    • Welcome!

      Welcome to Kaizen Karate & Self-Defense in Windsor, CO! We offer Karate classes for children ages 3 and up, women's self-defense classes, and private lessons for Karate and self-defense -- including private group self-defense classes and company team-building classes.

      We are located in the shopping center on the southwest corner of Main Street and 11th Street, in the parking lot with Egg & I, and next door to Brick Oven Pizza. We are the premier martial arts school and self-protection specialists serving Windsor, Severance, east Loveland, southeast Fort Collins, and west Greeley.

      Why choose us? Our teaching method combines the discipline and practical self-defense applications of traditional Japanese Karate with the "I Refuse to be a Victim" mentality for the street. We specialize in self-protection for both adults and children -- including anti-bullying, verbal self-defense, "stranger danger" and more. We are also proud members of the Colorado Karate Association (CKA), and we compete in CKA tournaments throughout the year. We've produced two CKA State Champions in two years!

      At Kaizen Karate & Self-Defense, we believe karate and self-defense training is a life skill. And it can be practiced by people of almost all ages. In addition to the wonderful physical fitness and self-protection benefits, children develop fine motor skills, coordination, perseverance and self-discipline during karate training. Livestrong.com says, "Children who get involved in martial arts reap many benefits in several areas of life... Martial arts help instill mental focus in your child, giving her the ability to concentrate on a task and see it through to its conclusion. The discipline that is taught in the dojo in regard to uniforms, customs and techniques often translates into other areas of life, including school and household chores."

      For adults, it is a great way to learn self-defense and get in shape at the same time. Healthfitnessrevolution.com says, "Not only is it a great activity that keeps participants physically active, but it instills a sense of achievement and ethics, as you work your way up to earning a black belt. But even if you have no previous experience in martial arts, it is still a great activity to pick up even as an adult." They list their top 10 benefits of martial arts training, including a healthy lifestyle, improved cardiovascular health, weight loss and self-confidence.

      Thanks for visiting our site and we look forward to seeing you in class!
