People get usually martial art “sports” confused with “true self defense”.
“Sports” such as Tae Kwon Do, Boxing, Karate, Wrestling etc… are based on physical ability to be effective, such as flexibility in Tae Kwon Do, physical strength in Boxing and subsequent all other stiles. That is the reason why we do have weight classes in such events. Imagine a 150lb guy in a fight against a heavyweight!
Facts are that in realistic encounters you (given you are not the aggressor) will encounter one of three categories of opponents.
First, someone who is obviously stronger built than you.
Second, if this is not the case, he has a few friends with him who get the advantage back on his side.
Or third, if he is smaller and alone, watch out for weapons. These are the circumstances usually surrounding real encounters. Someone who is obviously in a disadvantage would not pick a fight with you.
These are the obvious reasons why “Self-Defensive Sports” work only partially or rarely when faced with an opponent in one of the above mentioned three categories. Not to lesson the effectiveness, yet it becomes obvious that such stiles effectiveness depend on the athletic ability of the applicant. Hence his/her conditioning, speed, flexibility and strength.
Realistic Self Defense teaches arts that takes physical disadvantage into consideration. There are few “true” stiles which work on such a level and a warning here - sadly many of them are taught with the wrong philosophy and under misconceptions, because only few people who claim the fame of having learned such systems know how to apply them.
Bruce Lee studied such stiles. One was called Wing Chun. He studied under Grandmaster Yip Man who was very thin and physically weak; an old man suffering from throat cancer! – yet Bruce Lee in his youth, even hot headed, listened very careful! Showing his strongest developed muscles was his brain! He studied under Yip Man for 5 years in Hong Kong and later on added also Filipino Martial Arts from his actual student Dan Inosanto, commonly referred to as Arnis, Escrima and Kali. (You can watch his introduction of Escrima to the western world in “Enter the Dragon”). Often falsely described as stick fighting system it is actually a multifaceted self defense system that also includes complex empty hand techniques. The empty hand stile is commonly referred to as Kadena de Mano and includes also training techniques to teach the senso-motoric nervous system rather than eyesight for response.
Long answer to a short question.
Bruce Lee was considered highly effective in terms of self-defense, which could be considered “strong” and at his time had no peers, but with his approximately 150lb body weight would have had many successors in terms of sheer physical strength. You will find most likely in every gym dozens of people who would have out bench pressed him, but anyone with good developed brain muscles should have refrained from picking a fight, because of Lee’s ability to apply true self-defensive skills most brilliantly, any obvious so-called apparent physical advantages as mentioned in the above 3 categories would have been negated.
P.S. Even though he applied many high kicks for show purposes in his movies he did not teach such techniques to his students.
