Guy doubts the effectiveness of Kung Fu in a real fight
When you compare traditional martial arts to more modern, competition-based martial arts (BJJ or Muay Thai), is a lack of realism in their training.
All martial arts instructors and schools are different but for the most part traditional martial arts training does not involve full contact sparring or competition against a fully resisting opponent. Without that type of hard training, it is difficult to tell which techniques are truly effective in real-life scenarios.
In the video below we see an example of that very issue. While the Kung Fu practitioner isn’t completely inept he walks into a punch right off the bat. The Kung Fu guy is very fancy with his hand motions but it doesn’t do him any good as the other guy is able to land shots on him pretty easily.
The Kung Fu guy gets dropped less than a minute in and it looks to be over but he wants more. It starts up again and he then throws an okay looking spin kick but it doesn’t really land.
He starts to land some decent shots after that but he is brawling here, not using much technique. The other guy drops him with a big right hand, for good this time and the fight is over.
