Dunsmore Elementary School physical education teacher Roger Sondergaard was standing in the middle of a makeshift track on the school playground calling out instructions.
"If you are wearing Dunsmore clothing jog on the inside," he directed through a microphone.
Circling around him was what looked like a swimming school of children, teachers and parents. Some were walking, some skipping, some running. All of them were smiling.
"It's sort of a fun way to start a Friday," said Dunsmore Principal Karen Stegman.
The La Crescenta Elementary School this year launched Fit Friday, a weekly event geared at teaching students about the importance of physical fitness and health. And it is keeping in line with the Dunsmore Elementary School PTA's theme of Give Back, Get Fit and Go Green.
Each Friday, students gather on the school playground at 8 a.m. — 15 minutes before the normal start time. And with the Isley Brothers' "Shout" and other classics blaring on the sound system, they put in 20 solid minutes of cardio.
