Body health is the common aspiration of all human beings. Nevertheless, there are many different styles of fitness exercises, though prevalent in current society without, are lack of theoretical exploration as well as case analysis and therefore hard to examine their efficiency. Based on literary reviews and personal interviews, this research will explore Shing-Kuang Shih's " Four- realm Harmonized Fitness Exercise" and evaluate its efficiency. This research also analyzes the efficient range that Shih's fitness exercise may apply. This research points out that Shih's " Four- realm Harmonized Fitness Exercise " is a exercise developed from her interpretation of Buddhist theory of material properties. In Buddhism, health is achieved through harmonizing the four elements: earth, water, fire, and wind in the body. This Buddhist theory is echoed with and can be cross-referred to other medical sciences such as Ayurvedic therapy, Chinese, and Western medical theories. In Tripitaka, sutras that involve Buddhist medicine are around four- hundred volumes, which contents include medicine and health, disease records, psychological illusion, self-cultivation...and so on. Within these volumes, the relevant information about the Buddhist fitness exercises include master of the Sui Dynasty Zhiyi who proposed "Six Hearing Sound" for health and treatment, and Muscle Change Classic which Bodhidharma left. It also includes the Shaolin martial arts, a practice developed by ancient monks who referred folk martial arts and Chinese boxing at their time. Shih's fitness exercise has been promoted in two-day retreats and meditation camps for many years. This exercise is a set of simple motions and is easy for everyone to practice. Through field interviews, this research found that by practicing it dedicatedly, people who have suffered by chronic diseases can receive immediately positive effect, and many of them their diseases are even cured. This research argues that Shih's fitness exercise has its theoretical basis from both eastern and western medial theories. Though there is no such word "regimen" in Buddhism, there are quite some concepts related to body health. This research concludes that the philosophy and ethics implied in Shih's Four- realm Harmonized Fitness Exercise is : Body health is an important aspect of life and everybody should cultivate it well. Having a healthy body, we not only do not increase the burden of others, but also positively make the body more able to contribute to society and help others.
