★★★★★ — Jonathan, Feb 2025

Our child has been attending CJ Judo for over 18 months, having started at age five, and we couldn’t be happier with the experience. Coach Chuck is a naturally gifted educator who strikes the perfect balance between being firm, kind, and genuinely caring.

★★★★★ — Adam, Jan 2026

If I could give 6 stars, I would. Chuck is absolutely the best instructor my son's ever been with. Chuck is firm, kind, extremely knowledgeable, and such an incredible role model. This is a very safe learning setting - and the hands-on nature of judo helped my son prep for wrestling in high school (no judo in school).

★★★★★ — Vasant, Sep 2022

CJ Judo is top notch. Chuck is awesome with the kids and our kids stay engaged and challenged while having a ton of fun. My kids always walk out happier than when they arrive and that’s a pretty great sign CJ Judo is doing a great job along with teaching how to work hard, have fun, and not only be a great athlete, but…

New to judo? Start at CJ Judo

CJ Judo comes up as a beginner-friendly dojo, going by their listing and members’ reviews. If you've never stepped 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 sensei scale the intensity to you. Second, you'll start by learning to fall safely (ukemi) — reputable dojos build fundamentals (breakfalls, grips, a first throw and some groundwork) for weeks, live randori eases in gradually, and tapping early keeps everyone safe. Third, all levels really are welcome — ask about a dedicated beginners class time so your first session is alongside others who are also starting out, and remember to bow in and show respect (rei). Most dojos are happy to let you watch or try a class first, so reach out before you commit.

Your first judo class at CJ Judo

Nervous about walking into a judo dojo for the first time? Almost everyone is, and good sensei expect beginners to come through the door. Here's what to know. What to expect: a typical first class is a warm-up, learning to fall safely (ukemi), then drilling a throw or two and some groundwork with a partner — not hard randori. Rest whenever you need to; no one will bat an eye. What to wear: athletic wear you can move in (or a judogi if you have one); you'll train barefoot on the mats. What to bring: water and a mouthguard if you have one — many dojos lend a loaner judogi for a first class, so it's worth asking when you call. As you keep training you'll add your own judogi. Live randori eases in gradually, once your fundamentals are solid. Arrive 10–15 minutes early to sign a waiver and meet the sensei. It gets easier fast — most people feel far more at home by their third class.

Judo is a contact sport. Ease in, tap early and often, listen to your sensei, and if you have any injuries or health concerns, mention them before class and check with a doctor if you're unsure.
