Yang style tai chi uses the slow, large movements that most people associate with tai chi. This style has become popular with people who want a low-stress form of exercise. Some of the physical benefits that tai chi promotes include increased muscle strength, increased flexibility, and better physical coordination. There are some suggestions that tai chi may also aid in treating high blood pressure, stomach ailments, and heart disease but there is not enough clinical data to support these claims.
Tai chi combines awareness of breathing, meditation, and physical movements, and is believed to be grounded in the Taoist tradition. The concept of yin and yang — polar opposites contained within the whole — and the idea that all things are connected by an invisible force called qi are key elements in virtually all styles of tai chi. Regardless of style, the general goals of tai chi are to bring yin and yang into harmony in order to allow qi to flow.
It is also important to note that although tai chi is a relatively low impact exercise, anyone with a serious health concern should consult a physician before participating in tai chi.
