Tae Bo is a body fitness system that incorporates martial arts techniques, such as kicks and punches, which became popular in the 1990s. It was developed by American taekwondo practitioner Billy Blanks. The name Tae Bo is a portmanteau of taekwondo and boxing. Tae Bo classes are taught worldwide and include many of the same punches and kicks as karate, but it is not intended for fighting or self-defense activities. There are no throws, grappling moves, or ground fighting techniques in Tae Bo. Its only intent is to increase fitness through movement. It also includes aerobic exercises intended to strengthen all muscles of the body with basic choreography. The high-intensity workout is intended to increase cardiovascular fitness, strength, muscular endurance, and flexibility. Tae Bo has been characterized as an excellent exercise for weight loss, as it can burn up to 800 calories per hour.
