being coached by someone who’s experienced every high and low and reached the top of nearly every organization has given me real confidence that I’m being guided down the right path, not only as an athlete but…

★★★★★ — Ethen, Oct 2025

I have been training at this facility for about 3 months now. I am new to martial arts and to be honest I was a little bit intimidated to sign up. The coaches here have made me feel comfortable and they take the time to explain all my questions. I take the BJJ and Boxing classes.

★★★★★ — John, Oct 2025

One of the best gyms my children and I have ever trained at. Great facility and undisputed world class instructors

New to BJJ? Start at Eddie Alvarez's Underground Kings

Eddie Alvarez's Underground Kings 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 Eddie Alvarez's Underground Kings

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 when you call. 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.
