From the reviews

I dropped in for a couple classes this week and had an amazing time. Walking in, there was just a good feeling about the gym. The facilities are so clean and the coaches were very welcoming! To be honestly I was very nervous to drop in.

★★★★★ — Katrina, Jun 2020

A great gym. The kids are expected to work hard and it’s great to see how they progress over time. My once extremely timid daughter has come out of her shell thanks to the help of jiu jitsu. The coaches sincerely care about their students.

★★★★★ — Stephanie, May 2023

My husband and I dropped in this past Sunday for open mat and had a great time. We were traveling through and August replied to our voicemail promptly. The facility is very nice and in a shared building with a crossfit gym and we were able to shower before getting back into the car which was great.

★★★★★ — Mallory, Sep 2019

SIBJJ has exceeded my many expectations. I have previously trained in traditional Japanese Jiu-Jitsu and Karate over twenty five years ago. In high school I wrestled under a coach who trained the US national team.

New to BJJ? Start at Southern Idaho Brazilian Jiu Jitsu

Southern Idaho Brazilian Jiu Jitsu comes up as a beginner-friendly gym, going by their listing and members’ reviews. 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 Southern Idaho Brazilian Jiu Jitsu

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.
