This publication is designed to help high school students develop a lifestyle that promotes cardiovascular and overall health; activities are intended to promote total health and wellness. The handbook is composed of a curriculum guide and classroom materials, and is designed to fit into a comprehensive health education program. Multidisciplinary goals are to create growth in self-awareness, effective decision making, and responsible interaction in resolving problems or coping.
