Real Kung Fu is not about using steroids or performance enhancing drugs. It's about training hard and natural. It's about a natural muscle development, it is about life long health and wellness. Real Kung Fu is not a shock of before and after, Real Kung Fu is seeing someone who is 21 and then 50 years later at the age of 71, he almost looks the same! His body has stayed young because he has taken care of his health in a natural way. The pictures below are not Real Kung Fu, it is fake, it is science, it is unnatural, it is unhealthy, it is like a Lance Armstrong, fraudulent.
