From the reviews

Excellent instructors, both morning and Sunday classes, haven't had a chance yet to go to afternoon weekday classes yet but they have the same instructor as the Sunday classes so I have confidence they'll be great!

★★★★★ — Aj, May 2022

I have been training at NJ United for over 3 years and honestly it is the best decision I have ever made in terms of fitness. They are absolutely the best gym with great coaches that care about you as much as your training.

★★★★★ — Victor, Mar 2020

We absolutely love Hector! He is the best personal trainer I ever had! He is so encouraging, knowledgeable, fit and most of all patient. I’m not an easy client but he motivates me and now I’m stronger and I’m losing weight!

★★★★★ — Marietta, Aug 2024

I was visiting from Wisconsin and had the opportunity to drop in for the Muay Thai classes—what a great experience! From the moment I walked in, I was welcomed into a supportive and friendly environment. The culture here is top-notch, with a great group of people.

New to muay thai? Start at NJ United Mixed Martial Arts

NJ United Mixed Martial Arts comes up as a beginner-friendly gym — noted on their own site. 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 NJ United Mixed Martial Arts

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.
