Physical activity is part of a healthy life-style and part of primary and secondary prevention. Wellness is a life-style aiming at health and is characterized as a life-style leading to a pleasant and satisfactory life every time. Wellness consists of five parts. One without the other does not lead to a healthy life-style. Wellness consists of a positive approach to life, personal habits, nutrition and weight maintenance, stress management and fitness. Individual parts should be developed independently and at the same time simultaneously in certain link-ups and coherences. Wellness and a good level of physical fitness depend on one having a fully functional cardiovascular system, adequate body weight, optimal muscular strength and joint mobility. It is understandable that these things change according to age, sex and health state (including the psychological state) and that they also depend on the type of occupation, the prevailing way of daily active movement of the organism and on many other circumstances. Physical fitness can be gained only by practising a suitable physical activity. The physical activity theory is part of the teaching at the University of Hradec Králově and at the Medical Faculty of Charles University in Hradec Králové. At the Pedagogical Faculty it is taught within the subject of “Wellness“ and within “The University of the 3^rd Age Programme“ (special programme for senior citizens). At the Medical Faculty it is included in the pregraduate teaching of the general and stomatological study branches and also in the teaching of the bachelor study branche. The present method of teaching will be modernized for better illustration and link-up by using multimedial technologies.
