Andreas "Andy" Hug was a Swiss karateka and kickboxer who competed in the heavyweight division. Considered to be one of the greatest heavyweight kickboxers of all time, Hug was renowned for his ability to execute numerous kicking techniques rarely seen in high-level competition. Although he was usually smaller than his opponents, standing at 1.80 m and being barely a heavyweight, weighing around 98.0 kg in his prime, he made up for his lack of size with his tremendous athleticism and speed. A southpaw, his trademark kicks included the axe kick and the "Hug Tornado", a low spinning heel kick targeting his opponents' thighs.

Kickboxing is a full-contact hybrid martial art and boxing type based on punching and kicking. Kickboxing originated in the 1950s to 1970s. The fight takes place in a boxing ring, normally with boxing gloves, mouth guards, shorts, and bare feet to favor the use of kicks. Kickboxing is practiced for self-defense, general fitness, or for competition. Some styles of kickboxing include: Full contact karate, Muay Thai, Japanese kickboxing, Lethwei, Sanda, and Savate.
