The aim of present randomized controlled trial is to evaluate the health effects of physical activity in transport and leisure time domains of everyday life and to develop durable physical activity regimens, i.e. to go from lifestyle intervention to daily lifestyle routine, in overweight individuals.
Subjects will be randomized to 1 of 4 groups. 1: Vigorous intensity leisure time physical activity, 2: Moderate intensity leisure time activity, 3: Active commuting by bicycle, or 4: a non-intervention control group
