Nowadays, people have realized that physical activity plays a critical role in determining the health and wellness of an individual. This is proven by the extensive research on this area, which indicates that people have started to emphasize this matter. In addition, it is also well known that motivation is one of the main factors that determine whether people will participate in performing physical activity or not. Both extrinsic and intrinsic motivators play a major role in determining levels of physical activity. Therefore, this study is made to investigate the relationship between extrinsic motivation and physical activity level. The researcher randomly selected 195 students from SMK Alam Megah 2, Seksyen 28, Shah Alam, Selangor as respondents for this study. The method of this study includes a questionnaire adapted from International Physical Activity Questionnaire (IPAQ) and Exercise Motivation Inventory (EMI), which was edited to fulfil the requirements of this study.
