From the reviews
This gym is fantastic. It is a very welcoming community stacked with top tier instructors. There is a disciplined culture of respect and mutual improvement here which helps you learn quickly and correctly.
Katharo training center is the best self-defense and Brazilian Jiu Jitsu in the Littleton and Denver area. Professor Steve Hordinkski is a compassionate and attentive coach. I have trained at a lot of gyms around the world and always feel at home with my training partners and instructors at Katharo.
Katharo Training Center is by far the best Jiu Jitsu school I’ve trained at in Colorado, having trained at Easton training center and High Altitude Martial Arts this school provides everything you would need for Jiu Jitsu. Professor Steve is a phenomenal coach and runs a top notch facility that is always clean!
The instructors are fantastic, humble, and willing to help and answer questions. The facility is excellent; in addition to the large mat for classes, there are smaller rooms for instruction and there's a substantial fitness area for crossfit and focus-based physical training, including an outside space for flipping…
New to BJJ? Start at Katharo Training Center - Jiu-Jitsu and Fitness
Katharo Training Center - Jiu-Jitsu and Fitness 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 Katharo Training Center - Jiu-Jitsu and 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.
