Lee's first introduction to martial arts was through his father, from whom he learned the fundamentals of Wu-style tai chi. In his teens, Lee became involved in Hong Kong gang conflicts, which led to frequent street fights. The largest influence on Lee's martial arts development was his study of Wing Chun. Lee was 16 years old under the Wing Chun teacher Ip Man, between late 1956 and 1957, after losing to rival gang members.

Ip's regular classes generally consisted of form practice, chi sao (sticking hands) drills, wooden dummy techniques, and free sparring. There was no set pattern for the classes. Other Chinese martial arts styles Lee trained in were Northern Praying Mantis, Southern Praying Mantis, Eagle Claw, Tan Tui, Law Hon, Mizongyi, Wa K'ung, Monkey, Southern Dragon, Fujian White Crane, Choy Li Fut, Hung Gar, Choy Gar, Fut Gar, Mok Gar, Yau Kung Moon, Li Gar, and Lau Gar.

Lee was trained in boxing, between 1956 and 1958, by Brother Edward, coach of the St. Francis Xavier's College boxing team. Lee went on to win the Hong Kong Schools boxing tournament in 1958 while scoring knockdowns against the previous champion Gary Elms in the final. After moving to the United States, Lee was heavily influenced by heavyweight boxing champion Muhammad Ali, whose footwork he studied and incorporated into his style in the 1960s.

Lee demonstrated his Jeet Kune Do martial arts at the Long Beach International Karate Championships in 1964 and 1968, with the latter having higher-quality video footage available. Lee is seen demonstrating quick eye strikes before his opponent can block and demonstrating the one-inch punch on several volunteers. He demonstrates chi sao drills while blindfolded against an opponent, probing for weaknesses in his opponent while scoring with punches and takedowns. Lee then participates in a full-contact sparring bout against an opponent, with both wearing leather headgear.

Lee is seen implementing his Jeet Kune Do concept of economical motion, using Ali-inspired footwork to keep out of range while counter-attacking with backfists and straight punches. He halts attacks with stop-hit side kicks and quickly executes several sweeps and head kicks. The opponent repeatedly attempts to attack Lee but is never able to connect with a clean hit. He once managed to come close with a spin kick, but Lee counters it. The footage was reviewed by Black Belt magazine in 1995, concluding that "the action is as fast and furious as anything in Lee's films."

It was at the 1964 championships that Lee first met taekwondo master Jhoongoo Rhee. While Rhee taught Lee the side kick in detail, Lee taught Rhee the "non-telegraphic" punch. Rhee learned what he calls the "accupunch" from Lee and incorporated it into American taekwondo. The "accupunch" is a rapid fast punch that is very difficult to block, based on human reaction time—"the idea is to finish the execution of the punch before the opponent can complete the brain-to-wrist communication."

Lee commonly used the oblique kick, made popular much later in mixed martial arts. It is called the jeet tek, "stop kick" or "intercepting kick", in Jeet Kune Do.
