From the reviews

I’ve been training at this Martial arts gym with Sam for a while now, and it’s honestly a great experience. Sam is one of those rare instructors who’s not just skilled, but also a genuinely gifted teacher.

★★★★★ — David, Nov 2025

My experience here has always been great. Sam’s ability to not only teach jiu-jitsu but also share life experiences and advice is what separates him from other instructors. The students here are also fantastic to work with, they all are eager to help and guide you with whatever moves or positions you need help with.

★★★★★ — Abraham, Jan 2026

I have been attending MMAA for just under 2 months now, and I learn so much in every class I attend. Sensei Sam genuinely cares about the growth and development of each one of his students, and I'm very happy with my decision to join.

★★★★★ — John, Nov 2025

Our daughter is now in her third year at Marcellini's Martial Arts Academy, and we truly couldn’t be happier with the experience. Before finding this academy, we tried several different activities and programs, but nothing really clicked for her.

New to BJJ? Start at Marcellini's Martial Arts Academy - Riverside

Marcellini's Martial Arts Academy - Riverside 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 Marcellini's Martial Arts Academy - Riverside

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.
