A fit kid is a smart kid.
That's the findings from a new report.
It looks at how exercise stimulates a child's mind and body.
The study appears in the Journal of Pediatrics.
Kids who are in good shape are more than twice as likely to pass standardized math and reading tests.
That's compared to kids the same age who aren't fit.
That link was obvious regardless of the child's family life.
The researcher team says physical education should get as much emphasis as academics.
