From the reviews
Ironclad is more than a gym. It’s a family of a great people who work together to introduce a better lifestyle to their community. The owner, Kru John, helps all the students in any level to be better each session.
My two daughters and I have trained with Kru John for many years, and all three of us earned our black belts at Iron Clad. Early on, I often had to push my girls to attend class. Between school and other activities, they would have preferred almost anything else.
Wanting to get back in shape, so I did a trial period for IronClad’s Power Up Kickboxing. No hesitation when committing to the membership… As long as I live within a commutable distance, I will be a member. All of the instructors are fantastic.
My elementary age son has been taking classes at Iron Clad Martial Arts for 18 months now and it’s the best investment I’ve made! My son is a super active boy and struggles with focus and attention.
New to muay thai? Start at IronClad Martial Arts Center and Power-Up Fitness
IronClad Martial Arts Center and Power-Up Fitness 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 IronClad Martial Arts Center and Power-Up Fitness
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.
