Family doctors often face requests to exempt adolescents from physical education classes. Knowledge of the goals of physical education in compulsory and post-compulsory education can help the practitioner discuss this important subject and its physical and mental health implications. In Geneva, an innovative programme called "EPI" (individualised physical activity at the secondary school level) has been developed and doctors can refer adolescents who otherwise would not be able to participate in conventional gym classes. Motivational interviewing techniques the "motivational interviewing pyramid for young people" are useful to help the practitioner during these consultations.
