We love Ripple Effect Martial arts in our family! We have been attending as a family for the last 3.5 years. Our youngest was 2 months old when we started. The staff was super supportive and enabled us to attend class together even with the baby in tow. Now the youngest is 3.5 and has joined classes as well.

★★★★★ — Jennifer, Jan 2026

The mental and physical strength the REMA has given my boys is beyond words. I wish I had learned this discipline when I was growing up. My son's are respectful, courteous and all around good, well rounded guys.

★★★★★ — Gregory, Oct 2025

Fantastic instructors at Ripple Effect Martial Arts here in Longmont! My most favorite instructors include the enthusiastic Mr. Brooks, the consistent Ms. Whitlow, the dedicated Mr. Matthew, and all the impressive junior instructors who all help create a space of energy and joy in the studio!

New to Karate? Start at Ripple Effect Martial Arts

Ripple Effect Martial Arts comes up as a beginner-friendly dojo, going by their listing and students’ reviews. If you've never thrown a punch or set foot in a dojo, 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 the sensei scales the intensity to you. Second, you won't be thrown into hard sparring — reputable dojos build fundamentals (stances, blocks, punches, and kicks) for weeks, and kumite (sparring) eases in gradually, with pads and control. Third, all levels and ages really are welcome — ask about a dedicated beginners or fundamentals class time so your first session is alongside others who are also starting out. Most dojos are happy to let you watch or try a class first, so reach out before you commit.

Your first Karate class at Ripple Effect Martial Arts

Nervous about walking into a Karate dojo for the first time? Almost everyone is, and a good sensei expects 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 stances, blocks, punches, and kicks — not hard sparring. Step to the side 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. What to bring: water, and a mouthguard if you have one — many dojos 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 and the belt your dojo awards you. Kumite (sparring) 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.

Karate is a contact sport. Ease in, train within your limits, listen to your instructors, and if you have any injuries or health concerns, mention them before class and check with a doctor if you're unsure.
