Tenouchi and swinging - basic practice drill
This term we will be focusing on tenouchi 手の内. To review the basic theory about tenouchi and what it means, have a re-read of this.
Last Saturday we did a fun drill using a kind of kusari fundo, or weighted line. Usually this is a metal weight on the end of a chain, but we just used bean-bags on the end of cotton ribbon.
The exercise was to practice cutting by using the whole arm from the shoulder and not just swinging from the elbows. If you didn't do it properly, the bean bag didn't fly through the air in an arc. When done properly it was almost as easy as cutting with a shinai. Using the whole arm and shoulder meant the weight stretched out the ribbon and swung as if it were something rigid, like a shinai.
The other thing it did was to make you throw your cut forward, rather than down towards the ground. Above is a short vid of this exercise being practiced at this year's Kangeiko. I was going to put a picture, but the 'kusari fundo' is completely invisible in the still shot.
