The 2010 Youth Risk Behavior Survey, which polled 8th, 10th and 12th graders in Arlington, found that more teens say they’re getting adequate exercise than three years ago, when the last survey was conducted.
In 2007, 40 percent of teens said they were getting adequate exercise — defined as at least one hour of exercise, five or more days per week. In 2010, that number jumped to 50 percent.
