Are your kids getting anywhere near the amount of physical exercise they need in order to be healthy? Health experts say children and teens should get about 60 minutes of physical activity a day, five or more days of the week. Despite those recommendations, only about half of those 12 to 21 get enough exercise.

At Hollidaysburg Junior High School, Physical Education teacher Wes McCloseky says "a lot of the kids are coming in a little more heavier a little more out of shape. You can tell they're not nearly as active as they used to be."

The Centers for Disease Control says since the mid-seventies, the number of overweight children has increased sharply. The number of overweight children two to five years old has gone from 5% to nearly 14%. Among six to eleven year olds, the number of overweight children has risen from six and a half percent to nearly 19% and for those 12 to 19, from 5% to 17.4%.

To fight that trend, Mccloskey keeps his classes moving with activities focusing on running. The school also takes a close look at what shape the kids are really in. Students go through a fitness testing program twice a year to assess their cardiovascular endurance, muscular endurance, and body composition.

The Hollidaysburg Area School District also has a cardio-room where students can work out with an eye toward improving their cardiovascular system.
