Have you ever been so mad you could punch something? Maybe you even did, taking your aggression out on a pillow or couch cushion. Although this impromptu aggression might feel satisfying in the moment, there's an even better way to use physical action to keep your stress levels at bay: kickboxing. Kickboxing is a form of martial arts derived from karate. It borrows moves from multiple types of martial arts including full-contact karate, Muay Thai, and boxing.
