ITF Patterns

Patterns, or tul (틀) in Korean, originally called hyeong (형), form an important aspect of training in Taekwon-Do. ITF Patterns (tul) are performed in accordance with “The Encyclopedia of Taekwon-Do” in 15 volumes written by General Choi Hong Hi. ITF Patterns also known as Chang Hon-style .

There are also three fundamental exercises, named Saju-Jirugi (Four Direction Punch), Saju-Makgi (Four Direction Block) and Saju Tulgi (Four Direction Thrust). Saju-Jirugi and Saju-Makgi are basic defence exercises taught to beginners of the martial art. Saju Tulgi is less well known and is generally taught to 2nd Kup students just prior to Hwa-Rang. Saju Tulgi is not presented in the Condensed Encyclopedia but is present in the 15 Volume Encyclopedia

The 24 patterns represent 24 hours, one day, or all of my life.
