From the reviews
Premier MMA gym In the SFV. Professor Gabe does an excellent job passing down his extensive knowledge of BJJ and MMA to his students. Great coaches as well. One of the best decisions I ever made was joining Kaiju !
I have been training at Kaiju for roughly 2 years now under Professor Gabe, Professor Brian, and Professor Adrian, as well as under Coach DC for striking. I have to say that the curriculum in the gym is absolutely top notch, and one excellent benefit of multiple black belts is that there is a great variety of styles…
As the second oldest student at the gym, my days are limited and training at a supportive and family oriented gym is important. Professor Gabe always goes the extra mile to train all his students (including old ass folks) with unlimited enthusiasm, superb skill, and extreme patience.
Professor Gabe Ruediger from Kaiju MMA & Fitness in Tarzana, Ca. put on an EXCEPTIONAL Jiu Jitsu Seminar at T7JJ with Professor Brian Hummel for our 2 year anniversary event. Thank You Both! If in the Tarzana area I highly recommend visiting Kaiju MMA & Fitness, Professor Gabe and his Team!
New to BJJ? Start at Kaiju MMA & Fitness
Kaiju MMA & Fitness 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 Kaiju MMA & Fitness
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.
