Sensei MJ Singh shares the benefits of his extensive martial-arts training with students both young and old. During his karate for kids classes, Singh provides high-energy fun for tykes as they master not only self-defense, but also self-discipline, which may give them the fortitude to complete schoolwork and staring contests against teddy bears. For teens, he blends the techniques of western boxing, wrestling, Brazilian jujistu, and muay thai into a comprehensive mixed martial-arts class. He also welcomes parents to train alongside their kids. If adults seek a full-grown fitness regimen, they can enroll in cardio-focused fitness kickboxing classes or take krav maga self defense, which was developed for and by the Israeli Defense Force.
