In martial arts training it's important to have a healthy understanding of many different types of weapons, lengths, sizes and characteristics. Our training in traditional martial arts gives us a wide variety of those types of weapons. And so, it exposes us to a lot of different characteristics that we can use to refine our instincts for adaptation. Which then helps us to be as adaptive and flexible in a real situation. Even now today in the real world, after we've studied a wide variety and spectrum of weapons in the traditional world of martial arts. So, that's just a little bit about why we use traditional so prevalently in our training. Because they are critical to understanding how to adapt to your environment.
