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 muay thai? 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 thrown a punch or a kick, 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 to start — you get in shape by training, not before it, and coaches scale the conditioning to you. Second, you won't be thrown into sparring — reputable gyms build fundamentals (stance, footwork, and the basic strikes of the "art of eight limbs") for weeks before any contact, and sparring stays optional. 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. Most gyms are happy to let you watch or try a class first, so reach out before you commit.

Your first muay thai class at Eddie Alvarez's Underground Kings

Nervous about walking into a muay thai 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 the basics on pads and bags — not fighting. Rest whenever you need to; no one will bat an eye. What to wear: shorts or athletic wear and a t-shirt; you'll train barefoot on the mats. What to bring: water and hand wraps if you have them — many gyms lend gloves for a first class, so it's worth asking when you call. As you keep training you'll add your own gloves, wraps, a mouthguard, and shin guards. Sparring is optional and comes later, 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.

Muay thai is a contact sport. Ease in, 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.
