The control group will receive leisure activity in a group setting for one hour three times a week for 12 weeks. The sessions will be held at the same weekdays and about the same hours as the exercise group sessions. The same group leaders as in the exercise sessions will participate in leisure sessions and will support the adolescents through reminders and reassurance before and during the sessions to enhance adherence. The sessions will start with a check in on feelings, recent events and difficulties (i.e. supportive listening but not any interventions) followed by non heart rate increasing activities, such as playing games or cards together
