How to do waist and horse unity?

Bruce Lee elaborated on the basic power of modern combat, the so-called waist and horse unity, refers to whether we punch or kick, have to have the power of the waist with, in fact, in the real combat, the power of the waist accounted for most of the time, and we are now a lot of martial arts enthusiasts, practicing the existence of a misunderstanding is that the limbs of the muscle power is the main, but this is wrong, a lot of people to go to the gym to train the arm thick, all day bench press, deep squatting, but actually a paper tiger, combat combat is simply nothing, this is do not know how to power. All day bench press, squatting, fierce look, really strong, but in fact a paper tiger, combat is simply white, this is not know how to power, Chinese martial arts and foreign boxing in the practice method is very different, Chinese martial arts focus on both internal and external cultivation, foreigners focus on practicing muscle, which is correct? From my many years of experience in practicing kung fu, or our practice method is the best and most effective. We are not practicing muscles, but cultivating qi. Many people do not understand what is meant by practicing qi, and foreigners are even more difficult to find, we can find that some people look very muscular, but arm wrestling will be lost to a very thin person, why? Qi is not enough, this is the so-called strength. Of course, Bruce Lee is mainly external boxing, on the practice of gas nothing to pay attention to, but he spoke of waist and horse unity, is very reasonable, waist and limbs of the power to gather together to force, in order to achieve the maximum lethality of the opponent. Specific practice methods are, often do twisting movements, with the twisting machine, do twisting weight training, and then do kicking and punching air strikes, and with the sandbags to increase the explosive force, attention! Action must be standard, standard action is the key, many people do not pay attention to the standardization of action, think I kick a few targets, hit two sandbags sub, bang bang! It is very bluffing and powerful, this is wrong! It is even more stupid, the real master is the real battle honed out, not just hit these things can become a master. This is the basic practice method, I hope the majority of martial arts enthusiasts can be helpful
