If you want to see all 24 hyungs (beginning with Chon-ji up to Tong-il) ... this is by far the best site that has pics from the pages of Taekwon-do by Gen. Choi Hong Hi http://www.karate-kids.com/lesson3.htm Every movement explained with diagrams and foot placements .... You can use together with the videos from the site that Chazz supplied
But if you are in a TKD school. Dont worrie about learing then so fast. Your Instructor will teach you the forms when you are ready.
