From the reviews

My son has been going here for about three weeks. The instructors are awesome! The way they teach is refreshing to see. My son has a blast and looks forward to it every week. The best part is the discipline and exercise he gets.

★★★★★ — Ralph, Mar 2021

I have been training at Ultimate MMA under Andrew Calandrelli for a little over two years and you will not find a better gym with instructors of the highest quality and knowledge. Every class you attend you will learn something new, and the techniques taught are always broken down and explained extremely well.

★★★★★ — Chris, Mar 2015

I would definitely recommend Ultimate MMA/ Jiu Jitsu . I signed my daughter up to gain more self confidence and learn self defense. The coaching staff is great. As a parent, I very much appreciated Marisa's stern, yet caring, coaching methods.

★★★★★ — Dustin, Sep 2019

This gym is amazing both instructors marissa and Andrew are very informational and have a lot of experience in boxing, jujitsu, wrestling, and mma. I’ve been coming here for 2 years and everyday I learn something new. This is a great place for newbies, or experienced fighters. Any age and any experience level.

New to muay thai? Start at Ultimate MMA & Jiu-jitsu Training Center

Ultimate MMA & Jiu-jitsu Training Center 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 Ultimate MMA & Jiu-jitsu Training Center

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.
