This article presents the results of an investigation about perceptions of senior citizens who attended the physical activities workshops in the municipalities of Valparaiso and Vina del Mar (Chile). The main questions are 2: how do these workshops work and what are the reasons why senior citizens keep attending them. The approach of the study is a qualitative one (two discussion groups, one in each city, and five in-depth interviews). From the content analysis (inductively), the conclusion is that physical activities (and the continuity of them) are related with self-improvement, learning and joy of living attitudes.
