From the reviews

EDIT- Well according to Google it has been 7 months since I made this review. I have a few more training hours under my belt, but I still feel the same way about Jiu Jitsu & Kick Boxing Unlimited. I enjoy going as much as I can for the camaraderie and the physical training.

★★★★★ — Zachary, Feb 2024

I am a new Jui-jitsu mother and I wasn't sure what to expect in the beginning. My husband and daughters love training here and they all have different attitudes and abilities. This was one of the reasons for my reservation, but the professor has got thru to each of them and is teaching them so much.

★★★★★ — Michelle, Aug 2024

I will try to keep this short, but I cannot say enough good things about Professor John and this school. What a gem to find in the area. We lived there less than 2 years, but of the things we’ll miss, this place takes the cake.

★★★★★ — Molly, Apr 2025

I was visiting Siouxland and wanted to hit the gym for some jiu-jitsu. I was able to find this gym- FYI, Google maps will get you to Planet Fitness parking lot, so if you get lost Jiu-jitsu and Kickboxing Unlimited is to the right of planet fitness. The gym has a good atmosphere very welcoming.

New to BJJ? Start at Jiu Jitsu Unlimited

Jiu Jitsu Unlimited 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 Jiu Jitsu Unlimited

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.
