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 Krav Maga? Start at IronClad Martial Arts Center and Power-Up Fitness
IronClad Martial Arts Center and Power-Up Fitness comes up as a beginner-friendly school — noted on their own site. If you've never thrown a punch or set foot in a self-defense class, 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 or athletic to start — you get in shape by training, not before it, and instructors scale the intensity to you. Second, you won't be thrown into hard sparring — reputable schools build the fundamentals (stance, movement, and core self-defense techniques) over weeks, and controlled pressure-testing eases in gradually so every drill stays safe. Third, all levels really are welcome — ask about a dedicated beginners or Level 1 class time so your first session is alongside others who are also just starting out. Most schools are happy to let you watch or try a class first, so reach out before you commit.
Your first Krav Maga class at IronClad Martial Arts Center and Power-Up Fitness
Nervous about walking into a Krav Maga school for the first time? Almost everyone is, and good instructors 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 a few core techniques with a partner — controlled and at your own pace, not hard sparring. Rest whenever you need to; no one will bat an eye. What to wear: comfortable athletic clothes you can move in — there's no uniform or special gear you need to buy to get started. What to bring: water and a mouthguard if you have one — most schools have everything else you'll need for a first class, so it's worth asking when you call what to bring. Pressure-testing eases in gradually, once your fundamentals are solid — you won't be sparring hard on day one. Arrive 10–15 minutes early to sign in and meet the instructor. It gets easier fast — most people feel far more at home by their third class.
