★★★★★ — Denver, Sep 2024

Sub Spectrum BJJ puts on a fantastic tournament! We were so impressed by how well-organized everything was, and it created such a positive and encouraging environment for the kids. The energy at the tournament was amazing! This was our sons' first time competing (they're 7 and 10), and they loved it!

★★★★★ — Donna, Sep 2024

The absolute best tournament I've ever had the pleasure of doing. They run on time and keep everyone updated on changes to brackets, times, or mat changes to keep things running smoothly.

★★★★★ — Timmie, Sep 2024

Great tournament host and wonderful team behind the scenes. My girls hasn't been able to actively participate until now due to low prospects for their divisions. Refunds were promptly processed as needed.

Your first BJJ class at Sub Spectrum Jiu Jitsu Tournaments

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.
