Karate is NOT just a straight punch...

While my classmates were doing their homework properly (or not at all), I was drilling types of the fist: shape + name. Out loud.

Seiken. Uraken. Tettsui. Ippon, Nihon, Yonhon Nukite.

And there are many more...

You probably know the different forms/shape of the hand —but do you KNOW them? Can you apply them without hurting yourself in a dynamic situation AND do you know when to use which one? 🤷‍♂️

I had NO CLUE when I got Ishikawa sensei's book. I designed the drill above (originally it's longer) to memorise the shape and the names.

Pretty cool, but it didn't help.

In fact... I hurt myself when I put it to the test.

It's an embarassing story really ... I (tried to) use Haito to hit one of those punching-balls on a fair. That didn't end well for my elbow. I had to seriously man-up to hide the pain for using it the wrong way.

Hey, what did I now... I was 15!


The fact is, many Karateka dream about knowing all the fancy stuff. Weird hand shapes and ways to strike...

...but when you're in the Dojo, all you do is a straight punch, Uraken and maybe Shuto and Shotei if you're lucky. 

I was fortunate to learn from Ishikawa sensei who taught me A LOT of those (I hesitate to say nasty) nasty moves.

It was only years later that I started to see how all were connected fundamentally. 👇

In "Mastering Shiyobui" I teach you everything I learned from Ishikawa sensei put in a neat package with highly specific fundamental teaching that connects the dots straight away.

For example, maybe you've seen "Koken" in the movies or on YouTube being performed by an old master. 

It's one of my favorite techniques for close range fighting (fast, surprising and pretty much invisible if done right)... so YOU can pull it off too... 

Would you like to know how to use it, train it, from what angle, when and where to hit? And for the other 22 ways too?

Here's what Matthew Said

This course definitely did not disappoint!

The new ways to apply the fists were eye opening and the application for kumate was very informative. Because of that, I'll definitely be keeping my mind open to even more ways to apply the basics beyond what I've learned. 

I'm glad that I got it and would definitely recommend this series to anyone who wants to study the basics of karate in a new way.
