He has "an unstoppable punch"

Bruce Lee participated in the 1964 Long Beach International Karate Championships at Parker's invitation and repeatedly executed two-finger push-ups with feet spaced roughly shoulder-width apart. Additionally, he performed a "one-inch punch" at the same Long Beach event. In front of a partner who is standing still, Lee is straight and has his right leg in front with a slightly bent knee. The distance between Lee's right fist and his partner's chest was around an inch (2.5 cm). His right arm was partially extended. Lee then hit volunteer Bob Baker while essentially maintaining the same posture, shoving Baker backward and crashing onto a chair that was purportedly put behind Baker to protect him from harm, though Baker's momentum quickly causes him to fall to the ground. Baker remembered, "Bruce was instructed by me to cease his protesting. The last time he punched me, the pain in my chest was so excruciating that I had to skip work."

Bruce Lee is regarded as a master of combat because of some of his spectacular maneuvers, such as his "Unstoppable Punch." Lee asserted with great assurance that no opponent could stop him because of the speed of his fists. At the 1967 Long Beach International Karate Championships, a test was done to determine whether Lee had the capability. Vic Moore, a four-time Karate World Champion and tenth-dan black belt, will be Lee's rival in this match. Everyone was startled when Lee hit Moore in the face eight times during the match and Moore was unable to deflect any of the blows. An important detail about Bruce Lee is that he was able to demonstrate his point in this competition.
