Aikido, you're doing it wrong.

He's right, you know. Aikido is all about countering and using your opponent's weight and movements against them. It's a fantastic style to use against grapples, fairly potent against striking, and generally a style used purely for defense. Don't get me wrong, martial arts in general are about "self defense"... but Aikido is ALL about the defense and not so much the "beat someone's ass before they hurt you" things that other hard-striking styles often appear to focus on. Sloth, of all people, would know. He used to practice Aikido.
