Khmer Boxer

A Khmer boxing match before the western ring was introduced

Pradal serey (ប្រដាល់សេរី) or Kbachkun Pradal Khmer is a Cambodian style of martial art. It is visually similar and evolved from the same martial arts tree of sibling arts such as Muay Thai from Thailand, tomoi from Malaysia, muay Lao from Laos, and lethwei from Myanmar. The term pradal serey means free fighting, from the Khmer words pradal (fight/boxing) and serey (free). Originally used for warfare, pradal serey is now one of Cambodia's national sports. Its moves have been slightly altered for the modern ring sport.

Pradal serey is the same as kbachkun boran except it does not include mae ("core techniques"), tvear (door system that emphasizes footwork) or weapons. Instead, it focuses more on winning a bout. While most well-known for its kicking technique, which generates power from hip rotation rather than snapping the leg, pradal serey consists of four types of strikes: punches, kicks, elbows and knee strikes. The clinch is also used to wear down the opponent. Compared to other forms of Southeast Asian kickboxing, pradal serey tends to emphasize more elusive and shifty fighting stances. The Cambodian style also tends to utilize more elbow techniques than that of other regions. More victories come by way of an elbow technique than any other strikes.
