Academic performance at school linked to exercise

No doubt (except training, not exercising, is what works - see below).

How well children perform in the classroom could be linked to how physically active they are, suggests a Dutch review of previous studies.

Writing in Archives of Pediatrics & Adolescent Medicine, researchers said they found strong evidence of a link between exercise and academic performance.

The review looked at 14 studies involving more than 12,000 children.

Healthy mind, healthy body.

But train. Don't exercise.

Exercise is useless or worse.
