Answer 1

• Regular physical activity reduces the risk of many adverse health outcomes. These are listed in the answer to number 2.
• Some physical activity is better than none. Even moderately active individuals have a lower mortality than sedentary individuals.
• For most health outcomes, additional benefits occur as the amount of physical activity increases through higher intensity, greater frequency, and/or longer duration.
• Most health benefits occur with at least 2 hours and 30 minutes (150 minutes) a week of moderate-intensity physical activity, such as brisk walking. Additional benefits occur with more physical activity.
• Episodes of activity that are at least 10 minutes long count toward meeting the guidelines.
• Both aerobic (endurance) and muscle-strengthening (resistance) physical activity are beneficial.
• Health benefits of physical activity occur for children and adolescents, young and middle-aged adults, older adults, and those in every studied racial and ethnic group.
• Health benefits of physical activity are attainable for people with disabilities.
• The benefits of physical activity outweigh the risks of injury and heart attack.
