Martial Arts in Belmont, MA

‍Kaizen Karate & Martial Arts is a family-run Kenpo karate studio in Belmont, MA, led by Arlington residents Jeremy Kriegel, Sharona Jacobs, and their teenaged daughter, Lilia Jacobs-Kriegel. We foster a warm, family-like atmosphere where every student is part of a close-knit community. As a family, we practice what we preach by supporting other families in their training and growth.

- A dojo that feels like family — however you define family.

‍

At Kaizen Karate, martial arts are more than just punches and kicks — they’re a way to build strong bodies, confident minds, and close connections. Whether you’re a parent sharing something meaningful with your kids, an adult returning to training, or someone discovering karate for the first time, you’ll find a place here.

‍

We teach the why behind every move — so you understand how karate shapes your body, sharpens your focus, and enriches your life. It’s about thoughtful learning, not just memorizing forms.

‍

We celebrate all kinds of families and learners. Whether you’re training with your immediate family, your partner, your chosen family, or flying solo, Kaizen Karate is a community that welcomes you just as you are. Our classes adapt to meet you where you are — whether recovering from injury, new to martial arts, or looking for a fresh challenge. No matter your age, fitness level, or background, you’ll find a supportive, inclusive environment that celebrates all identities and abilities.
