“Only 8% of children and 6% of adolescents achieved the 30-minute recommendation for after-school moderate-to-vigorous exercise. In children, the type of dance really mattered.

Jazz took second place, followed by partnered class, tap, salsa and finally ballet, where 30% of class is spent in moderate-to-vigorous activity.”
