By playing.

Seriously, you won't get good for a few months, I'd reccomend playing in Multi for a while.

...... or you can find some crappy moves in the Wiki.
Ok well wiki helps as the person who will most likely get banned said before me.
Or you can take classes from Unibash and, or play multi-player and practice practice practice!
I played single player when toribash wasn't free. When it became free "or a few months after it did" I started playing multi player and I was a lot better than all my belts because of how much single player I played.
Faint has the right idea play until you learn or make up a good move for a good mod E.g. Twin Swords, Akimbo, Jousting or you could always play with a friend on a private server if your are sill allowed to make private servers?

but play
Single Player - Learning/Making Moves
Multi Player - Gaining Experience and Belts/ToriCredits and good fun

^^
In the beginning there was time.
In the end there was nothing......
Practice!
Also if you spec in higher belt tournies you can see how fights move, also spend time in single player working out what the joints do, instead of praying that they do what you want.

Hope this helps
