The Confucius Institute in Chicago is pleased to offer a taiji class. Taiji or taijiquan, sometimes called tai chi or tai chi chuan, is a noncompetitive, self-paced system of gentle physical exercise and stretching. To do taiji, you perform a series of postures or movements in a slow, graceful manner. Each posture flows into the next without pausing. Doing taiji helps to reduce stress, increase flexibility, improve muscle strength and definition, increase energy, stamina and agility and increase feelings of well-being.Yang Style Taiji is one of the most famous and popular taiji styles.
