The aim of this case study is to investigate the possibilities and limitations in relation to motivation in participation in a new workplace exercise program implemented at the Department of Civil Engi-neering at Aalborg University. On the theoretical basis of organizational culture, employee percep-tions of health and the motivation theories Self-Determination Theory and Health Belief Theory it’s attempted to identify the factors that determines whether the workplace exercise program is used or not. Exercise High-intensity Interval Training was implemented in the workplace exercise program, as this seems like an ideal way to break down the most common barrier in not being physically ac-tive - the lack of time. It only takes 10 minutes to perform a single set of HIT, and this is only has to be performed three times a week. HIT has been scientifically proven to cause beneficial health ef-fects as helping to prevent Type-2 diabetes, a number of cardiovascular diseases and to help improve the aerobic capacity. All 156 employees at the institute were invited to participate in the exercise regime, of which 30% chose to use workplace exercise program at least once during the four-week intervention period. The workplace exercise program has had a both enabling and constraining potential on the employees' motivation to exercise more, but in spite of many enabling trends, it turned out that workplace exercise program was not used to a great extent.
