From the reviews

My kids started here in January. My husband started shorty after. I recently started after my husband talked me into it. We were all able to try the free trial. Finding this place has been a blessing. My kids 10, 5 love it and have already grown so much.

★★★★★ — Erica, May 2025

My kids have been coming to Sampa for a year now. My son has really opened up not only socially but he is more attentive and disciplined. The coaches and professor are great, they really care about the kids.

★★★★★ — Ernesto, Nov 2025

I am a retired military veteran and a stay at home dad. I tried so many sports but my young daughter prefers Jiu Jitsu. She is very committed to the art. She has been with Sampa for over 3 years and has been taught by all the Professors and coaches. She loves and respects all of them.

★★★★★ — Javier, Oct 2023

We’ve been part of the Sampa Jiu Jitsu Academy family for just about a month now, and we are already seeing incredible progress with our son, who turns 4 in August. Enrolling him even a few months shy of 4 in the 4–7-year-old class has been one of the best decisions we’ve made.

Your first BJJ class at Sampa Brazilian Jiu Jitsu Fontana

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.
