Hey, everyone. I was just wondering if any of you know of a good resource, be it a book or website or whatever, for a solid Taekwondo curriculum. I am an upper belt now, but I feel like my teacher has been winging his lesson plans for a long time, and I'm not really learning anything new. I want to be a better martial artist, but I'm not sure how to proceed on my own, so any advice would be appreciated.
