From the reviews

We got to IA in 2023. While searching for a place for my daughter to learn to defend herself, we found the academy. Since day 1, teacher has shown us his professionalism, knowledge, and passion for teaching others. Most importantly, he shows his students the importance of following God’s path and helping people.

★★★★★ — Cynthia, Sep 2024

My daughter and i have Both been taking jiujitsu classes for 8 months now and we could not be happier! I was On the heavier side and I’ve lost a lot of weight as well as learning a bunch of self defense I’m more confident in all things now.

★★★★★ — Kindra, Oct 2021

Extremely professional school, as a current student who has attended now over a year I feel the teacher has phenomenal skills and the ability to properly train most people.

★★★★★ — Chandler, May 2024

I have been attending adult classes at Kingdom Warrior Jiu Jitsu Academy for almost a year, training about twice a week. In that time, I’ve gained a ton of knowledge and skill in a sport in which I was previously unfamiliar. I’ve gotten into much better physical shape and cardiovascular condition.

New to BJJ? Start at Kingdom Warriors Jiu Jitsu Academy

Kingdom Warriors Jiu Jitsu Academy comes up as a beginner-friendly gym — noted on their own site. If you've never rolled or set foot on a mat, 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 flexible to start — you get in shape by training, not before it, and coaches scale the intensity to you. Second, you won't be thrown into hard rolling — reputable gyms build fundamentals (positions, escapes, and basic submissions) for weeks, live rolling eases in gradually, and tapping early keeps every roll safe. 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, and leave your ego at the door. Most gyms are happy to let you watch or try a class first, so reach out before you commit.

Your first BJJ class at Kingdom Warriors Jiu Jitsu Academy

Nervous about walking into a BJJ 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 basic positions and escapes with a partner — not hard sparring. Rest whenever you need to; no one will bat an eye. What to wear: athletic wear you can move in (or a gi if you have one); you'll train barefoot on the mats. What to bring: water and a mouthguard if you have one — many gyms lend a loaner gi for a first class, so it's worth asking when you call. As you keep training you'll add your own gi (or a rashguard and shorts for no-gi) and a mouthguard. Live rolling eases in gradually, 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.

BJJ is a contact sport. Ease in, tap early and often, 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.
