From the reviews

I was so intimidated walking into jiu jitsu for the first time as a women and let me tell you everyone made me feel like I belonged there. All of the instructors are so kind and encouraging they make it easy to come back. Even though I’m a beginner and am slow to learn things they are always rooting for me.

★★★★★ — Danielle, Oct 2021

Catalyst Jiu Jitsu has extremely high-level instruction for Jiu Jitsu and kickboxing. The kids teams are extremely successful in local tournaments, and the adults are killers on the mats. But, the environment is friendly and supportive.

★★★★★ — Geoff, Oct 2021

My previous gym shut down and I was looking for a new place to train and after a few open mats and chats I signed up! The class format is different to most but its awesome. The instruction is top notch, friendly and also inclusive; they'll work with you rather than being dogmatic on how something has to be done.

★★★★★ — Aaron, Apr 2025

Very fun and cool team to train with. An awesome mid elevation training experience with some good guys and a solid team. Strong black belt force who like to encourage fundamentals and safety while allowing team training flexibility.

New to BJJ? Start at Catalyst Jiu-Jitsu - Loveland

Catalyst Jiu-Jitsu - Loveland 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 Catalyst Jiu-Jitsu - Loveland

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.
