Abstract: This study assessed the level of exercise among college students and their reasons for not engageing in exercise. In this descriptive cross-sectional study, a self-administered questionnaire consisting demographic data and 20 scale-questions about exercise and reasons of physical inactivity, was designed based on Likert scale and ranking scale. The total number of 160 students who were studying in SSUMS were selected through cluster sampling. About 34% of the male students did not engage in exercise and 83% of the questions regarding the students` knowledge on exercise were answered. The most important reasons for this inactivity has been mentioned as study preoccupation and lack of time (197 Points). These findings on the students` attitudes about exercise suggest that a recommendation on planning public health interventions may be useful to increase exercise among the male students.
