The above video is an great example of what real people don’t look like when fighting. It provides a stylized view of trained fighters using scripted techniques of attack, counter-attacker, and counter-counter-attack. The next video demonstrates what real people actually look like when they fight.
It is important to understand the difference between fantasy and reality in order to have a realistic baseline for what physical self-defense training can and cannot do for you. No amount of training for the people in Video #2 will make them look like the people in Video#1 because Video #1 depicts a “fantasy fight” which has the sole purpose of entertainment.
Fantasy or reality? You be the judge.
