From all the information about Bruce Lee acrobatics held by the author (John Lito), we can see that strength exercises account for a large proportion. Different from ordinary people's understanding of strength training, Bruce Lee's strength training focuses on functional training, including functional training of muscles, joints and related tissues in all parts of the body. Different from professional bodybuilders, Bruce Lee does not pursue big muscles, but pays attention to the "toughness" strength training of every muscle in the body, especially the joints. Anyone who has witnessed Bruce Lee's heyday will be deeply impressed by his amazing kung fu. How did he practice this "steel-like" body and that magical kung fu? How to practice those thick forearms whose edges and corners are like steel plates and whose waist and abdomen muscles are as clear as washboards? Here we open his fitness training diary to the world for the first time for everyone to learn. The most important thing is to be able to put it into practice, as Bruce Lee once said: "Theory alone is not enough, it must be used in practice; It is not enough to have determination. You must stay up late to lose weight. " ("knowing is not enough, it must be applied; It is not enough to have a will, we must do it. " ) Bruce Lee's strong muscles, formidable lines and incredible explosive power all represent a unique strength and momentum, and his muscle quality is unparalleled in the world. In his kung fu training, he often infiltrates some special strength exercises, such as dumbbell forearm combination exercises, dumbbell jumping over obstacles, stepping on piles, etc., to enhance balance and coordination. Although Bruce Lee has never participated in any form of bodybuilding competition, many world-famous bodybuilders admire this unique strength exercise and the quality and muscles developed based on it, including Lou Friege, Shawn Ray, Mai Materazzo, Kevin Liveris Felix Weiss, Sharon Bruno, and now Olympia Dorian Yates and Linda Molly. They all published personal opinions and articles, saying that Bruce Lee had a strong influence on their bodybuilding. Bruce Lee's strength training aims to help every part of the body "work hard". In other words, his muscles should not only be "beautiful", but also be "lethal" enough. He believes that the human body must first have good speed, agility, flexibility and endurance, and then it is the greatest absolute strength. If you don't have these qualities as the basis and pursue "muscle mass" unilaterally, you will be "fooled by fighters on the field like bison, or chased by rabbits like a broken tractor." (Excerpted from Bruce Lee's posthumous book How to Exercise Leg Muscles, tao of jeet kune do, O 'Hara Publishing Group). Herb jackson, an old friend and training partner of Bruce Lee, said that Bruce Lee's strength training always pursues a cucumber and egg slimming method that others can't imagine. In the late 1960s and early 1970s, Bruce Lee bought and "created" a large number of fitness equipment. Herb said that in 1973, Li built a "comprehensive training room" in Qihe villa in Hong Kong, and owned controllable sparring made of steel frames, steel cables and cotton bags at a high price. Unfortunately, Bruce Lee died before the birth of this "sparring" for training leg muscles. Later, when talking about the reason for making this "steel sparring", Herb said that the reason is very simple. Li has hit enough sandbags, and no one can hold his fist. He has practiced with a machine. In the video strength training of lovers kissing, Herb said that Bruce Lee especially loves strength training, and its strength is amazing. Danny inosanto is another good friend of Bruce Lee, and now he is the only coach authorized by Bruce Lee to teach martial arts. He is a teaching assistant in Bruce Lee, and helped Bruce Lee to establish Jeet Kune Do.
