Whether it's going for a run or to a yoga class, playing basketball with friends, or spending an afternoon doing yardwork, moving our bodies regularly is vital for both our physical and mental well-being. This book explores the different forms of exercise and physical activity, their benefits and risks, why so many people find it difficult to be physically active, and how to create and maintain a healthy, sustainable plan for physical activity.

Prevalent myths and misconceptions are identified and dispelled, and a collection of case studies illustrates key concepts and issues through relatable stories and insightful recommendations. Each book also includes a section on health literacy, equipping teens and young adults with practical tools and strategies for finding, evaluating, and using credible sources of health information both on and off the internet-important skills that contribute to a lifetime of healthy decision-making.
