Much like understanding grammar is a basic for learning how to write, understanding the beginning tenants of any Martial Art is essential to it’s practice. The basics are the building blocks of technique, any technique, from being a excellent painter to handling a firearm. As a writer, we control everything that happens in a character’s universe, so it’s essential to understand not just how something works but what it does and why it’s important.
It’s tempting to want to just jump straight to the action, but for the sake of your characters and writing believable fight scenes, it’s important to walk before you run. Just as How? What? Where? and Why? are important questions to a story’s plot, they are also important to a punch or a kick.
The basics are what teach us the how, the what, and the why so we can perform in the where. Master your basics and you start mastering your character. There will always be someone in your audience who will know if you don’t put the work in and for those that didn’t, they might learn something new.
