From the reviews

My kid loves this place. Instructors are all very engaged and helpful. Not "dictators" but still able to teach respect and discipline. John is the owner and is always there....

★★★★★ — Craig, Jan 2020

I’ve watched my first two children blossom here - my stepson is a teen now and about to test for brown belt, and it has given him so much confidence and athleticism. My daughter has been going since age 4 and is now 7, and this is her only consistent activity over the years.

★★★★★ — Dr., Jul 2024

Very family-friendly place! The dojo is always clean and the instructors are energized and inspiring. I have watched my stepson blossom since starting karate here - he is much more focused and respectful at school and home, more confident in his everyday life, and is more coordinated.

★★★★★ — Carole, Nov 2017

The z ultimate Broomfield location is the best instruction I have received in my quest for a black belt in the kempo martial arts! I am very pleased with the friendly staff, and students at this location! I would highly recommend this dojo for training in the martial arts!

Your first BJJ class at Z-Ultimate Self Defense Studios

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.
