The purpose of this research was prediction Stages of Exercise Behavior Change based of Decisional Balance and self-efficacy in students. Exercise Behavior Change include five stages: Precontemplation, Contemplation, Preparation, Action and Maintenance. The number of 292 male and female students in Shahid Beheshti University were selected. Then, they completed Stages of Exercise Behavior Change (SEBC) (Cardinal, 1997, self-efficacy (Schwartz, 1999) and Decisional Balance (Plotnikoff, 2001) questionnaires. Multiple Discriminates Analysis showed that 83.2 percent of the variance of the SEBC is explained by decisional balance and self-efficacy. These variables make up a significant predictor model (P=0.02). Based on these results, Decisional balance and self-efficacy variables have main role in the differentiation of 5 clusters (SEBC). The results show awareness has crucial role in perception advantages and disadvantages of practice; this role emphasizes on the positive training experience.
