From the reviews

I just had the opportunity to work with Neutral grounds in many different levels and I am amazed how well trained and disciplined the youth from this dojo are. After getting to know Evaldo and working with his students I am realizing that Evaldo does not only teach his students Jiujitsu techniques, he also teaches…

★★★★★ — Lazara, Mar 2014

This is an amazing BJJ facility family-oriented. Warm welcoming to everyone and all levels of self defense. I have seen my oldest become more confident and come out of his shell thru out the years. While taking Jujitsu and Wrestling.

★★★★★ — Xochitl, Jun 2023

Our son has been training at Neutral Grounds a once he was 4 years old, he’s turning 14 next month. From the first day we walked into the academy, we were welcomed with open arms. Professor Evaldo and the NG coaches have helped to shape our son into a confident, respectful, hard-working and kind young man.

★★★★★ — Chivy, May 2023

Utopia has been so amazing for our 4 yr old. He is so excited to go every week and watching his confidence and self esteem grow through each session, is incredible! Especially because he tends to be a bit shy and more observant at first.

New to muay thai? Start at Neutral Grounds JiuJitsu Academy. A USA Wrestling Charter Club

Neutral Grounds JiuJitsu Academy. A USA Wrestling Charter Club 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 Neutral Grounds JiuJitsu Academy. A USA Wrestling Charter Club

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.
