Thai boxing (Muay Thai) is a combative sport and the national sport of Thailand, where it is known as “the art of eight limbs” — fighters strike with fists, elbows, knees and shins rather than the fists alone. Like boxing it is supervised by a referee and contested over timed rounds with a rest period between each one, and it adds the clinch, in which the two fighters fight for control at close range.
As a workout it draws on the same conditioning base as boxing — rounds on the pads and the heavy bag, footwork, and interval conditioning — while adding the kicking, kneeing and clinch work the sport is built on. That combination makes it a demanding full-body session: the legs and hips drive every kick, the core carries the clinch, and the round structure keeps the heart rate working in intervals throughout.
