Investigating the Effectiveness of Exercise Coaching on the Physical Activity Behavior of Physically Inactive Employees.

After measuring physical actity, physical fitness level, anthropometric and psychosocial variables a personalized 12 week physical activity program is made (=baseline). The intervention consisted of two face-to-face counselling sessions at the start of the intervention, short contacts by e-mail or telephone at weeks 3, 6 and 9, and two face-to-face counselling sessions at the end of the intervention. Employees exercise on their own. After 12 weeks and 6 months all measures are repeated.
