A grappling hold (commonly referred to simply as a hold; in Japanese referred to as katame-waza, 固め技, "grappling technique") is a grappling, wrestling, judo or other martial arts term for a specific grip that is applied to an opponent. Holds are principally used to control the opponent, and to advance in points or positioning. Holds may be categorized by their function such as clinching, pinning, pain compliance or submission, while others can be classified by their anatomical effect: chokehold, joint-lock or compression lock.

A clinch hold (also known as a clinching hold) is a grappling hold which is used in clinch fighting with the purpose of controlling the opponent. In wrestling it is referred to as the Tie-up. The use of a clinch hold results in the clinch. Clinch holds can be used to close in on the opponent, as a precursor to a takedown or throw, or to prevent the opponent from moving away or striking effectively. Typical clinch holds include:

A pain compliance hold (also referred to as a pain compliance technique or sometimes a pain hold) is a grappling hold which uses painful joint lock, compression lock or pressure point technique to control a person or opponent. The mechanism of the techniques is the same of submission holds. However, pain compliance techniques are generally used by law enforcement^{[citation needed]}, and often taught as a self-defense technique in martial arts and combatives.

Bruce Lee (born Lee Jun-fan; 27 November 1940 – 20 July 1973) was a Chinese AmericanHong Kong actor,martial arts instructor, philosopher, film director, film producer, screenwriter, and founder of the Jeet Kune Do martial arts movement. He is widely considered by many commentators, critics, media and other martial artists to be the most influential martial artist and pop culture icon of the 20th Century. He is often credited with changing the way Asians were presented in American films.

Lee was born in San Francisco to parents of Hong Kong heritage but was raised in Hong Kong until his late teens. Lee returned to the United States at the age of 18 to claim his U.S. citizenship and receive his higher education. It was during this time that he began teaching martial arts, which soon led to film and television roles.

His Hong Kong and Hollywood-produced films elevated the traditional Hong Kong martial arts film to a new level of popularity and acclaim, and sparked a major surge of interest in Chinese martial arts in the West in the 1970s. The direction and tone of his films changed and influenced martial arts and martial arts films in Hong Kong and the rest of the world, as well. He is noted for his roles in five feature-length films: Lo Wei's The Big Boss (1971) and Fist of Fury (1972); Way of the Dragon (1972), directed and written by Lee; Warner Brothers' Enter the Dragon (1973) and The Game of Death (1978), both directed by Robert Clouse.
