Physical Activity Guidelines for Americans: Understand and apply the 2018 recommendations by Kathie C. Garbe, PhD, MCHES, and Mary E. Sanders, PhD, FACSM, RCEP, CDE

The Physical Activity Guidelines for Americans (PAG), initially launched in 2008, has served as the preferred source for policy, programming and funding for physical-activity programs throughout the United States for a decade. In 2018, based on the expertise of 17 nationally recognized leaders in health and physical activity, a second edition was published. These updated guidelines reflect more extensive, science-based guidance that further emphasizes how regular physical activity leads to improved overall health and reduces the risk of many chronic diseases. The PAG's second edition was motivated by new findings that regular physical activity over the long term can produce significant health benefits, especially in light of new data showing disturbingly low activity levels.
