From the reviews

I walked in to Primal Gym in September 2018 about a good 30 pounds overweight, someone who was not confident in himself, and someone who so badly wanted to change his life for the better, but couldn't just get out of his own way. As a fan of boxing, I came across Primal Gym through an online search.

★★★★★ — Sean, May 2019

I have trained with Jim for a number of years, and I recommend that you give Primal Jym a try. Whether you are just beginning or have been training for a while, you won’t be disappointed.

★★★★★ — Biagio, Apr 2025

Primal Jym has truly become my safe space and my outlet to release all the stress from the day. I’m grateful for all the coaches, but I have to give the biggest shout out to Coach Vicky, because she is truly one of a kind. From day one, she has been such a constant source of support in my fitness journey.

★★★★★ — Hilcia, Jan 2026

I had the privilege of training with Jim McCann in JKD. He's a great instructor that teaches in a simplistic manner. Being extremely knowledgeable about martial arts, he doesn't just show you a technique but also explains why it is effective (or ineffective).

New to muay thai? Start at Primal Jym

Primal Jym 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 Primal Jym

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.
