Physical education, or gym class, isn't mandatory for all high school students. In some schools, it isn't offered due to budget cuts or the idea that students should use that time to study. Physical education may actually increase academic performance. It also teaches teens skills and habits that help them transition to healthy adults.

Establishing Healthy Habits
Obese and sedentary teens are likely to carry their bad habits into adulthood. Teaching teens the importance of a healthy lifestyle and establishing fitness routines now can help teens make exercise a priority as an adult. Teens can also learn to use exercise as a healthy coping mechanism for academic and social stress. Physical activities, such as group sports, help build adult leaders and teach teens the value of teamwork and cooperation.
The American Heart Association is an advocate for physical education to help reduce childhood obesity. AHA estimates that 10 million kids and teens suffered from obesity as of 2011. Teens should get 60 minutes of physical activity per day to control their weight and to strengthen bones and muscles. The increase in sedentary activities among teens, such as video games and computer activities, means many teens don't get their required exercise. Physical education classes act as a public health measure to encourage activity and help teens maintain healthy weights.
Reduced Disease Risk
Inactivity and obesity increases the risk that teens will develop heart disease, diabetes, bone and joint problems and certain cancers as adults. An active lifestyle offers a substantial means of protection from these and many other preventable chronic health problems. On a global scale, widespread obesity-related disease prevention could save the Unites States billions of dollars in health care costs. As much as 75 percent of health care spending goes toward treating medical conditions that can be prevented with lifestyle changes, according to the American College of Sports Medicine.
Improved Academic Performance
According to the President's Council on Physical Fitness and Sports, students who performed five hours of physical activity each week improved their academic performance, alertness levels and attention spans. Students from programs with no physical activity who used the extra time for classroom study did not perform better on standardized tests than the students who gave up some study time in favor of physical education. The PCPFS also reports that brain scans of students who get regular exercise show increased activity in the parts of the brain required for learning and decision making.
