Yang style tai chi involves a series of movements performed in a slow, focused, manner and accompanied by deep breathing. Tai chi, also called tai chi chuan, is a noncompetitive, self-paced system of gentle physical exercise and stretching. Each posture flows into the next without pause, ensuring that your body is in constant motion.
The long form consists of a sequence of 108 moves, and is useful for stretching and meditation, like other yoga forms. It generally takes a few months to learn, although the first section can be learned in a few weeks.
